Studies on flowering behaviour of mango Cv. Alphonso under changing climatic conditions of Konkan region

Field experiment was conducted at College of Horticulture, Dr. Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli, Dist. Ratnagiri, (MS) during 2019-2020 at different location to study the flowering behaviour of mango Cv. Alphonso. The field experiment was carried out at three different locations viz., L1: Centre of Excellence for Mango, College of Horticulture, Dapoli, L2: Central Experiment Station, Wakawali and L3: Goa Mankur plot, College of Horticulture, Dapoli. The experiential results showed that the early initiation of flowering was recorded at L1- Centre of Excellence for Mango, Dapoli on 14th January 2020 followed by the location of L3- Goa Mankur plot whereas L2- Central Experiment Station, Wakawali recorded late initiation of flowering during the experimentation. The highest flowering density (63.07%) was found at L1- Centre of Excellence for Mango while that of L2- Central Experiment Station, Wakawali showed lowest flowering density (59.62%). L1- Centre of excellence for mango recorded maximum total number of flowers (1503 nos.) and per cent male flower (90.25%), while L2- Central Experiment Station, Wakawali recorded maximum percentage of hermaphrodite flower (12.00%). The maximum flower panicle length (30.2 cm) and panicle width (21.0 cm) was recorded at L2-. Central Experiment Station, Wakawali. Based on the present study, it was observed that the average temperature, tree vigour, vegetative and reproductive growth, geographical location and many other factors play a vital role in flowering behaviour of mango Cv. Alphonso.
