- Abstract
The aim of this research i; to determine the optimum factors affecting mechanical planting of coated marjoram seeds. The studied factor is four forward speed levels. The main results of this study can be summarized as follows: The maximum marjoram seeding rate of 3.50 kg/fad., was obtained at metering-device speed of 20 rpm. while, the minimum seeding rate of 2.30 kg/fad., was obtained at metering-device speed of 60 rpm. The maximum plant-emergency of 93.6% was obtained at forward speed of 1.82 km/hr. While, the minimum plant-emergence of 82.3% was obtained at forward speed of 4.79 km/hr. By increasing forward speed from 1.82 to 4. 79 km/hr., the total cropyield decreased from 3200 to 2400 kg/fad. Also the minimum production-cost of 26 LE/ton was obtained using forward speed of 4. 79 km/hr.
