Description The present experiment entitled Contribution of different production factors on the
productivity of pearl millet was conducted at Research Farm of the Department of Agronomy, CCS
Haryana Agricultural University, Hisar during kharif season of 2011-12 with the objective to study
contribution of different production factors on the productivity of pearl millet. Eight different
treatments were taken for the experiment study: T1(FPP), T2: T1-RDF (N and P), T3: T1- ZnSO4 @ 25
kg ha-1, T4: T1- Biomix, T5: T1- Thinning and gap filling (19 DAS), T6: T1- Weeding and hoeing (20
and 35 DAS), T7: T1- Irrigation, T8: Control in randomized block design with three replications.
Phenological events viz. emergence, three leaf stage, five leaf stage, flag leaf stage, boot stage,
50 % flowering, milk stage, dough stage, physiological maturity were not significantly affected by
different treatments .Growth parameters i.e. plant height (cm), total number of tillers plant-1, dry matter
accumulation (g plant-1), leaf area plant-1 (cm2), leaf area index , yield attributing characters [number of
effective earheads plant1, earhead length (cm) and test weight (g) ], grain and stover yield (kg ha-1)
differ significantly among various treatments.
Non adoption of individual factors i.e. RDF (T2), ZnSO4 (T3), biomix (T4), thinning and gap
filling (T5), weeding and hoeing (T6) and irrigation (T7) cause a decrease in grain yield by 32.8, 12.2,
7.7, 16.7, 30.1, 20.2, 48.0 (control) 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. Among all the treatments T1 recorded significantly higher N, P
and K content and their uptake in grain and stover and protein content in grain and its yield. Maximum
gross returns (Rs. 48727 ha-1), net returns (Rs. 16926 ha-1) and B: C ratio (1.53) were found in
treatment T1 followed by T4.
