Effect of chitosan by seed priming and foliar application on growth and yield of Wal (Lablab purpureus L. Sweet) under water stress

Abstract

The present investigation entitled “Effect of Chitosan by seed priming and foliar application on growth and yield of Wal (Lablab purpureus L. Sweet) under water stress” was carried out at Research and Education farm, Department of Agricultural Botany, College of Agriculture, during the rabi 2021-22. Observations were recorded in context with phenological, morphological, physiological, biochemical and yield contributing parameters. There was a broad range of variability for the different morpho-physiological and biochemical characteristics among all treatments of chitosan under moisture stress. Among all interaction treatments P2F2 was found to be significantly superior reporting better performance in context with plant height, leaf area index, total chlorophyll content, number of pods and seed yield when compared with rest of the treatments. Thus, the current study revealed that the use of foliar spray of chitosan (200 ppm) along with seed priming with chitosan (2%) enhanced the yield of lablab bean grown under water stress condition.
