In Other to determine the effect of zinc foliar application (Zinc-Fousin 70%) in various rate (0, 0.5, 1 and 1.5 liter per hectare) and various stages of growth (V8-R3) on yield components, yield, oil and protein percentage of two soybean cultivars [(Sahar, Determinate) (Williams, Indeterminate)] in summer cultivation in 2004 at Gorgan, Golestan, Iran. The treatments were arranged in a Factorial Split Plot design based on randomized complete blocks (RCBD) with four replication. The results indicate that zinc foliar application in V8, significantly increased, number of seed per pod, seed yield and harvest index. Also one liter zinc foliar application per hectare significantly increased plant height and percent of seed protein. Cultivar Sahar was superiour than Williams for number of pod per plant, seed yield, percent of seed protein and harvest index. Also, Cultivar Williams for number of seed per pod, number of nod in main stem, plant height and percent of seed oil was superior to cultivar Sahar. positive and significant correlation was observed between seed yield with number of pod per plant, number of seed per pod, one thousand seed weight and harvest index. Among yield components, seed weight (for Williams) and pod number per plant (for Sahar) had the most correlation with seed weight.
