Effect of Phosphorus and Boron on Growth, Yield and Economics of Sweet Corn (Zea mays L.)

Abstract

A research trail was conducted in Kharif 2022, at crop research form, SHUATS, Prayagraj. To Study the “Effect of Phosphorus and Boron on growth, yield and economics of Sweet Corn (Zea mays L.)”. The treatments consisted of 3 Levels of Phosphorus (50kg/ha,100kg/ha, 150kg/ha) and Boron (200g/ha, 300g/ha, 400g/ha). The experiment was laid out in Randomized Block Design with ten treatments each replicated thrice. Application of Phosphorus 150kg/ha and Boron 400g/h produced higher Plant height(196.33cm),dry weight/plant(70.97g), maximum number of cobs per plant (1.93), cob length (20.27cm), Number of grain rows per cobs (26.65), Cob yield (6.5t/ha), Stover yield (12.23t/ha), Seed index (21.51), Harvest index (34.75), Maximum gross return (256150INR/ha), net return (198768.98INR/ha), and benefit cost ratio (3.46) when compared to the other treatment.
