Pengaruh kombinasi pupuk kandang dan pupuk NPK terhadap pertumbuhan tanaman tomat cherry (Solanum lycopersicum var. cerasiforme)

Abstract

The use of inorganic fertilizers without being balanced with organic fertilizers can have a negative impact on soil nutrients absorbed by plants. Therefore, a study was conducted on the effect of a combination of manure and NPK fertilizer on the growth of cherry tomato plants (Solanum lycopersicum var. cerasiforme). This study aims to determine the effect of a combination of manure and NPK fertilizer on plant height and number of leaves on the growth of cherry tomato plants. The research method used was an experiment with a completely randomized design (CRD) consisting of 2 factors which were repeated 3 times. The first factor was giving POC doses with 4 levels, namely K0 = control, K1 = POC 4 ml/L, K2 = POC 8 ml/L, K3 = POC 12 ml/L. the second factor was the administration of NPK doses with 4 levels, namely N0 = control, N1 = NPK 20 g/L, N2 = NPK 25 g/L, N3 = NPK 30 g/L. parameters were observed for 12 weeks after planting. Data were analyzed using the One Way Anova test and the Kruskal-Wallis test with insignificant results, but optimal results were obtained for each parameter. The results showed that the N1K1 combination treatment gave optimal results for tomato plant height (148.33 cm). The N0K2 treatment gave optimal results on the number of leaves of tomato plants (144 leaves).
