Abstract:
In Tripura rice is grown in 2.75 lakh ha of area with a production and productivity of 8.21 lakh tones and 2.9 t ha-1. High yielding rice variety is gown in most of the area of Sepahijala district but the varieties grown by the farmers either very old or susceptible to various pests and diseases due to that the production from those varieties are less as compared to the new high yielding varieties. Assessment of high yielding rice varieties for assessment of their growth and yield performance was conducted at five different farmers’ fields during the year 2019-20 under on farm testing. In the experiment individual farmers are taken as replications and high yielding rice varieties are taken as treatments. From the experiment the results revealed that Gomati recorded the highest values for growth, yield and cost economics traits. Though the growth characters like plant height (140 cm), 50% flowering (74.20 days) and total duration of varieties (138.60 days) in case of Sahalom but the highest yield recorded under variety Gomati (5.36 t ha-1) followed by Tripura Chickon (4.62 t ha-1) and Sahalom (3.98 t ha-1), where variety Gomati also resulted significantly highest test weight (23.04 g) and number of panicle (m-2) (517). In the case of benefit cost ratio, Gomati recorded the highest ratio of 1.71 with the net profit of Rs 41495.32 followed by Tripura Chickon (1.48) whereas local check (Sahalom) observed the lowest B:C ratio (1.27) and net profit of Rs. 15,938.92. Gomati is performed well and increased yield of 35% with good market preference over the farmer’s practices. Due to highest yield of Gomati was found to be the most suitable high yielding rice variety under Sepahijala district conditions.
