Dynamic simulation models are indispensable tools in agricultural research and management. Modeling makes possible to investigate the consequences of probable future scenarios and to be ready for the changes before they occur. The objective of this study is to predict corn yields in Red Ferralitic soil in Alquizar region under the SSP1-2.6 climate change scenario and the Hadgem3, Mpi-esm1 and Mri-esm2 models with the use of the AquaCrop simulation model. To select the hydrological years, a study of a series of 28 years (2023-2050) was carried out for the period November-April (crop development period) for each model. The possibility of achieving potential yields of 8.6 t·ha-1 and an agronomic water productivity of 3.08 kg·m-3 in corn is evident, if the crop is not subject to any type of limitation except plant genetics, solar radiation and temperature, and rainfalls are sufficient in this dry period. If irrigation is applied only to guarantee corn germination under the SSP1-2.6 scenario, yields are estimated at 4.4 t·ha-1 and biomass at 14.6 t·ha-1, achieving a productivity of 2.37 kg·m-3, with reductions with respect to potential performance of 44 %. The comparative study of yields in the SSP1-2.6 climate change scenario and the different models demonstrates the influence of these conditions on the crop response. The results show the AquaCrop model as an alternative to evaluate the impact of climate change on crop yields. [ABSTRACT FROM AUTHOR]

Adolescence Germplasm banks are a way of preserving the genetic diversity of both animal and plant species. In the latter, seeds, tissues and DNA sequences are stored for use in production, conservation of rare or endangered species, and agricultural research. For Arguello et al. (2021) "are an option to guarantee the availability of seeds and, consequently, food production" (p. 119). Likewise, they can also be a way of promoting those native crops that are little attended to in the field of research. Aware of the importance of this issue, the Food and Agriculture Organization of the United Nations (FAO, 2014) publishes the standards for germplasm banks of plant genetic resources for food and agriculture, which provide international guidelines for ex situ conservation in seed banks, field germplasm banks and in vitro conservation and cryopreservation banks. For the reasons described above, this essay addresses the generalities of germplasm banks, emphasizing their use and importance for food production and access. [ABSTRACT FROM AUTHOR]

The precise determination of the coefficients of the Class A evaporimeter tank allows us to estimate the reference evapotranspiration (ETo) and obtain real values of water needs of the crops. In the present work, the Kp coefficient was estimated using the two equations proposed by FAO, Snyder, Orang, Cuenca and the ETo Ratio determined by the Penman-Monteith (PM) method and the Eo determined in the class A evaporimeter. For the estimation of Kp, the climatic data from the climatic station of the Agricultural Engineering Research Institute in Alquizar for the period 1975-1990; with these coefficients, the ETo was calculated from evaporation data for the period 2019-2022, which was contrasted with the ETo estimated by the Penman-Monteith equation; the statistical parameters were determined for the cross analysis between the different methods to estimate ETo: mean absolute error, coefficient of agreement, efficiency and the coefficient of determination. The statistical parameters applied in the validation of the models indicated greater precision in the estimation of ETo for the decadal values with the FAO 1 equations and the ETo/Eo relationship, while for the monthly values these two models and the Cuenca model. It is recommended, due to its ease of obtaining, the use of the Kp obtained by the ETo/Eo model for the determination of the ETo in the region studied. [ABSTRACT FROM AUTHOR]

Livestock farming is an activity of greater importance from an economic, social, cultural and environmental point of view, it contributes to the gross domestic product and generates employment. Production is affected in the dry season due to food shortages. For this reason, at the Portoviejo Experimental Station of the National Agricultural Research Institute, corn genotypes are evaluated for the production and conservation processes of forage in the form of silage. The test was installed at the Porvenir of Toachi facility, canton Santo Domingo, province of Santo Domingo de los Tsáchilas. A divided plot design was used, with a 3x4 factorial arrangement, each treatment consisted of six ten-meter-long beds. The information was tabulated in the R program under the analysis of variance with separation of means for the multiple test of DGC probability at 5%. The hybrid INIAP 554 at a density of 125,000 plants per hectare obtained the best yield of green forage (29,028.59 kgha-1) and the highest average dry matter (30.5%) of the silage, the hybrid INIAP 551 at a density of 125,000 plants per hectare presented the lowest lodging values (3%). There were no significant differences for germination percentage, days to male flowering, plant height and fermentative characteristics of the silage. It is concluded that the hybrid INIAP 554 at a density of 125,000 plants per hectare, produces a greater amount of green forage, under the climatic conditions of Porvenir of Toachi.

The aim of this article is to analyse how, during the period of 1937 to 1961, different Mexican governments used the cultural and ancestral dimension of maize, overcoming the controversies around its nutritional quality and utilising the benefits of agricultural research, to incentivise its production and consumption among the population, as well as its exportation to other countries, with the goal of turning it into a commodity that would incorporate the rural population into the national economy. For this reason, it was important to design campaigns to promote this grain in various media, seeking to exalt the idea of the ancestral food that was the basis of the Mexican diet and a symbol of Mexican culture. This analysis was constructed using contemporary newspapers and other publications of the period mentioned, as well as works that have addressed the topic of maize cultivation and consumption. The article seeks to deepen our understanding of the changes in the Mexican diet, the practices of production, and the sociocultural significance of maize as from the mid-twentieth century.

The management of edaphic and foliar fertilization. as well as its application according to the changes generated by soil mechanization are determining factors in corn production. The objective of this research was to evaluate the effect of mechanization and fertilization of corn on soil physical properties and yield. The trial was conducted at the soil department of the National Institute of Agricultural Research (INIAP). The experimental design used was completely randomized blocks design with three replications. It was possible to identify that the agronomic behavior of the crop varied in each treatment for the variables stem diameter and plant height. however. the weight of 100 seeds and longer cobs were presented in T6: NPK+ SL + CFF. (51.15 g and 17.05 cm) and the diameter of the cobs was greater in T8: NPK + CL + CFF (4.79 cm). The combination of complete fertilization in no-tillage and in the absence of foliar fertilization allowed obtaining a higher yield level in the maize hybrid under study (3,597.86 kg ha-1). The economic benefit was higher when combining complete fertilization with no-tillage and no foliar fertilization. with a 64.05% profitability. [ABSTRACT FROM AUTHOR]

The reception of the Libro de Agricultura is examined in the second edition of the Diccionario de Autoridades. The academic review of the first repertoire caused amendments in those agricultural articles that were lemmatized and, as a result of this modification, were incorporated in the Alonso de Herrera's authority in 1770. Simultaneously, the emptying of the geoponic treaty involved the addition of new entries under his authorization. The microstructural analysis of the amended articles demonstrates their readjustment in the notation, definition and Latin equivalents, as well as in Alonso de Herrera's authority review to suit the lemmatized senses. The study of contexts that have been put forward, as well as the remodelled ones, after the comparison with the versions of Alonso de Herrera's book, printed between 1513 and 1768, reveals the preferential use of the first editions to illustrate geoponic technicalities and the alteration of passages, particularly the parenthetical paragraph introduced to contextualize the quote.

There are different theoretical models on innovation processes, but little has been studied on the actual practices of researchers in these processes. This paper describes the role played by researchers in the framework of innovation and rural development processes by analyzing tensions between real and ideal practices. Fifteen researchers from the National Institute of Agricultural Technology in the northeastern region of Argentina were interviewed. The results show that models of innovation coexist in the real practices and in the ideal role described by the interviewees. The importance of generating spaces for reflection to rethink their role to enhance innovation processes is highlighted. [ABSTRACT FROM AUTHOR]

Despite the importance of field trips and experimental works in plant health, Agronomic Engineering and similar careers lack these types of activities in their programs. To address this deficiency, we developed a proposal based on an experimental class using soil seed banks (SSB) to promote the study of the biology and ecology of weeds in an undergraduate course for aspiring agronomists. During the development of the proposal, the students collect samples from the SSB in an agricultural-livestock field subjected to different types of tillage and through a methodology that combines field trips, laboratory work and statistical processing of results, evaluating different aspects of the SSB of the study area with the delivery of a final report of the experience. The proposal uses low-cost materials and equipment that are commonly present in any university laboratory, the methodology is simple and easily reproducible, as well as free of risks to human health, being applicable in any university or secondary school. This set of experiments should help students to develop different skills such as the management and design of experimental trials, to promote their ability to discuss and solve practical problems, as well as to draw conclusions from their observations and the results obtained. Finally, this practical activity puts them in contact with their future professional career and also gives them a chance to start in the field of research. This proposal aims to increase the ability of students to solve problems using flexible scientific methods and develop skills such as handling experimental trials and discussing their observations or results obtained.

The present research project was developed at the Pichilingue Tropical Experimental Station of the National Institute of Agricultural Research (INIAP) and at the Bromatological Analysis Laboratory of the UTE University. The effect of nitrogen fertilization with urea (0, 25, 50 and 75 kg of N ha-1) on in situ ruminal degradability (bioavailability) of the macrominerals (Ca, P and Mg) was evaluated) of the King Grass harvested at 40 days of regrowth. A randomized complete block design was used for the statistical analysis, where the blocking criteria was the animal where the ruminal incubation was performed, respectively. Nitrogen fertilization levels caused changes in ruminal bioavailability (degradation) of Ca, P and Mg of Pennisetum purpureum grass at different incubation hours, an action that in most cases affected the degradation kinetics of the grass in their different fractions (soluble fraction (A), insoluble but potentially degradable fraction (B), unpleasant fraction (c). Potential for ruminal degradation (A+B). [ABSTRACT FROM AUTHOR]

Through the review and systematization of specialized historical bibliography and information collected from the mass media and exploratory interviews, in this article we seek to identify and analyze the emergence and becoming of access to land of family farming as a 'question' throughout Argentine history. In line with our analytical theoretical perspective on public policy, which is based on the social process that is orchestrated around a "socially problematized issue", we set ourselves this objective. We conclude that it is a problem whose origin dates back to the founding moments of the Argentine nation-state and therefore we carry out a historical review. In this sense, we consider that it is a matter historically problematized by the family farming sector in Argentina. [ABSTRACT FROM AUTHOR]

Introduction: Organizational resilience has become a new and important change in management studies and practice. Seen as the ability of organizations to assimilate changes and ruptures, both internal and from the environment, without their results being affected, implies the need to manage it strategically, which includes evaluation processes applying various instruments. Objective: Present the results of the application of an organizational resilience assessment approach in an agricultural cooperative. Methods: The dialectical-materialist method was used as a fundamental method. Surveys, interviews, documentary review, economic-financial analysis and the construction of the Vanistendael house were also applied. Results: When applying the instruments in the Jesús Suárez Gayol CPA, the potentialities and shortcomings of the cooperative in terms of the creation and development of organizational resilience were identified. It is shown that the cooperative has various sources to increase its resilience capacity. Conclusions: The study made it possible to define that the CPA shows comprehensive results that can be increased to enhance its resilience capacity; the instruments applied allowed us to identify ways to do so.

Objective: To evaluate the nutritional quality and acceptability of five cold-climate grasses: Holcus lanatus (L), Bromus catharticus (Vahl), Festuca arundinacea (Schreb), Cenchrus clandestinus Hochst. ex Chiov (naturalizado), Dactylis glomerata, associated with Lotus uliginosus (Schkuhr) in the high tropic of Colombia. Materials and Methods: The work was conducted in the Marengo Agricultural Center, of the National University of Colombia. A randomized block design was used, with split-plot arrangement. The association and regrowth age of 45 and 70 days was taken into consideration. The nutritional quality of each accession was analyzed: crude protein, neutral detergent fiber and acid detergent fiber and in vitro dry matter digestibility. After one year of establishment, a cafeteria test was carried out with heifers (300 kg of live weight) to calculate the relative acceptability index). Results: Due to their high crude protein content, associated C. clandestinum (naturalized), D. glomerata and F. arundinacea, stood out (p < 0,01), compared with the other grasses and the pure control. In general, all the samples of L. uliginosus showed good nutritional content, with high values of protein (26,5 %) and in vitro dry matter digestibility (68,6 %), especially. Conclusions: The association that showed the highest relative acceptability index was C. clandestinus (naturalized), being also the one with the best CP content and digestibility. F. arundinacea stood out as the promising material for the establishment in associations with legumes, due to its nutritional quality and compatibility with the legume. [ABSTRACT FROM AUTHOR]

The world needs more agricultural products and food. At the same time we have to comply with the sustainable development agenda: economically, ecologically and socially responsible. A paradigm shift is necessary, not just a modification of practices and investments to do more of the same. For this, the sustainable intensification of the agricultural production is essential, playing a determining role the efficient and effective management of the engineering systems that are used. This objective is achieved from a strategy of use and maintenance of the equipment that intervenes in these processes in extensive agriculture and in organic agriculture based on biodiversity. In Cuba the social order of the management of the agricultural production processes with the use of technologies is fulfilled by the Agricultural Engineer, whose training plan has its origin in the Mechanical Engineer of agricultural production, constituting a key profession for the development of the country. The present work aims to identify the evolution of university education models and the trend of Agricultural Engineering that has accompanied this profession in recent years in Cuba, inviting them to reflect on their future in their teaching and research aspects.

A study whose purpose was to evaluate the performance of the extension workers in charge of providing technical assistance to amaranthus producers within the agricultural extension program at Mexico City (CDMX) to implement technologies in their productions units that improve their productivity to increased yield and/or reduced production costs. The entities responsible for the program were the Ministry of Agriculture and Rural Development (SADER), before (SAGARPA) and the Ministry of Environment and Rural Development (SEMADER) of the Government of CDMX. In addition, it was supported by two institutions; one dedicated to the training of rural producers and one of research, the first in the methodological part that fell to INCA Rural and the second, in the National Institute of Forestry, Agriculture and Livestock Research (INIFAP) that accompanied the extension workers in the part of research and innovation. Six technical advisers (extension agents) and a coordinator participated in the development of their activities in the town hall of Milpa Alta, Tlahuac and Xochimilco, where a population of 84 producers were directly assisted, which implemented 20 innovations in the primary links, transformation, commercialization, supply inputs and organization of producers. The technological innovations that were implemented for the amaranth crop had a small scope of application, because the number of extensionists assigned to the chain of such crop was very scarce.

The production of bananas (Musa spp.) has increased worldwide and demand for many inputs, so it is necessary to introduce productive and disease-tolerant cultivars. An investigation was carried out with the objective of evaluating the agronomic response of banana plants 'FHIA- 17' (Musa AAAA) obtained by tissue culture and agamic propagation. 'FHIA-17' plants from micropropagation and agamic propagation were evaluated in the field under production conditions. Plants of cv. 'Grande naine' (Musa AAA) obtained by micropropagation were use as reference. Plant materials were compared in terms of the duration of the planting-flowering and planting-harvest cycle. At flowering, plant height (cm), pseudostem circumference (cm), number of total and functional leaves, and response to black Sigatoka were evaluated. As yield indicators, the net weight of the bunch, number of hands and fruits per bunch were determined. The 'FHIA-17' plants showed the phenotypic characteristics according to the descriptors of the cultivar and the micropropagated plants were superior to those from agamic propagation in all the indicators evaluated, except in the number of leaves, which was similar. Both the plants from micropropagation and those from agamic propagation had a superior response compared to the cultivar 'Grande naine' and could be an alternative for banana production in Cuba.

A diagnosis of the blackberry (Rubusglaucus Benth) production chain was made in the municipality of Pamplona, Colombia, using a mixed approach. In quantitative terms, the following variables were studied: research, good agricultural practices and post-harvest management. Qualitatively, the weaknesses of the production chain and the improvements required were studied, based on interviews with experts. As a result, it was obtained that the blackberry productive chain presents strengths, such as: sufficiency of spaces for sowing, adaptation and yield of the fruit to the soils, considerations of the medicinal and nutritional value of the product, among others. However, there are critical points regarding to the genetic improvement of crops, lack of routines for water analysis and adequate disinfection, along with bad practices in the technical management of the crop. It is also evident that producers do not use administrative tools or keep accounting records to guide decision-making. [ABSTRACT FROM AUTHOR]

This paper presents the design and implementation of an isolated microgrid developed in La Guajira, north of Colombia. It was designed through the collaboration and capacity building of the community itself. Several activities were developed by the research group in order to improve the technical design. With the objective of reaching a consensus in terms of the final desgin, several visits were made to the community. During the implementation, some new ideas on how to improve the design appeared. In any case, if the microgrid (that uses both solar and wind energy) would be replicated in any other location, we strongly recommend to include, from the beginning, the community needs and the ideas of its inhabitants.

Biodiversity and the lack of technification in agricultural processes created the need to establish key strategies to stimulate agricultural production improvements in Colombia. Sáenz Fety has successfully designed and incorporated seven elements into its strategy to increase agricultural production capacity, stimulate greater and better consumption of local products and, of course, expand possibilities for exporters. These elements, based on investment in research and development and innovation, are essential to transform company growth from incremental into exponential or even disruptive growth. This article discusses in detail the seven key elements and their impact on productive use of agricultural supplies in Colombia, which are: product personalization, the decrease in aversion to technology, process replicability, in-situ market tests, interaction with academia, new market creation and interdisciplinary work.

The work was carried out on a Brown Soil type soil in the Intensive Garden of the Knife Productive Unit belonging to the Agricultural Company "Juan Manuel Márquez", Media Luna municipality, Granma province, with the objective of evaluating the effect of Enerplant® oligosaccharides on the performance and onion quality indicators, variety "Elan H-9". The experimental design used was random blocks with six treatments and three replications. The experimental data were subjected to a variance analysis of double classification and multiple comparison of means by the Tukey test. The agricultural yield and the average fresh mass of the bulb of the onion were higher in the dose of 1.3 mL ha-1 with 16.12 t ha-1 and 120.99 g respectively. The Enerplant® oligosaccharides improved the quality of the onion, achieving significant increases in total soluble solids, polar and equatorial diameter of the bulbs; In addition, the pH was increased and the titratable acidity reduced, compared to the control. The greatest economic impact of this organic product is achieved with the dose of 1.3 mL ha-1with a gain of $ 50 949.78 ha-1. [ABSTRACT FROM AUTHOR]

The experimental results under controlled conditions for the determination of the suction height appropriate for the tomato cultivation variety (F1-FA572) subjected to irrigation by suction with ceramic porous capsules are presented. The suction height (h = -15 cm) was found like the most appropriate for the capsules characteristics and soil employees in the experiences. The selection criteria were the number of fruits observed. The vegetative growth of the crops (plants height), the daily water consumption and the number of fruits per plant were observed. Values approximately coincident of water consumption by the crop perspiration were found. [ABSTRACT FROM AUTHOR]

The Journal of Agricultural and Environmental Research (RIAA) is an editorial project of the National Open and Distance University (UNAD) that began in 2009 with the aim of communicating the results of original research in the agricultural and environmental field. The journal seeks to maintain and strengthen trust between researchers and the public interested in these topics, and aims to be included in national and international databases and indexing systems. RIAA's mission is to promote communication and collaboration among national and international researchers, and its target audience is those interested in agricultural and environmental sciences. The journal is published semi-annually in both print and electronic formats with open access. [Extracted from the article]

The aim of this research was to determine resistance reaction of 14 Musa genotypes against Mycosphaerella fijensis, causal agent of Black Sigatoka disease. Two experiments were conducted in laboratory and shadehause at Pichilingue research Station from the National Institute of Agricultural Research (INIAP), Ecuador. Genotypes considered were: Orito (AA), Guineo de jardín, Williams, Filipino, Gross Mitchel, Mulato and Morado, (AAA); Limeño, Maqueño, Dominico, Dominico-Hartón, Dominico gigante, Dominico negro and Barraganete from the AAB genome. Two inoculation methods were used to asses' resistance: a) in vitro inoculation over leaf fragments with a conidial suspension, and b) inoculation of eight weeks old seedlings with a mycelial suspension of the fungus. In the first case, the incubation period (IP) and the number of lesions at 14 and 20 days after inoculation (DDI) were measured. For in vitro trial, the incubation period (IP) and the number of leaf lesions 14 and 20 days after inoculation (DDI) were measured, and for seedlings, PI, period of symptoms evolution (TES) and time for disease development (TDE) were recorded. Statistically significant (p ≤ 0.05) differences were found for all variables. Cultivars Orito (AA) and Limeño (AAB) qualify as resistant while all the others were susceptible, though response to inoculation within the latter group showed a range of variability.

The aim of this study was to show that repeatability is statistical value related with the experimental precision in the analysis of experiments. A database of the rice project of the Agricultural Research Institute of Panama was used. 379 individual experiments were analyzed, grouped in 41 trials, planted in the main rice growing-areas in Panamá, between the years of 2000 and 2014. The variance components were calculated through the individual and combined REML analysis, statistical calculations were performed, like the variation coefficient (VC), minimum significant difference (MSD), repeatability (H), range, determination coefficient (R2) and the MSD/range ratio. To determine the appropriate repeatability values to incorporate the combined analysis and improve the experimental precision was done several times throughout the analysis. The individual and combined analysis showed a link between MSD/range ratio and repeatability. When discarding the sites with H<0, the precision was raised by 60% with trial discards under 0,20, 0,30, 0,40 y 0,50, and the precision levels were 38, 67, 56 y 50%, respectively. A convenience in including sites with H>0,20 was confirmed, and discarding those with lower H. There was a lineal link between the number of locations and repeatability, an increase in locations and repeatability, improving the precision. The link between number of locations and MSD/range was inverse, when raising the number of locations the proportion in MSD/range was lowered, increasing the experimental precision.
