| dc.description.abstract | Raised beds are formed by moving soil from the furrows to the area of the bed, thus raising its surface level. Bed forming attachment to mini-tillers was designed, fabricated and evaluated. To reduce the drudgery and time-consuming manual forming of raised beds especially in the highland vegetable producing regions of Norther Luzon. The attachment was conceptialized as an added feature for mini-tiller, is the problem. Fabrication was done at the College of Engineering Shop, CLSU and was evaluated at an open field at Bagong Sikat, Science City of Muñoz, Nueva Ecija. The single factor experiment laid out in Completely Randomized Design (CRD) with three levels (0.18m/s, 0.19 m/s, 20 m/s) and three replications was utilized. The effective working width, fuel consumption rate, mean bed height, time of operation, field capacity and field efficiency were analyzed using Analysis of Variance (ANOVA) and means were compared using Latest Significant Difference (LSD). Result of the field test showed the attachment was able to form beds the average effective width of 72.60 cm and mean bed height of 14.68 cm. Furthermore, field performance test showed that the average field efficiency and capacity obtained was 89.97% and 0.049 ha/hr. Cost analysis of the device showed that a total investment of Php 5,050.00, yield an annual total fixed costs of Php 1,212.00/yr and a break-even area of 0.4 ha/yr at a custom rate of Php 5,000.00/ha. | |
