Wheat is a very important crop growu in the temperate grassland.

cultivation.

an important wheat producing reg ion and print on it the chief ort handling the export of the commodity.

(c) Name TWO countries which export

a lot of the crop.

(d) Branîne the world trade of wheat

WHEAT

(a) Godal conditions:-

Relief and drainage:- It is best to be grown on Land which is well drained and flat enough for: tha Fuse of machinery

Climates-

Temperature1- it needs a growing season of 90 days or more with a temperature of at least 12 0. The July isotherm of 12°C marka: Toughly the extreme northern lin- it of the wheat belt. A bright aunny autumn for harvesting is also desirable.

(b) nanralism It needs an annual rain- fall of 15 to 35" Some of it must fall in the growing season order to swell the grain before reaping.

Joil:- Moderata

atiff Joam or clayey Boil will be good for the crop .g. the "Black Soils" of the Suropean Steppe and the America Prairie.

Labouri- Not muon labour is needed as

mont of the work is done by machinery.

WHEAT PRODUCING AREAS IN AUSTRALIA

(a)

Canada : 2) Australia

In the world trade of this com modity, Canade plays an important part. Each year is produces more wheat than its small population can consume. Thua a large quantity ia exported making Canada the gre ateat exporter. Countries from the Southern continenta such as Australia and Argentina also expo-. rt wheat for the same reason, Two former important exporters, Hussia, and U.S.A., now export much less because of their increasing population.

From these exporters, wheat goes mainly to Western Europe (United King- doms

Germany, Denmark, Belgium) which is another important producing region. They important wheat becauön of the daw

nae pupusavion and much of the land has been devoted to industrial use. Wheat also goes to China, India and Pakistant to feed their huge population thought themselves are also quite large producers.

II) Compare and contrast the productr ion of sugar-cane and sugar beet. under the following headingas.

a) conditions of growth (b) methods of cultivation, and (c) importance in world trade

a) Conditions of growth.

Sugar-cane de a tropical gré as while sugar beet grows in the cool:tem perate zone. For optimum growth, cane requires a hot wet climate with a rainfall of 60" or ita equivalent in irrigation and constant high temperature of 20-25

Beet, on the other hudy

where tha Bummer around 16-20°C and the mositure condition is moderate. For both, toward the

the end of the growing seasons, weather should be dry so as to en aura a higher sugar content.

Labour and soil requirements.

are of paramount importance to both cane and best, The successful: cul- tivation both depends on a reliable supply. of cheap labour thought the demand is more acute on boet lands." Sugar-cane-does-best on loamy, slightly alkaline soils. In many regions, vast lowlands covered. with alluvial or volcanic soile are prec ferred for sugar-cane, Bset is usually limited to fairly sharply defined areas where Boils are deep, well: aerated, free of stones and: neither to clayey, nor too sandy

Methods of cultivationt-

Sugar-cane is grown on Large plantations which are devoted to the sole production of cane-sugar for large scale exports. It is a perennial crop; the first crop is called the "plant-crop" and ripene S ia 15-24 months; the Bucceeding cr- ops are called "ratoon crops" and " usually are produced at intervala of one year. In the tropical regi- ons with wet and dry season, new cana" is generally planted towards the end of a wet season; during the following dry season, growth diminishes. The main period of vegetative growth will be

P withuring

the second wet season, with the ripening occurring during the sec- ond dry season. Before planting. the soils must be wall ploughen and manured.

Rests are annual crops cultivated oz small boldinge. Usually the plant is grow in Spring and harvested in Autumn. It requires very careful cul- tivation and a great deal of labour for hoeing, lifting, topping and loading. Moreover, unlike the monoculture. syater on Bugar-cane lands, the best plays an important role in rotation agriculture. Other crops benefit from the fertiliz-- era added to the fields. In many reg- ione there is a close relationship with animal industries with sugar-beat cult- ivation and the tops of the beat formed valuable by-producta

(e) Importance in world traderm

On the average, 65% of the world's sugar production consists of "cane augar and 35% of beet sugar Bud up to the present, over 90% of sugar that enters internation trade comes. from sugar plantations in the tropica which are geared to exports to the temperate lands. Best eugar is produced. ́mainly for domestic consumption though there is soma trade between neighbour- ing countries in Europe.
