Effectivity of Pseudomonas fluorescens TBT214 in increasing soybean seed quality in different seed vigor

Abstract

The research aims to assess P. fluorescens TBT214 as biopriming to increase seeds quality. Research conducted in Field Laboratory, Faculty of Agriculture, Halu Oleo University. Research arranged in randomized block designs. The first factor is the level of seed vigor consisting of 2 levels: V1= low vigor seeds (60-65% germination rate), and V2= high vigor seeds (86-100% germination rate). The second factor is the seed bio-invigoration technique which consists of 6 levels: B0=without seed bio-invigoration (control), B1=KNO3 1%, B2= KNO3 1% + P. fluorescens TBT214, B3= P. fluorescens TBT214, B4= P. fluorescens TBT214 + red brick powder, B5= P. fluorescens TBT214 + husk charcoal powder. (B5). So that obtained 12 treatment combinations. The variables observed in this study were (1) The total number of pods, (2) The number of filled pods, (3) the weight of 1,000 grains (g), and (4) Grain production (ton ha-1). The results showed that biopriming treatment could improve seed quality in seeds with low vigor levels or seeds with high vigor. Increasing seed quality resulted in the high potential of pod production, the weight of 1,000 grain seed, and yield. It can conclude that the biopriming treatment can improve the quality of seeds, both seeds with low vigor and seeds with high vigor.
