Economic Analysis Of Smallholder Organic Vegetable Production System In Kiambu And Kajiado Counties Of Kenya

Abstract In Kenya, there are more than 200,000 farmers who have been trained on organic farming technologies and systems. Currently certified land under organic management in Kenya stands at 104,211 ha while the organic sub sector employs 12,647 farmers who are directly involved in production of different organic products. Although there are many documented reasons that make farmers to adopt organic farming system, economic benefits present one of the major motivations. These benefits however...

Economic and Ecological values of Frass Fertiliser from Black Soldier fly Agro-industrial waste processing

Abstract: The sustainable utilisation of black soldier fly (BSF) for recycling organic waste into high-quality protein feed and organic fertiliser with a low environmental footprint is gaining momentum worldwide. Although BSF farming is becoming a rapidly growing agribusiness, studies on the BSF farming’s economic aspects are limited. This study analysed the economic benefits of farming BSF for animal feeds and composted frass, called frass fertiliser (FF) production using experimental dat...

Effects of organic and inorganic soil amendments on growth performance of plantain (Musa paradisiaca L.)

A field experiment was conducted to investigate the comparative effects of organic and inorganic soil amendments on growth and performance of plantain (Musa paradisiaca). The experiment was established in March 2011 and repeated in February 2012. The treatments consisted of nine soil amendments (NPK sole, Jatropha sole, palm kernel cake (PKC) residue sole, Sunshine organo-mineral sole, NPK + Jatropha husk 50:50, Sunshine organo-mineral + Jatropha husk 50:50, PKC residue + NPK 50:50, PKC resid...

CONTRIBUTION OF FLORA DIVERSITY TO SUSTAINABLE LIVELIHOODS OF ORGANIC AND CONVENTIONAL COCOA FARMERS IN THE ATWIMA MPONUA DISTRICT

ABSTRACT The aim of the study was to determine the difference in flora diversity in two farming systems and how the diversity contributes to sustainable livelihoods of cocoa farmers in an era of changing climate in Atwima Mponua District of Ghana. Sixteen organic and sixteen conventional cocoa farms were selected in Gyereso and Pasoro in the district. In each farm, flora were sampled to include three life forms viz., trees, shrubs and herbs. Households were also interviewed with a structured ...

Organic Carbon And Nutrient Dynamics Under Crop-Livestock Farming System In Haramaya And Kersa Districts, Eastern Ethiopia

EXTENDED ABSTRACT The crop-livestock farming system is a traditional and main agricultural practice in the eastern part of Ethiopia, where crop grains are produced for food security and residues are for animal feed and domestic fuel consumption. As a result, farmers practice crop residues removal management throughout the cropping seasons. However, there is no adequate information on the impacts of crop residues removal management on soil properties and crop yields under such farming system. ...

Sorption And Desorption Of Selected Organic And Inorganic Pollutants In Soils Collected From Different Agro-Ecological Zones Of Nigeria

ABSTRACT Environmental pollution caused by persistent and bioaccumulative toxic chemicals is a global issue in view of its effects on biota. Researches abound on the sources and concentration of soil pollutants but there is paucity of information on their sorption/desorption in Nigerian soils. This is necessary for accurate prediction of toxicity and effective remediation strategy. Therefore, this study was aimed at assessing the sorption/desorption of selected organic and inorganic pollutant...

Impact Of Interventions By One Acre Fund On Maize Yield And Farm Profits In Busia County, Kenya

ABSTRACT Maize is a staple food and its adequacy is a measure of food security in Busia County and across Kenya. Despite myriad efforts to increase its yield, the national level has remained low at 1.6 tons/ha relative to world average of 5.5 tons/ha and Busia County experiences much lower yield of 1.2 tons/ha. This low yield in the county coupled by high population growth rate arising from a fertility rate of 6 percent in the county when national level is 4.6 percent and a large population ...

CURTAILING FERTILIZER SCARCITY AND CLIMATE CHANGE; AN APPRAISAL OF FACTORS AFFECTING ORGANIC MATERIALS USE OPTION IN NIGERIA'S AGRICULTURE

Abstract Global trends nowadays towards long term sustainable crop production is hinged on either supplementing the use of chemical fertilizers with organic materials or a complete use of organic materials. This is more so since substituting chemical fertilizers with organic materials reduces the risks of exposure to ailments that arise on account of synthetic compounds and increases farmers’ gains via reduced soil erosion and carbon emissions and increased bio-diversity. The current study ...

Effects Of Deficit Irrigation On Growth Parameters And Yield Of Organic And Inorganic Fertilized Dry Beans (Phaseolus Vulgaris L).

ABSTRACT Organic manure supply to soil with inorganic or on its own is good soil management practice improving crop quality and overall soil fertility. Increasing water demand on many sectors and evident reduction of water allocated to agriculture is of importance prompting exploration of the more efficient water use techniques to maximise production. Local small holder communal farmers are faced by challenges of lack of access to inorganic fertilizers due to economic constrain and lack of ca...

Effects Of Poor Business Enabling Environments On The Organic Value Chain In Zimbabwe. The Case Of Hwedza Organic Farmers Association

ABSTRACT Agriculture forms the backbone of most African economies and as such it is subject to experimentation in a bid to improve it and gain more from it. The agricultural trajectory has an element of universalism despite its settings and this normally proves consequential to the developing countries as some of the elements that make up its trajectory are not supported by other underlying reasons. It is the element of agricultural universalism that had most African countries adopt the Green...

Effects of Fertilizer, Lime and Organic Manure on the Nodulation and Growth of Soybean (GLYCYNE MAX(L) MERRILL) in South Eastern Nigeria

A BST RA CT Green house experiment was conducted to study the effects of organic manure, lime and inorganic fertilizer on the nodulation and growth of Soybean (Glycine max(L) merrill) on an acid ultisol in southeastern Nigeria. The organic manure was poultry manure, the lime was commercial lime and the inorganic fertilizer was NPK(15 : 15: 15). There were 7 treatments and a control. The treatments were 100kg/ha inorganic fertilizer (NPK 15: 15: 15)(F1 );200kglhainorganicfertilizcr(NPK 1...

Effect Of Organic And Inorganic Fertilizers On Growth, Yield And Quality Of Amaranths In Kiambu County, Kenya

ABSTRACT An experiment was carried out for two seasons in Kiambu County to investigate the influence of organic and inorganic fertilizer on growth, anti-nutrients characteristics in amaranth species and the changes in the soil rhizosphere. This is because continuous usage of inorganic fertilizer affects soil structure. Hence, organic manures can serve as alternative to mineral fertilizers. Application of pesticides and inorganic fertilizers had adverse effects on nutrient leaching, pesticide...

Effect Of Compost And Inorganic Nitrogen Fertilizer On Nutrient Uptake, Growth And Grain Yield Of Nerica Rice

Increasing inorganic fertilizer costs for food production and energy requirement for inorganic fertilizer production suggests the need to supplement the nutrient requirement of crops through organic amendments such as crop residues, manures and composts. Combined use of organic and inorganic fertilizers can improve rice productivity and sustain soil health and fertility. A pot experiment was conducted to compare the effects of N source as compost (organic), inorganic fertilizer (inorganic) or...

Study Of The Effect Of Successive Cropping's Of Organic Phosphorus Content Of A Selected Ghanaian Soil Using Four Different Crops

Abstract Phosphorus does occur both in organic and inorganic forms, and a*, relatively large amount is present in organic foraf* Relatively little work has been done on organic phosphorus in Ghanaian soils. Some research workers notably Schollemberger (1920), Dean (1938) and a number of others have found that soils high in organic matte* are also high: in organic phosphorus. Bye and Bertheux (1957) working on Ghanaian soils observed considerably more organic phosphorus in forest soils than in...
