INFLUENCE OF ENVIRONMENT ON RATAUL MANGOES

Stonny, water logged and alkaline soil conditions checks its growth and it does not perform well beyond 7.5 pH. However, the plant can withstand in slightly alkaline soil and water logging conditions. Gravelly or “shore” or excessive nitrogenous land should be avoided for Rataul plantation. There should not be high humidity, rain or frost during flowering of Rataul variety. Temperature ranged from 24o-35oC, 50-60 ft. water level suitable for Rataul variety and 75-285cm rainfall is well suitable for Rataul mango variety. Higher temperature during fruit development and maturity gives better quality fruits of Rataul. In frequent showers and high humidity, Rataul variety is prone to many pests and diseases.
