Detailed Explanation
- The objective of protective irrigation is to protect the crops from adverse effects of soil.
- Productive irrigation is meant to provide sufficient soil moisture in the cropping season to achieve high productivity.
- In such irrigation the water input per unit area of cultivated land is higher than protective irrigation.
- Rainfed farming is further classified on the basis of adequacy of soil moisture during cropping season into dryland and wetland farming. In India, the dryland farming is largely confined to the regions having annual rainfall less than 75 cm. These regions grow hardy and drought resistant crops such as ragi, bajra, moong, gram and guar (fodder crops) and practise various measures of soil moisture conservation and rain water harvesting.
