Purpose This field study evaluated the interactive effects of biochar (BC) and sewage sludge (SS) on P bioavailability and spinach yields for two seasons. Method Treatments were combinations of biochar (0, 2.5 and 5 Mg ha-1) and sewage sludge (0, 6 and 12 Mg ha-1), or mineral fertilizer (200, 28, and 18.9 kg ha-1), amended […]
Purpose: Millicompost is an organic substrate generated by the activity of millipedes (diplopods) with high potential for seedling production. This work aimed to evaluate the performance of green curly lettuce (Lactuca sativa L.) using seedlings produced with millicompost, at different levels of nitrogen (N) fertilization at seedling transplant, in an organic production system. Method: […]
Purpose: The current study aimed to figure out the types and dosages of biocomposts supplied with cellulose-degrading Trichoderma strains for ameliorating soil properties, and the growth and yield of pineapple. Method: The experiment with two factors followed a completely randomized block design, including 20 treatments (4 replications). The first factor (A) was the types of […]
Purpose The shell of cocoa beans is one of the cocoa industry byproducts that currently still become waste. Through this research, utilization of cocoa bean shell for producing alkalized fiber powder was observed. The aim of the study is producing fiber powder from the shell of cocoa beans. Methods The shell of cocoa beans was […]
Purpose: This work was aimed to exploit the technique of design of experiments to evaluate the olive mill waste cake residue obtained after oil extraction while searching for an adequate composition of the initial substrate mixtures (RPM, DMOV, FV and EB for humidification), in addition to validate it experimentally. Method: To this end, a mixture […]
Purpose This research aims to characterize the physical and chemical properties of biochar derived from biodegradable domestic solid waste and sugarcane bagasse, in order to evaluate their possible uses in agronomic and environmental applications. Method Biodegradable domestic solid waste and sugarcane bagasse-based biochar were pyrolyzed at two pyrolysis temperatures (500 and 700 °C). Biochar properties included the […]
Purpose: A study was conducted to transform bovine blood, a slaughterhouse by-product, into an organic source of nitrogen, which is otherwise disposed of through sewer systems only to pollute the nearby water bodies. Method: The annual blood production in the Khulna City Corporation (KCC) slaughterhouses was estimated, blood samples were collected, and blood meals were […]
Purpose The aim of this work was to study the effect of adding sugar beet molasses on the biochemical properties, microbial flora, fermentation quality, and aerobic stability of prickly pear cactus (Opuntia ficus-indica) waste silage. Method Molasses (0%, 2%, 4%, 6%, 8% and 10%, w/w) was mixed with the cactus fruit scraps, straw and wheat […]
Purpose: Cocopeat resources in Iran are limited and unsuitable, and they must be imported from abroad at a high cost. It is therefore essential to evaluate suitable growth media to replace cocopeat. Method: During this experiment, we conducted a completely randomized experimental design with seven types of growing media in a greenhouse with two layers […]
Purpose: This study aimed to investigate the effects of vermicompost leachate on the growth and water use of tomatoes in an unequal distribution of salinity in a hydroponic system. Method: Roots of tomato seedlings were separated into approximately two equal parts, each half was grown in a media culture part containing a 3-liter perlite and […]
