Abstract
Climate change and its consequences have severely affected Nepalese agriculture. The higher temperature in the lower elevations of the tropical region as well as lower temperature in the higher elevations has adversely affected rice cultivation. Therefore, to evaluate the performance of different rice genotypes in central hills present experiment was carried out at Nepal Agricultural Research Council, Khumaltar, Lalitpur, Nepal in 2017 A.D. under irrigated main season rice system. Split Plot design with three different heights of plastic chamber (Chamber with height of 4', 5'4" and 6'9") and one open field as a main plot factor and four different rice genotypes (Khumal 10, NR 1105 B-B- 27, Khumal 8, 08 Fan-10) as a sub plot factor were used. 25 days seedlings were transplanted in 12 m2 plot area in July 1, 2017 at 20×20 cm spacing. The result showed that the temperature increments inside the chamber have not significantly influenced the yield of rice. Within 4 rice genotypes, Khumal 10 and Khumal 8 were found to produce significantly higher yield.
