Abstarct: In order to evauate thr effects of foliar application, rhizobium inculation and sulfur on soybean cv. Williamse an experiment was carried out as a factorial arrangements, in an RCBD with three replication at Golcheshmeh in 2014.The factor consrstead of spraying at two levels(with and without spraying), Inoculation with R. japanicum at two levels(with and without inoculation), and sulfur of three levels(no sulfur, 65 kg S/ ha and 130kg S/ha). The treatments were applied at two weeding condition.i.e.(no weeding and weeding). The results rereveald that the effects of spraying was significant for plant height, stem diameter, number lanteral branches,pod length, number of sed per pod, percent of leaf turgor, number of pod per plant,1000seed weight, grain yield and oil per cent. Seed inoculation with rhizobium significantly affected all trails studied with the exception of protein content and pod length, Sulfur significantantly affected grain yield, oil and protein content.
