Organic agriculture in Uganda is developing at a fast pace and despite this trend Uganda is still unable to produce enough fresh and dry organic fruits mainly pineapple to meet the exporters demand. This current research investigated the strategies of farmers at production level by assessing the pros and cons of fruit growing, organic agriculture and fruit drying in order to understand the underlying causal factor for the low production of organic dry fruits in a major fruit producing district of Uganda.The study was carried out in two separate and distinctive areas; one which only produces and export fresh organic pineapple and the other which exports dried fruits (mainly pineapple and papaya). About 10% of the farmers in the two study areas were surveyed...

Casca de café na alimentação de ovinos deslanados. Repositório Alice
TOWNSEND, C. R.; MAGALHAES, J. A.; COSTA, N. de L.; PEREIRA, R. G. de A..
A utilização de alimentos alternativos na dieta animal tem como principais objetivos reduzir os custos e incrementar a produtividade da atividade pecuária, desta forma os mais diversos tipos de resíduos ou subprodutos agroindustriais quando empregados de forma racional podem contribuir para tanto, como é o caso da casca de café. Este trabalho teve por objetivo avaliar o efeito da inclusão da casca de café em substituição ao capim-elefante sobre o desempenho de ovinos deslanados em crescimento

Degradation of caffeine by microorganisms and potential use of decaffeinated coffee husk and pulp in animal feeding Scientia Agricola
Mazzafera,Paulo.
Coffee husk and coffee pulp are coffee processing by-products. Coffee husk is obtained when harvested coffee is processed by the dry method, and coffee pulp is produced by the wet method. In Brazil, coffee is usually processed by the dry method, therefore an expressive amount of husk is obtained every year. Some of the husk is used as organic fertilizer but, other applications are very limited, mainly because it is a bulky product. The presence of tannins and caffeine diminish acceptability and palatability of husk by animals. This review discuss degradation of caffeine by microorganisms, with special attention to bacterial, biological decaffeination of coffee husk and pulp and its subsequent use on animal feeding. The known biochemical routes of caffeine...

Enhanced extraction of phenolic compounds from coffee industry’s residues through solid state fermentation by Penicillium purpurogenum Ciênc. Tecnol. Aliment.
PALOMINO García,Lady Rossana; BIASETTO,Carolina Rabal; ARAUJO,Angela Regina; BIANCHI,Vanildo Luiz Del.
Abstract The use of agroindustrial residues is an economical solution to industrial biotechnology. Coffee husk and pulp are abounding residues from coffee industry which can be used as substrates in solid state fermentation process, thus allowing a liberation and increase in the phenolic compound content with high added value. By employing statistical design, initial moisture content, pH value in the medium, and the incubation temperature were evaluated, in order to increase the polyphenol content in a process of solid state fermentation by Penicillium purpurogenum. The main phenolic compounds identified through HPLC in fermented coffee residue were chlorogenic acid, caffeic acid, and rutin. Data obtained through HPLC with the radical absorbance capacity...

Is Composting a Route to Solubilize Low-Grade Phosphate Rocks and Improve MAP-Based Composts? Rev. Bras. Ciênc. Solo
Maluf,Henrique José Guimarães Moreira; Silva,Carlos Alberto; Morais,Everton Geraldo de; Paula,Leonardo Henrique Duarte de.
ABSTRACT: In alkalinized and Ca-rich composts, solubilization of apatite from phosphate rocks (PRs) is not guaranteed; however, chelating agents and humified substances produced during composting may alter the soluble contents and P forms of monoammonium phosphate (MAP)-based composts. These effects may depend on the proportions of organic wastes and P source used in the compost piles. The aim of this study was to evaluate the effect of composting chicken manure, coffee husk, and Araxá PR, Bayóvar PR, or MAP in different proportions on the organic matter decomposition, total N, Ca contents, and soluble P fractions in the composts. The treatments consisted of a 3 × 4 × 2 factorial, through the combination of three P sources [Araxá PR, Bayóvar PR, and MAP],...

Production of Flammulina velutipes on coffee husk and coffee spent-ground BABT
Leifa,Fan; Pandey,Ashok; Soccol,Carlos R..
Solid state cultivation (SSC) was carried out to evaluate the feasibility of using coffee husk and spent-ground as substrates for the production of edible mushroom Flammulina under different conditions of moisture and spawn rate. The strain of F. velutipes LPB 01 was adapted for a coffee husk extract medium. Best results were obtained with 25% spawn rate, though there was not much difference when lower spawn rates (10-20%) were used. Ideal moisture content for mycelial growth was 60% and 55% for coffee husk and spent-ground, respectively. With coffee husk as substrate, first fructification occurred after 25 days of inoculation and the biological efficiency reached about 56% with two flushes after 40 days. With spent-ground as substrate, first...

Synthesis of enriched biochar as a vehicle for phosphorus in tropical soils Acta Amazonica
MATOSO,Stella Cristiani Gonçalves; WADT,Paulo Guilherme Salvador; SOUZA JÚNIOR,Valdomiro Severino de; PÉREZ,Xosé Lois Otero.
ABSTRACT Phosphorus (P) is one of the nutrients that most limits agricultural productivity, especially in tropical soils. Enriched biochar has been proposed to increase the bioavailability of P and other nutrients in the soil. Thus, the objective of this study was to evaluate the availability of P in phosphate biochar (composed of biomass and soil) as a function of the triple superphosphate mixture before and after the pyrolysis process. We produced eight types of enriched biochar via pyrolysis by combining sandy or clayey soil with rice or coffee husk, and by adding triple superphosphate before or after pyrolysis. The heating of the phosphate fertilizer during the pyrolysis process resulted in a higher crystallinity of the phosphates, lower content of...

Variation in the properties of biochars produced by mixing agricultural residues and mineral soils for agricultural application. Repositório Alice
MATOSO, S. C. G.; WADT, P. G. S.; SOUZA JÚNIOR, V. S. de S.; PÉREZ, X. L. O..
The research and application of biochars enriched with minerals have increased in recent years; however, the mineral fraction used consists of specific minerals, such as clay minerals and synthesized compounds. In this work, the effects of adding two specific soil types (sandy and clayey) to rice and coffee husks in order to generate biochars via pyrolysis was investigated. Chemical, physical?chemical, thermal, spectroscopic and crystallographic analyses were conducted on the produced biochars. The study confirmed that the presence of mineral soils during the pyrolysis process increases the yield, C retention ratio, and specific surface area. It also decreases the pH, cation exchange capacity (CEC), nutrient content, and carbon-to-nitrogen ratio of...
