Influence of Zn and ferrous sulfate on yield and yield component of Phaseolus vulgaris

Abstract

This study was conducted to investigate the effect of various levels of zinc sulfate and ferrous sulfate fertilizers on biological yield, plant height and stem diameter of pod in a bush and the length of main root of pinto bean cultivar (phaseolus vulgaris). A field experiment was conducted in 2013 in Sarvak region of Boyer-Ahmad, Iran. It was a factorial study on the basis of randomized complete block design with treatments including three levels of ferrous sulfate (0, 50, 100 kg / ha) and three levels of zinc sulfate (0,50,100 kg / ha). Data analyses indicated the interaction effect of zinc sulfate and ferrous sulfate on biological yield and stem diameter were significant at 5% level, also observed interaction of zinc sulfate and ferrous sulfate on plant height, economic yield and weight of thousand grain weights were significant at 1% level. Treatments of fe0 zn100, fe100 zn0 produced the maximum (12303 t/ha) and minimum (6030 t/ha) of biological yield respectively.
