| dc.description.abstract | A field experiment was conducted to study the effect of varied levels of phosphorus and zinc on growth and yield of aerobic rice (Oryza sativa L.)” (Cultivar rasi) during Kharif 2011 at ZARS, V. C. Farm, Mandya. Soil of the experimental site was medium in phosphorus and sufficient in zinc content. The experiment consisted of 3 levels of phosphorus (25, 50 and 75 kg ha-1) and 4 levels of zinc sulfate (0, 10, 20 and 30 kg ha-1) (12 treatments) laid out in Randomized Complete Block Design with three replications. Significantly higher grain and straw yield (3024 and 4027 kg ha-1, respectively) was recorded due to application of P at 75 kg ha-1 compared to application of P at 25 kg ha-1. But it was statistically on par with grain (2996 kg ha-1) and straw (3841 kg ha-1) yield obtained with 50 kg ha-1 P level. However, the effect of levels of zinc sulfate and interaction on yield was not significant. The uptake of P and K by aerobic rice increased significantly with increasing level of P application. Similarly, N, P, K uptake by straw varied significantly due to different levels of zinc sulfate. The interaction effect was also significant with regard to P and K uptake by straw. Higher B:C ratio was recorded due to application of P and ZnSO4 at 50 and 10 kg ha-1, respectively. | en_US |
