Abstract: Peach replant disease (PRD) is a complex syndrome typified by stunted growth and reduced yields in repeated cultivation of peach in old orchard sites. PRD is associated with several biotic and abiotic causes; its symptoms are vague and highly variable by sites under different environmental conditions; making it difficult to diagnose and overcome. In this experiment; we studied the effect of different replant soil treatments for controlling PRD in site preciously planted to peach for >30 years. We compared six replant soil treatments including 3 variants viz., soil fumigation, PGPR and biocontrol in 5 different combos and a control (i.e. Recommended package of practices); each with four replications. The different soil management practices significantly (p<0.05) affected leaf nutrients content of peach plants grown in a replanted site. The results from this study provide evidence that combined treatment (Soil fumigation +PGPR +Biocontrol+25% more of recommended SSP) helped improving the total mineral nutrient status and thus may alleviate replant problem in peach.
