Effect of silicon and boron on growth and yield of sweet corn

Field experiment titled “Effect of Silicon and boron on growth and yield of sweet corn” was conducted during kharif 2023 at Crop Research Farm. Department of Agronomy, Naini Agriculture Institute SHUATS, Prayagraj Uttar Pradesh. The chemical analysis of soil at pre experiment stage are nitrogen (188.3 kg/ha), Phosphorus (34.5 kg/ha), potassium (87 kg/ha), with pH (7.4). The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice. The treatments combination are T₁: Silicon 100 kg/ha + boron 0.50 kg/ha, T₂: Silicon 100 kg/ha + boron 1.0 kg/ha, T₃: Silicon 100 kg/ha + boron 1.50 kg/ha, T₄: Silicon 140 kg/ha + boron 0.50 kg/ha, T₅: Silicon 140 kg/ha + boron 1.0 kg/ha, T₆: Silicon 140 kg/ha + boron 1.50 kg/ha, T₇: Silicon 180 kg/ha + boron 0.50 kg/ha, T₈: Silicon 180 kg/ha + boron 1.0 kg/ha, T₉: Silicon 100 kg/ha + boron 1.50 kg/ha, T₁₀: Control – 120:60:60 (N:P:K) Kg/ha are used. Results obtained that combined the application of Silicon 100 kg/ha + boron 1.50 kg/ha was recorded significantly higher growth of crop which was recorded with the study of crop growth parameters such as plant height (158.2 cm), plant dry weight (62.12 g/plant) and yield attributes like effective cobs per plant (1.9), number of grains row per cob (16.5), number of grain per rows (24.7), number of grains per cob (374.5).
