INFLUENCE OF PRE-PLANT TREATMENTS ON SILLAGE MAIZE YIELD IN NO-TILLAGE SYSTEM

No-tillage agricultural practices and pre-plant applications in agricultural systems have become quite common in recent years. In this study, the effect of pre-plant applications on plant characteristics and yield in silage maize cultivation under no-tillage conditions was examined. Plants belonging to the legume (common vetch, narbon vetch and fodder pea) and poaceae (barley, triticale and Italian grass ) families were used as pre-plants materials. Within the scope of the study, the values of plant height, green herb yield, dry matter ratio, dry matter yield, leaf/stem ratio, peak tasselling time and core tasselling time were determined. According to the obtained data, it was observed that the yield of maize was higher in the parcels where the legume family plants were used as pre-plants. Among the legumes, common vetch was determined to increase the maize yield higher than other plants. It was noted that the plants included in poaceae family caused a decrease in the maize yield. When the results of the study were evaluated, it was concluded that legume plants should be selected as pre-plant in no-tillage silage maize cultivation, good results were obtained from especially common vetch, and cereals had a negative effect on the plants grown after them.
