| Abstract | ||
| The study aims at constructing regression predictive equations for quantity loss of some varieties of wheat under the effect of different forward speed of harvester. The results showed that the saberbeak variety surpassed significanty in giving the least quantitative loss, maximum performance efficiency and maximum capacity ton/hr, where as the maxibac variety gave the highest quantitative loss and the minimal performance efficiency and the minimal capacity. The speed 1.6 km/hr gave less quantitative loss and maximal performance efficiency and minimal capacity while the speed 4.8 km/hr gave highest quantitative loss and minimal performance efficiency and maximal capacity. The highest positive correlation was between the loss in the separation unit and the threshing unit, highest negative while the correlation was between performance efficiency and cutting unit loss. | ||
