Description A field experiment was conducted during the kharif season of 2014 at Chaudhary Charan
Singh Haryana Agricultural University, Regional Research Station, Karnal, India to evaluate three
genotypes of scented basmati rice (PB 1121,HB 2 and CSR 30), six coarse grain rice genotypes (HKR
47, HKR 48, HKR 127, HKR 128, PR121 and PR 122.) and one hybrid (HSD 1) under direct seeding
(vattar) and puddled transplanting in a strip plot design with three replications.
Between two methods of planting, plant height, , number of tillers, leaf area index, number of
effective tillers and net returns were higher under direct seeded rice (DSR) as compared to puddled
transplant rice (PTR). Plant population and plant dry weight were not affected by the two methods of
crop establishment. Panicle length, number of grains per panicle, grain, straw yield, biological yield,
1000-grain weight, total variable cost and gross returns were higher under PTR as compared to DSR.
Among different rice genotypes, plant height, number of tillers, panicle length and B: C ratio
were higher in basmati genotypes as compared to coarse grain genotypes except HKR 48. On the other
hand, dry weight, number of grains per panicle, grain yield, straw yield, biological yield, harvest index,
total variable cost and gross returns were higher in coarse grain genotypes. Maximum 1000-grain
weight was recorded in genotype PB 1121. Among coarse grain genotypes, highest number of tillers,
leaf area index, dry weight, number of effective tillers, 1000-grain weight, grain yield, harvest index,
gross returns, net returns and B:C were recorded in HKR 48 and plant height in HKR128.
Interaction between establishment methods and rice genotypes indicated that the plant height,
number of tillers, leaf area, number of effective tillers and net returns of basmati rice genotypes (PB
1121, HB 2 and CSR 30) were higher under DSR as compared to PTR whereas panicle length, number
of grains per panicle, 1000 grain weight and harvest index were higher under PTR as compared to
DSR. Plant population, dry weight, grain yield and biological yield of basmati rice genotypes (PB 1121
and CSR 30) showed no differences under DSR and PTR. The results indicated the suitability of
basmati rice genotypes (PB 1121, HB 2 and CSR 30) for direct seeding. In coarse grain genotypes,
plant height, number of tillers, leaf area, number of effective tillers, net returns and B:C were higher
under DSR than PTR while panicle length, number of grains per panicle, 1000 grain weight and harvest
index were higher under PTR than DSR. There was significant reduction in grain yield of coarse grain
genotypes of rice, viz. HKR 47, HKR 48, HKR 127, HKR 128, PR 121 and PR 122 under DSR over
PTR. Least reduction in grain yield under direct seeding was recorded in coarse grain genotype HKR48
with maximum grain yield recorded under DSR. Grain yield under DSR was lower than PTR in all
genotypes.
