Abstract:
An investigation was carried out to research the influence of jasmonic acid along with different organic mulching materials on fruit quality parameters of mango cv. Himsagar in West Bengal’s new alluvial zone. The experiment was set up by using Randomized Block Design with four replications along withfive treatments viz. T₁ (Jasmonic acid @ 0.5 μM+ Geotextile mulch @ 500 GSM), T₂ (Jasmonic acid @ 1.0 μM + Paddy straw mulch), T₃ (Jasmonic acid @ 1.5 μM + Banana leaf mulch), T₄ (Jasmonic acid @ 2.0 μM + Black polythene mulch), T₅ (Control-Water spray). Experimental findings revealed that JA is effective in increasing physico-chemical qualities of mango and reduces disease infestation on storage. Among different treatments, T₂ was proved most effective in improving physico-chemical characteristics as well as post-harvest qualities of mango. This treatment also exhibited minimum disease infestation on storage with maximum shelf life at ambient temperature. Finally, it was concluded that Jasmonic acid @ 1.0 μM along with Paddy straw mulch applied at flowering stage can be applied for quality fruit production of mango to achieve a noble goal.
