Effect of Fermented Wheat Residues with Agaricus bisporus and Spraying Potassium and Boron on Growth and Yield of Cucurbita Squash.

Abstract

The College of Agriculture / University of Kufa’s Agricultural Research Station conducted a field experiment in 2022 to determine the effects of fertilizing with Agaricus bisporus fungus residues and spraying shoots with potassium and boron on squash plant Cucurbita pepo hybrid cultivar Squash Ahmed F1’s vegetative growth and yield. The experiment had two variables. Initial factors included The first factor is adding vegetable residues fermented (organic matter) at 0, 1, 2 grams. Plant 1. Second, it involved spraying three concentrations of potassium, boron, and their combination on vegetative growth. The experiment used a factorial design (3 × 4) with R.C.B.D. and three replications, totaling 36 experimental units. After an ANOVA, the averages were compared using the least significant difference test. With 0.05 probability. The study found that 1 g of fungal residue in fertilization was effective. Spraying at a K and P concentration of led to in increasing the vegetative growth characteristics, as the plant height and the number of leaves, leaf area, dry weight of the shoot, and the percentage of total chlorophyll, compared with control. Plant-1 was significantly affected increase in height, number of leaves, dry weight, and amount of yield.
