| Abstract | ||||
| Two field experiments were conducted at Sakha and Sids Agriculture Research Station, ARC, during the two successive summer seasons of 2015 and 2016. Six summer forage crops; sorghum cv. Giza 1, Sudan grass cv. piper black, sorghum cv. SX-17, millet cv. Shandaweel 1, teosinte cv. Sakha and maize Drawa were evaluated in two locations for forage yield and some related traits. Three cuts were taken from the five forage crops and two cuts from Drawa at the same period. Combined analysis of variance revealed significant and highly significant differences for seasons, locations, summer forage crops and most of their interactions on fresh and dry forage yield, plant height, stem diameter, fresh and dry leaf/stem ratio at the two cuts and three cuts and total yield.The interaction effect between forage crops and seasons were more pronounced than between forage crops with the location on some traits, and the opposite for the other traits. Sudangrass (piper black) followed by Sorgo (Giza 1) were the best summer forage crops for fresh and dry forage yield under the study, over environments. While maize (Drawa) was the lowest one. Millet (Shandaweel 1) gave more fresh and dry yield than SX-17 at Sids location, but SX-17 exceeded millet at Sakha location, over the two seasons. Plant height and stem diameter had the same trend of fresh and dry forage yield. Fresh leaf/stem ratio had higher values in the two seasons and their combined at Sakha than at Sids. Teosinte was the best one. Concerning dry leaf/stem ratio values, season 2016 had higher values at Sakha than season 2015 at Sids and teosinte was the best one. It is economically viable to cultivate teosinte at Kafr El-Sheikh Governorate and surrounding areas since it has high palatability and good quality. On the other hand, maize as Drawa not preferable as summer forage crop since it had the lowest fresh and dry forage yield and dry leaf/stem ratio. | ||||
