| Annually about 0.2 million hectares of farms in Iran country are not harvested. The main reason of not harvested area is the lack of a suitable machine for harvesting small and rough fields. To prevent damage caused by not harvested area, a machine with a 1 m length cutter bar and 6.5 hp engines that was suitable for small farms, having high reliability and manoeuvrability on rough terrain was designed, fabricated and evaluated. The results of machine performance evaluation showed that forward speed has a significant effect on field efficiency and crop losses. Increasing the machine forward speed caused decreasing the field efficiency and increasing crop losses. The forward speed of 0.5 m/s had the lowest crop losses and was less exhausting and had the... |

| The present study was conducted in response to the lack of information on effects of cultivar and harvesting time on nutritional value of barley grown in Iran. The objective of this study was to determine the detailed chemical composition of barley in different cultivar and harvesting time and predict the nutrient composition. Three barley cultivars (Ansar, Abidar and Sahand), were harvested at two stages of growth (ripening of grain GS-91 and forage barley GS-83) and nutrition indices of treatments were determined in the advanced nutrition lab. The results of analysis showed that the effect of harvesting time and cultivar were significant on minerals and crude protein of barley, also the effect of harvesting time was significant on gross energy and crud... |
