Production and King Grass Nutritional Quality Number of Sources of Nitrogen Fertilizer

Abstract

The aim of this study was to obtain the best nitrogen source and level of information on plant growth, production, and nutritional quality of king grass forage (Pennisetum Purpureophoides). The source of nitrogen comes from natural fertilizers (chicken and cow manure) and artificial fertilizers (urea and NPK). The method was completely randomized with the BNJ further test with a confidence interval of <0.05. The research plan consisted of 2 factors: the type of fertilizer (organic; cow and chicken manure); inorganic fertilizers (NPK and urea + nitrogen); and the second factor, the dosage (50, 75, and 100 kg/ha/defoliation). Observation parameters were plant height, stem diameter, number of plants per clump, fresh forage production, dry matter production, dry matter content, crude protein content, crude fibre content, and crude fat content. The results of the study using modifications in fertilizing king grass to increase carbon sources and nutrients obtained significant results. The average plant height was obtained between 60-263 cm. The largest size was at defoliation 1, and the lowest was at defoliation 4. Plant diameter increased between 9.97–12.43 mm, with tiller production in plants increasing to 18.5–25.8 planting. The increase was also followed by the number of fresh leaves and a decrease in the number of dry leaves. Protein content increased with the higher dose given at 11.78% BK, with a crude fiber value of 34.41% BK. King Grass contains a good source of carbon nutrients and can affect the increase in plant growth with a higher plant height and a higher number of leaves. Doi: 10.28991/HIJ-2022-03-03-02 Full Text: PDF
