Abstract
At the Department of Agronomy's Crop Research Farm, SHUATS, Prayagraj, a field experiment was carried out in the month of Zaid 2022. (U.P). The soil in the experimental plot had a sandy loam texture, a pH of 7.1 that was almost neutral, a low level of organic carbon (0.36%), and low availability of the nutrients N, P, K (171.48 kg/ha, 15.2 kg/ha, and 232.5 kg/ha, respectively). Ten treatments, each replicated three times, were used in the experiment, which was set up using a randomised block design over the course of a year. The treatments which are T1: Sugar-75 + 0.1 % boron foliar application, T2: Sugar-75 + 0.2 % boron foliar application, T3: Sugar-75 + 0.3 % boron foliar application, T4: Madhuri + 0.1 % boron foliar application, T5: Madhuri + 0.2 % boron foliar application, T6: Madhuri + 0.3 % boron foliar application, T7: Misthi + 0.1 % boron foliar application, T8: Misthi + 0.2 % boron foliar application, T9: Misthi + 0.3 % boron foliar application, T10: Control - N:P:K-120:60:40(kg/ha) are used. The results showed that treatment T9-Misthi + 0.3% boron foliar application was recorded significantly higher growth parameters like Plant height (175.5 cm), Plant dry weight (141.6 g/plant) at 80 DAS and highest Crop growth rate (22.1 g/m2/day) at 60-80 DAS. However, yield attributes and yield parameters like No. of Cobs/plant (1.81), No. of Grains/Cob (617.7), No. of Rows/cob (14.37), Seed index (68.4 g), cob length (18.5 cm), Grain yield (9.5 t/ha), Stover yield (15.4 t/ha) were recorded with the treatment T9-Misthi+ 0.3 % boron foliar application.
