Residual effects of compacted digested effluent on growth of dwarf napier grass in warm regions of Japan
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2016, Vol 4, Issue 0
Abstract
In regional intensive livestock farming, animal waste has a significant dispersal problem. One of the solutions is to process animal wastes to digested effluent of manure (DEM) by the operation of biogas plants. The objectives of the present study were to determine the residual effects of DEM in field application at three levels in the previous two years and the effect of compacted DEM amended with solid manure in a pot trial on production in a dwarf variety of late-heading type Napier grass (Pennisetum purpureum Schumach). Plant growth attributes (plant height, tiller number, mean tiller weight and plant dry weight) in the year examined tended to increase with DEM application rate the previous two years, while the difference between the previous years treatments was less than 25%, the aftereffect of manure application on normal Napier grass was more than 4 times higher. Pot-cultured growth attributes were highest for liquid DEM and chemical fertilizer, followed by a mixture of DEM with manure under the same total nitrogen supply, and decreased significantly with a decrease in the DEM-amended mixture application. Thus, it is concluded that DEM would have a limited residual effect as in the chemical fertilizer plot and a smaller effect than manure application, and a mixture of DEM amended with solid manure should facilitate supplying DEM to forage crops by compaction.
