Cabbage: Results show that Bokashi applied 20 and 40 days before transplanting (DAT) plus EM-1 applied 0, 20, 40 DAT in combination with fertilizer applied at planting performed statistically similar with the farmer's practice. Height of cabbage plants on farmer's practice plots were taller than other treatments. Significantly lower yield was noted on plants applied with Bokashi or EM-1 alone and the untreated than any other treatments.

Lettuce: Bokashi and EM-1 applied singly or combined did not increase the height of lettuce plants. Plots applied with chicken manure + NPK at recommended rate (farmer's practice) were taller than any other plants in the experiment. However, weight of lettuce heads from plots applied with NPK (1/2RR) + Bokashi and EM-1 was more than the rest of the treatments. This was followed by EM-1 alone. The least number of marketable lettuce heads was recorded in plots applied with chicken manure + NPK at RR. This was due to soft rots, a soil borne disease, that attack the plants.

Potato: Mean height between treatments did not differ statistically. However, plants from plots applied with NPK at RR were the tallest; with a difference of one to two centimeters at 30 DAP. At 60 DAP, the tallest plants were from plots applied with chicken manure + NPK at RR with 5 to 6 cm more than other treatments. Generally, the incidence of wilting caused by Pseudomonas solanacearum in potato was lower on plots applied with Bokashi alone and EM-1 alone than farmer's practice. More excellent tuber sizes were observed in plots applied with Bokashi + EM-1 over the usual farmer's practice, that is, chicken manure + NPK at RR indicated that the product can sufficiently supply the nutrients needed by the crop for better yield production.
