EFFECT OF INOCULANT CARRIER ON SURVIVAL OF Rhizobium ON INOCULATED SEED

Role of Plant Growth-Promoting Rhizobacteria and Their Formulation in Biocontrol of Plant Diseases

“…Polysaccharides such as gums, carboxymethyl cellulose, and polyalcohol derivatives are frequently used to alter the fl uid properties of liquid formulations (Paau 1988 ). Materials used in liquid formulations are synthetic medium, sludge, baker's yeast, effl uents, paneer-whey, and vegetable oil (Kremer and Peterson 1982 ;Hoben et al 1991 ;Vendan and Thangaraju 2006 ;Pandey and Maheshawari 2007 ;Rebah et al 2007 ;Albareda et al 2008 ). In an experiment conducted with Rhizobium inoculants, liquid inoculant was found equally effective in comparison to the solid carrier-based inoculants (Gupta 2005 ).…”

Desenvolvimento e rendimento agrícola na cultura da soja (>i<Glycine max>/i< (L.) Merrill) sob diferentes fontes de nitrogênio

“…Pode-se utilizar também vermiculita impregnada com cultivos concentrados em suspensão em azeite. O óleo é previamente aquecido a 120 o C, por 12 horas, a fim de evaporar algum resíduo de água (KREMER &PETERSON, 1982). temperaturas de 28 e 32 o C, e em temperatura de 4 o C, sob refrigeração.…”

Characterization and selection of rhizobia for use as inoculants for groundnuts in Sudan

“…Groundnut rhizobia with a final count of 10^ cells per seed was the most resistant to stress. Kremer and Peterson (1982) further showed that the oil-base inocu lants improved shoot dry weights and nitrogen contents of cowpea sigificantly over the peat-base inoculants, but there was no difference in the mass of nodules. The peat-base inoculants did improve the shoot weights and nitrogen content of cowpea over the control.…”

“…Recently, Kremer and Peterson (1982) cited Vincent's work that lyophilized rhizobia applied to seeds in aqueous suspensions survive more poorly than rhizobia applied in other forms. In an attempt to im prove the survival of rhizobia by minimizing the effects of heat and desiccation, the authors suspended rhizobia in a nonaqueous carrier (soybean or peanut oil heated at 12l°C for two hours to evaporate excess moisture).…”

“…While peat-base carriers are the popular form of inoculants in the United States (Burton, 1976), encouraging results were recently obtained with the oil-base inoculants (Kremer and Peterson, 1982). These authors further stated that the oil-base inoculant used in their inoculation trials increased the resistance of the applied rhizobia to stress condi tions.…”
