introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...

Some researchers report that one potential tool for reducing fungicide requirements on turfgrasses may be the use of silicon (Si) fertilizers. Silicon has been reported to suppress diseases on various crops in the last decade (Raid et al., 1992; Cherif et al., 1994; Deren et al, 1994; Seebold et al, 2000; Seebold et al., 2001). Researchers in North Carolina found that brown patch and dollar spo...

Bio-fertilizers are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. This investigation was aimed at determining the effect of Nitroxin bio-fertilizer application on growth, inoculation and yield production of corn hybrids. An experiment was conducted as split plot on the basis of randomized complete block design with fou...
