MAIZE SEED INOCULATION WITH BIOAGENT AND ITS EFFECTS ON THE GROWTH AND YIELD TRAITS
The presented study sought to use the plant growth-promoting microorganism (PGPM) as a biofertilizer in maize (Zea mays L.) seeds and determine its effects on the growth and productivity of maize, with two levels of mineral fertilizer (25% and 50% of chemical fertilizer) under Iraqi conditions. Laboratory studies confirmed no antagonism between Azotobacter chroococcum and other microorganisms used in this study. Field experiments carried out during crop season 2021 were in two different regions, Mosul (36°20′6″N, 43°7′8″E) and Kirkuk (35°28′5.02″N, 44°23′31.99″E) in the north of Iraq. The result showed biofertilizer superiority when combined with 25% and 50% doses of the recommended mineral fertilizer for maize growth and yield traits in the experiments in both locations. In Kirkuk city, the biofertilizer combined with 25% chemical fertilizer recorded superiority without significant difference from the biofertilizer combined with 50% mineral fertilizer. However, in Mosul city, the biofertilizer combined with 50% chemical fertilizer expressed a more superior and significant difference than other treatments for growth and yield traits in maize. The difference between the two regions might be due to chemical fertilizer residues in the soil.
期刊介绍:
The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO).
Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society.
The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards.
The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
