SRI focuses on changing the management of plants, soil, water, and nutrients to create a more productive and sustainable system of rice cultivation. [2] A comparison of SRI grown rice to conventional methods. The methodology has been adopted by millions of smallholder farmers around the world, particularly in Asia and Africa.
Alternate wetting and moderate soil drying reduce cadmium accumulation in rice grains. [8] AWD can dramatically reduce the concentration of arsenic in harvested rice grains. [15] A variant of AWD such as e-AWD practice can reduce grain arsenic, lead and cadmium levels up to 66, 73 and 33% respectively. [13]
Hence, the method and experiment provide sustainable agriculture means in Southern China. Rice production in China is severely constrained by “excessive water consumption, labour shortage, large environmental footprint, and low economic profit” [21] – this makes rice ratooning a favourable practice for production. From the former, rice ...
Puddling is the tillage of rice paddies while flooded, an ancient practice that is used to prepare for rice cultivation. Historically, this has been accomplished by dragging a weighted harrow across a flooded paddy field behind a buffalo or ox, and is now accomplished using mechanized approaches, often using a two-wheel tractor.
Sustainable methods of weed management may help reduce the development of herbicide-resistant weeds. [110] Crop rotation may also replenish nitrogen if legumes are used in the rotations and may also use resources more efficiently. [111] Rotational grazing with pasture divided into paddocks. There are also many ways to practice sustainable ...
Rice polyculture is the cultivation of rice and another crop simultaneously on the same land. The practice exploits the mutual benefit between rice and organisms such as fish and ducks: the rice supports pests which serve as food for the fish and ducks, while the animals' excrement serves as fertilizer for the rice.
Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming—is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop.
The International Rice Genebank holds more than 127,000 accessions of rice and wild relatives and is the biggest collection of rice genetic diversity in the world. [ 25 ] [ 26 ] The International Network for Genetic Evaluation of Rice (INGER) was created by IRRI in 1975 as the International Rice Testing Program IRTP. [ 27 ]
