| Abstract | ||
| This experiment was conducted in Wasit province in Zubaydiah area in two fields have different Soil qualities, first Soil was Silty Clay Loam and other Loam Soil through the autumn of 2014 to study the growth of relationship and holds the grain with Spectroradiomtr device and satellite image measurements under different levels of nitrogen added to maize class Angst Swiss hybrid, was divided each field to two treatments (N1, N2) and ten Replicates by design Split plot design within (RCBD) Randomized Complete Block Design. treatment N1 was recommended fertilizer (250 Kg. N/h) either treatment N2 was Add an extra to the recommendation of fertilizer (300 Kg. N/h) and at the end of the season measured some of plant characteristics (such as plant height , leaf area , dry weight ,yield of grain , weight of 500 grain and the number of grains per Corncobs).And use Spectroradiomtr device in measuring the spectral reflectance to plant maize and NDVI of satellite image and gave us the results significant superiority in Spectroradiomtr measuring device and the NDVI for the treatment of N2 on the treatment N1 and conclusion of this study, the relationship is good between the reflectivity values of spectral device Spectroradiomtr dry weight and holds the grain We found a good correlation between the NDVI values and dry weight and grain holds a strong relationship between Spectroradiomtr device measurements and high nitrogen fertilization | ||
