It has now been definitely shown that California avocado production can be increased by the interplanting of two or more varieties (4, 5, 6, 11). Contrary to our earlier conclusions (10), cross-pollination evidently increases avocado fruit-set. The observed average increased set of about 40% may well mean a doubling of the grower's net profit-since fixed costs represent a large proportion of his debits.

FACTORS AFFECTING AVOCADO FRUITFULNESS
It has been said that there are just 3 requirements for a superior commercial avocado: heavy production, heavy production and heavy production. This is, of course, a gross over-simplification. In
REASONS FOR LOW YIELDS OF AVOCADOS
TLDR
The first thing that must be said is that often the authors can only guess at the reason for poor avocado fruit-set and it may not be possible to choose among the different factors that could bring about low yields and point at one as the culprit in a particular case.
Studies on the Bearing Behavior and Yield Composition of the Avocado Tree
TLDR
The major impediment to avocado growing in Japan is low temperature, both winter freezes and flowering period chilling, so it is therefore important to select the warmest locations, and also to breed cultivars with greater cold resistance.
Avocado Flowering 1
The avocado (Persea americana Mill.) has increased in importance over the years in many countries around the world. The United States, Mexico and Brazil lead in world commercial production, while

History and Review of Studies on Cross-Pollination of Avocados
TLDR
If cross-pollination is the answer to more consistent and heavier crops, then a practical method utilizing this phenomenon must be developed.
The Effect of Adjacent Trees of Other Avocado Varieties on Fuerte Fruit
Fruit-set on trees of the Fuerte avocado in relation to distance from trees of the Hass and Topa Topa varieties in a Southern California grove was analyzed. The presence of adjacent trees of a second
Fuerte fruit set as influenced by cross-pollination.
TLDR
No case has yet been brought to light in this state where the provision of cross-pollination has measurably improved either the regularity of bearing or the amount of yield of individual trees or solid plantings of single varieties.
AVOCADO YIELDS INCREASED BY INTERPLANTING DIFFERENT VARIETIES
Statistically significant increases in fruit set, associated with the interplanting of two or more varieties, were observed in avocado groves throughout southern California. Specifically, there was
