Six months ago I bought the books
Tropical Fruits (Crop Production Science in Horticulture) , Volumes 1 & 2, by Robert E. Paull and Odilio Duarte and have been very pleased. A little pricey, but excellent reading.
My Amazon reviews:
Volume 1: Excellent Coverage of Some Major Fruit Crops 5.0 out of 5 stars
Great coverage of cultivation and propagation methods, climate requirements and post-harvest handling for some major crops. Plenty of graphs, charts and tables supplement the clearly-written and well-organized text. This book is a great reference resource for backyard growers and small farmers. However, coverage in this book is limited to the most important fruits that grow in most tropical climates. Volume 2, Tropical Fruits (Crop Production Science in Horticulture) provides coverage of more minor fruits. There are even more minor fruits that receive no coverage in either volume. Maybe there'll be a volume 3 some day.
This book is a little pricey, but has more depth than the free version of Julia Morton's book Fruits of Warm Climates that is available free online.

An exceptionally thorough description of cultivation methods for many tropical fruits. Each chapter on a fruit or fruit family describes the soil and climate requirements, its growth and fruiting habits, and cultural practices. The sections on cultural practices provide detailed information on propagation, planting, irrigation, pruning and post-harvest handling of the fruit. The end uses of the fruits are also described. All this information is presented in an easy-to-read format with sufficient tables, charts, drawings and photos that make it a pleasure to browse.
The chapters are (1) Annonas: Soursop and Rollinia, (2) Breadfruit, Jackfruit, Chempedak and Marang, (3) Carambola and Bilimbi, (4) Durian, (5) Guava, (6) Mangosteen, (7) Rambutan and Pulusan, (8)Passionfruit and Giant Passionfruit, (9) Palms, (10) Other African Fruit: Tamarind, Marula and Ackee, (11) Other Tropical Asian and Pacific Fruit (Langsat, Duku, Santol, Wax Apple, Pummelo, and Ambarella), and (12) American Fruit (Mamey Sapote, Sapodilla, Pitaya, Acerola, and Naranjilla).
This is book, and its companion book, Tropical Fruits, Volume 1 (Crop Production Science in Horticulture), are my primary reference sources for my fruit farming.
