Description A field experiment was conducted during the kharif season of 2011 at Chaudhary Charan
Singh Haryana Agricultural University, Regional Research Station, Karnal, India to study the
comparative performance of two varieties of scented/basmati rice (CSR 30 and PB 1121) and four
coarse grain rice varieties (PR 114, HKR 127, HKR 47 and HKR 48) under unpuddle direct seeding
(vattar), zero tillage (ZT) direct seeding and puddle manual transplant situations in a split plot design
with four replications.
Among different methods, plant dry weight, number of tillers, number of effective tillers,
number of chaffy grains per panicle and net returns were higher under direct seeded rice(DSR) as
compared to puddle manual transplant rice(PTR). Plant height, straw yield and 1000-grain weight were
statistically at par among different methods. However, panicle length, number of grains per panicle,
grain and biological yield, total variable cost and gross returns were higher under PTR as compared to
DSR.
Among different varieties, plant height, number of tillers, panicle length and B:C were higher
inbasmati varieties as compared to coarse grain varieties 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 varieties. Maximum 1000-grain weight was
recorded in PB 1121. Among coarse grain varieties, highest plant height, number of tillers, dry weight,
number of effective tillers, 1000-grain weight, grain and biological yield, harvest index, gross returns,
net returns and B:C were recorded in HKR 48.
Interactional effects further indicated that the plant height, number of tillers, number of
effective tillers, dry weight and net returns of basmati rice cultivars (CSR30 and PB1121) were higher
under DSR as compared to PTR and panicle length, number of grains per panicle were higher under
PTR as compared to DSR. Grain yield and biological yield of basmati rice cultivars under unpuddle
DSR were at par with PTR. The results indicated the suitability of basmati rice cultivars (CSR 30 and
PB 1121) for direct seeding.In coarse grain varieties, plant height, number of tillers, dry weight,
number of effective tillers, net returns and B:C were higher under DSR as compared to PTR. While,
panicle length and number of grains per panicle were higher under PTR. There was significant
reduction in grain yields of all coarse grain cultivars of rice, viz. PR114, HKR127, HKR47 and HKR48
under DSR as compared to PTR. However, among coarse grain varieties, the least reduction in grain
yield under direct seeding was recorded in HKR48 with maximum grain yield under unpuddle- DSR.
Grain yield under ZT-DSR was lower than other planting methods particularly in some coarse grain
varieties.
