Impact of FYM and micronutrients on nutrient content, uptake, yield and economic attributes of direct seeded basmati rice

A field experiment was carried out at CCS HAU, College of Agriculture, Kaul research farm during kharif, 2020 to study the effect of FYM and micronutrients on nutrient content, uptake, yield and economic attributes of direct seeded basmati rice. The experiment was laid out in randomized block design with 7 treatments including each with a different combination of chemical fertilizer (RDF), farmyard manure (FYM), and micronutrients (ZnSO₄ and FeSO₄). Amongst the all treatments, 75% RDF along with FYM @ 15 t/haresulted in the highest yield attributes (like plant height, number of effective tillers per m², grain yield, straw yield and harvesting index) and economic parameters (like cost ofcultivation, gross return, net return and benefit-cost ratio) which was at par with 50% RDF with FYM @ 15 t/habut statistically superior then control. Amongst micronutrient treatments, combined foliar application of zinc and iron along with RDF resulted in higher yield and highest Benefit and Cost ratio (B:C) was observed as compared to other treatments resulting in higher returns with low cost of cultivation.
