Divina C. Jose
The project was conducted in BPI-Buguias Seedfarm and BPI-Baguio experimental farm from December 2013 to March 2016 to evaluate the effects of organic fertilizers and mulching materials on selected highland vegetables; identify the best or appropriate organic fertilizer and mulching material; determine their effects on the soil; and compare the profitability of using organic fertilizers and mulching materials for selected highland vegetables.
On organic fertilizers, chicken manure (4, 5 and 6 tons/ha), mushroom compost (6, 8 and 10 tons/ha), horse manure (6, 8 and 10 tons/ha) and vermicompost (8, 10 and 12 tons/ha) were applied on lettuce, broccoli and carrot, respectively, one week before transplanting/sowing. The application of chicken manure on the test crops enhanced the production of heaviest lettuce heads, broccoli curds
The application of chicken manure on lettuce, broccoli and carrot noted the highest return on investment of 152.19, 179.42 and 148.92 %, respectively followed by the application of mushroom compost on lettuce and
