Extracted text: In a farmland irrigated by a system of pumps from wells, the area irrigated is 50 hectares. Water pumped from wells is conveyed through a canal to the farms. Efficiency of water conveyance is 85% and pumps work at 12 ohours/day. Available moisture holding capacity of the soil is 20cm per metre depth and the average root zone depth is 1m.Water application efficiency is 80%. Irrigation is started when moisture extraction level of 50% of available moisture is reached. Peak rate of moisture use by plants is 5mm. Calculate the irrigation period in days and total pumping capacity required in 29. litres/minute.
