    Effect of drip irrigation and nitrogen fertigation on growth, seed yield and quality of fennel (Foeniculum vulgare Mill)
    (CCSHAU, Hisar, 2023-08) Akash; Malik, T. P.
    The field experiment was conducted at Vegetable Research Farm, CCS Haryana Agricultural University, Hisar to study the effect of different level of drip irrigation and nitrogen fertigation on growth of fennel crop during the Rabi season of 2021-22 and 2022-23. The experiment material comprised of two fennel varieties i.e., HF-143 and Hisar Swarup as main plot treatment, four levels of irrigation scheduling viz., I1-0.6 IW/CPE, I2-0.8 IW/CPE, I3-1.0 IW/CPE and I4-1.2 IW/CPE ratio as sub plot treatments and three nitrogen levels i.e., N1-20 kg ha-1, N2-35 kg ha-1 and N3-50 kg ha-1 as sub-sub plot replicated thrice were undertaken using drip fertigation. All the treatment combinations were evaluated under split-split plot design for different growth parameters. The application of irrigation scheduled at 1.2 IW/CPE recorded significantly higher values for growth parameters which was at par with 1.0 IW/CPE i.e., plant height, number of branches per plant and days to 50% flowering minimum at 0.6 IW/CPE over other irrigation scheduling in HF-143 variety. Nitrogen levels @ 50 kg ha-1 recorded significantly maximum plant height, number of branches per plant. Days to 50% flowering was recorded maximum at nitrogen level 20 kg ha-1 in HF-143 variety. From the current study it was concluded that fennel variety i.e. HF-143 was found superior with respect to growth parameter when grown at irrigation scheduling 1.0 IW/CPE and 50 kg/ha of nitrogen level in the western region of Haryana.
