A simple spectral index using reflectance of 735 nm to assess nitrogen status of rice canopy
Spatial distribution of canopy N status is the primary information needed for precision management of N fertilizer. This study demonstrated the feasibility of a simple spectral index (SI) using the first derivative of canopy reflectance spectrum at 735 nm (dR/d|735) to assess N concentration of rice (Oryza sativa L.) plants, and then validated the applicability of a simplified imaging system ...

The ecologically optimum application of nitrogen in wheat season of rice–wheat cropping system
Because excessive application of N fertilizer for crop production leads to environmental pollution and low N utility efficiency, a better understanding of the effects of N application rates on crop yields and NO3–N leaching is required for developing optimum ecological N management that reduces NO3–N leaching while keeping crop yield. Field experiments at two sites in the Taihu region of China ...

Farmonaut For Crop Area and Yield Estimation
INTRODUCTION: CROP AREA ESTIMATION The two components of agricultural production estimation are crop area and yield estimation. In order to estimate yield, Producers generally measure the amount of a particular crop harvested in a sample area to estimate crop yield. The harvested crop is then weighed, and the entire crop production of the area is approximated from the sample. A method for ...

The developing world is awash in pesticides. Does it have to be?
Herbicides, insecticides and fungicides threaten the environment and human health in many parts of the world. But research is pointing to a better approach. In today’s globalized world, it is not inconceivable that one might drink coffee from Colombia in the morning, munch cashews from Vietnam for lunch and gobble grains from Ethiopia for dinner. That we can enjoy these products is thanks, ...
