Effect of foliar application of zinc and boron on growth and yield of sweet corn (Zea mays L. Saccharata)

Abstract

A field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Kharif, 2023. The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), organic carbon (0.75%), available N (269.96 kg/ha), available P (33.10 kg/ha), and available K (336 kg/ha). The experiment was laid out in Randomized Block Design with 10 hybrids each replicated thrice. Based on the objectives taken significantly higher plant height (121.44 cm), cob length (23.28 cm), number of rows/cob (18.69) and Harvest Index (40.41%) were recorded in 0.3% zinc + boron 0.3%. Minimum days to tasseling and silking were observed in 0.2% zinc + boron 0.3% recording 62.33 and 70.33 DAS.
