Cotton is one of the main crops explored commercially, moving several sectors of the economy, generating employment and income. The soaking of seeds in organic substances is a promising alternative for the vital processes of plants. Pyruvate, for example, is a crucial element in cell respiration, influencing the growth and development of the culture. Given the above, the objective was to evaluate the morphophysiology of cotton genotypes submitted to pyruvate supplementation via seed pre-soaking as a reinforcement of the energy mechanisms of plants. The treatments resulted from the combination of two cotton genotypes (BRS Jade and Line MT 2009-152) and five concentrations of pyruvate (0, 11, 22, 33 and 44 mM) applied via seed presoaking, distributed in randomized blocks. In a 2 x 5 factorial scheme, with 4 replications, totaling 40 experimental units. Seedling emergence, initial plant growth, gas exchange and phytomass accumulation were evaluated. Pre-soaking seeds in a calcium pyruvate solution starting at a concentration of 11 mM increases the rate assimilation of CO2, while, for emergency variables, growth and dry mass accumulation varies between 11 and 22 mM, reinforcing the energetic mechanisms of cotton genotypes BRS Jade and MT 2009-152. Evidently, more studies will be needed to test and validate the adoption of this technology. [ABSTRACT FROM AUTHOR]

Under salt stress, plant growth and development are negatively affected due to physiological changes, requiring strategies such as fertilization management to minimize these effects. In this scenario, this study aimed to evaluate the effect of combinations of nitrogen, phosphorus, and potassium on the growth, leaf water status, electrolyte leakage, and gas exchange of West Indian Cherry grown under water stress in the second year of production. The experiment was conducted in a protected environment in Campina Grande - PB. The treatments were distributed in a randomized block design with a 2 × 10 factorial arrangement with three replications corresponding to two electrical conductivity levels of irrigation water-ECw (0.6 and 4.0 dS m-1) and ten combinations of fertilization with nitrogen, phosphorus, and potassium (80-100-100; 100-100-100; 120-100-100; 140-100-100; 100-80-100; 100-120-100; 100-140-100; 100-100-80; 100-100-120, and 100-100-140% of the recommendation in the second year of production). Irrigation with the ECw of 4.0 dS m-1 negatively affected plant growth, the leaf water status, electrolyte leakage, and the leaf gas exchange of West Indian Cherry. However, the 40% increase (C4 -140-100-100% of the recommended N-P2O5-K2O level) in the nitrogen level mitigated the deleterious effects of salt stress on the relative water content, internal CO2 concentration, and the CO2 assimilation rate of West Indian Cherry plants in the second year of production.

The cultivation of radish in an organic system has potential for production to such a degree that alternatives of cultivation have been used to improve productivity in relation to fertilization. Therefore, the objective of this work was to evaluate the effect of organomineral fertilization on gas exchange, growth, and production of radish. The experiment was carried in nonclimatized greenhouse crop, with a metallic structure in form of arc, covered with 150 mm lowdensity polyethylene, in greater length-oriented East-Oste direction of Science and Technology Center of Federal University of Campina Grande, using the Crimson Gigante variety. The soil used experiment was fluvic neosol. The experimental design used was the completely randomized with three replications, using the Crimson Gigante variety. Seven treatments were used, which consisted of three doses of cattle manure (37.5; 75.0, and 150g per pot), three concentrations of biofertilizer (5; 10 and 15%), and mineral fertilization. This work analyzed the characteristics of growth, production, and gas exchange. The treatment (5% biofertilizer) provided greater height of the radish plants, however, the (75.0g manure per pot) resulted in a higher number of leaves. The concentration of 10% of the biofertilizer, obtained the largest diameter, fresh and dry matter of the tuberous root. The treatment presented higher fresh and dry matter of the leaves when compared with the other treatments. The use of organic fertilizers promoted greater production in the radish crop and can be used as an alternative to conventional fertilization. [ABSTRACT FROM AUTHOR]

Cotton is one of the largest agricultural commodities that generate various sources of foreign exchange and employment worldwide. However, water deficiency is an environmental factor that limits the production of this crop, especially in semi-arid regions. We evaluated pyruvate supplementation to mitigate the effects of water stress on colored cotton. Experiments were conducted in a greenhouse. We studied two forms of pyruvate supplementation (SP1-via seed and foliar and SP2-only via foliar); three conditions of irrigation management of the plants: water restriction in the vegetative phase (VE), flowering (FL), and vegetative and flowering (VE/FL); and additional treatment (total irrigation throughout the crop cycle and without pyruvate supplementation). The experimental design included a randomized block in a 2 × 3 + 1 factorial scheme. The factors resulted in seven treatments with three replications, with a total of 21 experimental units. Gas exchange, enzyme activity, and production of components were evaluated. Water restriction in the vegetative phase does not cause losses in BRS Jade cotton when supplemented with pyruvate. However, in the flowering and vegetative phases plus flowering, it reduces gas exchange and production components and increases the activity of antioxidant enzymes in relation to plants under full irrigation. Supplementation with pyruvate via seed plus foliar (SP1) was better for BRS Jade cotton grown under water restriction. [ABSTRACT FROM AUTHOR]

Nowadays there is a great technological evolution making it fundamental to provide information for different mobile devices with differently developed platforms. This evolution has given to the tourist area the expansion of its means of communication through all the technological media available. However, because it is a gigantic area and has different solutions for different situations, there is a large amount of data that needs to be filtered, so it has become slow to use a variety of solutions that search for destinations, verify reputation and create an itinerary. We look for with this work as a way to solve this demand the development of a computational solution that centralizes all tourist information. A mobile application and a Web Service were built that, through the Representational State Transfer (REST) architecture, uses transfer protocols to communicate. The results obtained demonstrate a significant efficiency of response time and agility in relation to the other solutions discussed. All data were validated in the laboratory based on a real case study in a small tourist town. [ABSTRACT FROM AUTHOR]

Background This study investigates the marine macroinvertebrate fauna of rhodolith beds (nongeniculated red corallinaceaous algae) in northeast Brazilian. A total of 57 species were identified, belonging to six phyla (Platyhelminthes, Annelida, Sipuncula, Mollusca, Arthropoda and Echinodermata), of which 50 are considered here as new records for the Paraíba State. Annelids (Class Polychaeta) were the most representative taxa in Miramar and Seixas Beaches, while molluscs were dominant in Maceió Beach. [ABSTRACT FROM AUTHOR]

Corn (Zea mays L.) is one of the most cultivated crops in the world. In Brazil, this cereal has a wide diversity of use. Most of the areas where maize production is used is irrigation, however, when performed inadequately it becomes preponderant for salinization of soils. The effect of proline foliar application on the growth and physiology of the green maize cultivated in salinized soil was evaluated. The experiment was conducted at the Center for Agro-Food Science and Technology (CCTA), belonging to the Federal University of Campina Grande (UFCG), Pombal, PB, from March to April 2015, using maize variety AG 1051. The treatments consisted of two levels of soil salinity (3.26 and 0.86 dS/m) and five concentrations of proline (0, 2.5, 5.0, 7.5 and 10 mmol L -¹) applied by leaf on corn plants. The experimental design was completely randomized, in the 2 x 5 factorial scheme, with four replications. A higher growth and mass accumulation was observed when the plants were conducted in soil of lower salinity (CE = 0.86 dS/m). Transpiration was influenced by salinity and proline concentration. The highest rate of intercellular CO2 concentration (Ci) was obtained at the concentration of 7.5 mmol L-¹ proline. Proline concentrations did not influence the growth and mass accumulation aspects of maize. [ABSTRACT FROM AUTHOR]

Introduction: Rhodoliths are biogenic structures distributed worldwide, formed by several types of calcareous algae. They may host a great diversity of marine invertebrates, among which polychaetes are conspicuous and diversified representatives. Rhodolith beds are notwithstanding vulnerable to several human activities (e.g. exploitation of commercial species associated with rhodoliths, petroleum exploration, fishing activities, effluent discharges, and tourism), which may compromise that diversity. Tourism is presently increasing its impact on rhodolith beds. Global warming and ocean acidification are also determinant factors in faunal change. Objective: to analyse the polychaete assemblages associated with rhodolith beds subject to different intensities of touristic pressure at Seixas Beach (NE Brazil), where tourism is gradually increasing over time. Methods: Effects were evaluated at two depths, 1.5 m and 4.0 m. Sampling was done every two months during 2015, encompassing the two marked seasons of the year in the region (rainy and dry). Quadrats of 15 x 15 cm were placed in each depth during sampling. All rhodoliths present within the quadrat were collected (usually four to five rhodoliths). Our hypothesis was that the deeper depth and the samples from the dry season months would be increasingly subject to the impact of tourism. Results: Overall, 49 species were found (from 21 different families), and a total of 733 individuals were collected. The most abundant species was Eunice wasinensis (280 individuals, 38.2% of total abundance). The species Eurythoe complanata, Eunice biannulata, E. wasinensis, Lysidice ninetta, Oxydromus pugettensis and Ceratonereis (Ceratonereis) singularis appeared in all months. The study detected a tendency for higher diversity to occur at the depth of 1.5 m for all indices, but only the Shannon-Wiener values were significantly higher there (p < 0.05). No clear differences were found regarding months or season. Conclusions: These results suggest that a higher potential pressure due to tourism may occur at 4.0 m due to more intense craft shipping activities (traffic of catamaran boats transporting tourists to and from the reefs) in that area.

Water scarcity is a one great problem faced by families residing in the northeastern semi-arid interfering directly in the his quality of life. In this context it's necessary to adopt techniques that constitute a viable alternative to improve the coexistence of families with water scarcity. Among these alternatives, the use of cisterns to capture rainwater, is gaining prominence. In this respect, the present study aimed to evaluate the use of cisterns by families in the rural land settlement Novo Horizonte in Várzea - PB. The survey was conducted in the land settlement Novo Horizonte, belonging to the municipality of the Várzea- PB, where they carried out 15 questionnaires to families living in the place. Questionnaires are of a quantitative nature, since they were translated into numbers, opinions and information to classify them and analyze them. In view of the reports of respondents noted that 100% had a cistern in his house and that they are an efficient alternative to meet the needs of the assisted families and is considered an efficient source in catchment of the rainwater and thus providing improvements in conditions and quality of life thereof.
