- Optimum quantity of fertilizers and irrigation water to minimize the cost and increase the production is need of the day. Consequently, an experiment was conducted at CCS Haryana Agricultural University, Hisar during the winter season of 2014–15 and 2015–16 to study the effect of irrigation schedules and fertilizer levels on coriander. Irrigation at 25, 50, 75, and 100 days after sowing (DAS) gave higher growth and yield attributing characters, seed yield (16.48 q/ha), biological yield (50.79 q/ha), net return (Rs. 138,950.6), and benefit to cost ratio (2.36), which resulted in 40.9% and 15.3% increase in seed and biological yield over two irrigations, respectively. The application of fertilizers, i.e., N₆₀ and P₅₀ kg/ha, registered higher growth, seed yield attributes, consumptive use of water, whereas, net return and benefit to cost ratio was recorded maximum under fertilizers, i.e., N₇₅ and P₆₂.₅ kg/ha. The interaction effect of irrigation and fertilizer on seeds per umbellet and seed yield was also found to be significantly positive. Hence, in Northern Plains of India four irrigations at 25, 50, 75, and 100 DAS in association with nitrogen 75 kg/ha and phosphorus 62.5 kg/ha is more profitable in coriander crop.
