| Abstrak Mustard greens are vegetables that grow faster and are resistant to low temperatures. This study aims to find the right dose for the growth of mustard greens. This research was conducted in August 2019, at the Green house of the Faculty of Agriculture, Tadulako University, the soil sample came from Sp 1 Sidera Trans Regency. Sigi and Soil Analysis was carried out at the Soil Science Laboratory, Faculty of Agriculture, Tadulako University, Palu. The treatment consisted of 5 levels. This study used a completely randomized design (CRD) in the form of cow manure, namely, M0 = No Fertilizer. M1 = 10 g of cow manure / 5 kg of soil. M2 = 20 g of cow manure / 5 kg of soil. M3 = 30 g of cow manure / 5 kg of soil. M4 = cow manure 40 g / 5 kg of soil. The results showed that the application of cow manure was able to improve several chemical properties of the soil in terms of pH value, and soil nutrient levels including K-totol soil, the highest soil pH was obtained at a dose of 30 g is 6.56 while the lowest soil pH is at a dose of 10 g, which is 6.51. The highest organic C is found at a dose of 40 g. ie 2.60 while the lowest C-Organic was found at a dose of 10 g. ie 2.30 . For the highest availability of K-Total that is 40.45 achieved at a dose of 40 g and the lowest K-total is found at a dose of 10 g which is 20.76. The application of cow manure has a very significant effect on C-Organic and K-total in the soil Keyword: Cow Manure, K-Total Soil, Mustard Plant Growth. |
