Nutrient Extraction by Different Avocado Cultivars
The avocado producing area of Mexico includes several regions and cultivars. This report presents new information on the differences in fresh weight, dry weight, and fruit nutrient uptake in four avocado commercial cultivars.
Research was conducted in “Booth-8”, “Choquette”, “Hall” and “Hass” avocado cultivars, grown at four commercial orchards. Five avocado fruits (physiological ripe and of dominant size) were harvested from 20 trees of each cultivar. A total of 100 fruits per cultivar were analyzed. Chemical analyses were perform by a certified commercial laboratory using standard methods approved by the Mexican Soil Science Society.
When a comparison of the total fresh weight of fruit is made, “Hass” avocado (239 g) could be considered to be a small fruit compared to the “Booth-7” (405 g), “Hall” (525 g) and “Choquette” (879 g) cultivars, (Fig. 1). However, if the comparison is based upon dry matter content, the “Hass” fruit has the highest content (23.2%), compared to all other cultivars (Fig. 2).
