Abstract

The studies on the decomposition of coir waste by yeast slurry and Pleurotus Sojar caju showed that it was found to decompose the coir waste effectively. The nutrient analysis of the decomposed coir pith showed that the Pleurotus decomposed coir pith (PDCP) recorded a higher nutrient status than the yeast slurry decomposed coir pith (YDCP). The effect of decomposed coir pith, biocontrol agents and Plant growth promoting Rhizobacteria (PGPR) based potting media on forest tree seedling disease and their growth was studied. Furthermore, the various combinations of normal nursery mix and P. Sojar caju decomposed coir pith (PDCP) used were 0:100, 25:75, 50:50 and 100:0. The media with equal proportions of normal media mix (NMM) and (PDCP) at 50:50 recorded maximum germination in forest tree seeds, viz., Eucalyptus (Euclayptus tereticornis), Silk cotton (Bombax ceiba). The treated seeds with Trichoderma viride were sown in a PDCP 50:50 ratio along with the amendment of Pseudomonas fluorescens+ Azospirillium + Phosphobacteria @ 10 % (v/v) were recorded the maximum shoot and root growth in both the seedlings of silk cotton and eucalyptus and also resulted in a minimum disease incidence of 2.36 and 1.36 percent in Eucalyptus wilt (Fusarium oxysporum) and silk cotton root rot (Verticillium albo-atrum), respectively. These findings highlight an eco-friendly approach to disease suppression in forest nurseries, offering a sustainable alternative to chemical fungicides.
