abstract soil beneficial microorganisms such as plant growth promoting rhizobacteria (pgpr) are able to enhance plant growth. the research was conducted using a randomized complete block design as split plot factorial with three factors (nutrient management, azospirillum and azotobacter strains) .in this experiment the effect of azospirillum and azotobacter inoculation on yield and yield compon...

Sunflower is a potent allelopathic plant which possesses important allelochemicals with known allelopathic activity on other plants. In this study, allelopathic effects of fresh aqueous extracts (FAE) and air dried aqueous extracts (DAE) of root, shoot and leaves of sunflower (Halianthus annuus L.) were investigated on germination and seedling growth of wheat (Triticum aestivum L.) and maize (Z...

Decomposition of wood is an important part of the carbon cycle of nature. Decomposition is caused by fungi, insects, and marine borers that use the wood as food or shelter, or both. Lignin in wood provides a physical barrier to enzymatic decomposition of cellulose and hemicelluloses. This barrier is breached mechanically by insects and marine borers, biochemically by whiteand soft-rot fungi, an...

This study aimed to assess the effects of three plant growth promoting rhizobacteria (PGPR) and chitosan either singly or in combination on maize seeds germination and growth and nutrient uptake. Maize seeds were treated with chitosan and bacterial solution. The germination and growth tests were carried out in square Petri dishes and plastic pots. The combination chitosan-A. lipoferum-P. fluore...

Cultivation of OYSTER MUSHROOM (Pleurotus tuber-regium) on selected organic waste was carried out in the Microbiology Laboratory, Faculty of Science of the University of Port Harcourt. The study evaluated the effect of selected organic wastes on the growth and yield of Pleurotus tuber-regium (Fr. Singer). The organic wastes (Dry Substrates which include Maize cob, Cassava peelings, Plantain pee...

Four fibre crops (hemp, kenaf, maize and sorghum) considered amongst the most suitable for the conditions of Northern Italy were compared in 1995 and 1997, over two irrigation regimes (rainfed conditions and restoration of 100% ETp) and in two locations (Bologna and Milano). Three harvests were carried out on each crop at different development stages. At each harvest time data on yield and yiel...

Copper is a trace mineral that plays an important role in human metabolism, largely because it allows many critical enzymes to function properly. Little is known of copper content of Nigerian foods. In this paper, copper contents of several typical Nigerian foods were determined. The samples were collected from Kanam of Plateau State in central region of Nigeria. The samples were wet-ashed acco...

The seasonal variation of protein and amino acid content have been investigated from leaves, wood and bark of Sesbania grandiflora, Sesbania bispinosa and Sesbania cannabina are the medicinally important plant of Marathwada region (M.S., India). Comparative account of protein contents of leaves, wood and bark of Sesbania cannabina showed higher level (range 3.957 to 5.939 mg/g dry wt.) than Ses...

In this study, effect of salinity with different osmotic potential on shoot length, total fresh and dry weight, amounts of organic (proline) and inorganic (K+ and Na+) substance of leaf tissue, the Na+/K+ ratio, and leaf area, relative water content (RWC) and leaf osmolality in two maize (Zea mays L., var. intendata, C.6127 and DK.623) cultivars which are grown as a second yield in the Southeas...
