Effect of Foliar Application of Nutrients on Yield and Nutrient Uptake by Rice Crop

A field experiment was conducted during 2018 and 2019 at the Agronomy Research farm of A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya, UP to evaluate the effect of foliar application of macro and micronutrients on yield and nutrient uptake of rice (Oryza sativa L.). The experiment consists of 10 treatment combinations with some foliar application macro and micronutrients two foliar spray tillering stages and a panicle initiation stage which were laid out in randomized block design with three replications. The results revealed maximum grain yield (38.50 and 40.40 q ha-1), straw (51.90 and 54.60 q ha-1), and harvest index (42.64 and 42.53 %) with treatment T10-75% RDF + WSCF @ 0.5 % (19:19:19) + ZnSO4 @ 0.5 % + Boron @ 0.25 % which was statistically at par with T3- 125 % RDF and significantly superior over rest of the treatments during both the years ., was recorded Similarly significant improvement in nutrient uptake (N, P, K, S, Zn, and B) by rice was observed in T10. Thus, it can be concluded that the application of 75% RDF + WSCF @ 0.5 % (19:19:19) + ZnSO4 @ 0.5 % + Boron @ 0.25 % can improve the yield and nutrient uptake.
