ECONOMIC ANALYSIS:
The analysis reveals that, among the different
treatments, CB-RSG alone gave the highest gross
benefit-cost ratio of 3.11. This simply means that for
every peso investment, P2.11 goes back to the farmer as
profit.
In
combinations with inorganic fertilizers such as 1/3 M-99
+ CB-RSG (T4), ½ M-99 + CB-RSG (T6) and M-99 + CB-RSG
(T8), the gross benefit-cost ratios obtained were 2.73,
2.58 and 2.40, respectively. The M-99 recommendation for
dry season (T2) gave a benefit-cost ration of 2.63 while
the lowest ration of 1.50 was obtained form the untreated
plants.
CONCLUSION AND RECOMMENDATION:
The CB-RSG, with a guaranteed analysis of 1.20% N, 0.08 %
available P2)5 and 3.31% soluble K2), together with 82.3
mg Al, 0.086 mg B, 18.6 mg Ca, 3.41 ppm Cu, 21.4 mg Fe,
31.1 Mg, 0.60 mg Mn, trace amount of Mo, 0.60 mg Si, 1.45
mg Na, 0.70 mg S, and 1.70 ppm Zn, could be substitute
and/or a supplement to the conventionally soil-applied
fertilizer commonly referred to by farmers as the
Masagana-99 (M-99, dry season). The recommended 90-30-30
for dry season could be reduced to 30-10-10. This reduced
amount of inorganic fertilizer will be supplemented by
soil drenching before transplanting at the rate of 10 cc
per 16 liter of water (1 knapsack-load), then followed by
6 sprayings after 10 days at the rated of 3 cc per
knapsack-load every 7 days and 2 more sprayings
thereafter at the same rate in 2 week interval. It will
require 25 knapsack sprayer refills to completely cover a
hectare.
