The Histroy of Vengurla Mango
This town located on the shores of Maharashtra has often been mentioned as a bustling trade center during its golden past. One of the busiest ports of its times Vengurla Warehouses, Godowns, markets and trading centers. The port was central to many trading activities during history period; refer “History of Vengurla”. The town has been making waves in the recent past more due to its beauty and beaches.
In modern Vengrula one of the places to visit is Regional Fruit Research Station, Vengrula. It is establish in 1957. It is spread in total 63.hectors. Major Activities of the research centre is research and exteresension on Mango, Cashew and other major fruit crops.eve
- Major achievement of this research centre regarding Mango are:
- Collected germplasm of 279 types. That means total 279 varieties of mangos are available.
- Regular bearing variety “Ratna” have been released in the year 1983.
- Technique of stone grafting, soft wood grafting has been standardized.
- Regular bearing variety “Sindhu” with very small size stone have been released in 1992.
- Variety for pickle viz; “Konkan Ruchi” have been released in 1999.
- Planting Alphonso “Kesar” and “Goa Mankur” are profitable and there is a three fold increase in yield of “Kesar” in comparison with “Alphonso”.
- Application of Paclobutrazol for inducing regular and early bearing in Alphonso is standardised and advocated.
- Standardized the stage of harvesting of Alphonso mango to minimize occurrence of spongy tissue.
- Given technique of pruning old unproductive mango orchards.
- For controlling mango hopper it is recommended to spray 0.01% Permethrin 0.0075% Cypermethrin, 0.002% Decamethrin, 0.01% Fenvelrate or 0.1% Carbaryl.
- For reducing occurrence of spongy tissue in mango it is advised :
- To harvest 85% mature fruits.
- To protect the harvested fruits from sunlight.
- Transport of fruits be made preferably during night hours.
- Dip the fruits in 500 PPM solution of ethrel.
- Standardized poly houses for large scale multiplication of nursery plants.
- For controlling top shoot borer of mango recommended to spray 0.01% Permethrin or 0.05% Monocrotophos at the time of new flushes.
- Recommended spraying of 0.03% Dimethoate 15 days prior to harvest of the fruits for control of fruit fly.
- For controlling powdery mildew of mango it is recommended to spray 0.02% Sulphur 0.1% Bavistin or 0.1% Tridemephon or SAN 615 F 0.05% after fruit set and 15 days there after
- For controlling Anthracnose of mango it is recommended to spray 0.1% Bavistin and 1% Bordeaux mixture.
- For controlling Loranthus on mango 1% Glyphosate spraying is recommended.
- Cause of early fruit maturity at Deogad was assessed by calculation of heat units : The total heat units required for Alphonso (750 to 800 DD), Kesar (844 to 899 DD) and Ratna (932 to 977 DD) were equal at both Vengurle and Deogad. However, days required for maturation of fruits were less (20 to 25 days) at Deogad than Vengurle due to production of extra daily heat units (1.55 to l.96 DD) at Deogad than Vengurle.
- Identified the pollinizer varieties for Alphonso mango: Identified Kesar, Ratna and Goamankur as pollinizer varieties for Alphonso mango to increase pollination and fruit set in Alphonso mango. Therefore recommendation has been passed (2001) for plantation of 10 to 15% plants of Ratna, Kesar or Goamankur in Alphonso garden.
- Control of Recurring flowering in Alphonso mango with GA3 spray was standardized: The recurring flowering causes fruit drop from old shoot of various size due to translocation of food at new flowering panicle. For control of recurring flowering in Alphonso mango GA3 50 ppm should be applied at full bloom to mustard fruit set. The recommendation has been given to extension agencies (2001).
- Centre opening for increasing yield of overcrowded Alphonso mango: To increase yield of overcrowded mango and to minimise the incidence of pests and diseases, it is recommended to open the centre of tree canopy and thining of branches during rest period alongwith application of recommended dose of pp333 in subsequent year.
- Pruning for bearing trees : For uniform vegetative shoot, flowering, fruiting and to reduce incidence of mango hopper light pruning (50 cm terminal shoots) during rest period is recommended after every 3 years. (Approved in October, 2002 Hort, Sub-committee).
- Nutrient and growth regulators on fruit set,retention and yield of Alphonso mango : Foliar spray of Urea 2% + NAA 20 ppm + Micronutrient 50 ppm or Urea 2 % + Triacontanol 5 ppm + Micronutrient 50 ppm during pea nut size fruit and 10 days after (2nd spray) is recommended to increase fruit retention in Alphonso mango. (Approved in October, 2002 Hort, Sub-committee).
- Alphonso 900 was observed best clone therefore Alphonso was released for registration purpose in 2002.
- MANGO :
- Off season control of mango hopper. Spraying of synthetic pyrethroids during off season for the control mango hopper was recommended (1991-92 – 1993-94)
- Synthetic pyrethroids were more effective in small dose as compared to organophosphate insecticides (1995-96 – 1996-97)
- Survey of pest incidence on mango was conducted from 1994-95 and more than pest were recorded.
- Insecticidal trial for the control of mango thrips. Spraying of 0.04% monocrotophos 36 WSC or 0.05% dimethoate 30EC was recommended.
- Insecticidal trial for the control of mango mealy bug. Banding of alkathene (400 guage) 30 cm wide strip around tree trunk after mud plastering one metre above the ground level was found more effective. Spraying of 0.05 % methyl Parathion 50 EC was also found effective.
- IPM for mango shoot borer. Removal and destruction of infected shoots along with the larvae. Spraying of 0.05% quinalphos 25EC or 0.01% permethrin or 0.04% monocrotophos 36 WSC or 0.1% carbaryl 50 WP after emergence of new flush two times at fortnight interval.
- Screening of mango varieties against fruit fly and stone weevil. Experiment was stated from 1992-93. It was observed that no incidence of stone weevil observed in “Shindhu” variety. Negligible incidence of stone weevil and fruit fly observed in Alphonso, Ratna and Kesar. 8. Seasonal incidence of mango fruit fly using “Rakshak” fruit fly trap. It was observed that the incidence of fruit fly increased from April-May and reached maximum in June-July. Population of fruit flies was more in rainy season.
- For control of mango hopper, “Mango blossom protection schedule” was prepared and recommended.
- Control of mango fruit flies. Spraying with 0.03% dimethoate 30 EC 15 days before harvest of mango fruit was recommended.
- Control of mango leaf miner. Spraying of 0.01% permethrin 10 EC or 0.04% monocrotophos 36 WSC or 0.1% carbaryl 50 WP on emergence of vegetative flush.
- Integrated pest management of mango hopper and blossom midge. For hopper management IPM with pesticide and control with pesticidal sprays alone were found equally effective. As far as midge fly is concerned, the results are not much indicative.
These are the achievement as far as the mango fruits is concern by Regional Fruit Research Station, Vengrula.
Vengurla is tourist most favorite destination, Out of Sindhudurga Distict (Tourist District Declare by Maharastra Government) . Vengurla have natural beaches and greenery and clean environment. In olden days Vengurla was famous for T.B. sanatorium. Due clean and healthy environment in earlier days T.B. patient treated here.
One of the earlier days Vengurla was famous for mission hospital, even from Goa people use to visit Vengurla for treatment pre independent days. Now days Vengurla is famous for Alphonso mango. It is highly production of this crop among the Taluka of Sindhudurga. It is to make brand “ Vengurla Hapus” like “Ratanagiri Hapus” or “Devgad Hapus”
