SPECTRAL EVALUATION OF THE EFFECT OF POULTRY MANURE PELLETS ON PIGMENT CONTENT OF MAIZE (ZEA MAYS L.) AND WHEAT (TRITICUM AESTIVUM L.) SEEDLINGS

In my research I observed the effects of different poultry manure pellets on germination and pigment changes in maize and wheat with breeding test. At the end of the experiments I measured the pigment and spectral data. The effect of the pellets on the pigment content was also studied by Tukey's variance analysis and I evaluated the connection between pigment content and reflectance. Then based on the spectral data, principal component analysis was performed to select the appropriate wavelength ranges. In the case of maize, the Natur extra and Nitro-plusz poultry manure pellets produced outstanding results on sandy soil and we can raise. In the case of wheat, the P+K manure pellets produced outstanding results. The absorption of chlorophyll can be measured at 678 nm and chlorophyll b at 650 nm. When we carried out the principal componenet analysis, we could select the 520-650 nm wavelength range and 700 nm wavelength for maize. For wheat the wavelengths were 540-650 nm and 702 nm. The priority ranges and their proximity ranges may be suitable for spectral monitoring of the pigment content.
