ABSTRACT
The experiment was conducted in rabi 2016-17 and 2017-18 on hybrid maize comprising ten treatments in nutrient and residue management practices, viz. T1 - F P (N155 P115 K45), T2 - 100% RDF (N120 P60 K40), T3 - 100% RDF [N120 P60 (25 % P2O5 at RI and 75% as basal) K40], T4 - 100% RDF (N120 P60 K40) + Trichoderma and T5 - 100% RDF [N120 P60 (25 % P2O5 at RI and 75% as basal) K40] + Trichoderma, T6 - 75% RDF (N75 P45 K30), T7 - 75% RDF [N90 P45 (25 % P2O5 at RI and 75% as basal) K30 , T8 - 75% RDF (N90 P45 K30) + Trichoderma, T9 - 75% RDF [N90 P45 (25 % P2O5 at RI and 75% as basal) K30] + Trichoderma and T10 – control. The results of maize revealed that application of T5 -100% RDF [N120 P60 (25 % P2O5 at RI and 75% as basal) K40] +Trichoderma produced the highest grain (81.3 q ha-1) and stover yield (136.1 q ha-1) and nitrogen uptake by grain (89.5 kg ha-1) and stover (131.5 kg ha-1). The highest phosphorus (33.3 and 43.8 kg ha-1) and potassium uptake (94 and 137 kg ha-1) by grain and stover, respectively was obtained under T1- F P (N155 P115 K45). The comparable performance of above parameters were also noticed under the treatments of T1 - F P (N155 P115 K45), T2 - 100% RDF (N120 P60 K40), T3 - 100% RDF [N120 P60 (25 % P2O5 at RI and 75% as basal) K40] and T4 - 100% RDF (N120 P60 K40) + Trichoderma.
