Effect of Leaf Clipping on Yield Attributes of Modern and Local Rice Varieties

Abstract

Impact of five different types of leaf clipping on the yield attributes of modern (Binadhan-8) and local (Terebaile) rice variety was evaluated on pot experiments following a completely randomized design (CRD) with three replications. Leaves were cut according to the treatment. Data were collected on panicle length (cm), filled grain panicle-1, unfilled grain panicle^-1, thousand grain weight (g), grain weight panicle^-1 (g). In Binadhan-8, flag leaf alone or flag leaf with 2^nd leaf and 2^nd and 3^rd leaves cutting showed profound reduction in grain number panicle-1 (35.14, 62.62, and 51.83%, respectively) and grain weight panicle^-1 (29.18, 58.37 and 48.93%, respectively) while, cutting of 2^nd leaf and 3^rd leaf alone exert no significant impact compared to control. Number of unfilled grain increased with higher intensity of leaf cutting. In Terebaile, only flag leaf cut showed non-significant impact on grain number panicle^-1 and grain weight panicle-1. Profound impact was observed by cutting flag leaf with 2^nd leaf (55.47 and 48.98%, respectively) and flag leaf with 2^nd and 3^rd leaf (58.96 and 63.13%, respectively). Leaf clipping had non-significant effect on thousand grain weight of modern variety Binadhan-8 while, it had significant effect in Terebaile
