A field experiment was performed to evaluate the effects of tillage systems and fertilizer management on the growth and nutrient uptakein soybean. The plant height, fresh weightand dry weight of conventional tillage(CT) weremuch higher those observed for no-tillage (NT). The highest plant height (128.47 cm) was observed in CT with chemical fertilizer. The plant nitrate concentration was higher (2.29%) in NT with green manure than chemical fertilization. However, nitrogen increased steadily in all treatments, and the highest quantity of total nitrogen (476.7 Kg/ha) was observed in NT with green manure. The NO3-N content in the soil decreased gradually just after the vegetative stage. Tillage practices and additional fertilizer application was less effective on the uptake of N, P and K in soybean seeds as compared to NT with green manure. Theresults postulatedthat NT strategies with fertilizers mightinfluence thegrowth characteristics and mineral uptake in soybean.
