In order to investigation the effects of Zn rates and application forms on protein and element contents (Fe, Cu, Mn, N and Zn) in bean plant, an experiment was conducted as a factorial based on completely randomized design at greenhouse conditions during 2006. Treatments were included zinc rates in 4 levels (10, 20, 30 and 40 mg Zn kg(-1) soil(-1) in ZnSO4 source) and 3 application forms (soil application, seed pelleting and foliar spraying). Results showed that Zn rates had significant effect on accumulation of Zn, Cu, Mn and N in bean leaves.

In 2005, a split-split experiment in the basis of randomized complete block design with 3 replications and 3 factors were used in which fertilizer rate (100, 150 and 200 kg ha(-1) from urea source), fertilizer split application (3 levels in variable ratios in transplanting, tillering and heading stages and cultivars (Tarom, Shafagh and Bahar1) were the treatments. Results showed that nitrogen fertilizer rates and split application had significant effect on dry matter remobilization amount in total shoot, stem and leaves (except flag leaf) in which among cultivars, Shafagh had the highest amount in terms of stem and total shoot dry matter remobilization.
