| Popis: | Good crop yield entirely depends on good management practice and quality management of crops allied with authentic weather forecasting can reduce risk, crop damage, cost of production and increase the yield as well. Bangladesh Rice Research Institute (BRRI) had aimed this study for quantifying the financial benefit of forecasting and validating micro climatological factors and their impacts on paddy production through experimentation and arranging for weather based agro meteorological advisory service delivery to the farmers applying the tools of ICT. A next-generation meso-scale numerical weather prediction system, WRF (Weather Research and Forecasting) model was used for generating atmospheric simulations based on real data (observations, analyses or idealized conditions). Field experiment was conducted in the areas of five different agro microclimatological conditions for Boro rice production, namely; Gazipur, Habiganj, Rajshahi, Barishal and Satkhira. Then the experimental fields were managed according to the weekly management advisory based on weather forecasts. Results obtained suggest that the application of weather predictability accrued a comparative rice yield benefit of 9-12% and a 3–5% reduction in the cost of cultivation. Countrywide application of agro-meteorological advisory service may pave the way for averting adverse climatic effects on agriculture. |
