1.1 IRRIGATION & ITS IMPORTANCE:
Irrigation is defined as “Artificially supplying & systematically dividing of water for agr ic ult ure & ho rt ic ult ure in o rder to ob ta in highe r or q ua lita t ive ly bet ter production”(After Eijkelkamp Agrisearch Equipment). Water is essential to plant growth & for millenniums. Successful farmers have used different methods to apply water to their crops. This artificial addition of water is called irrigation. Irrigation is essentially the artificial application of water to overcome deficiencies in rainfall for growing crops (Cantor, 1967). Irrigation is a basic determinant of agriculture because its inadequacies are the most powerful constraints on the increase of agricultural production. In traditional agriculture, irrigation was recognized for its protective role of insurance against the vagaries of rainfall & drought. But now, adoption of high yielding varieties, chemical fertilization & multiple cropping highly used controlled irrigation for increasing productivity.
Importance of Irrigation:
In the next 35 to 45 years world food production will need to double to meet the demands of increased population. Ninety percent of this increased food production will have to come from existing lands & seventy percent of this increased food production will have to come from irrigated land. Without irrigation farming is very limited & if the rainfall decreases to less than 30cm, agriculture becomes impossible without irrigation (King, 1953). It increases crop yield. It protects from famine. It helps to cultivate superior crops with the water supply as per need of the crops. Ultimately it helps in economic development. Irrigation water improves water conditions in the soil, increases the water content of plant fibers, dissolves nutrients & makes them available to plants. Irrigation affects temperature conditions by regulating the temperature of the surface layer of the soil & the ground layer of the air & also makes possible control of the growth & development of plants & improvement of the quality of the harvest. In fruit & berry crops that receive optimum quantities of moisture, the sugar content of the fruit increases & in oil crops the fat content in the seeds is greater. For rice & wheat) with supplementary nitrogen feeding), the protein content in the grain increases & for cotton the quality of the fiber is improved.
Answer:
Explanation:
Irrigation is the term used to describe the artificial process of watering plants to aid in their growth. Ponds, lakes, rivers, tube wells, and wells are the primary sources of irrigation. Irrigation is the process of regularly delivering water to the land via canals and other artificial ways in order to promote agricultural growth and preserve the landscape during times of lower than usual rainfall.
Importance of Irrigation
To fulfil the demands of the growing population, the world's food output must quadruple during the next 35 to 45 years. Ninety percent of this enhanced food production must come from already-existing areas, and seventy percent of it must come from irrigated land. Agriculture is impossible without irrigation if rainfall falls to less than 30 cm, which is very limited cultivation (King, 1953). Crop yield rises as a result. It offers famine protection. With the water supply being adjusted to the crops' needs, it helps to develop superior crops. In the end, it promotes economic growth. Aside from enhancing soil water conditions and increasing the water content of plant fibres, irrigation water also dissolves nutrients and makes them available to plants.The temperature of the soil's surface layer and the ground layer of the air are controlled by irrigation, which also allows for the management of plant growth and development and an improvement in the quality of the harvest. Fruit and berry crops that receive the right amount of moisture have higher sugar content, and oil crops have higher seed fat content. With additional nitrogen feeding, the protein content of the grains improves in rice and wheat, and the quality of the fibre is improved in cotton.
