EFFICIENCY OF CO-INOCULATION PHOSPHATE SOLUBILIZER MICROORGANISMS (PSM) AND PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) ON MICRONUTRIENTS UPTAKE IN CORN (ZEA MAYS L.)
Journal Title: Journal of Advances in Internal Medicine - Year 2011, Vol 2, Issue 1
Abstract
Efficient use of p-solubilizer, plant growth promoting rhizohactoria (PGPR) applied as the biofertilizers is important in corn (Zea mays L.) production to maximize producer’s economic returns and maintain soil and water quality. Therefore, to investigating the effects of organic, chemical, and biological fertilizers (PSM and PGPR) on micronutrient uptake of corn (SC 604 cultivar) a field experiment was conducted during 2007. The experiment laid out as split plot based on randomized complete block design with three replications for each treatment. Three levels of manures (consisting of 1-farmyard manure by 20 Mg.ha-1, 2- green manure by 15 Mg.ha-1and 3-control or without manures) and co-inoculation of PGPR and PSM (inoculated and not inoculated), P (0, 50 and 100 Kg ha-1) and N (0, 50 and 100 Kg ha-1) were considered as main plots and sub plots, respectively. Results showed that effects of organic fertilizers were not significant on micronutrient (Mn, Cu, Fe and Zn) uptake. Furthermore, according to results application of PSM and PGPR together and reduced P application by 50%, significantly increased Zn and Fe uptake compared to other plots with adequate input. Using of biological fertilizers and NPK in green manure plots compared to NP50%K+ PSM+ PGPR treatment significantly increased Zn uptake in corn seeds.
