Abstract:
The present study entitled, “Influence of Urea (ordinary) and Neem Coated Urea (NCU) on Performance of Rice." Involved field experiment conducted during Kharif season of year 2015 followed by laboratory analysis of the plant and soil samples in the department of agriculture chemistry and soil science, Udai Pratap Autonomous college, Varanasi (U. P). Treatment of this investigation were consisted of neem (Azadirachta indica) coated urea vis-a vis ordinary urea applied to rice variety Kashturi on the basis of soil test., its involved treatment T₁ =Control, T₂ =Farmer practice, T₃=Farmer practice up to R.D of N by ordinary urea, T₄=Farmer practice up to R.D of N by Neem coated urea, T₅=150% N of R.D by ordinary urea and T₆ = 150% N of R.D by N.C.U Neem coated. The experiment was laid out in a randomized block design (RBD) with three replications. Maximum plant height (l22.00 cm), higher number of tillers (61.67 m row length), dry matter at o0 DAT (72.20 g m^-1 row length), grain yield (62.38 Q ha^-1) and straw yield (69.80Qha^-1) of rice were obtained with T6, treatment followed by T₄>T₅>T₃ >T₂ and T₁, (control). Among various treatments the nutrients (N, P, K and S) uptake by rice plant was recorded highest fewer than 150 N of R.D by Neem coated urea (T₆) treated plots and lowers under control (T₁). Application of 150% N of R.D by Neem coated urea not only produced higher yield of rice, but also enhance soil fertility as compared uncoated urea. Higher nutrient availability was recorded in case of neem coated urea over uncoated urea.
