Protesters were called upon to disperse peacefully, although some of disgruntled crop farmers said they could not agree to the partial acceptance of their demands.
"We have reached an agreement and I believe you will be satisfied," Kosor said, while Polancec added that up to 80 percent of the demands had been met.
Addressing the protesters, who began their rally on tractors outside the Agriculture Ministry building in central Zagreb on Wednesday, Polancec said that the negotiating parties had agreed that the minimum milk price would be HRK 2.20 per litre.
He announced negotiations with the Croatian Bank for Reconstruction and Development (HBOR) and commercial banks on the rescheduling of loans granted to farmers and promised the introduction of measures temporarily banning the import of dairy products, primarily cheeses.
Polancec said that incentives for crops would be fully paid to farmers.
Protest leaders Ivica Miketek, Stjepan Bistrovic and Antun Laslo also called on the protesters to leave Zagreb and return to their homes peacefully.
The government officials said that negotiations on wheat prices would resume on Monday. The crop farmers who were dissatisfied with the outcome of today's negotiations insisted that the price should be HRK 1.25 per kilogram of wheat, and said they were not going to leave Zagreb.
On Wednesday, farmers drove on several hundred tractors to Zagreb from throughout Croatia in protest against the current situation in the agricultural sector. They spent the night in the tractors, and residents of Zagreb brought them food and drink. Students of the Faculty of the Humanities and Social Sciences joined in the protest.
