Abstract

The present investigation was carried out with three rice cultivars (AU1 GSR, ADT 46 and BPT 5204) in main plots and five establishment methods (Broadcasting, line sowing, recommended spacing, wider spacing and SRI planting) in sub-plots in split-plot design. Results showed that SRI method produced higher plant height, number of tillers and dry matter accumulation than recommended spacing. SRI produced higher grain yield than recommended spacing and wider spacing, respectively. Among varieties, maximum growth attributes viz., plant height, number of tillers and dry matter accumulation. And Yield parameters like number of productive tillers m-2, filled grains panicle-1, grain yield, straw yield and harvest index was observed with AU1 GSR.
