Abstract

An experiment at Crop Research Centre of G.B. Pant University of Agric. and Tech., Pantnagar in split-plot design during two consecutive years (1991–92 and 1992–93) was conducted during both the seasons (kharif, rice and rabi, wheat). During kharlf season, among rice cultures grain yield was significantly higher (4137 kg/ha during 1991 and 3892 kg/ha during 1992) in transplanted rice over direct sowing either puddled or non-puddled during both the years. Lowest yield (2380 kg/ha during 1991 and 1975 kg/ha during 1992) was obtained in direct sowing unpuddled conditions. Complete failure of the crop was recorded in direct sown (non-puddled) rice during both the years. Both the herbicides pendimethalin and butachlor were equally effective. Grain yield of wheat was not much influenced due to puddled/non-puddled soils (in kharif) during both the years.
