Effect of Production Factors on Growth and Yield of Rabi Sorghum (Sorghum bicolor L.)

An experiment was carried out at Agricultural Research Station, Tandur, Professor Jayashankar Telangana State Agricultural University (PJTSAU) for three consecutive years viz. 2014-16, 2015-16 and 2016-17 to study the Effect of production factors on growth and yield of rabi sorghum (Sorghum bicolor L.)  during the winter seasons. The experiment was laid out in randomized block design with nine treatments comprised of T1: Control only improved hybrid CSH-15-R T2: Full package of practices (FPP) T3: FPP without Irrigation T4: FPP without Fertilizer T5:FPP without Weed Control T6: FPP without -Plant protection T7: FPP without seed treatment with PSB and azospirillum T8 : FPP without Thinning T9 : FPP without Improved variety (only local variety) with three replications. The pooled results of the trial indicated that there was 32% yield reduction when the improved sorghum hybrid was grown without using all the full package of practices. (i.e., over FPP). The gross returns of rupees 115615 ha-1, net returns of rupees 91655 ha-1 and benefit cost ratio of 3.83 were recorded highest with all the full package of practices. The control is recommended to be the local variety). This is the All India Coordinated research network project conducted across India without any changes in the hybrid and is predominantly successful production factor over the variety which is released for its performance over the existing suitable varieties for testing.
