Abstract
Mini tractor (18 hp) operated single row vegetable transplanter was developed for Tomato and Brinjal crop transplanting. A simple rotating magazine type metering system was attached to the transplanter. The performance evaluation was done in was 20× 10 m at 1.0, 1.5 and 2.5 km/h. But at low speed i.e 1.0 km/h the results were in acceptable range. The main parameters of the developed transplanter were planting angle and missing percentage. Planting angle was 3.02 and 2.45º, similarly missing percentage was 9.5 and 8.78 % for Tomato and Brinjal respectively. The field-capacity and transplanting-efficiency were obtained 0.05 ha h-1 and 83.3% respectively. Breakeven area obtained as 0.42 ha and payback period was 44.71 h.
Keywords: Low horse power, missing percentage, planting angle, rotating magazine type and transplanting
