Abstract

The experiment was carried out in the fields to the College of Agriculture, Kirkuk University / Al -Sayada for the season 2020-2021. To study the effect of spraying the leafs with foliar fertilization on the growth and yield of bean (using three types of foliar fertilizers of different composition, as coefficients of NP sprays) and the treatment of different types of fertilizers.15 -30-15, fertilizer 02-2-13 and fertilizer 20-20-20 and the control treatment without adding foliar fertilizer and using distilled water. The experiment was designed according to the design of the complete random block (RCBD)and with three replications. The treit were studied (plant height, number of branches, number of pods, number of seeds, and pod weight per plant, weight of 100 grains, number of seeds per plant, biological yield and total grain yield).
The superiority of the fertilizer treatments 15-30-15 as well as the fertilizer 13-6-40 with an insignificant difference between them in all the studied traits over the
fertilizer treatments 20-20-20 and the treatment without spraying, so We recommend spraying the bean crop with a foliar fertilizer containing a high percentage of phosphorus 30 and a fertilizer containing potassium 40 to give the highest yield of branches, pods, biological yield and grains.
