Abstract
The current study was aimed to isolate and diagnosis Bacillus mucilaginosus and evaluate its use as biofertilizer alone or interfere with Glomus mosseae on growth and yield of corn (Zea mays L.) Randomized completely block design was used at the Field of College of Agriculture- University of Baghdad Al-Jadriya in silt clay loam soil. The biofertilizer was used alone or as combination that added with or without 50 Kg P ha¹ of rock phosphate and with or without 120 Kg K ha¹ while, 250 Kg N ha¹ was added as urea (46%N) to all treatments. Results showed the superiority of bacterial or fungal biofertilizer on enhancing all growth traits of corn and the addition of B . mucilaginosus together with Glomus mosseae resulted superiority for plant height , dry weight of vegetative part , grain yield and biological yield with the values 229.4 cm , 180.7 gm .plant¹,12.17 tons ha¹ and 19.59 tons ha¹ respectively. As well as treatment gave significant increase equal the increase in the yield due to addition of completely recommended mineral fertilizer which was 12.14 tons ha-1 .
Highlights
Some studies indicated the important role ofThe optimum use of soil microorganisms micorrhiza fungi in improving water relations activities are an important step to increase the and increase plant resistant to drought [41], available of nutrients for plant and Glomus mossase is one of the most important develop the agriculture, Biofertilization is a and most dispersal in soil [55]
It was found that potassium of its high efficiency in dissolving potassium dissolving bacteria Bacillus mucilaginosus and grown on Aleksandrov broth medium at produce numbers of enzymes such as nuclease, 28 for 3 days .The infected roots and soil endoglucanas,cellobiase,protease,ribonuclase with spores of Glomus mosseae inoculum was and phosphomonoestrase which some of its do added at depth 5 cm in the holes while important role in potassium release mechanism Bacillus mucilaginosus was added to the peat
Without Rock phosphate With Rock phosphate researchers [12] mentioned that inoculation researchers [3,28] mentioned that potassium with potassium dissolving bacteria resulted in has direct influence on controlling plant an increase in grain yield of corn in Hormones which has relation with flower comparison with control treatment since grain formation,its inoculation and fruitfulness . this yield is a final result of all growth and result came in agreement which results development of plant [46]. suitable potassium obtained by some researchers [7,9] which is nutrient enhances nitrogen compounds the same significant for rock phosphate translocation in grain crops and its simulation addition
Summary
The optimum use of soil microorganisms micorrhiza fungi in improving water relations activities are an important step to increase the and increase plant resistant to drought [41], available of nutrients for plant and Glomus mossase is one of the most important develop the agriculture, Biofertilization is a and most dispersal in soil [55]. There are This study was carried out at the field of the different microorganisms which have an Research Station -College of Agriculture important role in the geochemical cycle of University of Baghdad during2016-2017 in silt different nutrients like nitrogen, phosphorus clay loam soil with chemical ,physical and and potassium and some rhizosphere bacteria biological characteristics have the ability to dissolve potassium [14,15,16,23,25,37,39,54] (Table 1), to study from soil and potassium carrying minerals the effects of Bacillus mucilaginosus as such as mica ,illite and orthoclase by biofertilizer alone or with Glomus mosseae on producing different rock and silicon chelating growth and grain yield of corn (Zea mays L.). Some physical , chemical and biological characteristics of soil before planting
