Changes in essential meteorological factors such as temperature, rainfall, cloud cover, and wind speed impact a farmer's decision in crop management such as land preparation, seed sowing, fertilizer application, plant protection measures, harvesting, storage, and transportation as well as in livestock management in operation such as feed management, shelter management, vaccination schedule, reproductive management, and water management. Therefore, this book describes farmers' perception towards agromet advisory services, to assess the impact of agromet advisory services on farmers' decision-making for different farm operations and to obtain the feedback associated with accessibility and usability of agromet advisory services. The study revealed that there was significant treatment effect on the farm operations such as land preparation, seed sowing, scheduling of irrigation, fertilizer application, and spray scheduling of pesticides and herbicides in banana, vegetable, and coconutcultivation followed by the experimental group farmers.
