Effect of different levels of NPK and vermicompost on maize [Zea mays (L.)]: An economic analysis

Abstract

The field experiment was carried out at soil science research farm of Sam Higginbottom institute of Agriculture, Technology and Sciences (deemed- to- be university) Allahabad, during Kharif season 2015-16. The design applied was 3x3 factorial randomized block design having three factors with three levels of NPK @ 0%, 50%, and 100 % ha-1, three levels of Vermicompost @ 0% &, 50% and 100% ha-1 respectively. The maximum total cost of cultivation (₹ 38784.04 ha-1) and the maximum net return (₹ 41, 64196 ha-1) was computed in T8 (N:P:K 120:60:60 kg ha-1 +Vermicompost 10 t ha-1) while the maximum net return ₹ invested (1:2.55) was recorded in T6 ( N:P:K 120:60:60 + Vermicompost 0 % t ha-1). There should be a chance of better yield and net income, suggested all operations will be performing time for this crop, because time is very important factor and play great role for greater yield and its quality, before time or after time any operations in the field of agriculture production and quality will goes down. It was found to be significant among other treatments in maize cultivation and soil quality improvement. It was also revealed that the application of NPK with Vermicompost were excellent source for fertilization than fertilizers.
