Abstract
This study was conducted in the summer of 2024 in the Hidaj region of Zanjan province to evaluate the effects of three types of organic fertilizers on agronomic traits and yield of white bean using a randomized complete block design (RCBD) with three replications. The treatments consisted of different mixing ratios of liquid organic fertilizers derived from corn prossing, molasses, and vinasse, applied at a rate of 90 liters per hectare. The treatments included: 100-0-0 (Z1), 75-25-0 (Z2), 75-0-25 (Z3), 50-25-25 (Z4), 0-100-0 (M5), 25-75-0 (M6), 0-75-25 (M7), 25-50-25 (M8), 0-0-100 (V9), 25-0-75 (V10), 0-25-75 (V11), 25-25-50 (V12), and 0-0-0 (C13, control). Among the treatments applied, treatment (Z1) increased plant height, dry weight, number of seeds per plant and grain yield by 18.14, 17.39, 21.34 and 25.82 percent, respectively, compared to the control. Also, treatment (Z2) increased plant height, dry weight, number of seeds per plant and grain yield by 16.72, 21.67, 19.51 and 26.18 percent, respectively, and treatment (M6) increased plant height, dry weight, number of seeds per plant and grain yield by 15.89, 18.27, 18.90 and 21.77 percent, respectively, compared to the control. Considering the cost price of these three types of organic fertilizers, the economic analysis of the studied treatments showed that treatment (Z2) increased yield by 26.17% compared to the control treatment and ultimately led to an increase in net profit equivalent to 0.801 billion rials.
