The use of improved strains is one of the easiest and cheapest methods of maximising yields as by this method alone it is possible to get 15 to 20% increased yield. From crop cutting experiments it is seen that the productive capacity of the improved strains increases to 33% in combination with manures. In view of the greater response of the improved strains to manures it should be possible to wipe out a great portion of the deficit by a campaign of intensive manuring in areas of assured water supply where the departmental strains are grown. There are now available strains of paddy evolved by the state suitable for the different tracts and for different seasons.
