Abstract

An experiment on effect of application of chitosan on growth and vigour of mango grafts cv. Alphonso was conducted at Department of Fruit Science, College of Horticulture, Dapoli, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli during the year 2023-24. Seven treatments and 4 replications in Randomized Block Design viz., Tl Control – Soil + FYM (3:1), T2 (Chitosan 0.5 %), T3 (Chitosan 1.0 %), T4 (Chitosan 1.5 %), T5 (Chitosan 2.0 %), T6 (Chitosan 2.5 %), T7 (Chitosan 3.0 %) with the aim to investigate effect of chitosan drenching on growth, vigour and survival of mango grafts cv. Alphonso. The highest survival percentage (99.13 %), height of the grafts (38.10 cm), number of shoots per graft (2.06 nos.), number of leaves per graft (32.13 nos.) leaf area (694.31 cm 2) were recorded in treatment T5 i.e. Chitosan 2.0 %. The maximum stem girth (10.24 mm) found in treatment T7 i.e Chitosan 3.0 %.

Keywords: Chitosan, mango, grafts, survival percentage, vigour, growth
