Summary of MSc. Thesis

Four trials were done during this study. Experiment 1. done to study the effect of year seasons, summer, Kharif and winter to sorghum forage production especially during winter season which it done twice season 2005/2006 and 2006/2007. Sorghum cultivars used were Dibeikri, Kambal, R5, Mugud, Himeisi and Wad Ahmed. There were high significant differences between seasons and between entries in each season and in interaction between varieties x seasons, indicated existence of high reaction between genotypes and environment. Maximum yield obtained by growing in each season an adapted varieties, Dibeikri and Kambal for summer and Kharif and Mugud for winter. Himeisi , Kambal and  R5 cultivars were better for forage quality , contained higher protein content. Mugud and Dibeikri had lower digestibility, contained higher percentage of NDF.

                Second trial was done to compare forage production between four sorghum cultivars: Dibeikri, Kambal, Mugud and Samani, maize cultivar Hudeiba2 and sorghum x Sudan grass hybrid (PAN888), during two winter seasons 2005/2006 and 2006/2007. The study illustrated existence of high significant difference between entries and between two seasons. Hudeiba2 out yielded other entries in two seasons in forage yield. In  forage quality characters like crude protein percentage sorghum cultivars were better than maize cultivar, because they contained higher percentages of crude protein..

                Third trial was done to study the effects of sorghum hybrids on forage production during two winter seasons 2005/2006 and 2006/2007.

 Hybrids exceeded their respective better parent in forage yield an in for-

 age quality characters like crude protein percentage

                Experiment 4. done to study the performance of sorghum cultivars: Dibeikri, Wad Ahmed and R5 to different concentrations of sodium chloride solutions (salinity): 0.1Ec, 6Ec, 8Ec and 10Ec. The study clarified that increase concentration and duration coupled with decrease in plant height, leaf length, leaf width and leaf number, detected from 62.1 %, 29.2 %, 71.4 %, and 34.3 % decreases in high concentration over fifth week in these characters. Concentration 10Ec more effective than others. Control treatment 0.1Ec (tap water) the best for all parameters. R5 more tolerant for all parameters measured followed by Wad Ahmed ,whereas Dibeikri ranked lowest.
