Effect of foliar application of micronutrients on growth, yield and nutrient uptake of maize
Abstract
A field experiment was conducted at Agricultural Research Station Madhurakhandi, to study the effect of foliar application of micronutrients on growth, yield and nutrient uptake of maize (Zea mays L.) during kharif 2014. Results revealed that soil application of recommended dose of N, P2O5, K2O along with foliar application of ZnSO4 @ 1.0 per cent during grand growth stage recorded significantly higher plant height (205.20 cm), stem diameter (29.70 mm), leaf area (93.28 dm2) and dry matter production per plant (409.95 g). The grain yield also was significantly higher with soil application of recommended dose of N, P2O5, K2O along with foliar application of ZnSO4 @ 1.0 per cent during grand growth stage (89.73 q ha-1), due to improvement in yield attributing characters like cob length, cob girth, number of grains per row, total number of grains per cob, grain weight per cob and 100 grain weight. Higher Zinc, Iron and Boron content in leaf was also observed in foliar application of micronutrient compare to soil application. In the present study, soil application of recommended dose of N, P2O5, K2O along with foliar spray of ZnSO4 @ 1.0 per cent followed by soil application of N, P2O5, K2O along with foliar spray of ZnSO4 + FeSO4 @ 0.5 per cent each during grand growth stage recorded increased growth and yield of maize
