Özet

This research was carried in Thrace Region of Turkey (40 degrees 59' K - 2T34' D; 20 m) experiment area in 2018-2019 years in order to determine water-yield relationships of Sorghum-Sudan Grass Hybrid (Sorghum Bicolor-Sorghum Sudanence). In the study, which was planned with three replications according to the trial pattern of random parcels using Sorghum Sudan grass hybrid seed, eight different irrigation treatments were sawed following the form when the plant height reached an average of 95-105 cm. These have been irrigated and rain-fed following some saw and irrigated and rain-fed after all saws. According to the results of the research, the highest yield of green weed, 5.03 and 5.02 t da(-1) were obtained from the treatments irrigated (III) following all the saws and irrigated (ITO) following the first two saws, respectively. Although the irrigation has an important effect on the increase in yield after the first saw, it has been observed that irrigation will be sufficient following the first two saws, the irrigation is not effective in the yield increase after the second or third saw, and there is no need for irrigation after the third saw. If a single irrigation is required, this should be done following the first saw. Treatments RI and 001) that were not irrigated in the second saws period but third saws were irrigated, irrigation applied has not been as it could not reach the harvest size. In the non-irrigated treatment (000) could not reach harvest size in the third saw periods. Under Tekirdag conditions, Sorghum Sudan grass hybrid plant was found to be unsuitable for dry farming. The relationship between seasonal evapotranspiration and green weed yield was statistically significant (p <= 0.01) and it can be defined by equation of Y= 5.06 ET + 2043.3 (r = 0.82**). Again, for the total growing season, the water yield responce factor (ky) between evapotranspiration and green weed yield was calculated as 0.66.
