Effect of Scheduling of Irrigation on Yield of Onion (Allium cepa L.) Irrigated through Micro Sprinkler Irrigation System

The field experiment was conducted to study the effect of different cumulative pan evaporation (CPE) levels i.e. 20mm, 30mm, 40mm, 50mm and 60mm CPE on yield of onion irrigated through micro sprinkler irrigation system. The results indicated that the treatments scheduled at lower CPE(20mm) was the best treatment as it produced highest yield of onion after drying (442.05q/ha) and water use efficiency (955.16kg/ha-cm) which was statistically superior over all other treatments. The consumptive use of water was observed highest (462.80mm) in 20mmCPE and lowest (432.59mm) in 60mmCPE.
