Abstract

An experiment was conducted on Tirhut Agricultural College Farm, Dholi [Muzaffarpur], Bihar during kharif seasons of 1974 and 1975 to find out the effect of pyrites and fertilizers on growth and yield of rice. The treatments consisted of five levels of pyrits [0, 1.5, 3.0, 4.5 and 6.0 tonnes/ha) alloted to main plots treat- ments and five levels of fertilizers 10. 25, 50, 75 and 100 per cent of the recom- mended dose of NPK] in the sub-plots. The test varieties were IR 20 during 1974 and Sita in 1975. The maximum grain yield and net return was obtained with the application of 1.5 t/ha of pyrites during 1974 and 1975. Grain yield and net return was maximum with 100 per cent recommended dose [100 N, 60 P.0, and K,0 kg/ha) of fertilizers. Interaction was not significant.
