Growth and yield response of four chickpea verities to phosphorus fertilizer levels under Sulaimani condition

الملخص EN

A field study initiated in the winter of 2017 in Sulaimani region to investigate the P fertilizer requirements of chickpea, a factorial split-plot experiment; within a randomized complete block design with three replications was used.

cultivars (V1=Flip O1-43C, V2= Flip 99-34C, V3=Hazardmerd, V4=Flip 93-55C), were allocated to main plots.

Sub-plot treatments were three levels of phosphorus applied as triple of (tri super phosphate) % 46 P205 (T1= 0kg/ha, T2= 10kg/ha, T3= 20kg /ha) to study their effects on growth performance and yield of chickpea (Cicer arietinum) during winter season.

Results showed that V2 recorded maximum value for number of branches /plant, number of pods /plant, weight of pods /plant, number of seeds /plant and weight of seed /plant and V3 recorded maximum value for weight of seed /pod and 100 seed weight, while V1 recorded maximum value only for plant height.

It was found that the application of 20 kg P205 /ha recorded highest value of plant height, number of pods /plant, weight of seed /pod, number of seeds /plant and weight of seed /plant.

The interaction between V2 and 20 kg P205 /ha recorded maximum value for number pods /plant and number of seed /plant and interaction between V3 and 10 kg P205 /ha recorded the maximum value for weight of seed /plant A field study initiated in the winter of 2017 in Sulaimani region to investigate the P fertilizer requirements of chickpea, a factorial split-plot experiment; within a randomized complete block design with three replications was used.
