Effectiveness the source of nitrogen from NO3 and NH4 for Panicum maximum Jacq. growth in saline soil
2019
Abstract The purpose of this study was to determine the source of nitrogen used by Panicum maximum Jacq. plants in salt soil. Experimenting pots in a greenhouse with a medium of saline soil. The 2 × 3 factorial design is used in repeated trials. The first factor is calcium sulfate (0 and 2 t ha−1), the second factor is N fertilizer includes (a) without nitrogen = N0, (b) 60 kg N of potassium nitrate (KNO3) and (c) 60 kg N of ammonium sulfate (NH4SO4). The parameters observed were nitrogen uptake, constant growth rate (CGR), biomass yield, crude protein content, NDF, and ADF. The interaction of calcium sulfate and nitrate fertilizer increases CGR, biomass yield, N, CP and NDF uptake. Interac…
Lignin and Cellulose Content of Fermented Rice Straw with Aspergillus niger (van Tieghem) and Trichoderma mutan AA1
2021
The rice straw has potential to be used as an alternative ruminant feed. However, it has limiting factors i.e low crude protein, high crude fiber, lignin, cellulose, and silica content. To overcome the limiting factors, immersion in a solution of alkaline (lime) or fermentation by using inoculum microbial cellulolytic and lignocellulolytic (Trichoderma mutan AA1 and Aspergillus niger.). The research method was experimental, with four treatments and repeated five times. Completely randomized design was used and if there are differences among treatments a further test with DMRT was carried out (level 1 % and 5 %). These treatments were T0: The rice straw without t fermentation; T1: Fermented …
