 ABSTRACT

Afield experiment was carried out during three consecutive  rainy seasons  (2014 to 2016) at Agricultural Research Station, Kota, Rajasthan to compare different methods of rice cultivation in relation to water management practices and productivity  under south eastern, Rajasthan. The experiment was laid out in randomized block design with four replication comprising of 6treatments (irrigation at 100, 125 & 150% PE through sprinkler method with conventional transplanting, irrigation at 5 ± 2 cm standing water and refilling it 1-3 days after disappearance of ponding water through surface method with conventional transplanting, intermittent light  irrigation upto panicle initiations and then shallow standing water through surface method with SRI practices and irrigation at 150% CPE through surface method with DSR). The results revealed that intermittent light irrigation upto panicle initiation and then shallow standing water with SRI method recorded significantly higher plant height (106 cm), effective tillers/m2 (1435), filled spikelet/panicle (135.2), grain yield (5850 kg/ha), straw yield (8495 kg/ha), net return (Rs.135658/ha), B:C ratio (4.13), water productivity (Rs.35.34/ha-M3) and lower weed dry weight at harvest (5.45 g/m2), nitrogen (1.26 kg/ha), phosphorus (0.259 kg/ha) and potassium (1.15 kg/ha) uptake by weeds over irrigation at 100, 125 and 150 % PE through sprinkler method with conventional transplanting  , irrigation at 5 ± 2 cm standing water and refilling it   1-3 days after disappearance of ponding water through surface method with conventional transplanting  and irrigation at 150 % CPE through surface method with direct seeded condition of rice. However, irrigation at 150 PE through sprinkler method with conventional planting, irrigation at 5 ± 2 cm standing water and refilling it   1-3 days after disappearance of ponding water through surface method with conventional transplanting and irrigation at 150 % CPE through surface method with direct seeded condition of rice with respect to growth and yield attributes, grain yield, net return and water use efficiency of rice remained on par and with each other’s
