This document presents a project on analyzing the environmental impact on rice yield patterns in Dinajpur District, Bangladesh. The objectives are to observe climate variability over 10 years, find relationships between weather parameters and rice yields, and determine interrelationships among weather parameters. The methodology will analyze data on 6 weather parameters (temperature, rainfall, humidity, air velocity, sunshine hours) collected from agricultural institutions using Excel and develop statistical models using SPSS regression. Previous related studies on the effects of temperature and humidity on rice yields are also presented. The future goal is to help predict rice yields and develop adaptive rice varieties.

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.

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.
