Abstrak

The aim of the study was to examine the response of elephant grass (Pennisetum purpureum) to various types and dosages of inorganic and organic fertilizers and to obtain optimal doses of various types of fertilizers. The study used a completely randomized design with a factorial pattern of two factors. The first factor was the type of fertilizer (A = inorganic NPK; OP = factory organic; BO = bioorganic; BS = bio-slurry) and the second factor was the dose of fertilizer (D0 = without fertilizer; D1 = 100 kg N ha-1; D2= 200 kg N ha-1; D3 = 300 kg N ha-1). There were 16 treatment combinations and each treatment was repeated 3 times. The results showed that types of bioorganic fertilizer produced higher plant height and stem diameter than inorganic fertilizer. The types of bioorganic and bio-slurry fertilizers resulted in higher leaf dry weight, stem dry weight and total dry weight of forage compared to inorganic fertilizer. Fertilizer dose of 300 kg N ha-1 showed higher stem dry weight and total dry weight than without fertilizer treatment. It was concluded that the response of elephant grass (Pennisetum purpureum) to the application of bioorganic and bio-slurry fertilizers was better than that of inorganic and factory organic fertilizers. Dose of 300 kg of N ha-1 fertilizer increased the yield of elephant grass (Pennisetum purpureum), and there was no optimal dose of various types of fertilizers.
