The carbon count of 2000 years of rice cultivation

Global Change Biology, 2012
AbstractMore than 50% of the world's population feeds on rice. Soils used for rice production are mostly managed under submerged conditions (paddy soils). This management, which favors carbon sequestration, potentially decouples surface from subsurface carbon cycling. The objective of this study was to elucidate the long‐term rates of carbon accrual in

Rotavation and Rice Cultivation

Madras Agricultural Journal, 1953
It is a known fact that the low yields of irrigated paddy are in a large measure traceable to late sowings and the same may also be said in the case of this State where predominantly rice growing areas exist and the vagaries of the monsoon do not allow the fields being got prepared for the timely sowings.

Origin, dispersal, cultivation and variation of rice

Plant Molecular Biology, 1997
There are two cultivated and twenty-one wild species of genus Oryza. O. sativa, the Asian cultivated rice is grown all over the world. The African cultivated rice, O. glaberrima is grown on a small scale in West Africa. The genus Oryza probably originated about 130 million years ago in Gondwanaland and different species got distributed into different ...

Wild and Cultivated Rice

Nature, 1947
The systematics of rice is, as systematists will agree, a matter of more than academic or departmental interest. The improvement of this important cereal depends on its sound classification. To this end the remarks of Dr. D. Chatterjee1 seem to fall short of what is needed.

Impact of Rhizospheric Microbiome on Rice Cultivation

Current Microbiology
The rhizosphere niche is extremely important for the overall growth and development of plants. Evidently, it is necessary to understand the complete mechanism of plant microbe interactions of the rhizosphere for sustainable and low input productivity. To meet the increasing global food demand, rice (Oryza sativa L.) agriculture seeks optimal conditions.

Rice cultivation in ancient Amazonia

Nature Ecology & Evolution, 2017
Emerging research suggests ancient Amazonians employed a range of cultivation practices to develop diversified diets, rich in both wild and domesticated plant and animal resources. Southwestern Amazonia is now understood as a major centre of plant domestication.

Botany of the Wild and Cultivated Rices

Nature, 1947
ALTHOUGH much work has been done on the widely cultivated species of rice (Oryza sativa Linn.) for its improvement as an agricultural crop, it must be admitted that our knowledge of its morphology and taxonomy and its relationship to other wild species of the genus is comparatively meagre.

INNOVATIVE AGRONOMIC TECHNIQUES FOR RICE CULTIVATION

2004
Flooded irrigation is usually adopted for rice growing in temperate areas. The efficiency of this method is generally very low and water consumption is comprised on average between 13 and 20.000 m3 ha-1, with maximum values reaching over 50.000 m3 ha-1.
