Abstract Rice (Oryza sativa L.), a staple food for more than half of the world population, is
commonly grown by transplanting seedlings into puddled soil (wet tillage) in Asia. This …

Rice is the principal food commodity for millions of people. Its growing demand invokes for
an enhanced productivity, but with limited land and water resources. Among various biotic …

Upland rice, produced by smallholder farmers, is the lowest‐yielding rice production system.
Drought stress is the most severe abiotic constraint in upland rice. Improving productivity of …

Main conclusion Rapid uniform germination and accumulation of biomass during initial
phase of seedling establishment is an essential phenotypic trait considered as early …

About 90% of rice is produced and consumed in Asia, where the demand for rice is on the
increase due to increasing population. Rice is a semiaquatic plant and grows well under …

Weed competition is a major constraint in all the rice production systems in Africa. In addition
to the costs of weed control, weeds account for yield losses estimated to be at least 2.2 …

Forty rice (Oryza sativa L.) cultivars and breeding lines used in the International Rice
Research Institute (IRRI) upland rice breeding program were evaluated in adjacent weed …

The weed-rice ecological relationship is very complex and dynamic. Weed distribution and
successions are always affected by management and environmental factors. Weed …

Over 30 root and shoot growth traits of nine diverse rice cultivars (cvs) grown under
competitive conditions were analyzed to exhaustively quantify cv differences and identify …

Aerobic rice production systems, wherein rice is dry-sown in non-puddled soil and grown as
an upland crop, offer large water savings but are subject to severe weed infestation. Weed …
