ABSTRACT
The experiment was conducted at the Agricultural Research Field of International University of Business Agriculture and Technology, Dhaka during the period from August to October 2020 to investigate the response of different doses of nitrogen fertilizer on the growth and yield of Kangkong (Ipomoea reptans poir). The experiment consisted of four nitrogen fertilizer levels viz. T0: no fertilizer, T1: 60 kg nitrogen fertilizer, T2: 80 kg nitrogen fertilizer, and T3: 100 kg nitrogen fertilizer per hectare. The result revealed that plant height, number of leaves per plant, number of branches per plant, fresh weight per plant, dry weight per plant, root length per plant, fresh weight of root per plant, dry weight of root per plant, yield per plot and yield per hectare grown under different doses of nitrogen fertilizer viz. control (T0), 60 kg N per hectare (T1), 80 kg N per hectare (T2), showed significant reduction than those grown in 100 kg N per hectare (T3). The experiment was conducted following Randomized Complete Block Design (RCBD) with four replications. The application of different doses of nitrogen significantly influences the growth and yield of Kangkong. The maximum plant height, number of leaves, number of branches, fresh weight per plant, root length was obtained from T3 treatment while the minimum was found from the control treatment (T0) at 60 days after sowing. The highest yield (17.87 t/ha) was performed from the treatment T3 and the lowest yield (11.83t/ha) was obtained from the control treatment where no nitrogen was used.
