    Effect of irrigation and nitrogen fertigation on growth, seed yield and quality of coriander (Coriandrum sativum L.) varieties
    (CCSHAU, Hisar, 2020-08) Vikram; Malik, T.P.
    The present study was carried out at Vegetable Research Farm and in the laboratories of the Department of Seed Science and Technology, CCS Haryana Agricultural University, Hisar to study the effect of irrigation and nitrogen fertigation on growth, seed yield and quality of coriander (Coriandrum sativum L.) varieties. The material comprised of three coriander varieties viz., V1- Hisar Bhumit, V2- Hisar Anand and V3- Hisar Sugandh as main plot, four levels of irrigation 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 and three nitrogen levels i.e. N1-40 kg ha-1, N2-50 kg ha-1, N3-60 kg ha-1 and N4-70 kg ha-1 as sub-sub plot replicated thrice were undertaken using drip fertigation. All the treatment combinations were evaluated for different growth, seed yield and seed quality parameters. The application of irrigation scheduled at 1.2 IW/CPE recorded significantly higher values for all the growth parameters (plant height, number of branches per plant, days to 50% flowering and maturity), yield attributes (number of umbellets per umbel, number of seeds per umbel, number of seeds per umbellet, seed yield per plant and test weight), seed yield, biological yield, harvest index, NUE, quality parameters (standard germination, seedling length, seedling dry weight, vigour index-I, vigour index-II, accelerated ageing of seed) and BCR over other irrigation scheduling. These were statistically at par with irrigation scheduled at 1.0 IW/CPE. The maximum WUE was found with lower level of irrigation and the minimum electrical conductivity was observed with irrigation scheduling at 1.0 IW/CPE. Nitrogen levels 70 kg ha-1 recorded significantly maximum growth parameters, yield attributes, seed yield, biological yield, harvest index, WUE, quality parameters and BCR of coriander, which was statistically at par with nitrogen applied at 60 kg ha-1. The maximum NUE was found with lower level of nitrogen and the minimum electrical conductivity was observed with N3. Among different varieties, significantly higher growth parameters, yield attributes (except test weight), standard germination under accelerated ageing test and minimum electrical conductivity were recorded with Hisar Bhumit, while the maximum seed yield, harvest index, NUE, WUE, test weight, quality parameters and BCR were obtained in Hisar Sugandh. Its concluded from the current study that coriander variety i.e. Hisar Sugandh found to be superior with respect to growth, yield and BCR when grown at irrigation scheduling at 1.0 IW/CPE and 60 kg/ha of nitrogen level in western region of Haryana.
