Description A field experiment entitled “Response of rice cultivars to different crop establishment
methods.” was conducted during kharif season 2010-11 at Rice Research Station, Kaul
(Kaithal) of CCS Haryana Agricultural University, Hisar, on clay-loam soil which was in
alkaline in reaction, low in organic carbon and available nitrogen, medium in available
phosphorous and high in potassium to evaluate the performance of rice cultivars viz. HSD-1,
HKR-47 (both semi-dwarf high yielding) and CSR-30 (tall scented) under three crop
establishment methods viz. direct seeding, System of Rice Intensification (SRI) and
transplanting. Transplanting method recorded significantly higher number of tillers/m2 and
dry matter production over direct seeding and SRI. The highest numbers of panicle/m2 were
obtained with transplanting whereas SRI gave highest number of grains/panicle. When
averaged over the cultivars, transplanting gave the highest grain yield, which was
significantly higher than SRI (19.7%) and direct seeding (28.6%) but water use efficiency
(WUE) was the highest with direct seeding, SRI also out yield direct seeding. The interaction
between establishment methods and cultivars was found significant which revealed that the
yield of high yielding cultivars was significantly higher in transplanting as compared to SRI
and direct seeding, whereas the yield of tall scented rice (CSR-30) under transplanting was
comparable to that under direct seeding. Direct seeding and SRI method saved 23.4% and
9.9% water, respectively over transplanting. Transplanting was found more profitable than
direct seeding and SRI.
