Crop model simulates growth and yield of crop in field scale and can be used to provide useful field information for farmers, such as irrigation application dates and amount, fertilizer application dates and amount, the choose of crop variety. Researchers have used crop models for many years, but they have had limited success in packaging these complex models in a framework that make them easy ...

Introduction: This study is aimed at analyzing farmers’ perception and adaptation to climate change in the Dabus watershed. It is based on analysis of data collected from 734 randomly selected farm householdheads substantiated with Focus Group Discussions and field observations. Methods: The study employed descriptive methods to assess farmers’ perception of climate change, localindicators of c...

Climate change is expected to adversely affect the crop yields and food security for many smallholder farmers in tropics unless adaptive measures are implemented. Agroforestry ecosystem services, such as micro-climate buffering, have received growing attention from academic policy communities alleviating negative impacts of climate on smallholders. These benefits imply that agroforestry could o...

This study was designed to measure technical efficiency and identify its determinants in crop production in Lafia Local government Area of Nasarawa State of Nigeria using a stochastic frontier production model. Double stage random sampling technique was used to select 100 crop farmers from which input-output data were collected based on 2005 cropping season. The results revealed that sixty five...

Row-crop agriculture is one of the most extensive and closely coupled natural– human systems and has extraordinary implications for human welfare and environmental well-being. The continued intensification of row-crop agriculture provides food for billions and, for at least the past 50 years, has slowed (but not stopped) the expansion of cropping onto lands valued for conservation and other env...

Findings 1 Smallholder upland farmers plant native timber trees depending on several interlinked factors:-If land is available and they can achieve security of land tenure.-If access to natural forest is restricted or forbidden.-If they have enough land and it is not divided into disparate portions. 2 A number of native timber species in early stages of domestication are suitable for intercropp...

IInstitutional analysis can be used to understand the value placed on crop diversity by farmers as a social process, and to uncover the market-related constraints and incentives that influence farmer management of genetic resources. This is particularly important for capturing the dynamics of crop populations and the collective impact of individual decisions regarding crop diversity. In the app...

Farmers’ decisions about how much crop insurance to buy are not generally consistent with either expected profit or utility maximization. They do not pick coverage levels that maximize expected subsidy nor do they demand full insurance coverage. In addition, the absolute size ...

Similarly, at the beginning of NAFGEN, the Canadian hemp industry was in its 10 year of commercial growth and had developed into a $20 million dollar industry. Most of the commercial growth to date had been driven by the vigorous seed sector, fuelled by demand in the health food and body care products sector. NAFGEN’s vision included laying the ground work for establishing value-added hemp fibr...

Scorching summer heat in South America is cutting harvest forecasts in one of the world’s critical farm belts, helping to propel crop prices to new two-year highs and fuelling concerns about global supplies. However, a new study has revealed how resourceful farmers have been in the past to facing new conditions. Dry weather, considered to be influenced by the La Niña weather pattern, is already...
