Abstract
The effect of four soil biofertilizers, i.e., Biogine, Phosphorine, Rhizobacterine, and Microbine and the bacterium, S. marcescens applied singly or in combinations with oxamyl on M. incognita infecting peach plant as well as N, P, and K status and total chlorophyll content was carried out. All materials tested were variable in improving growth of peach seedlings infected by M incognita. S. marcescens alone significantly surpassed other treatments in increasing number of shoot. branches and leaves, percentages of whole plant fresh weight and shoot dry weight with values of 10.0 and 245.7; 99.5. % and 112.7 %, respectively. Among the four biofertilizers studied, Biogine was ranked first but second to S. marcescens in increasing growth of whole plant fresh weight' and shoot dry weight, followed by
. oxamyl. Whereas, Rhizobacterine : alone gave the least values of such criteria (1.2 % and 2.9 %, respectively). Single application of Oxamyl and Phosphorine significantly performed the highest values of nitrogen (N) in peach plant infected with M incognita, whereas greater increase in potassium content (K) was recovered with oxamyl, Biogine or S. mercescens. Microbine alone gave the highest value in phosphorus (P) (0.412_ ppm). All materials used significantly induced high total content in chlorophyll
. . values within the treated peach plants. However, Rhizobacterine singly or integrated .. with oxamyl overwhelmed all. treatments . in suppressing population densities of M incognita, followed' by S: mercescens or Biogine when applied singly or integrated
. 'with oxamyl. Moreover,' all . treatments significantly suppressed number of galls and egg masses. It was concluded that Biogine applications achieved the remarkable values for controlling M incognita as well as improving peach plant growth parameters.
