Abstract:
Studies on effect of different planting time (July, July-August and August) and nitrogen management of 100% RDN and 150% RDN with 2 different splits (1/2+1/4+1/4 and or 1/3+1/3+1/3) on the growth, yield and quality of high protein rice, was conducted during wet season of 2017 and 2018 at the research farm, National Rice Research Institute, Cuttack, Odisha.
The crop transplanted on August (late planting) was recorded significantly higher root length and root volume at 60 DAT, 90 DAT and at harvest during 2017, 2018 and in pooled data. Significantly higher grain yield was recorded with late planting (August) during 2017, 2018 and in pooled data followed by normal planting (July-August) during 2017 and in pooled data, and early planting (July) during 2018. Crop fertilized with 150% RDN in 3 splits (1/2+1/4+1/4) was recorded higher root length, root volume at 30, 60, 90 DAT and at harvest during both years and in pooled data, however, it was at par with 150% RDN in 3 splits (1/3+1/3+1/3). Minimum root length, root volume was recorded under control (No nitrogen) at 30, 60, 90 DAT and at harvest during 2017, 2018 and in pooled data. Significantly higher grain yield and ASV was recorded with application of 150% RDN in 3 splits (1/2+1/4+1/4) and lower was recorded with control (No nitrogen) during 2017, 2018 and in pooled data.
