Effect of customized fertilizers on tlie performance of Potato (Solanum tuberosum L.)

摘要

A field experiment was conducted during Rabi season of 2010-11 at Agronomy Research Farm, Narendra Deva University of Agriculture & Technology (Narendra Nagar), Kumarganj, Faizabad. The treatments are 6 customized fertilizers having nutrients i.e. N,P,K,Zn,B, and S. Results of the study indicated that Initial and final plant stand were non-significant under various customized fertilizer. The growth characters viz. plant height, number of leaves, number of haulms, fresh and dry weight of haulms was recorded significantly higher imder customize fertilizer (F_4, which was statistically at par with F_6 and superior over rest of customized fertilizers. Yield attributes viz. total number, weight (grade wise), total weight of tubers hilL~(-1), plot ' and ha~(-1) were recorded significantly higher under customized fertilizer F_4 which was statistically at par with F^ and superior over rest of the customized fertilizers. Quality parameters viz. specific gravity, dry matter and starch content did not influenced significantly due to effect of customized fertilizers. The suitable customized fertilizer for potato crop was found to be F_4-8 ; 18 : 26 ; 1 : 0.1: 6 (N:P;K:Zn:B:S kg ha~(-1) 150 : 67.5 : 97.5 : 3.75 : 0.37 ; 22.5).
