Abstract
|
|
|
|
This study was carried out to develop and investigate integrated mechanization system for culture of carrot. Compared with the conventional hand planting, use of a mechanical planter for pelleted seeds resulted in a saving of planting time by 225 hours. An additional saving of 460 hours was obtained for thinning the seedlings. Besides seeds could be saved by 72%, planting and thinning be done only in 35 hours per ha field when the pelleted seeds were planted with a planter. Work hour reduced by adopting the mechanical planting of pelleted seeds sharply contrasted to that of 720 hours required for hand-planting the thinning hours, resulting in a reduction of labor by more than 95%. SMP followed pelleting tended not only to increase the percentage of seedling emergence in the field but to induce an a day earlier germination.
