Abstract:
A field study was carried out at Agronomy research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi season 2018-19 and 2019-20 to evaluate the effect of different crop establishment methods with or without residue and fertility levels on yield and economics of late sown wheat (Triticum aestivum L.) after rice crop. The Experiment consist of five Crop establishment methods (CT_B, CT₀, CT₁, ZT₀, ZT₁) and four Fertility levels (F₁, F₂, F₃, F₄) in 20 treatment combination viz. CT_BF₁, CT_BF₂, CT_BF₃, CT_BF₄, CT₀F₁, CT₀F₂, CT₀F₃, CT₀F₄, ZT₀F₁, ZT₀F₂, ZT₀F₃, ZT₀F₄, ZT₁F₁, ZT₁F₂, ZT₁F₃, ZT₁F₄. The result revealed that in case of Crop establishment methods maximum grain, straw and biological yield was recorded with ZT₁ (Zero tillage with residue) which is at par with CT₁ (Conventional tillage with residue). Regarding fertility levels, maximum grain, straw and biological yield was recorded with F₄ (100% RDF-IF + 10 t ha^-1 FYM) which is at par with F₃ (100% RDF-IF + 5 t ha^-1 FYM) and F₂ (125% RDF-IF). Among all different treatment combinations, ZT₁F₄ treatment recorded maximum grain, straw, biological yield and gave maximum value of gross return. But best net returns and benefit cost ratio was observed in ZT₁F₃ which is closely followed by ZT₁F₂.
