Abstract

A field experiment was conducted during the summer season of the year 2009 at Anand Agricultural University, Anand, Gujarat to study the influence of irrigation scheduling (IW: CPE ratios) and plant growth regulators on growth, yield and yield attributes of summer cluster bean. Sixteen treatment combinations consisting of four levels of irrigation schedules (IW: CPE ratios) as a main plot treatments and four plant growth regulators as sub plot treatments tested under split plot design with four replications. The growth is attributed such as plant height and leaf index area was significantly influenced with irrigation schedule as well as plant growth regulators. The yield and yield attributes were maximum affected by I3 treatment of irrigation schedules and application of NAA @ 100ppm at 30 and 60 days after sowing (DAS). The highest green pod yield i.e.19480 and 18854 Kg/ha were observed under irrigation treatment of 1.0 IW: CPE ratio (I3) and application of NAA @ 100 ppm (GR1), respectively. The interaction effect between irrigation schedules and plant growth regulators also significant in green pod yield and it was maximum in IW: CPE ratio 1 with NAA @ 100 ppm.
