Effect of Different Levels of Irrigation and Potassium on Qualitative and Quantitative Characteristics of the Beans in Yasooj, Iran

Abstract

To study the effects of different levels of irrigation and potassium on Bean components practice, this study was carried out in Yasooj-Iran region in 2012-2013 cultivation year. Factorial experiment with two factors was carried out where the first factor of potassium sulfate fertilizer levels (zero, 100 and 200 kg per hectare) and the second factor of Irrigation (4 days, 8 days and 12 days) in a randomized complete block design were performed in triplicate. Developmental characteristics such as plant height, number of branches, stem diameter, number of pods per plant, seeds per pod, number of seeds per plant, seed weight, seed yield, biological yield and harvest index were measured. Results showed that treatment with potassium sulphate on stem height, number of branches, stem diameter, number of pods, number of seeds per pod, number of seeds per plant, seed weight, seed yield, biological yield and harvest index had a significant effect. The maximum amount of 1000 grains weight and harvest index was observed in the treatment of 100 kg per hectare of potassium sulfate. Irrigation factors on traits such as plant height, shoot fresh weight and seed yield showed a significant effect, the maximum amount of plant height, shoot fresh weight and seed yield was obtained from 4-day irrigation. Applying 100 KG per hectare of potassium sulfate is recommended to increasing of beans grown in.
