Abstract

During the kharif season of 2016, a field experiment was carried out at the farm of the Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Wadura, to investigate the "influence of nutrient management practices on yield and economics of maize under rainfed conditions". The experimental field's soil was sandy loam in texture, neutral in response (PH= 6.7), with medium nitrogen (240 kg/ha), P2O5 (23.2 kg/ha), and K2O (156.80 kg/ha). The experiment was set out in an RCBD design with nine treatments and three replications. Grain yield (70.50 q/ha), stover yield (124.22 q/ha), and yield attributes were higher with RDF (90N + 45 P2O5 + 20 K2O + 10 ZnSO4) kg/ha+ seed inoculation with PSB and KSB (T6) compared with other treatments except for the 90% RDF of P2O5 and K2O + seed inoculation with PSB and KSB (T6) (T9). RDF + seed inoculation with PSB and KSB (T6) yielded 7.9% higher grain yield and 8.0% higher stover yield than RDF (90N, 45P2O5, 20K2O, 10ZnSO4) kg/ha. B:C ratio was also higher when RDF+ seed inoculation with PSB and KSB was used (3.85), followed by 90% (P2O5 and K2O) of RDF+ seed inoculation with PSB + KSB (3.74), RDF (90N, 45 P2O5, 20 K2O, 10ZnSO4) kg/ha (3.61), 80% (P2O5 and K2O) of RDF + seed inoculation with PSB (3.48), 70 % (P2O5 and K2O) of RDF+ seed inoculation with PSB + KSB (3.31), P- omission (2.89), K-omission (2.85), seed inoculation with PSB + KSB (2.41), control (2.33)

Keywords

Yield, economics, nutrient management, PSB, KSB.

Conclusion

Investigations on “Influence of nutrient management practices on yield and economics of maize (Zea mays L.) under rainfed conditions” revealed that application of RDF (90 N, 45 P2O5, 20 K2O, 10 ZnSO4) kg/ha+ seed inoculation with PSB + KSB recorded significantly high grain yield, stover yield and net returns of Rs 82,891 and benefit cost ratio of Rs 3.85. In view of this, it may be concluded that for obtaining maximum economic grain and stover yield in maize, it needs to be fertilized with RDF (90 N, 45 P2O5, 20 K2O, 10 ZnSO4) kg/ha + seed inoculation with PSB + KSB.
