Developing probiotic beverages without animal protein

Most products enriched with probiotics and protein are made with dairy products. However, consumer demand for plant protein is growing. The nutritional value of these proteins must therefore be improved to be comparable to ...

Drought changes rice root microbiome

Drought can have a lasting impact on the community of microbes that live in and around roots of rice plants, a team led by UC Davis researchers has found. Root-associated microbes help plants take up nutrients from the soil, ...

Training in rice growing system raises yields and well-being

Rice is the world's most commonly grown and consumed crop. It also supports lives and livelihoods, especially in low- and middle-income regions. As such, methods for securing abundant and profitable rice harvests are key ...

Hot nights confuse circadian clocks in rice, hurting crop yields

Rising nighttime temperatures are curbing crop yields for rice, and new research moves us closer to understanding why. The study found that warmer nights alter the rice plant's biological schedule, with hundreds of genes ...

Corals' natural 'sunscreen' may help them weather climate change

Smithsonian Conservation Biology Institute scientists are one step closer to understanding why some corals can weather climate change better than others, and the secret could be in a specific protein that produces a natural ...

Rice

Rice is the seed of the monocot plant Oryza sativa, of the grass family (Poaceae). As a cereal grain, it is the most important staple food for a large part of the world's human population, especially in tropical Latin America, the West Indies, East, South and Southeast Asia. It is the grain with the second highest worldwide production, after maize ("corn").. Since a large portion of maize crops are grown for purposes other than human consumption, rice is probably the most important grain with regards to human nutrition and caloric intake, providing more than one fifth of the calories consumed worldwide by the human species. A traditional food plant in Africa, rice has the potential to improve nutrition, boost food security, foster rural development and support sustainable landcare. In early 2008, some governments and retailers began rationing supplies of the grain due to fears of a global rice shortage.

The name wild rice is usually used for species of the grass genus Zizania, both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of Oryza.

Rice is normally grown as an annual plant, although in tropical areas it can survive as a perennial and can produce a ratoon crop for up to 20 years. The rice plant can grow to 1–1.8 m tall, occasionally more depending on the variety and soil fertility. The grass has long, slender leaves 50–100 cm long and 2–2.5 cm broad. The small wind-pollinated flowers are produced in a branched arching to pendulous inflorescence 30–50 cm long. The edible seed is a grain (caryopsis) 5–12 mm long and 2–3 mm thick.

Rice cultivation is well-suited to countries and regions with low labor costs and high rainfall, as it is very labor-intensive to cultivate and requires plenty of water for cultivation. Rice can be grown practically anywhere, even on a steep hill or mountain. Although its parent species are native to South Asia and certain parts of Africa, centuries of trade and exportation have made it commonplace in many cultures worldwide.

The traditional method for cultivating rice is flooding the fields while, or after, setting the young seedlings. This simple method requires sound planning and servicing of the water damming and channeling, but reduces the growth of less robust weed and pest plants that have no submerged growth state, and deters vermin. While with rice growing and cultivation the flooding is not mandatory, all other methods of irrigation require higher effort in weed and pest control during growth periods and a different approach for fertilizing the soil.
