Sažetak

The aim of this experiment was to evaluate the effects of phosphorus rate and iron foliar application on growth and yield of green bean (Phaseolus vulgaris L.). A field experiment was conducted at Roudsar, northern Iran, from mid-March to early September of 2013. Factors were the iron foliar application rate (0, 1, 2, 3, 4 g L-1 of Sequestrene 138Fe, Iron Chelate 6%) and phosphorus fertilizer rates (0, 50, and 100 kg P2O5 ha-1 as triple superphosphate). Treatments were assigned in a factorial arrangement in a randomized complete block design with three replicates. ANOVA indicated that pod yield and pod number per plant were significantly influenced by both phosphorus fertilizer rate and iron foliar application. Results showed that total pod yield was increased by 32% when P application rate increased from 0 to 100 kg ha–1. At the same time, pod yield was increased by 46% as Fe foliar application rate increased from 0 to 2 g L-1 and thereafter relatively remained constant. Based on the results of this study, P application at the rate of 100 kg ha-1 and Fe foliar application at the rate of 2 g L-1 are recommended for obtaining the highest pod yield in green bean.
