    Effect of nitrogen levels under different spacing on coriander (Coriandrum sativum L.)
    (CCSHAU, Hisar, 2020) Chaman; Malik, T.P.
    The present study entitled, “Effect of nitrogen levels under different spacing on coriander (Coriandrum sativum L.)” was conducted during the Rabi 2019-20 at research farm, Department of Vegetable Science, Chaudhary Charan Singh Haryana Agricultural University, Hisar. The nitrogen doses and different row to row spacing plays important role in growth, yield and quality of coriander crop. In the present investigation four nitrogen levels (0, 25, 50 and 75 kg ha-1) and three different row to row spacing (20 x 15 cm, 30 x 15 cm and 40 x 15 cm) were taken into consideration. The nitrogen was applied in two split doses i.e. 50 per cent at sowing and remaining dose at 40 days after sowing (DAS). Vegetative growth parameters i.e. days to emergence, plant height, primary branches and secondary branches (45, 60, 90 DAS and at harvest), yield and yield attributes were recorded. The quality parameters i.e. test weight, electrical conductivity, standard germination and vigour indices were also recorded in in-vitro condition after harvesting. It was observed that nitrogen dose at 75 kg ha- 1 and row to row spacing 40 x 15 cm was well suited for vegetative growth except plant height that was best in 20 x 15 cm spacing. The seed yield (2119 kg ha-1) and other yield attributes were found highest at 75 kg N ha-1 with spacing 40 x 15 cm and lowest in control. The quality parameters were recorded highest with 75 kg N ha-1 and spacing 40 x 15 cm and the highest cost of cultivation (Rs. 48445 ha-1) was occurred in coriander sown at higher nitrogen levels under different spacing. Among different treatments, highest gross returns of Rs. 158925 ha-1 and highest net returns of Rs. 110480 ha-1 were obtained at 75 kg N ha-1 with 40 x 15 cm. While comparing the, benefit cost ratios, highest B: C (2.29) was recorded at 50 kg N ha-1 with 30 x 15 cm.
