Effect of Cultivars, Apical Pinching and Copper Nano-Fertilizer on 1-Characteristics of Vegetative Growth of Broad Bean (Vicia faba L.)

Abstract

Research was conducted at the vegetable field of the University of Mosul’s Department of Horticulture and Landscape Engineering (in the College of Agriculture and Forestry) (2021). The experiment included a study of three factors, the first of which was the use of three different bean sprout cultivars (Spanish, American, and Dutch), the second of which was the condition of apical pinching (apical pinching and without pinching), and the third of which was the use of copper Nano-fertilizer at three different concentrations (zero, one, and 1.5 gm L-1) (2 x 3 x 3). Field research was conducted utilizing a factorial experiment with split-plots in R.C.B.D. Varieties were planted in the main plots, and the correlation between pinching and copper Nano-fertilizer concentrations was observed in the sub-plots. The Duncan multiple range test was used to compare the means of the groups, and a significance threshold of 5% was used for the study. Here’s a rundown of the A- The significant effect of the plants of the three cultivars varied in the characteristics of the vegetative growth, as the plants of the Spanish and American cultivars were significantly superior in plant height and percentage of dry matter, while the plants of the Dutch and Spanish cultivars excelled in the number of branches, while no significant differences were observed between the cultivars in terms of chlorophyll and leaf area. B- The treatment of apical pinching excelled in terms of the number of branches and leaf area compared to the treatment of not pinching. C- The use of copper Nano-fertilizer in two concentrations resulted in significant effects on all vegetative growth traits compared to comparison plants. D- Most of the effects of the binary and triple interaction of the studied factors were consistent with the single effect of each factor for most of the previous characteristics.
