Significance of Integrated Nutrient Management Practices on Growth and Yield Certain Traditional Rice Varieties

Abstract

Background and Objective: Being a modern food habit world, the global population tries to take back their health by way of consuming traditional rice varieties which possess a lot of nutritional assets, traits of disease and pest resistance and certain specific traits of tolerance to stress conditions. But the area of its cultivation is quite less due to its low yielding potential. Developing an ideal nutrient schedule using inorganic and organic sources helps to improve their productivity and to evaluate the significance of INM practices on the growth and yield of traditional rice varieties this study was conducted. Materials and Methods: The experiment was conducted during the Navarai season in 2018 at an experimental farm, Faculty of Agriculture, Annamalai University, India. The experiment was laid on a split-plot design with four traditional varieties in main plots four INM practices and control in the subplots. Results: It was found that the traditional rice variety Karungkuruvai proved its superiority in growth and yield attributes and yield over other tested varieties. Application of 125% RDF+Sesbania aculeata at 6.25 t haG 1 +bio-fertilizer registered the maximum values of growth attributes except for yield which was realized with 100% RDF+Sesbania aculeata at 6.25 t haG 1 +bio-fertilizer combination in all the traditional rice varieties. Conclusion: The study identified that the INM practice of applying 100% RDF+Sesbania aculeata at 6.25 t haG 1 +bio-fertilizer can be beneficial for increasing the yield of traditional rice varieties significantly.
