Agricultural production system is an outcome of a complex interaction of seed, soil, water and agro-chemicals (including fertilizers). Therefore, judicious management of all the inputs is essential for the sustainability of such a complex system. The focus on enhancing the productivity during the Green Revolution coupled with total disregard of proper management of inputs and without considerin...

Chloride is a relatively unreactive plant nutrient that has long been used as a biogeochemical tracer but also can be a pollutant causing aquatic biology impacts when concentrations are high, typically from rock salt applications used for deicing roads. Chloride inputs to watersheds are most often from atmospheric deposition, road salt, or agricultural fertilizer, although studies on agricultur...

This paper examines the viability and effectiveness of a pilot farming initiative in reversing impacts of HIV/AIDS on the most affected households in Homa Bay, Kenya. The paper argues that once patients are stable, they can effectively be engaged in farming with minimal financial and technical support, resulting in enhanced food security of the affected households. More importantly, it helps to...

(exogenous, tradable) income as a result of structural changes such as technological progress, improvement in export prices, etc.. Thus, a multiplier of 2.0 suggests an addition of $1.00 on extra income for each $1.00 of new agricultural income , through a re-spending on non-tradable consumer items and intermediate inputs. PAST TRENDS AND FUTURE PROSPECTS FOR AGRICULTURAL DEVELOPMENT IN SUB-SAH...

Conventional wisdom holds that Sub-Saharan African farmers use few modern inputs despite the fact that most poverty-reducing agricultural growth in the region is expected to come largely from expanded use of inputs that embody improved technologies, particularly improved seed, fertilizers and other agro-chemicals, machinery, and irrigation. Yet following several years of high food prices, conce...

There are, however, other concerns that determine choices towards organic management. Conversion to organic agricultural systems are triggered by different objectives, such as: securing a place on international markets, export promotion, economic self-reliance, finding alternatives to decreased access to agricultural inputs, natural resource conservation, food self-sufficiency, and rural and wi...

We identify the agricultural inputs that drove the growth in global Background and regional crop yields from 1975 to the mid-2000s. : We compare Methods and contrast the inputs that drove yield change as identified by econometrically estimated yield functions and decision trees that use yield change as the class attribute. : We find that improvements in agricultural science and Results managem...

This paper estimates the role of agronomic inputs in cereal yield improvements and the consequences for countries' processes of structural change. The results suggest a clear role for fertilizer, modern seeds and water in boosting yields. We then test for respective empirical links between agricultural yields and economic growth, labor share in agriculture and non-agricultural value added per w...

Two different patterns in input–output relations can be distinguished in agricultural production. For the first, yields are obtained at zero rates of certain external inputs, such as in wheat growing, or dairying based on grazing. For a second type of input–output relation, inputs are required before any yield can be obtained, such as in irrigation schemes in desert areas, or industrial product...

This study was undertaken to investigate the impact of microfinance on agricultural productivity by smallholder farmers in Makurdi Metropolis of Benue State, Nigeria. Data were randomly collected from 120 farmers consisting of 60 credit beneficiaries (CB) and 60 non-credit beneficiaries (NCB) by which were analyzed through descriptive statistics and multiple regression analysis. The results of ...
