Abstract

We must pay attention that in our country severe soil erosion and high percentage from pastures had increased to threefold of their capacity, so providing of forage and protein as a need is very important. This study was carried out as a split -plot and complet random blocks (CRB), at VARAMIN (Pakdasht), Abureyhan high educational complex farm in 1376. It studied three cultivars of FORAGE SORGHUM and the best planting date to get high forage YIELD. Different PLANTING DATES were 3.2.76, 18.2.76, 3.3.76 and 18/3/76 culivars were selected among new ones as: Speedfeed, Sugar graze and Jumbeo. In this study tests were placed in main plots and varieties in minor plots, so It took care the varieties. Forge YIELD accounted for wet and dry weight, the other cahracters were measured as: leaf numbers, shoot diameter, shoot height, rate of leaf / shoot pod weight (ə), leaf surface index and rate of dry / wet weight (ə). Results showed that wet forage in all three varieties at first and second dates 3/2/76, 18/2/76 were put in one group After drying the amount of dry forage for Sugar graze cultivar and planting date 3/2/76 with 34.13 t/ha had showed the highest rate. Leaf number of Sugar graze on 18/2/76 with 22.5 leaves were the most. Shoot diameter and plant height as two clear indexes for Sugar graze cultivar at second planting data with 4.4 cm and 325 cm mean were better than the others. Leaf surface index for Sugar graze at second planting date and for Speedfeed and Jumbo at first planting date 3/2/76 were put in one group. These measured CHARACTERS and results showed that rate of leaf / shoot pod weight and rate of dry/wet weight for Sugar graze cultivar were less than the others. The best treatment (D2.V2) was belonged to Sugar graze variety at second planting date 18/2/76 which was prefered to the otheres in VARAMIN.
