(a) Coffee

The world's cher coffee-producing areas include the state of Sao Paulo in Brazil which produces 50% of the total, the Central American states and islands (Guatemalo, San Salvador, Jamica, Mexico and Venezuela), Java, and Kenya- in Africa. The main importers are the U.S.A Germany, France, Belgium, the Netherlandss and Austria.

Coffee L a provuce un tropical nighlands, It gives the highest quality of yield at about 4500 feet where the temperature averages about 70°F. Annual reinfall of 40" to 70" is most favourable, Rainfall should be heaviest during the flowering and maturing season and relatively slight at harvest time. There must be no frost, which is injurious to the plant. It requires a Jeep, well-drained soil; a volcanic soil is best. During its early growth, the plant must be sheltered from the direct rays of the sun. Snade 1s usually provided by planting crops such as bananas and maize between rows of coffee plante, A large supply of cheap labour should be available. for picking and processing.

to vary from 15 inches in the more huadd tropical areas to about 20 inches in north-western India. Supply of water must be wall controlled so that the paddy fields can be flooded during the early period of growth. The amount of water needed increases from planting time to the middle of the. vegetative period and decreases thereafter, A permeable rich alluvial soil is ideal for retaining the moisture, but the subsoil must de impermeable so as to prevent the water draining - away too readily. Fairly lavel lands are required so as to avoid over-great expenditures for terracing. Requirement of light if quite important for rice. In sub-tropical and temperate regions, the Jong summer days favour growth, and partly as a result of this, yields are high in Japan, Italy and Spain. In tropical regions, during the rainy season, however, frequent cloudiness may result in low rice yields which prevail in parts of monsoon Asia. A large supply of labour is necessary for: doing work in the padi fields..

The only other notable producing countries apart from those mentioned above are Nigeria, Congo and Brazil.

U.S.A. is the biggest consumer or rubber and it takes in more than half of the total production of south-east Asia. Japan, Great Britain and West" Germany are the other important importers. The world rubber market is subject to periodic flucutations. What makes the situation more complicated is the competition that comes from synthetic rubber in the recent years. 1

Rubber plantations are confined equatorial climate. For optimum growth and yield. temperatures with a mean minimum of 75°F ari required. The mean maximum should not exceed 95°F as high temperatures, unless accompanied by high humidity, cause too rapid drying out with resultant cessation of latex flow. The annual rainfall should exceed 70" and be evenly distributed: throughout the year, Rubber plantations also need

Deep alluvial soils are preferable though relatively shallow soils may be treated with artificial fertilizers. The area should also be free from fungus and bacterial diseases, Lastly, an adequate supply of labour is essential for the daily collecting of latex and ita preparation.
