M aize (Zea mays L.) is a cereal crop grown in almost all countries of the world. It has largely used as a staple food in Pakistan as well as other developing countries of the world. In Khyber Pakhtunkhwa, it is the 2 nd most important and grown crop after wheat (Triticum aestivum L.), whereas in Pakistan its rank is 3 rd . Maize crop has multiple uses like it is used as food, feed and raw materials for commercial product preparation (Khan et al., 2017). Pakistan economic survey show that maize was planted on 1.40 million ha land and produced 7.88 million tons with 5121 kg ha -1 average yield (MNSF&R, 2020). In Pakistan, maize production is lower than world leading countries due to less fertility of soil, improper usage and time of fertilizer application and several other agronomic management problems.

Micronutrient deficiency is widespread in alkaline soils of Pakistan which ultimately affect the yield and quality of sunflower oil. The current study was designed to investigate the combined as well as the sole effect of micronutrient application on the growth and yield attributes, and fatty acids profiling of selected sunflower hybrids. A field trial was conducted in sub-humid climatic conditions and two sunflower hybrids (FMC-1 and Parsun-3) were grown at the University of Haripur’s research farm. Micronutrients were applied through the foliar application at the start of the bud growing stage and before the flowering stage i.e., after 30 and 55 days of sowing. The application of micronutrients resulted in significant variation in agronomic parameters of sunflower hybrids. Molybdenum among the sole application and in combination treatments Zn, B, and Mo increased the growth traits of sunflower genotypes, while application of Zn and Mo (among sole application), and combination of Zn, B, and Mo increased the yield attributes. Oil content was highest in the combination of three micronutrients (Zn, B, and Mo) application followed by the Zn and B application individually. Sole micronutrients application also increased oil contents in both hybrids. Zinc application resulted in an increase of unsaturated fatty acids and a decrease in saturated fatty acids, while the B increased the oleic acid and stearic acid content and decreased the linoleic acid and palmitic acid contents. Among the varieties, FMC-1 has significantly achieved a higher yield than the Parsun-3. It is concluded from the research that Zn application increased the beneficial (poly- and mono-unsaturated) fatty acids and decreased the harmful (saturated) fatty acids. Zinc application @ 2 kg ha1 is recommended for good quality oil production.

Soil health Index demands organic fertilizer usage may be imperative couple with chemical fertilizers. Mungbean (Vigna radiata) yield and nutrients content were studied during kharif 2019 through coal and plant based humic acid (HA) application at NARC. The plots were arranged in randomized complete block design (RCBD). Results indicated that application of HA couple with chemical fertilizers significantly improved mungbean yield and nutrients content. HA at 15 kg ha -1 along with 50 kg ha -1 DAP recorded the highest grain yield (0.79 t ha -1 ) that is 14.4% more than the control (0.69 t ha -1 ) receiving 100% DAP application alone. The highest concentration of P (0.34 %), K (3.7%) and N (3.65%) in whole shoot mungbean were observed in the treatment where HA was applied at 15kg ha -1 along with 50 kg ha -1 DAP. Residual organic matter improved by 0.06%. Based on findings of this study it can be suggested that HA couple with inorganic fertilizer application have significant effect on grain yield and nutrients content of N and P. It showed that HA mayenhanced NO 3 and P availability through chelation and reduce soil P fixation.
