Abstract

A field experiment was conducted during 2012 at Gujarat to study the varietal response of summer cluster bean (Cymopsistetragonoloba L.) to different irrigation scheduling (IW: CPE ratios) under middle Gujarat conditions. The field experiment was laid out in strip plot design with four replications. Irrigation applied at (I2) 0.8 IW: CPE ratio (Common irrigation + 7) had pronounced effect on plant height (32.63, 43.48 and 75.23 cm) at (30, 60 and 90 DAS), respectively, the highest seed (1489 kg ha-1), gotar yield (4325 kg ha-1) and treatment cost (2490
) compare than other irrigation scheduling as (I0) Control (critical growth stage as Branching, Flowering and Pod formation) (Common irrigation + 3) total four irrigation, (I1) 0.6 IW: CPE ratio(Common irrigation + 6) total seven irrigation and (I3) 1.0 IW: CPE ratio(Common irrigation + 8) total nine irrigation. PusaNavbahar (PNB) recorded the maximum plant height (30.95, 41.59 and 81.28 cm) at (30, 60 and 90 DAS) respectively, the highest seed (1429 kg ha-1), guitar yield (4076 kg ha-1) and treatment cost (4620
) than the others. The maximum percent of soil moisture was extracted from 0-15 cm soil depth, followed by 15-30 cm soil depth for all the treatments of irrigation.
