| Abstract | ||||
| A double purpose machine prototype for rice transplanting was developed, locally manufactured, and evaluated in order to overcome numerous problems which restrict the mechanization of rice transplanting in Egypt. The proposed transplanter is 4 rows planting machine, and propelled on three ground wheels to suit small scale farms. It suits both traditional rice seedlings method, and in trays seedling method. To achieve these machine functions, the developed prototype included two seedling platforms: - one of them is fixed to accomplish the traditional seedlings method, while the other is movable to accomplish the in trays seedling method. The developed prototype was provided with two groups of finger nails to suit both tested transplanting methods. Transplanting performances the machine prototype was tested and evaluated versus of the two seedling platform types, and the two nail finger types, it was also tested versus four transplanting depth levels of (2 – 3 – 5 – 7 cm), and three provided human power levels. These performances were determined, and evaluated in terms of: -machine field capacity, machine transplanting efficiency, longitudinal seedlings spacing and total machinery costs. The gained results revealed that: - the maximum field capacity values were 0.29, and 0.283 fed/h, and the highest transplanting efficiency values were 72 and 68 % as the developed prototype was accomplishing the traditional, and in trays seedling methods respectively. The optimum transplanting depth for operating the locally manufactured transplanter was determined as 5 cm for both seedling methods. The cost of rice transplanting operation using the locally manufactured transplanter under the study is estimated about 101.82 L. E/fed compared with 600 L.E/fed for manual transplanting and 247.96 LE/fed for the imported transplanter. | ||||
