Enhancing the Accuracy and Temporal Transferability of Irrigated Cropping Field Classification Using Optical Remote Sensing Imagery
irrigated field classification Landsat NDVI time series Gaussian mixture model interannual climate variability regional analysis
2023/12/1
Mapping irrigated areas using remotely sensed imagery has been widely applied to support agricultural water management; however, accuracy is often compromised by the in-field heterogeneity of and inte...
Reducing nitrogen surplus and environmental losses by optimized nitrogen and water management in double rice cropping system of South China
Nitrogen use efficiency N management Water management N surplus Environmental N losses
2023/4/21
Optimized agronomic management improves nitrogen (N) use efficiency in crop production. However, limited information exists about the effect of improved agronomic practices on the N surplus in double ...
Long term cropping and selected parameters of 15 apple tree cultivars
Malus domestica Borkh tree vigour yield efficiency tree performance spurring habit
2018/3/6
Fifteen apple cultivars registered in the Czech Republic were included in this comparative study. The most productive
after eight years of cropping was ‘Rucla’, which had a mean yield of 50.9 t/ha. T...
Precocity and a long-term cropping in apple progenies grown on M 9 rootstock
Malus × domestica cropping progeny segregation apple breeding
2016/12/8
The fruiting of 23 apple progenies, in total 756 genotypes grafted on M 9 rootstock, was evaluated for 11 years (2005–2015). The most precocious was the progeny obtained by the crossing of genotype HL...
Upgrading the RIM Model for Improved Support of Integrated Weed Management Extension Efforts in Cropping Systems
Adoption agriculture bioeconomics decision support system
2015/12/23
RIM, or ‘‘Ryegrass Integrated Management,’’ is a user-friendly weed management software that
integrates long-term economics. As a model-based decision support system, RIM enables users to

No-Till No-Spray Future Symposium on Nonchemical Weed
2015/12/23
Reduced-tillage systems including no-tillage and stripillage have well-known benefits for conserving and improving
soils, protecting vulnerable crops from extreme weather
events, and reducing ...
Cover Crops for Weed Management in Southern Reduced-Tillage Vegetable Cropping Systems
Alternative weed control conservation agriculture
2015/12/23
With growing agricultural demands from both conventional and organic systems comes the need for sustainable practices

Extreme Grain-Based Cropping Systems: When Herbicide-Free Weed Management Meets Conservation Tillage in Northern Climates
Blade roller fl exible crop production syste low-input cropping system
2015/12/23
The challenges associated with the adoption of conservation tillage and/or low-input cropping systems, whether organic or
herbicide-free, across Canada are shaped by scale, environment, and local pra...
Weed Ecology and Nonchemical Management under Strip-Tillage: Implications for Northern U.S. Vegetable Cropping Systems
Tillage vegetable crops weed control
2015/12/23
In northern U.S. vegetable cropping systems, attempts at no-till (NT) production have generally failed because of poor crop
establishment and delayed crop maturity. Strip tillage (ST) minimizes these...
