Rice Production Technology

 

Rice is the most important staple food in the world, and it has been produced for thousands of years. The process of rice production is a very complicated one, which includes breeding, planting, cultivation, harvesting and processing. This paper will discuss some of the methods used in growing rice and how they affect the quality of the final product.

Preliminary work on growing rice began some ten thousand years ago in China. In those days there was no practical way to store seeds, so farmers had to plant them immediately after harvest. They also had to plant a second crop every year because it was difficult to find enough land on which to grow enough rice for their families' needs.

The Chinese discovered that if they planted their seedlings in trenches filled with water and fertilizers, they could produce three or four harvests from a single plot of land each year. Today this method is still used by farmers in parts of Asia where nature does not provide enough rain for irrigation purposes.

There are many types of varieties available today for growing different types of rice (see table). Some varieties can be grown

Rice production is a challenging task. Rice is a food staple that has been consumed by people for thousands of years. Cultivation of rice has been refined over the course of human history. Today, rice production technology has advanced significantly, with the result that many farmers can now produce more food on less land and with less effort. This article provides an overview of how rice is produced and harvested in one of the most important crops in our diet.

Rice is a grain that comes from the grass Paspalum scrobiculatum (known as "field pea" in some parts of India) or another close relative known as Panicum miliaceum (known as "rice grass"). These plants are grown primarily for their seeds, which are used to make pulp for paper mills; however, they can also be used for animal fodder (especially poultry feed), and some species have been used to make ethanol fuel from their starch. The grain itself consists of two distinctive parts: the endosperm (which makes up 80% of the volume) and the mesocarp (which makes up 20%). Both parts contain amylopectin, a complex carbohydrate polymer with a high degree of polymerization (greater than 100).

Rice production technology is the science of growing and harvesting rice. The main objective is to increase yields, reduce costs, minimize environmental impact and ensure food security.

Rice production technology has advanced rapidly over the last 150 years due to improvements in irrigation and fertilization, improved varieties, increased yields, mechanization, better management practices and better communication between farmers and scientists. However, even with these advances there are some problems that remain unsolved including:

1. The use of pesticides for pest control in paddy fields (which may affect the health of humans and animals) can be harmful to the environment;

2. Pesticides cause damage to plants by killing living organisms as well as still-living ones;

3. Water pollution occurs when pesticides are washed into streams or groundwater;

4. Organic matter is used as a fertilizer but it decomposes slowly causing an imbalance between plant nutrients and oxygen in soil;

5. Heavy rains wash away organic matter leaving only mineral salts behind which can result in poor water quality in rivers or streams

Rice production technology is a combination of science, economics, and social values.

The environmental impact of rice production is one of the major concerns in agriculture today. Rice farmers in South Asia are faced with an increasing threat from waterlogged soils, salinization and soil erosion. The high level of salinity in the soil results in crop loss due to high rate of crop growth retardation. The high organic matter content in soils has resulted in slow decomposition rates which leads to shrinkage of topsoil volume by about 30% per decade. This problem has been addressed through integrated pest management (IPM), which involves monitoring all pests present on rice crops at regular intervals so that timely control measures can be taken against them before they cause damage or death to plants.
