Abstract
Two experiments were conducted for three seasons 2000/01, 2001/02 and 2002/03 in the experimental farm of Faculty of Agriculture, University of Khartoum. The first experiment studied the effect of fertilizer, irrigation interval, cultivars and their interaction on some growth and yield components of chickpea. The second experiment studied the effect of cultivars, time of fertilizer application on some growth and yield components of chickpea. The effect of irrigation interval was significant on plant height, number of pods plant-1 and grain yield in kg ha-1 in the first season, however, its effect on the above parameters in the second and third seasons were not significant. Also, its effect on the number of branches plant-1, number of plants m-2 and 100 grain weight was not significant in the three seasons. Application of fertilizer had a significant effect on plant height in the first season, and also had significant effect on the number of pods plant-1 in the second season and had a significant effect on grain yield in kgha-1 and 100 grain weight in the third season. The effect of fertilizer on the above parameters in the other season was not significant. Fertilizer showed no significant effect on number of branches plant-1 and the number of plant m-2 in the three seasons. Shendi cultivar had significantly taller plants, higher number of branches plant-1 than Wadhamid in the first and third seasons; lower, in the second season the performance of the two cultivars was similar. Shendi gave significantly higher number of pods plant-1 and higher grain yield kgha-1 than Wadhamid in the first season, however, the difference between the two cultivar was not significant in the second and third seasons. Wadhamid had showed significantly large seed size than Shendi in the first season but the difference between the two cultivars was not significant in the second and third seasons. The differences between the two cultivars were not significant in the number of plants m-2 in the three seasons. Time of fertilizer application had a significant effect on the number of plant m-2 in second and third seasons, also, it had a significant effect on 100 grain weight and number of branches plant-1 in the third season. It no significant effect, on the other hand, was observed on plant height, grain yield kg ha-1 and number of pods plant-1 in the second and third seasons. Also it had no significant effect on the number of branches plant-1 and 100 grain weight in the second season.
