Improvement of Rice Crop production

Rice crop requires large amounts of water; Therefore, farmers not only peasant are to creating a way this crop production can be reach its point of fertility and thorough improvement by creating channels of water to promote efficiency, in the availability of rice production .
Mostly, to bring an idea on how create a standing water with distinct nutrient, fishes should be pulled or released in large numbers , into the water where rice grows in other to benefit thus:

Fish eat insects, algae, and harmful pests that collect on the soil, and fish feed on plant branches at the same time.

The second benefit is benefiting from fish waste for soil fertility.

The third benefit is that the fish itself grows and increases in reasonable quantities (as food for farmers or trade).

This movement is known as the "rice/fish culture". After implementing this plan, land production increased by about 20% above the normal limit, in addition to the huge quantities of fish.
The introduction of low-cost technologies, which could be part of the modernization of small-scale irrigation projects, provides another example of the site-specificity of success. Inexpensive treadle pumps have been successful in some countries in extracting irrigation water from shallow aquifers. These pumps have allowed poor farmers to make good use of the available labour in their households and so increase crop production and farm income. The farmer has full control over the timing and amount of this pumped water, which given the effort involved is used sparingly. For example, the area under irrigation by one treadle pump in West Bengal, India, varies between 0.033 and 0.13 ha. Treadle pumps have also been introduced in Africa, including the urban and peri-urban areas of Ndjamena, Chad. Here, the vegetable growers rejected the pumps in favour of mechanical pumps because they could afford the cost of fuel and spare parts. However, in the more remote areas of Sarh, Chad, farmers were content with the treadle pumps and requested more of them . Treadle pumps are intrinsically pro-poor, as richer farmers would not be able to persuade household members to use them. A limitation of treadle pumps is that their use requires spare labour, which may not exist. Women are usually already overburdened. Healthy children could do the pumping, provided it does not interfere with school attendance. Therefore, it is important to assess labour availability before introducing treadle pumps .

Rice is extremely sensitive to water shortage (below saturation) at the
flowering stage. Drought at flowering results in yield loss from increased
spikelet sterility, thus fewer grains.
