الملخص الإنجليزي

Pot experiment was conducted to determine the effect of three levels of nitrogen 0, 25, and 35 kg urea ha-1and seed size (7, 8, 9 mm) on chick pea component.

A factorial experiment consisting of nine treatments in each replication laid out in Randomized Complete Block Design (RCBD) with three replications local variety of chick pea was used, the studied traits were, plant height (cm)2 number of nodule plant-1, secondary branches plant dry weight (g), number of pods plant-1, 100- seed weight (g) and seed yield plant (g).

Result related to the nitrogen levels showed highly significantly of all traits while the seed size exhibited significant effect on all traits except dry weight and number of secondary branches plant-1.

The highest plant height (36.12 cm), dry weight (23.41g), number of secondary branches (30.77), number of nodule plant (6.57).

number of pod plant-1(23.17), number of seeds plant-1 (23.77), 100 seed weight (22.70g) and yield plant-1 (33.25 g) were obtained from add 25 kg urea ha-1, while the highest values were recorded from large size (9 mm) for all measured parameters.

The interaction between nitrogen levels and seed size, the results showed highly significant effect on plant height, number of nodule plant-1 and 100- seed weight and non-significant for the rest traits.

From this study the nitrogen and seed size played an important role to improve harvest ability by increasing vegetative growth in early growth stage and increase nodules formation percent 59% .

Also the results revealed significant and highly significant positive correlation among studied traits and the values ranged between 0.458 number of nodules plant with plant height and 0.964 between plant height and number of seed per palnt-1.
