Determination of yield and yield compenents of different planting intervals in silage maize cultivars under Sivas ecological conditions

This study was carried out in three cycles according to the '' Factorial Experimental Design '' in the 2015 vegetation period in order to determine the silage performances of some hybrid corn varieties (Zea mays L.) in the Sivas-Susehri ecological conditions and the effects of different distances on these varieties. In the study, the distances on five different rows (10 cm (14285 plants / da), 13 cm (10989 plants / da), 16 cm (8929 plants / da), 19 cm ) And four different corn varieties (Hido, Kerbanis, 30B74, P0573). In this research, green forage yield, plant height, leaf weight, number of leaf, ear ratio per plant, stem diameter, stem ratio, flowering time, number of cobs in a plant, cob weight, cob rate, dry cob rate, dry stem ratio, dry leaf ratio, dry matter yield and dry matter rate characters were investigated.In the results of research, the effects of different plant density applications on the yield of green weed, plant weight, leaf weight, stem diameter, number of cobs, weight of cob, dry matter yield, dry stem ratio and dry leaf ratio were found statistically significant. The highest green weed yield was obtained in the study as 10836 kg / da, 9434 kg / da and 9841 kg / da, respectively, with 30B74 plant species and 13, 16, 19 cm plant density application. The highest dry matter yield was 3147 kg / da, 2423 kg / da and 2887 kg / da, respectively, with application of 13, 16, 19 cm plant density of 30B74. Different plant frequency applications resulted in the highest dry matter rate from 30 to 22 cm plant density application. As a result, 30B74 variety appeared in the foreground in terms of many features examined among varieties. According to the obtained results, in the ecological conditions and economic production principles of Suşehri the distance of 19 cm for type 30B74 is seem suitable. In order to make definite suggestions, more studies should be done.
