Field experiments were conducted during kuruvai seasons (June-Sept) of 1994 and 1995 to identify appropriate techniques and suitable rice varieties for direct seeding under puddled condition at Tamil Nadu Rice Research Institute, Aduthurai. Five rice varieties viz., Vikas, IET 9978. IET 9994, IET 9221 and ADT 36 were included during kuruvai 1994 and during 1995, the variety. IET 9221 was replaced by IET 10402 and ASD 16. Four management practices viz., transplanting, wet seeding, weed control and split application of fertilizer were included in the experiments. Grain yield obtained under direct seeding is comparable with transplanted rice. Rice varieties, ADT 36, ASD 16 and JET 9978 are found to perform well under direct sown situation with improved management practices viz., herbicide application followed by one hand weeding and application of recommended dose of N,P,K (125:50:50 kg/ha) and ZnSO4 (25 kg/ha).
