Abstract:: Influences of seed coating foliav agent made by us on soybean devaloping and grain yields were studied in thetest .The results indicated that seed coating significantly inhibited seedling height at early vegetative stage , enhancedstem thickness and root/shoot ratio , particularly the later increased 30 % compared with control .Application of foliar agentat later stage increased photosynthesis , sped up evaporation rate and better regulated water metabolism in the plants ,which , resulted in the increase of pod numbers , seeds per pod and seed size .The results also showed that the soybeanyield in the treatment of opplying seed coating and foliar agent at flowering and seed filing stage in creased 23 .0 %, ofapplying seed coating and foliar agent at seed filling stage increaed 20 .1 %, of applying seed coating and foliat agent otflowering stage , and applying seed coating alone increased 12 .7 % and 10 .2 % respectively than control .
