Abstract:

Drought is the major problem in India and occurrence at the time of critical growth stages, reduce crop yield significantly. The National Rice Research Institute, Cuttak, Odisha has developed so many drought tolerance rice varieties to reduce the economic loss due to drought. Krishi Vigyan Kendra, Malkangiri introduced NRRI released two rice varieties i.e. Sahbhagi Dhan and Satyabhama at framers' field to evaluate the performance of these drought tolerant varieties in South Eastern Ghat Zone of Odisha. The highest plant height was observed with the rice variety Satyabhama (104.1 cm). But, overall performance of Sahbhagi Dhan was better as compare to Satyabhama and local check verity (Khandagiri). Sahbhagi Dhan gave highest yield of 36.5 q/ha, which was statistically differed from others. Correlations study for Sahbhagi Dhan was assessed and observed the positive correlation for grain yield with all studied characters except plant height. For economic point of view, Sahbhagi Dhan recorded highest net return of Rs.19, 925/- per ha along with B:C ratio of 1.6 as compared to the rest two varieties.
