CLIMATIC REQUIREMENTS OF PLANTS
Man cannot influence climatic conditions However, with new progress science, crop production can be controlled by applying improved farming practices.
So, the farmer cannot regulate the amount of rainfall, but he can prevent loss of moisture by proper cultivation and by incorporating into the soil large amounts of organic matter which helps conserve moisture. In some areas irregularities in rainfall and lack of moisture are compensated by irrigation.
Proper temperature is also essential for successful plant growth. In addition it helps conserve water in the soil, so some plants grow best in so cool climates not only because of direct effect of temperature, but due to higher supply of water under such conditions.
Wind is another climatic factor influencing crop production. The farmer cannot control the wind, but he can farm his land in such a way as to lose as little soil as possible due to wind erosion. He can plant winter crops in areas where they will mature before dry, not windy weather becomes a problem the next summer....

Additional information

Sunlight is highly important for many processes taking place in the growing plant. There exists a relationship between length of day and the flowering and fruiting of plants. Some plants produce flowers only when days are long and nights are short. They are called long-day plants. Some plants produce flowers and fruit in autumn when days are short and nights are long. They are called short-day plants. Some plants are not likely to be affected by the length of the day.
Crops vary in their climatic requirements. Com can he grown under a variety of climatic conditions, the most favourable environment being the one where the average summer temperature is between 70° and 80°F.
Wheat sown in the fall does best in regions where the climate is cool and moist during the fall, winter and early spring months followed by warm and dry harvest period. Low yields may often result from loo low temperatures and abnormally dry weather. Wheat and com may sometimes be grown in rotation with each other, because wheat is a winter and spring crop, and com is a summer crop. Like potatoes, oats and barley do best in cool, moist climate .Both quality and yield of potatoes arc better in cool regions. Vegetables, because of their high adaptability, are grown under different soil and climatic conditions, soils of good physical properties being especially important
To obtain high yield of a good quality crop it is necessary to select a proper variety best adapted to the conditions of the region it is to be grown in.
