ABSTRACT

Rice production trials using SRI methods in a few locations in Bhutan have shown positive effects. This paper reports the performance of four rice varieties: IR 64, Bajo Maap 2, and Khangma Maap, and a local variety Nyabja using SRI practices conducted at Lobesa. IR 64 showed the highest yield performance of 10.1 t/ha followed closely by Nyabja and Bajo Maap 2 with 9.7 t/ha each. For all varieties tested, the SRI method out yielded the conventional methods. Statistical analysis showed significant differences (p<0.01) in yield among the cultivars and the two methods tested. Input cost for seed, fertilizer and water reduced with SRI methods. These results show that SRI techniques may provide an efficient option for farmers to enhance their rice production.

KEY WORDS:

Lobesa, conventional methods, SRI, yields, varieties, methods.
