Effect of foliar application of nutrient elements on upland rice under water stress condition in Bastar Plateau

Abstract

An experiment was conducted during Kharif 2017 at SGCARS, Jagdalpur research farm in upland situation with the objectives of assessing the effect of foliar application of nutrient elements on upland rice under water stress condition in Bastar plateau. The experiment was conducted in randomized block design with twelve treatments namely T1 (RDF as control), T2 (RDF + water spray at stress condition), T3 (RDF + P spray (KH2PO4, 2%) at stress condition), T4 (RDF + P spray (KH2PO4, 1%) at stress condition), T5 (RDF + N spray (Thiourea, 2000 ppm) at stress condition), T6 (RDF + N spray (Thiourea,1000 ppm) at stress condition), T7 (RDF + B spray (borax, 0.5%) at stress condition), T8 (RDF + B spray (borax, 0.25%) at stress condition), T9 (RDF + Zn spray (ZnSO4, 0.5%) at stress condition), T10 (RDF + Zn spray (ZnSO4, 0.25%) at stress condition), T11 (RDF + KNO3 spray (1%) at stress condition) and T12 (RDF + KNO3 spray (0.5%) at stress condition). The RDF was 80:50:30 kg NPK ha-1. The stress was created for 20 days from 40 to 60 DAS and treatments were imposed at 45 and 55 DAS with 375 litres of water per hectare.
