Gen Pracha said this was the outcome of negotiations between Agriculture and Cooperatives Minister Yukol Limlaemthong and representatives of rubber farmers from all regions on Wednesday at Government House.
He described the outcome as "satisfying".
Most representatives were happy with the result, but four or five left disappointed. Farmers in the North and Northeast had jointly announced that they would not join in the threatened nationwide protest rally next Tuesday, he said.
Protesting planters in Nakhon Si Thammarat's Cha-uat district did not send their representatives to Wednesday's talks, he said. The protest in Cha-uat entered was in its seventh day on Thursday.
If the protesters in Cha-uat district were happy with the negotiation result, they would eventually disperse. But if not, crowd control police would not be ordered in to break up the rally, Gen Pracha said.
"We will not impose a law to disperse the protest, and no weapons will be used. On Aug 23, 50 officers were injured and one of them suffered a torn ligament after they tried to remove tents at the rally site," Gen Pracha said.
Asked what the government would do if the protest in Cha-uat is prolonged, he said many people in the area had suffered greatly from the blockade of the main southern highway and the railway.
"Many schools have been closed and people who are seriously ill cannot be taken to hospitals because of the road blocks," he claimed.
"Farm produce cannot be delivered to the markets and the people in Cha-uat want the protesters to move their rally somewhere else," the deputy premier said.
Agriculture and Cooperatives Minister Yukol said the meeting with rubber farmers' representatives on Wednesday went well and most of them were happy with the result, to a certain extent.
"I cannot guarantee that there won't be a mass protest on Sept 3 but I believe that the situation will ease up," Mr Yukol said on Thursday.
He said the farmers who are not satisfied with the negotiation result should understand that the government has ideas about how to raise their income. But the government could not accept the demand that it guarantee the raw rubber sheet price at 92 baht per kilogramme, because that would affect the market mechanism.
"Thailand does not set rubber prices. If you think that we can set the prices freely, they would be pushed down even further.
"There is a large amount of rubber in stock. If we set the price at 100 baht/kg and the outcome does not turn out as predicted, who will be held responsible?"
On Wednesday, Mr Yukol and rubber growers' representatives agreed that the government woud pay compensation of 1,260 baht per rai for each rubber growing household, with the limit is set at 10 rai per household.
Mr Yukol said the demand that the government increase the limit to 25 rai per household, would be discussed by the Natural Rubber Policy Committee.
