Abstract

A field experiment was conducted in the Mandali of Diyala governorate during the fall season 2021 to study the effect of fulvic acid by adding five levels (control, 150 kg ha-1, 300 kg ha-1, 2.5 g L-1and 5 g L-1) and seaweed by foliar application (control, 3 ml L-1and 6 ml L-1) in the growth and yield of broccoli and some soil characteristics. The experiment was carried out according to a randomized complete block design (RCBD) as a factorial experiment with three .The results showed that the levels of fulvic acid were superior in most of the studied traits compared to the control treatment and the intraction between fulvic acid and seaweed in all studied traits compared to the comparison treatment. The results showed the following, the superiority of the level of ground addition with fulvic acid at a concentration of, the level of spraying fulvic acid at a concentration of 2.5 g L-1 (F3) exceeded the height of the plant ,weight of the flower disk, total yield and total leaf area , with a value of 61.12. cm, plant-1, 765.4 g, 23.93 tons ha-1and 386.6 dm2 respectively. As for spraying seaweed extract, the results showed that the concentration of 6 ml L-1 (S2) exceeded flower disc weight, total yield with a value of 753.8 g , 23.55 tons ha-1 respectively.
