Response of different phenophase under summer guar gum conditions (<em>Cyamopsis tetragonoloba </em>(L.) Taub.)

Abstract

An experiment was conducted on clay loam soil, at Agronomy farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the summer season of 2015. To investigate the effect of irrigation levels and spacings on growing degree days and correlation coefficient of summer guar gum. The study revealed that, among the irrigation levels yield and yield attributing traits differ significantly correlated. Number of pods plant-1(0.747) and number of seeds pod-1 (0.719) with seed yield plant-1 showed highly significant correlations. Days required for completion of different phenophases were significantly influenced by irrigation level at 0.6 IW/CPE recorded significantly less days required for completion of different phenophases at growth stages i.e. 50% flowering, pod initiation, pod filling stage and harvesting as compared to other irrigation levels. Irrigation level at 1.2 IW/CPE recorded significantly higher growing degree days (day 0C) at different phenophases i.e. 50% flowering, pod initiation, pod filling and harvesting than other irrigation levels.
