Title StatementProduction and use of rhizobial inoculant
General NoteCollege, Laguna: University of the Philippines Los Banos, BIOTECH, 1994. 145 p
Summary, Etc.The effectiveness of inoculation in acid soils was continued on pot experiment, acid tolerant mungbean nodulated well with both acid tolerant and intolerant rhizobia. The acid tolerance of the strains contributed more to their survival and persistence in their soil than to their affinity with the host cultivar of a similar acid tolerance level. In green house experiments, liming increased the inoculum strain population in the soil and the rhizosphere of mungbean and inoculant application in granular form improved inoculum survival and effectiveness. Thirteen out of 43 peanut rhizobia isolates showed tolerance to acid-aluminum stress in a defined liquid medium. Selected acid tolerant isolates showed better survival in the soil. The survival of introduced rhizobia on mungbean, soybean and peanut seeds was assessed in field experiments in three locations. The number of rhizobia that survived on the seed after sowing was much lower than what was initially applied. Irrigation before or soon after planting prevented the reduction in the population of the rhizobia on the seed up to four hours after planting. Thus, a need to evaluate management practices or inoculation methods that will minimize the rapid decline of rhizobia on the seed. The persistence of introduced strain was also studied in a pot experiment and in rice-based cropping systems. One year after inoculation of a soil from Pasuquin, Ilocos Norte, the inoculum strain had a nodule occupancy of only 18%
