Abstract:
An experiment was conducted with Nagpur mandarin (Citrus reticulata Blanco) during 2017-18 and 2018-19 at AICRP on Fruits (Citrus) Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The qualitative losses during pre- harvest stage hinder the quality production. Recently sunburn is major problem caused due to high temperature and direct solar radiation, which leads to significant economic losses in mandarin yield. An experiment was conducted to assess the study of chemical substances (3% and 5% of Kaolin and MgCO₃) with respective treatments twice in month of September and October on sunburn percentage. The obtained results showed that, GA₃ 15 ppm+ urea 1% and kaolin 5% and 3% respectively foliar applications were effective to control fruit sunburn as well as percentage of South – West, South – East, North – East and North – West direction per tree sunburned fruit as compared to untreated trees. This result was clear detected that effect of kaolin 5% with combination of GA₃ 15 ppm+ urea 1% followed by magnesium carbonate 5% with (GA₃ 15 ppm+ urea 1%) under this experiment conditions.
