Abstract


Investigations carried out at the Agricultural Research Station. Aliyamagar, Tamil Nadu. India during 1993-94 and 1994-95 revealed that irrigation one day after disappearance of ponded, water is the optimum irrigation regime for rice. Water requirement of rice varied from 932 nun to 1138 mm based on the irrigation regime and variety. The management practices of maintaining a population of 33 hills m2 adopting equidistant method of planting four seedlings hill proved to be feasible and best for yield maximisation under conditions of labour shortage. Varieties CO 45 and ADT 38 performed better than IR 20 with regard to grain yield and economics.
