Other Major Crops
Sugarcane
Sugarcane is the main
source of sugar and is an important cash crop. It occupies about 1.8 percent of
the total cultivated area in the country. In the past, the area under sugarcane
has been fluctuating between 2 and 2.7 Mha. Uttar Pradesh along accounts for
about 47 per cent of annual production in terms of raw sagar. However, the
production per hectare is the highest in Karnataka by Maharashtra and Andhra
Pradesh.
Medium heavy soils are
best suited for sugarcane. it can also be grown on lighter and heavy soils
provided that there is sufficient irrigation available in the former and
drainage is good in the latter type of soils. In north India, it is cultivated
largely on the loams and clay loams of the Gangetic and other alluviums. In
peninsular India, it is grown on brown on reddish loams, laterites, and black
cotton soils.
Sugarcane grows over a
prolonged period. In north India, planting of sugarcane coincides with the
beginning of warm weather and is completed well before the onset of summer.
Usually, January and February are the best months for planting of sugarcane in
Bihar, February in Uttar Pradesh, and the first fortnight of March in Punjab
and Haryana.
In the case of
sugarcane, the maintenance of optimum soil moisture during al stages of growth
is one the essential requisites for obtaining higher yields. The crops should,
therefore, be grown in area of welldistributed rainfall with assured and
adequate irrigation. The total irrigation requirement of the crop for optimum
yield varies between 200 and 300 cm . Sugarcane ripens around December and its
sugar content continues to rise till about the end of March by which time it is
harvested in north India.
Tea
Tea is a important
beverage and its consumption in the world is more than that of any other
beverage. India and SriLanka are the important tea growing countries. In India,
tea is grown in Assam, West Bengal, Kerala, Karnataka, and Tamil Nadu. Tea is
grown over an area of about 358,000 hectares and about 470 million kilograms of
the product is obtained annually. The tea crop is the most important plantation
crop of India.
The tea plant, in its
natural state, grows into a small or mediumsize tree. In commercial
plantations, it is pruned and trained to form a multibranched low bush.
Appropriate schedule of fertilizer applications is very useful to produce
vigorous vegetative growth of the tea crop. The tea plants are generally raise
din nurseries. About one to one anda half year old nursery seedlings are used for
field plantation. Timely irrigation is essential for the production of good
quality leaves.
Potato
Amongst vegetables,
potato is grown over the largest area (for any single vegetable) int eh world.
In the plains of north India, potato is sown from the middle of September to
the beginning of January. Two successive crops can be raised on the same land.
Potato needs frequent irrigation depending upon the soil and climatic
conditions. Generally, size irrigation a are sufficient.
