Abstract

The growth of fodder plants is strongly influenced by environmental factors, namely soil as a provider of nutrients, soil temperature, soil moisture, sunlight energy for photosynthesis and air that provides CO₂and O₂for the needs of the plant itself. Related to this, a study was conducted to evaluate the dosage of Liquid Organic Fertilizer (LOF) made from cow feces with different doses and frequency of watering on dwarf elephant grass or kate’s elephant grass (Pennisetum purpureum cv Mott) on soil temperature, soil moisture, soil organic and N-total vertisol in Timor Leste. The experiment used a Completely Randomized Design (CRD) with a factorial pattern with 2 factors: Factor A (LOF dose): P2 (1 liter LOF:2 liters of water), P4 (1 liter LOF:2 liters of water), P6 (1 liter LOF:6 liters of water), (1 liter LOF:8liters of water), and factor B is the frequency of LOF application consisting of W2 (LOF given every 2 days),W4 (LOF given every 4 days),W6 (LOF given every 6 days). The experiment used four replications so that there were 48 experimental units. The results showed that there was an interaction between dose of LOF and frequency of application of LOF on the variable soil moisture vertisol.
