The amount of irrigation differs for different crops.” Justify the statement by giving examples.
Answers
Answer:
Every crop requires a certain quantity of water after a certain fixed interval, throughout its period of growth
Explanation:
Example = 1. rice requires about 10cm depth of water at an average interval .
2. wheat requires about 7.5 cm of water after every 28 days.
Example 1: If rice requires about 10cm depth of water at an average interval of about 10 days, and the crop period for rice is 120 days, find out the delta for rice.
Example 1: If rice requires about 10cm depth of water at an average interval of about 10 days, and the crop period for rice is 120 days, find out the delta for rice.Solution: Water is required at an interval of 10 days for a period of 120 days. It evidently means that 12 no. of waterings are required, and each time, 10 cm depth of water is required. Therefore, the total depth of water required.

It evidently means that 12 no. of waterings are required, and each time, 10 cm depth of water is required. Therefore, the total depth of water required. = 12 x10 cm = 120 cm.
