Abstract

A field experiment was carried out in Diyala Governorate – Al-Muqdadiya district for the summer agricultural season 2021. The experiment was applied according to the design of the complete random sectors, RCBDIn a factorial experiment with two factors. First factor was humic acid with two levels (added and without addition).  Second factor was weed control with five levels (weedy, manual cleaning, bentazone, fusilade, and bentazone with fusilade). seeds were planted on 5/7/2021 and followed a fertilization system by adding phosphate fertilizer In the form of triple super phosphate P2O5 at a rate of 80 kg.ha-1 in one batch when preparing the land before planting by mixing compost with the soil, and urea nitrogen fertilizer (46% N) was added at a rate of 40 kg.ha-1 in two batches, the first when planting and the second when starting the flowering stage ( According to the recommendation of the Iraqi Ministry of Agriculture) pesticides were sprayed in the stage of (2-4) leaves for broad-leaved bush and (3-6) leaves for thin-leaved bush. polynomial at the 5% level of significance.

The results obtained are summarized as follows :

The manual cleaning treatment achieved the highest significant value in plant height (138.76) cm, leaf area (9477.6) cm2 and pod length (8.43) cm, followed significantly by the Fuseland treatment for the indicated traits (123.36) cm, (7771.5) cm2 (7.20). cm respectively.
