On-farm assessment of direct-seeded rice production system under central Punjab conditions
Abstract: The field experiments were conducted at farmer’s fields at nine different locations in district Ludhiana and Rupnagar of central Punjab during kharif 2012. Puddled Transplanted Rice (PTR) and Direct Seeded Rice (DSR) production systems were compared in respect of weed infestation, grain yield and economics. The results revealed that plant height, panicle length, number of grains per panicle, number of empty grains per panicle and test weight of two systems was not significantly affected. Average Plant population/m2 was significantly more in DSR (24.0) than PTR (19.2). Number of effective tillers which are the major determinants of grain yield were significantly higher in puddled transplanted rice (272.9/m2) than direct seeded rice (263.3/ m2). Significantly higher grain yield (55.56 q/ha) was observed with Puddled Transplanted Rice (PTR) than Direct Seeded Rice (53.72 q/ha) when averaged over 9 locations. The population of weeds at 30 days after sowing was significantly more in DSR (24.3/m2) than PTR (13.8/m2). The average net returns under PTR (47.71 X 103 Rs/ha) were higher than DSR (47.08 X 103 Rs/ha) but benefit cost ratio was significantly more in DSR plots.
