Effect of different nitrogen levels on yield and qualities of red rice cultivars

Abstract

The experiment was carried out at Instructional cum Research Farm, IGKV, Raipur (C.G.) during Kharif season, 2018 to study the different nitrogen levels on qualities of red rice cultivars. The experiment consisted five red rice cultivars (Bantha luchai, Shrikamal, Kankadiya, Khuddi and Jyothi) in main plot and four nitrogen levels (0, 60 kg N ha-1, 80 kg N ha-1 and 25 kg N ha-1 + LCC based nitrogen management) in sub plot laid out in split plot design with three replications. Maximum grain yield (4.5 t ha-1) was recorded with variety Jyothi fertilized with 80 kg N ha-1. Maximum value for kernel length and breadth before and after cooking was also recorded by variety Jyothi. However Length/Breadth ratio was not influenced significantly by different levels of nitrogen. Hulling per cent, milling per cent and head rice recovery per cent was obtained higher with application of 80 kg N ha-1. Variety Jyothi showed higher alkali value and it was not influenced by different nitrogen levels.
