Abstract:
The field experiment was conducted at Research Farm, Department of Agronomy, JNKVV, College of Agriculture, Rewa (M.P.) during Kharif season of 2018 to study economics of transplanted rice as influenced by different varieties of rice cultivation under various nitrogen levels. The experiment was laid out in split-plot design with three replications. Three nitrogen levels (N₁, 80 kg/ha; N₂, 100 kg/ha; N₃, 120 kg/ha) and six rice cultivars (V₁ - Kalanamak, V₂ - IR-64, V₃ - Chittimuthyalu, V₄ - BPT5204, V₅-IET-26375 and V₆ - IET-26383). Among the rice cultivar the V₅ - IET-26375 performed significance superior over rest of varies at all levels of nitrogen. Results revealed that application of nitrogen @ 120 kg/ha recorded significantly higher grain yield (46.92 q/ha) as compared to N₂ (100 kg/ha) (46.42 q/ha) and N₃ (80 kg/ha) (43.46 q/ha). Rice variety V₅ - IET-26375 showed significant superiority over other varieties under all the three nitrogen levels (80, 100 and 120 kg/ha) in terms of grain yield, NMR and B: C ratio. The net monetary returns and B: C ratio were found to be the maximum (Rs. 54909 ha^-1 and 2.81, respectively) under IET-26375 variety of rice.
