This report supports the university's advocacy to follow organic farming practices. Similarly, Cat-ag (2007) recommended not applying liquid biofertilizer to spoon cabbage or bok choy if the soil has a pH of 6.34, 3.5% organic matter, 140 ppm phosphorus and 1,510 ppm potassium as the experimental area of the research. . Similarly, PCARRD (1979) pointed out that organic matter improves soil structure, increasing the soil's ability to retain water and provide aeration.
A week later, the application of the liquid biofertilizer (X-Tekh Micro) and concentrated mineral drops (Amazing Harvest) began. Except for this treatment plot, the other treatment plots were maintained without the use of synthetic chemicals. Ten sample plants per plot were measured randomly with a tape measure from the base of the plant to the surface of the curd.
The curd samples were pressed and the liquid was placed in the main prism of the refractometer covered with the daylight plate and the reading was recorded. As presented in Table 1, plants applied only with alnus compost significantly exceeded the curd diameter produced by the rest of the treatments with similar curd diameters. Except for plants applied with alnus compost, the rest of the treatments produced curds of almost similar diameter.
The application of alnus compost alone and farmers' practices promoted the production of a similar stem diameter that was significantly larger compared to the rest of the treatments.

There were no significant differences on the total yield harvested from the broccoli applied with different organic fertilizer materials as presented in Table 3. This result may be due to the presence of high nutrient elements in the soil before planting as shown by the soil analysis in which the organic matter content was 10.00%, phosphorus of 380 ppm and the potassium was 1,100 ppm. Plants applied with alnus compost alone produced higher marketable curd followed by those applied with alnus compost + liquid bio-fertilizer, no application of fertilizer, farmer practice, plant size and the lowest was harvested from plants applied with alnus compost + concentrated mineral drops, but the differences were not significant (Table 4). Weight of marketable and non-marketable curds of plants applied with the different organic fertilizers.
However, plants not supplied with manure (control) had slightly heavier non-marketable curds due to abnormalities, and plants supplied with alder compost alone produced the lowest non-marketable curds. But curds from plants applied with liquid biofertilizer weighed heavier followed by application of alder compost alone, no fer-. 21 ilizer application, farmer practices, plant mate and the lowest weight of curd was produced by plants applied with concentrated mineral drops.
The shelf life of broccoli curd treated with different organic fertilizers is shown in Table 7 and Figure 3. Plants treated with concentrated mineral drops achieved a longer shelf life, but did not differ significantly from the other treatments. It follows that the curd shelf life was the same at four days, except that the plants applied with CMD, which had a mean value of 4.67 days, were slightly longer than the other treatment.
This means that there are five types of glucosinolate compounds in the analysis of broccoli and that plants treated with alnus compost alone had the highest values of GI1 and GI2 and the lowest values of GI3, GI4 and GI5. In contrast, plants applied with alnus compost, then supplemented with liquid biofertilizer (X-Tekh), produced curds with the highest concentration of glucosinolates in GI5. Peak area (in MAU) of five glucosinolate compounds observed from the chromatogram of different curd samples applied with different organic fertilizers.
The very small differences in the marketable yield between the plants applied with alnus compost alone and with the application of alnus compost plus the additions of bio-liquid fertilizer of 0.19 kg per plot when projected on a hectare basis, would mean 380 kg more yield or P amount. 38,000.00 more sales, but the application of alnus compost which is then supplemented with bio-liquid fertilizer will still earn net income of P 13,200.00 due to lower expenses in fertilizer. The shelf life of curds treated with concentrated mineral drops was slightly longer than the other treatments which had an average of 4.0 which was considered poor quality in the refractive index of similar results;. In terms of profitability, the application of alnus compost + liquid bio-fertilizer achieved the highest return on expenditure of P1.43 for each peso spent, followed by the application of alnus compost alone and without fertilizer application.
Based on the results presented and discussed, it appears that among the treatments, the application of alnus compost alone promotes shorter plants with wider stem diameter and curd resulting in slightly higher yield with a return on expenditure of P1.34 per every peso spent compared. in the second rank where the plants were applied with alnus compost supplemented with liquid biofertilizer P1.22 containing the highest glucosinolate composition. It is then recommended that when the soil contains 10% organic matter, 380 ppm phosphorus and 1100 ppm potassium, alnus compost alone would be sufficient. Alternatively, the application of alnus compost supplemented with liquid biofertilizer provides higher return on costs also with the highest content of glucosinolate compounds.
