The aim of this study which was conducted in the summer of 2001 on the trial fields of Van YYU (Yuzuncu Yil University) was to determine the effects of Maxicrop leaf fertilizer, applied on Beason soybean at various stages, on the yield and yield components. Maxicrop doses of 500, 1000 and 1500 g. ha(-1) per hectare were applied at three different stages of the plant (seed stage, four-leaf stage and '' beginning of blooming '' stage). The highest plant height was achieved as 32.98 cm on average from 2000 g. ha(-1) dose. No difference was recorded between the applications in terms of 1000 seed weight. The values of 1000 seed weight varied between 134.25 - 144.25 g on average. Application doses lead to an increase in seed yield. The highest seed yield value was achieved as 1265.7 kg. ha(-1) from 2000 g. ha(-1) dose while the lowest seed yield was achieved as 997.3 kg. ha(-1) from the control dose.
