  • 6. Background of the study They used to look at the sky and asses the weather condition! From the very beginning, farmers used to depend on weather for crop production!
  • 7. Why study environmental Impact on rice yield pattern? At first, nature itself and its change over time, includes the physical impact on the Earth's land, water, atmosphere and biosphere all are related with rice yield. 1990 2007
  • 8. At next, how humans use nature, includes the environmental consequences of increasing population, more effective technology and remotely or indirectly changing patterns of rice as well as crop yield. Finally, environmental engineers need to know what do the farmers think about nature - the way attitudes, beliefs and values influence interaction with nature, especially in the form of myths, religion and science.
  • 9. Climate variability and change present threats and opportunities to the environment and sustainability of food systems, and hence will further affect links between agriculture, nutrition and health.

  • 11. Impact of relative humidity of November month of each year on the yield of Boro rice Impact of air velocity, and sunshine hour of November month of each year on the yield of Boro rice Relationship among the minimum & maximum temperature, sunshine hour, relative humidity, air velocity in Boro season at November IMPACT OF WEATHER PARAMETERS ON THE YIELD OF RICE IN MYMENSINGH DISTRICT (2001-2009) BY Engr. MD. SUMON MIAH B.Sc. In Engg.(Agril) M.S. in Farm Structure(BAU) 2006 Impact of minimum & maximum temperature of November month of each year on the yield of Boro rice RESEARCH FINDING Previous Works done on Similar topic
  • 12. Future Aspect Better understanding on environmental impact will enable us ;  Yield Prediction of rice;  To understand response of various rice varieties to the basic environmental parameters  To develop better adaptive varieties  Help Agricultural Scientists with obtained results in developing new high yield varieties.
  • 13. Objectives of the study  To observe the climatic variability for the last 10 years in Dinajpur district.  To find relationship between environment- parameters and rice grain yield.  To find inter-relationship among the environment- parameters.
  • 14. Assumptions; are to be taken in developing the model  The values of weather parameters were uniform throughout the Dinajpur district.  Fertilizers were uniformly distributed in every year for the same crop.  Irrigation water was uniformly supplied in every year for the same crop.  Management of insecticides, pesticides, etc. were uniform in all years.  Viability of seeds was similar in every year.  Soil fertility was similar in every year.
  • 15. Methodology Climate to crop interactions How can projections of climate-induced changes be linked to rice production? Max. Temperature Relative Humidity Rainfall crop Air VelocitySunshine hrs Min Temperature climate 6 major weather parameters are to be considered

  • 22. Relation between each of the 6 parameters to rice will needed to be derived Inter-relation among each of the 6 parameters will needed to be derived To conduct multiple regressions these relations will further be analyzed and statistical model will be obtained in SPSS Where, Y is the dependent variable , i represents the year, a is the constant and b, c, d, e, f are the regression coefficient. Tmax is the maximum temperature (oC), Tmin = Minimum Temperature (oC)
