Identify Certain Physiological Indices Associated with Tillering, Number of Leaves and Leaf Area in Tolerance in Rice

Number of tillers per hill under each treatment was recorded by visual counting of the appropriate stage. The plants already tagged for this purpose were used and average tillers per hill was computed. More numbers of tillers shown in tolerant varieties- Usar Dhan -3 and CSR-23 & less in susceptible IR-42, CSR-23 total number of leaves were counted for three randomly selected plants at different successive stage of crop growth i. e.15, 45 and 75 days and expressed as number of leaves hill. More number of leaves shown in tolerant verieties (Usar Dhan-3, CSR-23) in comparison to susceptible varieties (IR-42, CSR-28).
