A LITTLE ABOUT MANGOS
Mangos is native to southern Asia, especially Burma and eastern India. It spread early on to Malaya, eastern Asia and eastern Africa. Mangos were introduced to California (Santa Barbara) in 1880. Mangos exists in two races, one from India and the other from the Philippines and Southeast Asia. Mangos from Indian don’t grow well in humidity and get mildew easily. The Philippine Mangos tolerate alot of moisture, has pale green or red new growth and resists mildew. Philippines types from Mexico have proven to be the hardiest mangos in California.
Mangos require a frost-free climate. Flowers and small fruits can be killed if temperatures drop below 40° F, even for a short period. Young trees may be damaged if the temperature drops below 30° F, but older trees are able to survive very short periods of temperatures as low as 25° F. The mango must have warm, dry weather to set fruit. In southern California the best locations are in the foothills, away from immediate marine influence. Mangos luxuriate in summer heat and resent cool summer fog. Wet, humid weather makes the Mangos go bad.
“Soil: Mangos will grow in almost any well-drained soil whether sandy, loam or clay, but avoid heavy, wet soils. A pH between 5.5 and 7.5 is preferred. They are somewhat tolerant of alkalinity. For good growth, mangos needs a deep soil to accommodate their extensive root systems.
Irrigation: Irrigation should start when the weather warms meaning February in the desert and April at the coast. Irrigation may be discontinued when rains are sufficient to maintain soil moisture. Watering is then increased after one to two months to initiate a new bloom and growth cycle.
Frost Protection: During the first two years, the trees should be given some protection such as an overhead cover during any frost threat. Once the tree is 3 to 4 feet high, overhead protection is difficult but still worthwhile, especially if an unusual cold snap is predicted. Frost damage can also be avoided by erecting an overhead lath shelter, orchard heating, placing lights under the canopy, or using foam or straw trunk wraps.”
Fruit Harvest:When the first fruit shows color on tree, all of that size fruit or larger may be removed. They tell you to repeat when remaining fruit colors. They also tell us to not store below 50° F.The fruit ripens best if placed stem end down in trays at room temperature and covered with a dampened cloth to avoid shriveling. Mangos ripen in June from January bloom in interior California, and October from April bloom on the coast. They say that “less time is required to mature greenhouse fruit.”
Pests and Diseases: Scale, mealybugs and mites are frequent pests in the greenhouse and orchard. In the greenhouse, thrips often turn leaves rusty brown. Malathion is the conventional spray for insect pests but sulfur does work on mites. Gophers are attracted to the roots of the Mango plant. Sodium bicarbonate and fungicide sprays are also effective.

Climate
“The mango is naturally adapted to tropical lowlands between 25∞N and 25∞S of the Equator and up to elevations of 3,000 ft (915 m). It is grown as a dooryard tree at slightly cooler altitudes but is apt to suffer cold damage. The amount of rainfall is not as critical as when it occurs. The best climate for mango has rainfall of 30 to 100 in (75-250 cm) in the four summer months (June to September) followed by 8 months of dry season. This crop is well suited to irrigated regions bordering the desert frontier in Egypt. Nevertheless, the tree flourishes in southern Florida’s approximately 5 months of intermittent, scattered rains (October to February), 3 months of drought (usually March to May) and 4 months of frequently heavy rains (June to September).
Rain, heavy dews or fog during the blooming season (November to March in Florida) are deleterious, stimulating tree growth but interfering with flower production and encouraging fungus diseases of the inflorescence and fruit. In Queensland, dry areas with rainfall of 40 in (100 cm), 75% of which occurs from January to March, are favored for mango growing because vegetative growth is inhibited and the fruits are well exposed to the sun from August to December, become well colored, and are relatively free of disease. Strong winds during the fruiting season cause many fruits to fall prematurely.
Soil
The mango tree is not too particular as to soil type, providing it has good drainage. Rich, deep loam certainly contributes to maximum growth, but if the soil is too rich and moist and too well fertilized, the tree will respond vegetatively but will be deficient in flowering and fruiting. The mango performs very well in sand, gravel, and even oolitic limestone (as in southern Florida and the Bahamas)
A polyembryonic seedling, ‘No. 13-1′, introduced into Israel from Egypt in 1931, has been tested since the early 1960′s in various regions of the country for tolerance of calcareous soils and saline conditions. It has done so well in sand with a medium (15%) lime content and highly saline irrigation water (over 600 ppm) that it has been adopted as the standard rootstock in commercial plantings in salty, limestone districts of Israel. Where the lime content is above 30%, iron chelates are added.”

Q1. How many imports of Mangos increased from 1981 to 1990?
A1. In one decade, US imports of fresh mangos increased from 42.4 million llb in 1981 to 139.8 million llb in 1990.
Q2. Do Mangos contain high levels of antioxidants like Grape and Pomergrante Juice do?
A2. Yes. Vitamin C is an antioxidant and you can get that from Mangos which is loaded with Vitamin A,C, and D. Other antioxidant that has Vitamin C are Citrus, broccoli, etc. But Mangos are very low in Carbohydrates.
Q3. Are Mangos good for the digestive system?
A3. Yes it is very good for the digesive system and it is very valuable to combat acidity and poor digestion. Mango is a rich source of Vitamin A (beta-carotene), E and Selenium which help to protect against heart disease and other ailments.

Mangos are very well adapted to tropical and subtropical climates. It thrives well in almost al the regions of the country from sea level to an altitude of 600 m. The ideal temperature range for mango is 2400 – 3000 C during the growing season, along with high humidity A rainfall range 890 – 1,015mm in a year is considered as ideal for growing mangos in the Philipines. When the weather in the Philipines is foggy and coudy which is in November to February it results in poor setting of Mangos and brings insects and disease that harms the Mangos and fruits in general. In the Philipines Mangos grow well on wide vareity of soils such asa latertic, alluvial, sandy loam and sandy. The loamy, alluvial, ewll-drained aerated and deep soils are a rich oraganic matter. Mango requires soil having good internal drainage, but is not particular as to soil type. Trees can tolerate minor flooding, but have low tolerance for salts, boron and lawn herbicides. Because of its extreme sensitivity to cold, mango should be planted in the most protected site in the yard within 8 to 12 feet of the south or east side of the house.
I decided to do a project on Mangos casue when i was little i ate so much Mangos and now im so interested in it. I then decided to make it more specific and do it in the Philipines cause im from the Philipines and i always wanted to learn about the agriculture in th Philipines. So in the end im doing my project on the the climate change of a Mango in the Philipines and see how the affects the Mangos. I decided to do a diagram on a a box and on each side show how the the climate affect the Mangos.

No rain means no fruits, no rice, and no harvest of any kind. In the Philippines part of the year is almost only sunny – the remaining part is sometimes mostly rain, storm and dark clouds, depending on where in the Philippine islands you are during rainy season.
Rainy season is when all the fruits start to grow. In Manila, Philippines it’s always almost very hot and every now and then it’s great to have rain so crops such as Mangos, Rice and other fruits and crops can grow for everyone to enjoy during dinner time. Without rain the Mango trees wouldn’t grow and have all the nice Mangos sprouting out and waiting for the sun to help them get juicy and ripped. If there is too much precipitation the Mangos will have a hard time ripening because they need the sun. This happens all the time during rainy season in the Manila, Philippines. Mangos are usually all yellow and green and never become red and orange until the sun comes out. Rainy season means it never stops raining for a month and a half there for when people are harvesting it’s a good idea to collect all your crops and plant new ones befor the rain comes so it won’t get over rained on because it could cause the fruits to rot.
Dry season is from March to May with it being the hottest. It gets up to 38C. The north-western part of the country during this period is visited by the monsoon that south-east Asia like the Philipines is well-known for, while the climate on the south-eastern islands is the same during the entire year.
The weather is good in the begging because the sun is important since it helps to ripen the mangos after the rainy season. The dried up Mangos are all tan and very hard. As the hot dry air continues with no rain in site this does not serve the Mangos or any crops well and they begin to get dried out. So if the Mangos aren’t picked or harvested they will be dried up and ruined and not worth selling. Although some of the Mangos that are dried up since Mangos are very nutritious for you and a “Golden Fruit” they made the dry mangos into something eatable which is called Dried Mangos. Dried Mangos are delicious, if you have not tasted them before you should defiantly put it on your “To Do” list.
