Abstract:
A Field experiment was conducted during Kharif season 2021, at Crop Research Farm, Department of Agronomy, SHUATS Prayagraj (U.P.) on sandy loam soil with neutral soil reaction to evaluate the effect of gypsum and boron on growth and yield of groundnut. The treatments Consists of three levels of Gypsum at 200 kg/ha, 300 kg/ha, 400 kg/ha, and three levels of boron viz., 5 kg/ha, 10 kg/ha, 15 kg/ha as a soil application, whose effect was observed on groundnut. The experiment was laid out in Randomized Block Design. There were nine treatments each replicated thrice. From the results, it was observed that the growth parameters viz., plant height (64.67 cm), dry weight (42.29 g/plant), number of nodules per plant (38.71), crop growth rate (12.18g/m²/day) were recorded highest in the treatment 8 with the application of 400 kg/ha gypsum + boron 10 kg/ha. Whereas, relative growth rate (0.0150 g/g/day) recorded maximum with application of 400 kg/ha gypsum and 5 kg/ha boron. The yield parameters and yield viz., No. of pods per plant (31.36), shelling percentage (71.65%), Seed yield (2674.17 kg/ha), Haulm yield (3345.13 kg/ha), harvest index (44.43%) were also recorded highest with the treatment of gypsum at 400 kg/ha and boron 10 kg/ha.
