SUMMARY

The present experiment was conducted at Research Farm of the Department of Agronomy, CCS Haryana Agricultural University, Hisar during kharif  season of  2011 with the objective to quantify the contribution of different production factors on the grain productivity of pearl millet. T1 : FPP [RDF (125 kg N+62.5 kg P/ha) + ZnSO4 @ 25 kg /ha+ biofertilizer biomix (Azospirillum +PSB) + thinning and gap filling + weeding and hoeing (20 and 35 DAS) + irrigation] , T2 : T1 – RDF (N and P), T3 : T1 – ZnSO4 @ 25 kg /ha, T4 : T1­­­ – biomix, T5 : T1 – Thinning and gap filling (19 DAS), T6 : T1 – Weeding and hoeing (20 and 35 DAS), T7 : T1 – Irrigation and T8 : Control in randomized block design with three replications. Non adoption of individual factors  RDF (T2), ZnSO4 (T3), biomix (T4), thinning and gap filling (T5), weeding and hoeing (T6) and irrigation (T7) caused a decrease in grain yield by 32.8, 12.2, 7.7, 16.7, 30.1, 20.2, 48.0 (control) per cent and stover yield  by 22.7, 7.9, 4.0, 10.0, 18.9, 16.0 and 32.2 per cent (control) than T1 (FPP),  respectively.  Maximum gross returns (Rs. 48727/ha), net returns (Rs. 16926/ha) and B : C ratio (1.53) were found in treatment T1 followed by T4.
