Abstract

Replant problem is the situation resulting in suppression of growth and poor productivity of the replanted trees on old orchard sites which makes the plantation uneconomical. Peach has short life span of 20-25 years and most of the orchard planted during eighties and nineties have outlived their economic life span and are at the verge of decline. Due to limited land resources and choice of crops for diversification in hill states, orchardists are compelled to replant same fruit crop in old orchard site. However; repeated cultivation of the same plant species on the same field leads to replant problem. The new plantations experience low field survival, stunted, poor growth and death of plants even after few years of plantation. Among the treatments, maximum growth and vigour parameters as well assoil enzymatic activities were recorded with Brassica seed meal fumigation. Soils amended with PGPR had higher microbial activity.

Keywords

Peach replant disease, biofumigation, growth, soil viable microorganism count, enzyme activity

Conclusion

The present investigation it concludes that treatment of Brassica seed meal was most effective on an individual basis to influence the plant growth traits, total viable microbial count and soil enzymatic activities in peach replant sick soil under pot culture studies.
