Abstract

                                The field studies on the effect of irrigation and fertilization on production potential of gram (Cicer arietinum L.) during 1979-80 and 1980-81 revealed that it responded favourably to one irrigation applied at preflowering stage (45 days after sowing) along with full recommended fertilizer dose of 20-60-30. One more post sowing irrigation was not found beneficial. The mean maximum water use efficiency (167,4 kg grain / cm ha) and nutrient response (33 82 kg grain/kg nutrient applied) were obtained, respectively under control irrigation (T.) and 33.3% of recommended fertilizer dose (F,). In the other way, lower water use efficiency and nutrient response wore obtained under 1, F, because of less unit increase in grain yield with each unit addition of fertilizer and irrigation water over 1. F..
