Effect of Cultivars, Apical Pinching and Copper Nano-Fertilizer on Green Pods Characteristics of Broad Bean (Vicia faba L.) was Fadhiliya area

Abstract

The study was Fadhiliya area (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, 1, and 1.5 milligrams per liter), for a total of 18 (treatments) (2 x 3 x 3). Research was conducted in the field using 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, with a 5% significance level, was used to analyze the data and compare the means. This is how the findings add up: A- Dutch cultivar plants were significantly superior in the number of pods, while the plants of the American cultivar were superior in the yield of pods , while the Spanish and American cultivars were superior in the characteristic of pod weight and length of the pod. B- The treatment of apical pinching excelled in all the studied traits compared to the treatment of no pinching. C- The use of copper Nano-fertilizer at two concentrations of 1 and 1.5 g L^-1 resulted in significant effects on all the studied traits compared to the comparison plants. D- Most of the effects of the binary and triple interactions of the studied factors were consistent with the single effect of each factor for most of the previous characteristics.
