Nitrogen is considered one of the critical mineral nutrients for the healthy growth of plants. Hence, its judicious use is necessary for the sustainability of crop production. A study was carried out to investigate the growth and yield of cucumber (Cucumis sativus cv. Bhaktapur Local L.) in response to different Urea applications. The trial was conducted at Baglung district in Randomized Complete Block Design (RCBD) with four replications. The treatments were five levels of Urea: 0, 140, 180, 220, and 260 kg/ha. The results exhibited that all the growth and yield attributes were significantly affected by Urea applications. The crop treated with a higher Urea level of 260kg/ha significantly showed higher values for most of the evaluated traits. The crop fertilized with a Urea level of 260 kg/ha produced 312.19 cm vine length, 32.90 cm fruit length, and 700.16 g fruit weight. However, crops fertilized with a Urea level of 220 kg/ha produced a more significant number of fruits of plants i.e., 6.04 subsequently resulting in higher yield i.e., 17.24 mt/ha as compared to other treatments. On the contrary control plots which were not fertilized showed an adverse effect on plant growth and yield and produced 164.54 cm vine length, 49.778 leaves vine, 38.380 days to flower initiation, 10.380 cm fruit length, 5.497 fruit vine, 466.6 g fruit weight and 4.914 ton/ha fruit yield. Based on the findings of the current study, it is concluded that a higher Urea level of 220 kg/ha showed significantly higher yield. Hence, cucumber may be fertilized with a Urea Level of 220 kg/ha for desired growth and yield.
