Wheat Yield and Weedness under Different Rate of Nitrogen Fertilization

Effect of nitrogen fertilization on yield,protein and amino acids of irrigated mexipak wheat

Efficiency of nitrogen fertilization in spring wheat

An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...

Remote Sensing of Biomass and Yield of Winter Wheat under Different Nitrogen Supplies

Since N content may promote changes in the VI vs. LAI relationships, the interpretation of VI as a function Vegetation indices derived from reflectance data are related to of fIPAR instead of LAI could be more appropriate. canopy variables such as aboveground biomass, leaf area index (LAI), and the fraction of intercepted photosynthetically active radiation Furthermore, the interpretation of VI...

A Novel Remote Sensing Approach for Prediction of Maize Yield Under Different Conditions of Nitrogen Fertilization

Maize crop production is constrained worldwide by nitrogen (N) availability and particularly in poor tropical and subtropical soils. The development of affordable high-throughput crop monitoring and phenotyping techniques is key to improving maize cultivation under low-N fertilization. In this study several vegetation indices (VIs) derived from Red-Green-Blue (RGB) digital images at the leaf an...
