Effect of Poultry Manure Fertilizer and Dry Yeast on Seed Yield Characteristics of Two Bean Varieties

Abstract

The study was carried out in the vegetable research experimental field of the Department of Horticulture and Landscape design /College of Agriculture and Forestry/University of Mosul/Touristic Forest Area, during the growing season spring 2023. Two types of imported bean seeds were used in the experiment: the first Iranian variety and the second Argentinian variety. The second factor was organic fertilizer, poultry waste, at three levels (0, 1, and 2) tons/donum, and the third factor was dry baker’s yeast, which included three concentrations of dry yeast at (0,5,10 g/L). Data were recorded on the following characteristics: number of seeds per pod, weight of 100 seeds (g), length and diameter of the seed (cm), number of seeds per plant, seed yield per plant (gm), seed yield per unit area (kg/dunum). The level of 2 tons per dunum of poultry manure achieved the highest length and diameter of the seed and the number of seeds per plant. The best results were when spraying beans at a concentration of 10 grams per liter of dry yeast for traits of number of seeds per pod, the weight of 100 seeds, and the length and diameter of the seed at a concentration of 5 grams per liter of yeast, the highest value was achieved significant in the characteristics of the number of seeds per plant. The double interaction between poultry waste fertilizer 2 tons per dunum and 0 gm each of dry baker’s yeast resulted in the highest seed yield for the plant, while the double interaction treatment between poultry waste fertilizer 2 tons per dunum and the variety achieved the best significant results for the traits. Weight of 100 seeds and length of seed diameter.
