Effect of crop establishment methods and organic manures on the growth of black aromatic rice

Abstract

A field experiment was conducted at the College of Agriculture, CAU, Imphal, Manipur during the kharif season of 2017-18. The design was carried out in split plot with 12 treatments replicated thrice. Crop establishment methods and organic manures had significant impact on growth. The recent data revealed that among the crop establishment methods in both the season S3 (System of Rice Intensification) resulted in marked increased in growth parameters, viz. plant height, total number of tillers per hill and days to 50 % flowering also earlier in S3. But leaf area index and dry matter accumulation (g/m2) were highest in S2 (Transplanting conventional method) as compared with other establishment methods. Among the manurial combination treatments N1 (Recommended dose of fertilizer) recorded highest growth parameters in first season which was at par with the N4 (50% FYM + 50 % Loktak phumdi compost) and in second season N4 (50% FYM + 50% Loktak phumdi compost) showed higher growth parameters.
