Foliar Nutrition: A Novel Technology to Increase Growth and Yield in Baby Corn (Zea mays L.)
Year: 2018
Type: article
Abstract: A field experiment was conducted at Zonal Agricultural Research Station, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru during kharif 2016 to study the effect of foliar application of macro and micro nutrients on growth and yield attributes of baby corn (Zea mays L.). The experiment was laid out in a Randomised Complete Block Design with nine treatments replicated thrice. Application of 75% RDF + 1.5% 19:19:19 spray + 0.2% ZnSO4 + 0.1% FeSO4 recorded significantly higher baby corn and green fodder yield (244.05 q ha-1 and 85.16 t ha-1, respectively) and was on par with application of 75% RDF + 1.5% 19:19:19 spray + 0.5% ZnSO4 + 0.1% FeSO4 (212.37 q ha-1 and 76.82 t ha-1, respectively). This was attributed by enhanced growth parameters viz., plant height (144.91 cm), total dry matter (152.28 g plant-1), Absolute growth rate (1.79 g day-1), Crop growth rate (1.77 g-2 day-1), Net assimilation rate (5.56 g dm-2 day-1), Leaf area index (6.84), Leaf area duration (78.53 days) and yield attributes like number of cobs plant-1 (3.67), length of babies (10.90 cm), girth of babies (4.07 cm) and weight of babies (23.87 g cob-1).
