The effect of nutrient solutions with varying nitrogen forms on yield and quality of Coriander (cv. Punjab Sugandh) grown in soilless under polyhouse conditions was evaluated. Crop was sown on three dates viz., October (main season), February and July (off-season), respectively. In polyhouse, N (Nitrogen) was supplied in variable ratios of NO3- to NH4+ viz; 100:0 (T1), 75:25 (T2), 50:50 (T3), 25:75 (T4), 0:100 (T5), respectively, keeping total N content constant. Fresh foliage was harvested 3 times in each season at 30 days interval starting from date of sowing. At each harvesting plant growth, quality parameters including activity of antioxidants enzymes were determined. Irrespective of the seasons, the yield was significantly higher in polyhouse and among the nutrient solutions, the solution of T2 recorded higher yield as well as growth and quality parameters during all the season. It could be concluded that NO3- to NH4+ ratio of 75:25 in the nutrient solution improved both yield and quality and is thus most suitable for coriander crop.
