ABSTRACT
Field experiments were conducted at the Kadawa Irrigation Research Station located in the Sudan savanna ecological zone of Nigeria during the 1995/96 and 1996/97 dry seasons.
The aim was to study the effect of irrigation frequency (5,10,15 and 20 day) and phosphorus level (0,11 and 22kg P/ha) on yield and yield components of three chickpea varieties. The variety K850 out-performed ICCV1 and C235 with respect to 100-seed weight and grain yield in two years of the trial. Effect of variety on number of seeds per pod and grain protein content was significant (P<0.05) in 1995/96 trial only. Irrigation at 10-day interval produced significantly higher grain yield than other intervals in 1996/97 non of the parameters was significantly affected by irrigation treatment in 1995/96 trial. Phosphorus application was only significant on grain yield in 1996/97 trial. Interaction between variety and irrigation frequency and between variety and phosphorus on grain yield were significant (P<0.05). The study showed that in the Sudan savanna ecology of Nigeria, under irrigation, the variety K850 significantly out-yielded C235 and ICCV1 at an irrigation interval of 15 days and 22 kg P/ha.
