Abstract
This experiment was conducted at Grdarasha field of the College of Agricultural
Engineering Science, Salahaddin University in Erbil, with a Clay Loam texture
class. During the spring growing season of 2020, to study the effect of four levels
of phosphorus TSP (0, 20, 40, 60) Kg P. ha-1. Three levels of K (0, 15, 30) Kg K.
ha-1 and three levels of N (0, 15, 30) Kg N. ha-1. Besides, there was a combination of yield components and nutrient balance of the chickpea plant using a splitblock design with three factors (K, N and P), where 36 treatment with 3 replicates
was used.
The main results could be summarized as follows: The combination of potassium,
nitrogen, and phosphorus levels affected the yield of the chickpea plant significantly. Also, the maximum yield recorded in the treatment combination
(K2N1P2) was (1.55 Mg ha-1). In comparison, the lowest mean value (0.73 Mg
ha-1) was recorded from the treatment combination (K0N0P0).
