A Technical and Economic Analysis on Non-chemical Alternatives towards the Burrowing Nematode (Radopholus similis Cobb, Thorne): A Case Study of EARTH University’s Agribusiness Operation


The objective of this study was to analyze the economical effect of some bio-nematicides on Radopholus similis at EARTHUniversity’s banana plantation. The following seven treatments were evaluated: (1) nematode trapping fungi; (2) DiTera DF®; (3) Savitan®; (4) QL Agri®; (5) a Japanese-style compost called EM-comopost; (6) two applications of a chemical nematicide; and (7) an absolute control. Results showed that the bio-nematicides had lower nematode population than the absolute control with the nematode trapping fungi having statistically significant differences over the other treatments. The chemical control presented the lowest nematode population with no statistically significant differences over the trapping fungi treatment. The functional root and plant growth variables showed no significant differences between treatments. The economical analysis showed that using nematode trapping fungi, chemical nematicide, and QL Agri® gave a profit. Based on the cash flow of evaluated technologies the land expectation value estimated for banana activity was higher than the price of banana land. It indicated that under normal conditions in the banana sector, production is profitable. Other results indicated that profits in banana production are affected by changes in the price of the commercial banana box, production cost, and discount rate. The estimated optimal production cycle was obtained in year tenth, which refers to the year with the highest profits following plantation renewal.

Key words: economical analysis, banana, optimal production, economical efficiency, Radopholus similis, land expectation value.
