Usually start at February to early June and July.
Depend on the locations and the weather (should higher than 21 C )

The yields of each environment.
Irrigated rice environments.

Produce 75% of the world's rice

Average yield: 5.4 t/ha
High yield can reach to 8-10 t/ha or more.

Rain-fed lowland environments.

Produce about 20% of the world rice.

Because the environment are difficult so the yields are very low about 1-2.5 t/ha.

Rain-fed upland environments.

Produce about 4% of the world's rice
Reason that cause low yield is it grow at dry land about 1 t/ha.

Role in Human Society

Rice has become one of the three leading food crops of the world and the number one provider of global human per capita energy. In many Asian countries, including China, India, Japan, Thailand,... rice is their main staple food. Rice grains can be cook with different method, beside steaming and boiling, to make many different kind of foods, for example: rice paper, rice vermicelli, rice stick, rice noodles, rice pudding and more.

As the result of that rice has a huge impact not only on the global food bank but also on the global economy.

There are millions of farmers in the world make their living by growing rice, and tens of millions tons of rice are being traded globally every years to support human food consumption .

Conclusion:

jane_vuong147 — 2013-10-21 12:39:53 UTC

In my opinions, rice plants have significant impact on the growth and development of human society. Firstly, it is one of the most consumed food crops in the world, and a main food staple in many Asian countries. Secondly, in provide a large amount of calories and protein with many order vitamins for human, for example: carbohydrate, fibre, calcium and vitamin B-6. Rice provide a more balance diet for human than wheat. And last but not least, Rice can be sustainably grown in a variety of climates and latitudes with high yields, making it highly sustainable crop plants to grow around the world.

Environmental sustainability:

Growing rice is not sustainable because it require a large area and a lot of water. However, it has become more sustainable using the System of Rice Intensification (SRI), which is created by Fr. Henri de Laulanié, S.J. in Madagascar in the 1980s. The system is now widely used all over the world.

According to the USA rice federation, growing rice has become more sustainable and efficient over the last 20 years in the USA alone.

21% decrease in land require to grow 100 pounds of rice
43% decrease in soil loss since 1987
33% reduction in water used per 100 pounds of rice
52% reduction in energy used per 100 pounds of rice
29% reduction in soil methan per 100 pound of rice
