Effect of Zinc spraying on the growth and yield of three cultivars of beans

Abstract

A field experiment was conducted at AL-Hussainyah district of Kerbala /Iraq to study the effect of Zinc spraying on the growth and yield of bean. The experiment included two factors. First factor included Zinc concentrations (0, 30 and 60 ppm). Second factor included three cultivars. of bean. The experiment was designed as according the Randomize Complete Block Design ( RCBD). The result showed the following points:1. The concentrations of zinc Significantly increased plant height and number of pods at60ppm, number of forest,number of seeds, seed weight, rate of seed yield and Biological yield at 30ppm . 2. Height significant different local vari. On other vari. In characters on the plant height, number of forest, number of pods and number of seeds.3. The interaction between (local vari. + 60 ppm) significantly increased plant height, number of forest, number of pods, number of seeds, seed weight , seed yield and Biological yield.
