| Abstract/Description: | Field experiments were conducted at the ICAR Sikkim research farm, Tadong located at an altitude of 1450 mamsl in the per- humid mid hill acidic soils during kharif (Rainy season) of 2008 and 2009 to evaluate the performance of four rice (Oryza sativa.L) varieties viz. RCPL 1-87-8' (medium duration 125 days). Pusa Sugandh-2'(medium duration- 130 days), RC Maniphou-7, (long duration- 150 days) and one local cultivar 'Thulo Attey' (long duration, 155 days) under different spacing in system of rice intensification(SRI) compared with conventional rice cultivation. 'RC Maniphou- 7' recorded the highest grain yield (6.73 t/ha), N uptake(124.8 kg/ha), P uptake (40.5 kg/ha),K uptake (84.3 kg/ha), water use efficiency (2.879kg/ha-mm), net return (Rs- 72,750) and benefit : cost (2.09) at 20x20 cm in RCLP 1-87-8, RC- Maniphou-7' and local cv 'Thulo Attey' over conventional rice cultivation. The optimum spacing undr system of rice intensification for RCPL 1-87-8', 'RC Maniphou-7', and local cv 'Thulo Attey' was 20cm x 20cm. 'Pusa sugandh' recorded a 2.0% yield decrease at SRI 10cm x 10cm, as compared to conventional rice cultivation and did not respond to SRI. |
