Crop Weather Calendars

Crop Weather Calendars for the states viz. Tamilnadu, Andhra Pradesh, Kerala, Himachal Pradesh, Assam, Gujarat, Orissa and Rajasthan have already been published. Up-to-date crop weather calendars for Karnataka, West Bengal, Maharashtra, Bihar and Madhya Pradesh will be published shortly, while that of New Delhi, Punjab and Uttar Pradesh will be started soon. This provide information on crop growth stages, normal weather for crop growth, warnings to be issued based on prevailing weather condition, water requirement of crops during their various phytophases, meteorological conditions favourable and development of crop pests and diseases. This publication is prepared for major crops grown in the states of the country. These calendars are useful for crop planning, irrigation scheduling and plant protection measures.

Information on normal weather conditions, water requirements of crop etc., are of vital importance for effective crop planning and for maximising and stabilising food production in the country. More than two decades back the above information was prepared in a pictorial form,called Crop Weather Calendars, for major cereals,pulses and oilseeds crops in the country on a districtwise basis.

With the recent introduction of new strains by the plant genetic breeders and bio-technologists and the changing scenario in agriculture, the earlier crop weather calendars, have lost much of their utility. It is therefore felt revision of these calendars is necessary in the light of the momentous advancements in different fields of agricultural sciences including agricultural meteorology which have taken place during last two decades.

Keeping in view the current cropping patterns, soil types, the patterns of weather and other factors revised crop weather calendars have now been prepared. These calendars include factors like water requirement of crops during their various phytophases, meteorological conditions favourable for development of crop pathogens.

Information contained in the calendars give broad indications of the direction of development which may prove useful to the planners, agricultural administrators, plant breeders and the farmers in the formulating policy matters regarding plant breeding, crop adoption, drought proofing, supplemental irrigation, maximising the yield etc.
