Influence of Zinc and Boron on Yield and Economics of Cowpea

“A field experiment was conducted at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, UP, during the autumn season of 2022 on sandy loam soil. The experiment was carried out in Randomized Block Design supplemented by Zinc (10, 15, 20 kg/ha) and Boron (1, 1.5, 2 kg/ha)”. The variety Kashi Nidhi was used and sown in July 2022. The results revealed that the crop supplemented with 20 kg/ha Zinc + 2 kg/ha boron increased significantly in yield parameters viz., no. of pods per plant (19.7), no. of seeds per pod (15.6), seed yield (1.28 t/ha) and stover yield (2.43 t/ha). This treatment also showed a positive effect on economics viz., gross returns (84029.00 INR/ha), net returns (56369.00 INR/ha) and B: C (1:2.03).

Influence of Sulphur and Foliar Spray of Iron on Growth and Economics of Maize

A field experiment was conducted at Crop Research Farm, Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Prayagraj, UP, during the Zaid season of 2022 on sandy loam soil. The experiment was laid out in Randomized Block Design, consisting of three levels of sulphur (10 kg/ha, 15 kg/ha, 25 kg/ha) and three levels of iron as a foliar spray (1500, 2000, 2500 mg/kg). The maize variety Kanchan was sown in April 2022. The results of the experiment revealed that the application of 25 kg/ha of sulphur along with 2500 mg/kg of iron significantly increased the growth parameters viz., plant height (196.4 cm), and dry weight (83.03 g/plant), whereas, application of 25 kg/ha of sulphur and iron at 2500 mg/kg also showed a positive effect on economics viz., gross returns (121644.00 INR/ha), net returns (84843.00 INR/ha) and B: C (1:2.30).
