Abstract

The study presents a technique for computing soil moisture balance of paddy crop based on 10 years data from 1977-1988 except 1984 and 1987, from agro-meteorological observatory, Raipur Values of different components of the moisture balance have been determined and discussed. The stress values have been used to estimate possible yield reduction by devising an yield index.

 

The study revealed that water demand of the plant is largest between tillering and reproductive stages. Dry matter production appears directly related to the consumptive water use. A significant association is observed between the yield index and the actual rice yield.
