PARIS/SYDNEY, Oct 30 (Reuters) - U.S. soybeans rose 0.5 percent on Monday as dry weather across South America pushed prices to a five-day high.
Corn edged higher for the first time in four sessions, while wheat was little changed.
The most active Chicago Board Of Trade March soybeans were up 0.44 percent at $9.79-1/2 a bushel by 1209 GMT, near the session high of $9.81-1/2 a bushel - the highest since Oct 25. Soybeans gained 0.4 percent on Friday.
Analysts said soybeans were drawing support from fears dry weather in Brazil and Argentina could curtail production from two of the world's largest exporters.
"This situation combined with a good export activity (from Brazil) and a rising demand from China supported soybean prices," consultancy Agritel said in a report.
Brazilian farmers have sown 30 percent of the soy area through Thursday, roughly in line with a five-year average, but more than 10 percentage points below planting at the same time in the previous year's crop, consultancy AgRural said on Friday.
The decline in Argentine soy planting area should stop next year, when the government plans to start cutting its 30 percent tax on bean exports, the country's two main grain exchanges and a farmer in bread basket province Buenos Aires said this week.
The most active corn futures were up 0.1 percent at $3.49 a bushel, having closed down 0.5 percent in the previous session.
The most active wheat futures were down 0.2 percent at 4.26-3/4 a bushel, having closed down 1 percent on Friday.
Wheat is under pressure amid weak demand for U.S. supplies.
The International Grains Council lifted its forecast for 2017/18 world grain production on Thursday, mainly due to an increased estimate of the U.S. corn crop. (Reporting by Colin Packham; Editing by Christian Schmollinger and Mark Potter)
