describe the climatic suitability for rice
Answers
Climate and Soil requirement of Paddy Crop Cultivation. Rice is a crop of tropical climate. However, it is also grown successfully in humid to sub-humid regions under subtropical and temperate climate
Climate and soil for rice cultivation
Climate and soil
Rice can be cultivated under different climatic conditions and soil conditions. Rice comes in different types of soil. For general development, the pH range of 5.0-8.0 is suitable.
Various climatic factors affecting rice cultivation are many varieties of rice which are cultivated with the difference of climate factors, such as:
The rain
Rain is one of the most important weather elements for successful cultivation of rice. Distribution of rainfall in different areas is affected by the physical characteristics of the terrain, the condition of mountains and plateaus.
Temperature
Temperatures are another climate factor that is favorable and in some cases there is adverse effects on rice growth, development and yield. Due to the presence of rice tropical and sub-tropical plants, high temperature is required, which ranges from 20 ° C to 40 ° C. During the day, the optimum temperature of 30 degrees Celsius and more favorable for the development and development of 20 ° C rice crop during the night. . Rice cultivation is conditioned by temperature parameters at various stages of development. The average average temperature for flowers and fertilization ranges from 16 to 200 c, while, during ripening, the range is 18 to 320 C. Temperature exceeding 350 C affects the filling of grains.
Day length or sunshine
Sunlight is very important for plant growth and development. In fact, the sunlight is the source of energy for the plant's life. Rice yield is affected by solar radiation, especially during its previous 35 to 45 days. The effect of solar radiation is deeper where water, temperature and nitrogenous nutrients are not limited to factors. The bright sunlight helps in the development of carbohydrate in the grain with low temperature during the harvesting period of the crop.
Three seasons for rice cultivation
There are three seasons to grow rice. These three seasons are named as crop harvesting season.
Sharad Rice / Pre-Kharif Rice
Summer Rice / Rabi Rice
Winter rice / kharif rice
