Response of Sweet Potato (Ipomoea Batatas L.) Variety to Nitrogen and Farmyard Manure Fertilizer Application in Mulo District, Ethiopia
Year: 2025
Type: article
Abstract: A field experiment was carried out during the 2020–2021 growing season to examine how the sweet potato responded to various doses of organic and inorganic fertilizer. The treatment included three levels of farmyard waste and four levels of nitrogen fertilizers (0, 40, 70, and 100 kg N ha-1) (0, 5and 10 FYM t ha-1). The experiment was performed three times and set up using a Randomized Complete Block Design in a factorial layout. Software called SAS (version 9.3) was used to examine the data. The findings showed that the majority of the growth, yield, and yield components were significantly (P 0.01) impacted by the application of N and farmyard manure fertilizers. The highest and lowest vine lengths measured were 160.23 and 112.17 cm, respectively. Other measurements included shoot fresh weight (1009.6 and 109.8 g hill-1), shoot dry weight (141.35 and 61.6 g hill-1), days of bud sprouting (13.27 and 6.34), days of physiological maturity (147.8 and 119), number of branches per plant (7.30 and 4.28), harvest index (0.36 and 0.28%), biomass yield (1009.2 and 579.7), tuberous storage tuber diameter (22.5 and 15.6 cm), total tuber yield (22.45 and 7.05 tha-1), marketable tuber yield (21.85 and 7.65 tha-1), unmarketable tuber yield (3.25 and 0.31 t/ha), marketable storage tuber number (3.2 and 0.83), and un marketable tuber number (0.38 and 0.02) were obtained from 10t ha-1farmyard manure plus 100 kgha-1 N fertilizer. However, the above-mentioned factors were countered by the number of branches per plant, the quantity of unmarketable tubers, and the yield of unmarketable tubers. In conclusion, the findings showed that the application of inorganic nitrogen fertilizer along with farmyard manure might improve the growth, production, and yield components of sweet potatoes. To get more trustworthy data, though, additional research must be done in various environments and at various times of the year while taking fertilizer rates for nitrogen and FYM into account.
