Abstract
The present investigation titled “Effect of drip irrigation and nitrogen fertigation on growth parameters of fennel” was conducted during the Rabi season for two years 2021-22 and 2022-23 at Research Farm of the Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana. The experiment consists of two varieties viz., V1: Hisar Swarup, V2: HF 143, four Irrigation scheduling viz., I1: 0.6 IW/CPE (Irrigation water/ Cumulative pan evapotranspiration) through drip, I2: 0.8 IW/CPE through drip, I3: 1.0 IW/CPE through drip, I4: 1.2 IW/CPE through drip, three nitrogen levels viz., N1: 20 kg/ha, N2: 35 kg/ha, N3: 50 kg/ha. During field preparation, half a dose of nitrogen as urea and a full dose of phosphorus in the form of SSP were applied as a basal dosage. Necessary measurements and plant protection measures were implemented following the recommended package practice of HAU to manage insect pests and diseases. There is a increase in growth parameters viz., plant height, number of primary and secondary branches, days to 50% maturity and flowering when drip irrigation and nitrogen levels increases. The study concluded that variety HF-143 with irrigation scheduling I3 and nitrogen dose N3 were found superior over other treatments for better growth parameters.
