Abstract

Weekly and operational labor input requirements were evaluated for experimental production of drip irrigated vegetables at the Fortuna Substation, Juana Díaz, Puerto Rico. The total man-hours per ha required in the plastic mulched plots were 1,964.1, 1,644.9, 1,412.7, 1,561, 1,247, 1,382 for peppers, cabbages, watermelons, cucumbers, snap beans (once-over harvest) and snap beans (multiple harvest), respectively. In the nonmulched plots, the man-hours were 1,899.8, 1,460.5, 1,119, 1,386, 1,247, and 1,387, respectively. Labor input for the tomato crop was 3,021.2, 1,891.2, 2,591.1, 1,467.1 in the plastic-staked, non-plastic-staked, plastic-non- staked, non-plastic-non-staked plots, respectively. Pigeon peas (var. Kaki) required 1,334.9 man-hours per ha; 2-B-Bushy variety required 1,368.9. Trickle irrigation installation and dismantling operations needed 4.1 to 16.1% of total labor input; plastic mulch management required 15.3 to 28.4%. Weeding operation amounted to 12.4 to 27.1% of total labor input compared with 28.4 to 62.6% for harvesting and post harvest operation. Use of plastic mulch reduced labor inputs for weeding operation to less than 4%, depending upon crop type and season.
