COMPARISON OF THE EFFECTS OF MANURE-BASED PRODUCT AND AMMONIUM NITRATE ON MAIZE (ZEA MAYS L.)

Abstract

The storage and application of huge amounts of deep litter manure could be a serious issue generated by livestock systems. As broiler litter has high N and fiber content, pre-treatment is strongly recommended. Composting is one of the key method of pre-treatment. Due to Georgakakis and Krintas, 2000, Hosoya composting system is suitable for composting by-products with unfavourable properties such as poultry litter. The end-product (composted and pelletized poultry litter (CPPL)) is appropriate alternative to the substitute for chemical fertilizers, due to its pathogen-free, safe-to-use features and high organic content while it meets the requirements of the European Green Deal's goals. In the frame of research maize (ZEA MAYS L.) plant test was carried out to get information about the effects of CPPL and ammonium nitrate (AN) fertilizer in pot experiment conditions. Measurements cover the following analyses: the length of the roots, stems, and seedlings, the dry matter content, germination percent, Vigour-index, and chlorophyll and carotenoid content. On the whole, it can be stated that CPPL had higher stimulating impacts on measured parameters (root length, dry matter content, Vigour index) in comparison to AN with higher N content.
