The flower market is on the rise in Brazil. Among the most requested species stands out the ornamental sunflower.However, there are few studies related to the use of organic waste in its production.The objective evaluate the development and biomass production of ornamental sunflower Dwarf Garden under use ofcattle manure. The study was conducted from June to August 2014 in the greenhouse environment. The experimental design was completely randomized with five doses of cattle manure (0; 2.5; 5.0; 7.5 and 10.0 %) of the substrate volume, with five replications and five plants per plot. At 70 days after sowing, period in which the flower was at the R9 stage (physiological maturity), the harvest has begun. It was evaluated the root length, number of petals, green and dry phytomass of root, green and driesphytomass of petals, green and dry phytomasschapter with and without petals, days from the sowing to the appearance of the first floral bud and for initial opening and full of the floral bud. The cattle manure stimulates the production of petals, green and dry phytomass production and increases the precocity of the Sunflower Dwarf Garden. The organic fertilization with cattle manure is an efficient alternative for the production of ornamental sunflower.

Bivalve mariculture is a type of molluscan farming done in open seawater on racks, rafts or longlines where naturally occurring phytoplankton serves as a key food item, introduced into the enclosures with the normal circulation of seawater. Increasingly, the reverse trophic interaction is being recognized; dissolved inorganic and organic waste compounds released by metabolically active bivalves can supply phytoplankton with nutrient and energy requirements for their growth. This two-way interaction can be viewed as a type of community symbiosis developed over long evolutionary timescales. The extent to which this affects overall nutrient budgets and thus primary production is related to the system flushing rate and residence time. Here we reviewed the feeding mechanism and nutrient recycling activities of bivalve and also emphasized the role of phytoplankton as a key nutritional live feed in sustainable bivalve mariculture. Bivalves influence nutrient dynamics through direct excretion and indirectly through microbial mediated remineralisation of their organic deposits in the sediments. The quantitative knowledge of bivalve - phytoplankton trophic interactions in coastal waters will inform bivalve mariculture development to effectively serve the needs of both seafood production and ecosystem restoration.

Financial Aspect

The existence of domestic cattle breeders is a community group that has considerable potential to develop renewable energy resources and environmentally friendly. The methane gas (CH4) produced by cattle manure is a strong greenhouse gas, about 25 times stronger than CO2 if organic waste is not taken up and letting it decay in the open, methane causing global warming. This research is to study the feasibility of processing of domestic cattle manure into biogas with financial analysis. The method used is to analyze the financial aspect by calculating NPV, IRR, and B/C Ratio. This research shows that the potential of raw material of biogas at the research location is great. The utilization of biogas from cattle manure on the household scale is financially feasible, as evidenced by its NPV value indicates >0, its IRR exceeds the interest rate, and its B/C Ratio >1, and the majority of breeders also want to process their cattle manure into biogas.

Composting is an alternative for recycling biodegradable organic waste, transforming it into organic fertilizer that can be used as agricultural nutrients, avoiding its disposal in landfills. This study evaluated the composting of household organic waste as a substitution for cattle manure, with a view to its application in the fertilization of cherry tomatoes (Solanum lycopersicum Mill., Var. Cesariforme). Thus, compost piles were set up using 30% organic waste (carbon source) and 70% tree-pruning residues (filling material). Two sources of organic waste were tested: household food waste (FW) and cattle manure (CM), at five proportions (15% FW + 15% CM, 10% FW + 20% CM, 20% FW + 10% CM and the controls 30% CM and 30% FW). After 90 days, the mature compost from each pile was mixed with coconut fibre in a 1:1 ratio and used as substrate filled in 15 L plastic pots, where the cherry tomato plants were grown. The experiment was conducted under greenhouse conditions in a randomized block design, with five treatments and five replicates. Assessments of growth and leaf mineral composition were performed for the cherry tomato plants. The results indicate that cattle manure can be replaced by household food waste as the organic material used in compost piles. Fertilization with organic compost from household food waste positively influenced the growth and nutrient assimilation in the leaf tissue of cherry tomato.

Abstract The objective of this study was to evaluate the effect of organic waste application on some soil physical properties, growth and yield of red rice between conventional and aerobic irrigation systems on permanent raised-beds. The experiment was carried out in May to August 2020, under Split Plot design with two factors namely techniques of rice cultivation (conventional, T1; aerobic irrigation system, T2) as main plots, and organic wastes (L0=without organic waste, L1=rice husk, L2=rice husk ash, L3=rice husk ash and cattle manure) as the subplots. Results indicated that both treatment factors affected some physical properties of the soil, growth, and yield of red rice. Some variables showed significant interaction namely soil bulk density, red-rice height, leaf number and dry straw weight. Changing rice cultivation technique from conventional to aerobic irrigation system significantly reduced soil bulk density, especially under application of rice husk ash together with cattle manure or without cattle manure, resulting in the highest red rice grain yield of 37.78 g/clump whereas under conventional without organic wastes, grain yield was only 21.27 g/clump. On average, changing from conventional technique to aerobic irrigation system could increase red rice grain yield by 40.13%.

Purpose – The purpose of this paper is to analyze the different types of domestic waste disposal in rural China and the major factors that affect rural household waste disposal behavior. Design/methodology/approach – Stratified and randomly sampled household data are used to describe the disposal of domestic waste in rural China, including domestic garbage and organic waste (human excreta, livestock waste, and kitchen waste); econometric models are estimated to quantify the major determinants of household domestic garbage and human excreta disposal. Findings – While about 30 percent of the domestic garbage in 2008 was discharged to appropriately designated places, more than 40 percent of the garbage was discharged casually. Organic waste at the time of data gathering was still largely used in agricultural production, although a falling trend has been evidenced in recent years. Based on econometric analysis, it becomes clear that income growth, rising population density, and transportation improvements have significantly improved domestic garbage disposal, but negatively affected the recycling of human excreta. The provision of an adequate garbage collection service has the most positive effects on garbage management. Originality/value – The analyses are based on primary survey data. The results will have significant policy implications on the management of rural domestic waste to maintain better rural environment.
