Human-wildlife conflict often arises from crop-raiding, and insights regarding which aspects of raiding events determine crop loss are essential when developing and evaluating deterrents. However, because accounts of crop-raiding behaviour are frequently indirect, these parameters are rarely quantified or explicitly linked to crop damage. Using systematic observations of the behaviour of non-hu...

assessment of agricultural drought risk at critical times before and during the growing season can provide sufficient time to policy makers and farmers to implement appropriate strategies to reduce the potential of risk. the purpose followed in the present study is to develop a statistical model to estimate the quality of agricultural drought risk for rainfed barley crop (prior to planting and ...

An approach for estimating human exposure to pesticides via consumption of six important food crops is presented that can be used to extend multimedia models applied in health risk and life cycle impact assessment. We first assessed the variation of model output (pesticide residues per kg applied) as a function of model input variables (substance, crop, and environmental properties) including t...

nitrogen is one of the most important nutrients in crop production, but it's losses to the environment is harmful. the sundial model (simulation model of n dynamics in the soil) was used to quantify the cycle of n and it's losses in different production systems of sugar beet (beta vulgaris l.) in former khorasan province, east of iran. the data were collected from traditional, semi-me...

The risk involved in basing a nematode management decision on predicted crop loss is related to the uncertainty in the crop damage function and error in measuring nematode population density. The sampling intensity necessary to measure a nematode population with specified precision varies with population density. Since the density is unknown prior to sampling, optimum sampling intensity for a m...

Remote sensing bears the potential to provide quantitative information of agricultural crops instantaneously and of a certain regional extent. Estimates of crop growth which are used for crop yield prediction, and timing of forthcoming harvest are important in agricultural planning and policy making. For non-optimal growing conditions, estimates of crop growth may be inaccurate. Crop monitoring...

In the crop breeding process, the use of data collection methods that allow reliable assessment of crop adaptation traits, faster and cheaper than those currently in use, can significantly improve resource use efficiency by reducing selection cost and can contribute to increased genetic gain through improved selection efficiency. Current methods to estimate crop growth (ground canopy cover) and...
