Effect of slow release coated urea on growth, yield and economics of wheat (Triticum aestivum) under subtropical conditions of Jammu

An experiment was conducted under assured irrigated conditions of humid eco-region of Western Himalayas to study the effect of slow release coated urea on growth, yield and economics of wheat under subtropical conditions of Jammu. The experimental results revealed that application of 100% of Rec. N through ZnCU + Rec. P, K & Zn recorded significantly better growth measured in terms of plant height and dry matter production, yield attributing characters and grain and straw yield, during study and found at par with application of 85% of Rec. N through ZnCU+ Rec. P, K & Zn, 100% of Rec. N through NCU + ZnCU+ Rec. P, K & Zn, 85% of Rec. N through NCU + ZnCU+ Rec. P, K & Zn and 100% of Rec. N through NCU + Rec. P, K & Zn. However with regard to economics application of 100 % of Rec. N through ZnCU+ Rec. P, K & Zn, recorded highest gross return, net returns and B:C ratio to the tune of 109005, 79018 and 2.64 respectively which was closely followed by 85% of Rec. N through ZnCU + Rec. P, K & Zn to the tune of 106341, 76580 and 2.57 respectively.
