Response of fennel (Foeniculum vulgare mill) to irrigation and fertility levels under north gujarat condition

A field experiment was conducted in loamy sand soil to observe the effect of irrigations (0.6, 0.8 and 1.0 1W/CPE ratios) under varying levels of nitrogen (60, 90 and 120 kg/ha) and phosphorus (30, 45 and 60 kg/ha) on yield, consumptive use of water and water use efficiency. Significant increase in seed yield was recorded up to 0.80 1W/CPE ratio, whereas consumptive use of water increased significantly up to 1.0 1W/CPE ratio. Water use efficiency and water expense efficiencywere maximum under 0.8 1W/CPE ratio. Seed yield and consumptive use of water increased with increase in nitrogen levels, but significant increase was observed up to 90 kg N/ha. Maximum water use efficiency and water expense efficiency were obtained with application of 120 kg N/ha. Application of phosphorus was unable to produced any remarkable effect on yield and consumptive use of water.
