Effect of tillage and organic residues on yield of wheat (Triticum aestivum L.)

摘要

A field experiment with wheat was conducted during the years 2014-15 and 2015-16 to find out the effects of different organic inputs on yield of wheat (cv. K-1006) under the conventional tillage (CT) and zero tillage (ZT) operations. The nutrients (N : P: K@ 100 : 60 : 40 in kg/ha) along with the paddy straw [@ 5 and 10 t/ha] and farm yard manure (FYM) [@ 5 and 10 t/ha], respectively, were applied with nine treatment combinations in three fold replications to raise the crop by adopting randomized blockdesign (RBD). The average grain yield (59.02 q/ha) and straw yield (73.28 q/ha) under CT at the treatment T_9 and the average grain yield (61.52 q/ha) and straw yield (76.08 q/ha) under ZT at T_9 were observed at the treatment where full dose of paddy straw and FYM along with N : P : K were applied. The yield difference of wheat over the control (N : P : K only) was observed relative to the application of organic and inorganic inputs under both the tillage operations (i. e. ZT and CT). The significantdifference on uptake of N-P-K of wheat at flowering and harvest was observed irrespective of the tillage practices (i. e. ZT and CT).
