Evaluating the response of Different Chemical and Organic Fertilizers on Carrot Vegetative and Reproductive Characteristics in Gothgaun, Nepal

Abstract

This research aimed to assess the influence of various chemical and organic fertilizers on the vegetative and reproductive characteristics of the New Kuroda variety of carrots (Dacus Carota). The study included the recommended NPK dose (80:60:60 kg/ha), individual components of N (80 kg/ha), P (60 kg/ha), K (60 kg/ha), as well as organic sources such as goat manure (15 t/ha), FYM (20 t/ha), and a control group without any fertilizer. Measurements of growth and reproductive traits were taken at 45, 55, 65, 75, and 85 days post-sowing. Results indicated that the recommended NPK dose consistently outperformed other fertilizer sources in enhancing both vegetative and reproductive parameters. The highest yield of 10.94 tons/ha was achieved with NPK fertilizer, while organic sources like goat manure demonstrated the second-highest growth and development traits. The control group exhibited the lowest growth and development parameters. These results show that these fertiliser sources have a considerable favourable influence on the vegetative and reproductive development of the New Kuroda carrot variety. The outcomes indicate how various fertiliser sources may significantly improve the vegetative and reproductive development of the New Kuroda carrot; the recommended dosage of NPK in conjunction with the supply of goat manure fertilizer stands out as very appropriate techniques for producing carrots. This illustrates how applying a balanced dosage of these fertilisers may lead to increased carrot yield.
