The present study was conducted to analyse family farming in context of socio-economic needs of farmers in district Nankana Sahib, Punjab, Pakistan in 2019. Tehsil Nankana Sahib was selected purposively as it was the largest tehsil of the selected district (Nankana Sahib). Twenty union councils were selected randomly; from each of the selected union councils three farm families were selected by using snow ball sampling technique. From each of the selected families, two respondents, one head of the farm family and second any other adult family member (willing to give concerned data) were selected. In this way, a validated and reliable interview schedule was used to collect data from 360 respondents. The collected data were analyzed with Statistical Package for Social Sciences (SPSS). Mean, standard deviation, weighted score and rank order were calculated to interpret the data. It was concluded that family farming was providing food to whole family (score = 1570 and mean = 4.36). It was also playing its role to engage the whole family in farming related activities (score = 1548 and mean = 4.30). The family-based farming was also responsible for a better living standard (score = 1321 & mean = 3.67) of the family farmers, it was also the only source of income to fulfill the expenditures for happy and sad moments (score = 1310 and mean = 3.64), and the family farming was also contributing for better health and education (score = 2364 and mean = 3.79). The family farmers were also depending on farms for their agricultural needs (seed, fertilizers, pesticides and etc.). It was suggested that family farmers should move towards modern agricultural farming techniques to secure their profesion as well as themselves. [ABSTRACT FROM AUTHOR]

Nanotechnology plays a significant role in promoting agriculture and agricultural products. Agriculture and food industry aims for the sustainability and the protection of agricultural products, including crops for human and livestock. Nanotechnology helps in the manufacturing of innovative agrochemicals and novel delivery mechanisms to enhance crop production and decrease in pesticide use. Nanotechnology also contributes in increasing the crop yield in agriculture. One of the major contribution of nanotechnology in the field of agriculture is the formulation of nano based pesticides and fertilizers for increased crop production. Precise farming techniques can promote crop production without damaging soil and water, reducing losses due to leaching of nitrogen and enhancing long lasting incorporation of nutrients by micro-organisms present in the soil. Another major breakthrough of nanotechnology for improvement in agriculture production is the development of insect-resistant varieties by DNA transfer in the plants or nanoparticle-mediated gene. Biofuel production from biomass is estimated to speed up using nanotechnology. Researchers and manufacturers have to demonstrate that the application of nanotechnologies have no harmful effect on the atmosphere against the anomaly based only on small amounts of toxicological research and concerns about the safety of nanomaterials.

Sunflower (Helianthus annuus L.) is an important oil seed crop in Pakistan having the potential of bridging gap between production and consumption of edible oil in the country. The experiment was conducted at National Agriculture Research Center (NARC) Islamabad, Pakistan, during August to December, 2016, to evaluate different exotic sunflower hybrids for their performance and adaptability in the field area of NARC. Twelve sunflower hybrids including one check i.e. SF-16013, SF-16007, SF-16010, SF-16005, SF-16006, SF-16002, SF-16008, SF-16004, SF-16011, SF16003, SF-160011, Hysun-33 were studied in the experiment. The experiments were carried out in Randomized Complete Block Design with three replications. The distance between adjacent rows was 75 cm while the distance between plants to plant was 30 cm. The seed was sown in the first week of August. The following parameters were studied in the experiment i.e. days to flower initiation, days to flower completion, plant height, days to maturity, stem diameter, head diameter, number of leaves, 1000 seed weight and seed yield per hectare. Quality parameters were consisted upon oil content (%), protein content (%), and fatty acid profile. The results showed that significantly highest seed yield (2187.3) kg ha-1 was produced by SF 16003 followed by SF16010 and SF 16002 having (2016.2) kg ha-1 and (1888.2) kg ha-1 seed yield respectively. The Cluster analysis also determined SF 16003 as best hybrid which was at a very close distance from the group of SF16010 and SF 16002. [ABSTRACT FROM AUTHOR]

Wheat is the main cereal crop and a staple food in Pakistan. It is an important cereal crop of Potohar region. Weeds infestation is a major cause of low wheat yield. Synthetic herbicides are mostly used to control weeds. A field experiment was conducted to investigate the Chemical control of broad-leaved weeds in wheat at the Koont Research Farm, PMAS-Arid Agricultural University, Rawalpindi, during rabbi season, 2014. The experiment was laid out in a randomized complete block design (RCBD) with four replications, with a plot size of 06 x 04 m2. Four different herbicides were applied as post emergence with three different doses each viz:,Ally max @ 34.58, 46.11 and 23.04 g ha-1, Lihua @ 53.34, 72.4 and 36.23 g ha-1, and Wheat Star @ 370.5, 494 and 247 g ha-1 and Buctril super 60% EC @ 741, 988 and 494 ml ha-1. An untreated control and hand weeded plot was also included in the trial. Wheat variety AUR-2009 was sown as a test crop and the herbicide was applied 65 days after sowing. All herbicides were sprayed as post-emergence. The best weed control was accomplished by Wheat star@ 494 gha-1 as profoundly lower weed counts m-2 (26), and higher percent weed control (27.9%) were noted after 25 days of its spray. Wheat growth parameters like plant height, number of tillers per m2, spike length and number of spikelets per spike remained statistically at par among various treatments. Significantly higher number of fertile tillers (172), Plant height (93.83 cm), spike length (7.4 cm) were noted with Wheat Star @ 370.5 g ha-1. Although treatments did not differ significantly with respect to wheat grain and biological yields, yet the highest grain yield (3295 kg ha-1) and biological yield (11173 kg ha-1) were produced by Wheat Star @ 370.5 g ha-1. Based on better weed control and wheat yield, Wheat Star @ 370.5 g ha-1 and Buctril Super @ 741 ml ha-1 are recommended in similar areas where wheat fields are predominantly affected by drought and infested by broad leaved weeds.

Soil weed seed bank is a natural source for weed infestation. Determination of soil weed seed bank has primary importance to get complete picture of weed seed reservoir in the soil profile. An experiment was conducted at University Research Farm, Chakwal Road, Rawalpindi to compare the techniques for determination of soil weed seed bank during winter 2012-2013 under rainfed conditions of Pothowar. Soil samples for the weed seed bank analysis were taken from the experimental field before wheat sowing from 0-10 cm, 11-20 cm and 21-30 cm soil depth. Two soil weed seed bank determination techniques were compared viz., sieving method and seedling emergence method. The data were collected on the seed density m-2, seed frequency, diversity of weed species and relative importance value. The input and output data was also collected to find out the socioeconomic feasibility of the techniques. The comparative analysis of seed bank extraction methods revealed higher weed seeds density, weed frequency with more diversity of weed species under sieving method in comparison to seedling emergence method. Therefore, sieving method was considered superior over seedling emergence method. The feasibility analysis of seed bank extraction methods indicated that sieving was cost-effective, less time consuming, more user friendly with higher accuracy over seedling emergence method.
