All plants require certain conditions of the environment for their best growth and development. The most important of them are water, soil, sunlight and temperature.
Proper temperature is also essential for crop production. The optimum temperature for germination and growth varies with different kinds of crops. Grain crops such as wheat and barley, for instance, grow at lower temperature than cotton and corn. Many crops are more adapted to the temperature conditions than to colder or warmer environment.

                                       Factors affecting growth
1. The genotype of a plant affects its growth, for example selected varieties of wheat grow rapidly, maturing within 110 days, whereas others, in the same environmental conditions, grow more slowly and mature within 155 days.
2. Growth is also determined by environmental factors, such as temperature, available water, available light, and available nutrients in the soil. Any change in the availability of these external conditions will be reflected in the plants growth.
3. Biotic factors are also capable of affecting plant growth. Plants compete with other plants for space, water, light and nutrients. Plants can be so crowded that no single individual produces normal growth. Optimal plant growth can be hampered by grazing animals, suboptimal soil composition, lack of mycorrhizal fungi, and attacks by insects or plant diseases, including those caused by bacteria, fungi, viruses, and nematodes.
4. Some plants may be organized according to their seasonal growth pattern: annual plants live and reproduce within one growing season, biennial plants live for two growing seasons and usually reproduce in second year, and perennial plants live for many growing seasons and continue to reproduce once they are mature. These designations often depend on climate and other environmental factors; plants that are annual in alpine or temperate regions can be biennial or perennial in warmer climates.

Farm animals are affected by climate, soil fertility, diseases, parasites and man. Beef cattle, hogs and poultry used for meat in the North are quite different from the meat animals bred nearer to the equator.
Animals respond to the factors of the environment. The animals best adapted to the conditions of the environment grow and produce better.

Most of Japan’s land cannot be used for growing crops because it is mountainous. The land that can be used for crop cultivation is used intensively in order to provide people with food.
The best farm land is around Jokohama and Tokyo. The climate and soil here are good for growing crops.
Rice is the most important food for the Japanese people. They grow much rice. It is grown in standing water in fields. When rice is mature the water is drained and the plants are harvested with special machines.
Another very important crop in this country is sweet potato. It is widely grown on the higher lands.
There are also fields of other crops such as wheat, barley and corn.

Many important crop plants complete their life cycle in one growing season. Such plants are known as annuals. Some annuals are spring annuals planted in spring and harvested in autumn. There are also winter annuals planted in autumn and harvested next summer. Winter wheat is an example of winter annuals and corn is a typical spring annual.
Some plants start their growth in one season but produce seed and die at the end of the second season. They are biennials. Sugar beet is a good example of a biennial plant.
Many plants grow for more than two seasons. Most of our hay and pasture crops are perennials.

Electricity has become highly important in our modern world. It has made our work easier and our life more comfortable.
In agriculture electricity is being used in many ways. It is especially widely applied in animal buildings for lighting and for operating different machines such as barn cleaners, feed conveyers, automatic ventilators and automatic waterers.
Electric energy is more economical than any other forms of energy. Electricity operated machines save time and labour, increase labour productivity and improve the quality of work.
