Document:
The Department of Agricultural Meteorology is handling four external aided projects and four state plan board funded projects.
Crop weather relationships studies of major crops viz. rice, pepper etc.
Dissemination of Agromet Advisory Bulletins through direct delivery, SMS, emails, local news paper, farmers’ portal, etc.
The crop-weather-disease relationship is mainly analysing for the diseases viz. leaf blight of rice, sigatoka of banana and mosaic of cowpea and the crop-weather-pest relationship is mainly analysing for the pests viz. leaf roller of rice, pseudo stem weevil of banana and pod borer of cowpea based on the weekly observations.
The observations (Rainfall, Maximum and Minimum temperature, Dry and wet bulb temperature, Sunshine hours, Wind speed and direction, Relative humidity, Soil temperature, Evaporation, Dew etc.) are taken in four times a day viz. 0700 hrs LMT, 0830 hrs IST, 1400 hrs LMT and 1730 hrs IST.
