A field experiment on “Response of Sweet corn hybrid to transplanting dates and nitrogen levels under temperate conditions” was conducted at research farm of Faculty of Agriculture (SKUAST-K) during 2016. The soil of the experimental field was silty clay loam in texture, low in soil available N and P and medium in available K and neutral in reaction. The treatments comprised of two transplanting dates viz., 1st of May and 1st of June and five levels of N viz., 0, 30, 60, 90 and 120 kg/ha. Although latter date of sowing resulted in better quality of seedlings but 1st May transplanting was superior in all growth and yield attributes. 1st May transplanting resulted 35.4% and 19.8% higher cob yield and green fodder yield over 1st June transplanting, respectively. Nitrogen application resulted in a significant increase in growth and yield parameters. The green cob yield increased by 34%, 44%, 52%, and 54% respectively at 30, 60, 90 and 120 kg/ha N over control. The corresponding figures for the green fodder yield were 39%, 70%, 91% and 108%, respectively. Highest net profit and benefit cost ratio was realised in 1st May transplanting applied with 120 kg N/ha.
