Influenced Quality of Wheat (Triticum aestivum L.) and Abate the Environmental Pollution by Soil Applied with Foliar Fertilization of NPK Fertilizer in Saline Soil

Abstract

A field experiment to assess different levels and methods of NPK fertilizer application on wheat crop was conducted on loamy sand soil at Instructional farm, College of Agriculture, Bikaner during rabi season of 2019-2020. The trial was laid out in split plot design and replicated three times. A total of 20 treatment combinations comprises A. Main plot : four RDF levels prior to sowing viz., F0 = Absolute control, F1= 50% RDF, F2= 75 % RDF and F2= 100 % RDF and B. Sub plot : five foliar fertilization levels of soluble NPK (1%) namely S0= no fertilization (control), S1= two spray (At 45and 60 DAS), S2= three foliar spray (At 45, 60 and 75 DAS), S3= four foliar spray (At 45, 60, 75 and 90 DAS). Basal application of 100% RDF with three foliar spray of soluble NPK (19:19:19) at 45, 60 and 75 DAS gave significantly higher average grain and straw yield and N, P, K content and uptake in grain and straw than other treatments, including control.
