Guava is a well-known fruit throughout the Dominican Republic because it easily adapts to different climate conditions, soil, altitude above sea level, natural enemies, etc. The guavas that existed in the country until a few years ago, were not very commercial. Some, because of their small size, abundant seeds, and a small mesocarp; and others because of their flavor, texture, low Brix, and hardness, making their acceptance by the population impossible. The untiring work carried out by Taiwanese technicians, in all aspects of agriculture and especially in fruit growing, has provided the country with the necessary technology for the commercial exploitation of different fruit trees and shrubs, some of which are exotic and have a great potential for export.
The Technical Mission of Taiwan introduced the Pearl, Crystal, and Thailand guava varieties to the nation. The fruits of these three varieties enjoy very good acceptance by the population, having a good demand in supermarkets, grocery stores, and street vendors. The Pearl variety has a medium size of about 280 grams (10 ounces), and it has a bright green color at the time of harvest. Its pulp is white and it is quite sweet, ranging from 10% to 18% Brix degrees. This variety is preferred by the majority of consumers and, as is natural, it is the most sown by the producers.
The Cristal variety is larger than the Pearl variety, weighing about 400 grams (14 ounces). It has a Brix degree of 7% to 12% so it is less sweet than the Pearl variety. It's pulp is white and the fruit is round and bright green at the time of harvest.
The Thailand variety produces fruits of greater size, as it can weigh 500 grams (17.8 ounces). This variety has 7 to 10% Brix degrees, which means that it is not as sweet as the previous varieties. Its pulp is white and the fruit is bright green at the time of harvest.
The demand for this fruit in all of the country's towns and cities is stimulating agricultural producers to plant this fruit, which has a very pleasant flavor and a high nutritional content. At the moment producers must work to supply the national market, which is growing rapidly, and then stimulate production for export, where there is also an unmet demand.
In addition, producers will receive the advice of specialized technicians, who were trained in all of the crop's phases by the Taiwanese specialists. Guava is always in production and if producers use good management regarding pruning, fertilization, irrigation, and pest control, they will always have good quality fruits and achieve good prices in the market.
