Effect of nitrogen levels on yield of rice varieties during kharif in South Odisha

Abstract

A field experiment was conducted at Experimental Farm of M. S. Swaminathan School of Agriculture, Paralakhemundi during kharif season of 2021 in south Odisha to study the effect of different nitrogen levels on the rice varieties. The experiment was laid out in a split plot design with three rice varieties, namely MTU 7029 (Swarna), BPT 5204 (Samba Mahsuri) and BPT 3291 (Sona Mahsuri) in main plots and four levels of N (0, 50,100 and 150 kg N/ha) in sub plots. The plant height and dry matter, yield attributes and grain yield were significantly higher in variety MTU 7029 (Swarna) over BPT 5204 and BPT 3291 (Sona Mahsuri). Application of 100 kg N/ha recorded significantly higher yield over 0, 50 and 150 kg N/ha. Application of 100 kg N/ha to variety BPT 5204 was found suitable for getting higher yield in southern Odisha in kharif season.
