Effects of Integrated Application of Vermicompost and Chemical Fertilizer Rates on Tube Yield and Economic Benefit of Potato (Solanum tuberosum L.) in Chilga District, North Western Ethiopia
Description
A field experiment was conducted to test the significant effects of integrated application of vermicompost and different proportionds recomended chemical fertilizer rates on economic benefit, tuber yield and yield attributes. data were collected from plots on which assigned for four vermicompost rates (0, 2.5, 5 and 7.5 t ha-1) and four chemical fertilizer rates (0, 25, 50 and 75% recommended does of chemical fertilizer rate which were laid out in a Randomized Complete Block Design (RCBD) with three replications. data were analyzed using R-software version 4.4.2. Means were separated using the least significant difference test at a 5% probability level. The results showed that all the tested parameters were significantly influenced by vermicompost and chemical fertilizer rates. The combined application of 7.5 t ha-1 VC and 75% RDCF resulted in the maximum values of plant height (73.33 cm), marketable tuber yield (30.22 tha-1), total tuber yield (34.22 tha-1), tuber dry matter content (25.73%) and net benefit (Birr 557,800 ha-1). Hence, combined application of 7.5 t ha-1 VC and 75% RDCF isthe the best treatment for the production of potato in the study area and similar environment.
