Water though valuable, is one of the hard to find resources required for food materials production inside our country. Every care ought to be taken to employ this resource efficiently. Selection of the right method of irrigation based on crop and garden soil type is actually a prerequisite intended for efficient using water. It also helps in improving and sustaining soil productivity in the long run. Various methods of irrigation have been thoroughly discussed from this booklet. Character types of an efficient method of water sources, factors affecting the suitability of an water sources method and cultural techniques for raising water work with efficiency have also been briefly outlined.
Dr . T. T. Chandy, Agricultural & Environmental Education,
Water is an important component of the herb body. Crops need drinking water to carry on distinct physiological operations essential to their very own growth and development. A lot of water from plant person is wasted throughout the process of transpiration. Therefore , to compensate this lack of water, absorption of drinking water from soil is an important sensation. Soil gets water mainly from two sources viz. precipitation and irrigation.
Hence, irrigation is a procedure, other than organic precipitation, which supplies water to crops, orchards, grass, or any type of other grown. plants. Inside the wetter regions of the world where rainfed cultivation is used, the farmer's activities consist of selecting suitable land, preparing the ground for fostering; sowing, tending and cropping the plants. Natural rainfall provides the water needed. But in many other spots otherwise good for fostering, natural rain fall does not provide all the water needed and, as such, irrigation of plants is required to make up this deficiency.
Techniques followed for carrying normal water from its origin to the plant are called strategies or settings of application. These are:
1 . flooding -wetting all the land surface;
installment payments on your furrows -wetting only certain a part of ground level;
several. sprinkler -in which the soil is wetted in very similar way since rains; 4. sub-surface irrigation -in which usually surface is definitely wetted very lightly, however the sub ground is completely saturated; and 5. local irrigation -in which water is utilized at each person plant by. a near daily price.
II. Attributes of an Effective Irrigation Method
An efficient method of irrigation should satisfy five major objectives viz. (1) circulation of water uniformly within the field according to plants need, (2) storage of maximum small percentage of water in the main zone for plant employ, (3) harvest growth really should not be adversely afflicted, (4) dirt transport or loss is definitely negligible, and (5) the technique used is usually economically sound and adoptable in the farm.
3. Factors Affecting Suitability of Irrigation Approach
The selection of the right irrigation means for a particular plantation location is determined by the following factors.
1 . Garden soil
Textural, crusting, cracking and infiltration characteristics of surface ground; nature and depth of relatively impermeable layers in sub-soil, in the event that any; water storage capacity of root sector; nature and extent of land slope; size of field; surface draining; nature and extent of salts in surface and sub-soil are the salient dirt factors impacting on between of your irrigation method. 2 . Water
Nature of water supply (continuous or rational). source (pump or...
