Abstract: 

Due to zinc deficiency of agricultural lands and fertilizer application problems, use of zinc efficient cultivars is considered a suitable way for the compensation of this deficiency and increasing the yield of the agricultural products. In this research, zinc efficiency of eight common bean cultivars was studied based on the seed yields in two treatments of zinc fertilizer (0 and a 10 mg/kg per soil treatment) in greenhouse condition. The concentration and the uptake of the micronutrients and phosphorus as well as yield component of various cultivars in the two levels of fertilizer was measured. The results showed that the G01437 cultivar with 93% and the Cardinal cultivar with 46% had the most and least zinc efficiency, respectively. The cultivars with more zinc efficiency in the zinc deficient treatment had more seed weight, seed numbers and pod numbers, whereas the response of the cultivars with less zinc efficiency to the zinc application was higher. In the treatment of zinc sufficiency among various cultivars, these characteristics had less difference. The concentration and the uptake of zinc with zinc application increased in all of the cultivars. This increase was more in the cultivars with higher zinc efficiency. The concentration of the other elements with zinc application decreased while their uptakes increased except in the cultivars with higher zinc efficiency. Overall, due to ability of produce higher yield in zinc deficiency conditions, using of the cultivars with higher zinc efficiency is a suitable strategy for the compensation of zinc deficiency in agricultural lands.
