A study on crop establishment and harvest indices of green gram and black gram under sodicity stress using organic methods

Abstract

The disturbing features in pulse production are poor establishment and low harvest index. The partitioning efficiency can be improved by physiological manipulations such as spraying of hormones and nutrients that reduce flower drop and thereby facilitate large sink size. To achieve these objectives, a laboratory screening and field study were carried out. Field experiment was conducted under sodic soil condition. six treatment combinations were employed by initial seed treated with Cowpea sprout extract (2%), GA3 50 ppm and Ammonium Molybdate 0.05 % followed by foliar spray with Panchagavya(1%) and Kcl(1%) along with control. From this study it was concluded that Seed treatment with Cowpea sprout extract (2%) + foliar spray of Panchagavya -1.0 % was more effective to increase seed and seedling establishment and yield under sodic soil.
