ABSTRACT
The nutmeg fruits are harvested on time and at the proper stage of maturity in order to maintain their nutrients level as well as attaining desirable quality. Presently, the method adopted for harvesting nutmeg in Konkan region is by manual means i.e. by hand picking, by shaking the tree branches or by using bamboo stick having a curved hook. It was therefore, necessary to develop harvesting system with simple design, easy for operation, low cost but with higher working efficiency. In view of the present investigation was carried out at Department of Farm Machinery and Power, College of Agricultural Engineering and Technology, DBSKKV, Dapoli. The system consists of fruit harvester, telescopic pole, harvesting platform, and fruit collecting basket. The operator locate the matured fruits in V-shaped picker hook and fruit was gently pulled with little force and collect the harvested fruits in collecting net then to fruit collecting basket. The harvested fruits are transported from field to storage house or further process. The operator can increase or decrease the length of telescopic pole as per requirement. Ergonomic evaluation has taken in to the study and found that, the average work pulse value was found to be 18.55 (±8.42) bpm. The average oxygen consumption was found to be 0.70 (±0.28) lit/min. Overall discomfort rating was observed as 4.5 which comes under less than moderate discomfort. The average energy expenditure value was found to be 14.78 (±5.83) kJ/min which comes under moderate energy grade of work. Body part discomfort score was found to be 15.67. Average harvesting capacity of fruit harvester was found to be 8.15 (±0.63) kg/h.
