Effect of Different Seeding Rates on Growth and Yield of Common Bean

Abstract

Legumes are one of the most important sources of protein in the diet of many people in developing countries. The protein content of legumes is about twice that of grains, and plant based production of legumes has numerous advantages over animal protein supply in terms of cost and consumer health; the best plant based protein belongs to the common bean, which contains all essential amino acids for the human body. The experiment laid out in a randomized complete block design with three replications, a field experiment was conducted at the agriculture faculty of Kunduz University farm during the cropping season of 2023, the study aimed to investigate the effect of different seeding rates on the growth and yield of common bean viz. 125 kg/ha, 150 kg/ha, 175 kg/ha, 200 kg/ha and 225 kg/ha. The result showed that the best seeding rate was 200 kg/ha, which resulted in significantly higher plant height (39.87cm), leaf area (335.88cm²), branches/plant (9.89), dry Matter (6.43 gr/plant), pods/plant (13.27), seeds/pod (5.26), 100 seed weight (30.80gr), grain yield (2210.99 kg/ha), Stover yield (4500.00 kg/ha), gross return (265319 AFN/ha), net return (229233 AFN/ha) and B: Cost Ratio (6.33) followed by seeding of 175 kg/ha, the minimum growth and yield were in seeding rate of 125 kg/ha. It can be concluded that selecting the appropriate seeding rate is crucial for optimizing the growth and yield of common bean.
