Purpose The research was performed to assess the effect of vermicompost and tuber size on the storage behavior of potato during the ambient condition. Method The research was consisted of two factors, i.e., factor A: vermicompost level (Vm-4): Vm1: 0 t ha−1 (control), Vm2: 3 t ha−1, Vm3: 6 t ha−1, and Vm4: 9 t […]
Purpose Recovery of nutrients from water using duckweed and their reuse has significance in closing the loop on nutrient transfer from anthropogenic sources. This study investigated the effect of rate of application and pre-incubation period of duckweed on biomass and nutrient uptake of Swiss chard (Fordhook giant). Method Two glasshouse experiments were laid out in […]
Purpose Despite durum wheat accounts for only 5% of the global wheat production, it represents an economically important species, as a basic food and primary source of daily caloric intake in the Mediterranean basin area. By-products of agricultural processing, such as pomace, can be used to increase soil fertility, as they are indeed a source […]
Purpose Aquaponics combine aquaculture with crop production in a mutual system. In this experiment, the growth of Amaranthus in aquaponics with tilapia fish was investigated. Method 500-liter water tanks containing tilapia fish at four initial stocking densities of 100, 150, 200, and 250 fish/m3 were used in triplicates, with a view to evaluate vegetable yields as influenced by […]
Purpose Amylase being one of the most important industrial enzymes requires large-scale production. When producing an enzyme, high productivity, high purity and low production costs need to be considered. This study focuses on comparing various agro-industrial waste substrates, for production of alpha-amylase using Bacillus amyloliquefaciens. Moreover, it studies the stability and activity of amylase–gold nanoparticles […]
Purpose Rice-mill wastes are generated in large amounts in Ishiagu, Ebonyi State, Nigeria. These wastes can potentially be utilized for rice production and in improving soil attributes. This study evaluated the effects of rice-mill wastes on soil chemical properties and rice yield in sawah rice management. Method A sawah rice field in an inland valley […]
Purpose Source segregation of food waste is one of the major challenges that inhibit food waste recycling around the world. Therefore, the purpose of this study was to investigate the role of the local authority to implement regulations and encourage an increase in the source separation of food waste within both commercial premises and households, […]
Purpose This study aimed to design a biogas digester that works thermophilically and mesophilically and tested its performance to produce biogas and digestate. Method This study used some experimental methods, which consists of: (1) design and construction process of the digester which can facilitate the thermophilic process as a pretreatment of the feedstock and the […]
Purpose Utilization of food waste as composting materials offers a sustainable solution to manage waste and reduce reliance on fertilizers. Method This study is focused on the efficiency of food waste compost and the effect of the addition of magnetite (Fe3O4) nanoparticles on the growth and heavy metals uptake by roselle (Hibiscus sabdarifa) for the […]
Purpose This study aims to evaluate the potential negative effects of rice husk as a source of fertilizer on plant growth. Method Growth tests were conducted on komatsuna (Brassica rapa var. perviridis) using three types of experiment. A pot experiment was conducted to compare different fertilizers on an individual basis. A second pot experiment was conducted […]
