Abstract:
A field experiment was conducted at Agricultural Research Station, Kota, Rajasthan, during rabi season of 2021-2022 to assess the effect of nutrient management on growth and productivity of wheat (Triticum aestivum L.) under rice-based cropping system. The treatment consisted of eight nutrient levels and combinations viz., 100% RDF, RDF + FYM, 125% RDF, 150% RDF, RDF + Zn, RDF + S, RDF + Zn + S and RDF + Foliar sprays of NPK. Application of 150% RDF registered the maximum growth parameters viz., number of tillers/mrl, DMA, CGR & plant height at different growth stages and grain, straw & biological yields, however, 125% RDF, RDF+FYM and RDF + Zn + S treatments found at par with it. Further, applications of RDF + Zn + S, RDF + Zn and RDF + S as well as RDF + foliar sprays of NPK 19:19:19 also enhanced the growth and productivity of wheat as compared to 100% RDF. Maximum net return was obtained under 150% RDF (₹ 106464/ha), however, 125% RDF (₹ 103460/ha) and RDF+FYM (₹ 99907/ha) as well as RDF + Zn + S (₹ 99155/ha) were found at par with 150% RDF. Application of 125% RDF provided maximum B: C ratio (3.27), which was found significantly superior over the application 100% RDF, RDF+FYM, RDF+S, RDF + Zn + S and RDF + foliar sprays of NPK.
