After harvest growth for three consecutive years, there is still room for China to see grain output increase if the government provides sufficient support, an agricultural expert said Tuesday.

Chen Zhangliang, president of the China Agricultural University, told Xinhua that a 10-percent grain output increase for per mu of lands (about one 15th of a hectare) is predictable this year if the government offers agricultural subsidy and provides technical supports.

"There is still room for an increase of grain yield though many people believe the country's grain production has hit the peak as per unit area yield in some regions has been greatly raised due to the use of chemical fertilizer and pesticide," Chen, a member of the Standing Committee of the National People's Congress (NPC), said on the sidelines of the top legislature's annual session.

China's average unit yield of grain stays at 400 kilograms per mu, and the figure varies greatly in different regions, according to Chen.

"The unit yield in some places is still very low since farmers have no money to buy chemical fertilizer and timely, sufficient irrigation is not secured," he said, adding these regions are where the country can seek potential unit yield increase.

Chen also said that China should not put the quality of grain products over quantity at the current stage.

"If quantity were ignored for the sake of quality, the country's grain security would be threatened," Chen said, adding that "to feed its 1.3 billion people should always be put as a priority for China".

Despite serious natural disasters, China last year saw a rich grain harvest with total output amounting to 497.45 billion kilograms, 13.44 billion kilograms more than the previous year.

Experts attributed the steady increase to farmers' willingness to grow grain due to higher grain prices and the government's preferential policies, such as subsidies for grain growing and the abolishment of agriculture taxes.

However, observers also warned that the country's grain production remains weak compared with its huge population.

The Study Times, a periodical affiliated to the Party School of the Central Committee of the Communist Party of China, predicted that China could face a 4.8 million ton grain shortage in 2010, almost nine percent of the country's grain consumption.

Chinese Premier Wen Jiabao also repeatedly stressed the "high importance" of agriculture at the ongoing NPC session, saying that agriculture, as the foundation of China's national economy, concerns people's life and social stability.

The premier said dwindling arable land and sown area of winter wheat, and warm winter and prolonged drought brought about adverse impacts on the country's agricultural production.
