This dispersion of efforts did not hinder that, already in the second half of the decade of 1930, it appeared in Brazil for the first time, even so of still incipient form, an agricultural strategy in the scope of the central government, having as objective to extend and to diversify the farming production of the country, particularly that one destined to the domestic market. The main instrument of this strategy was and would continue to be for much time credits, it agricultural publishes of Creia of the Bank of Brazil. The advantages I credit of it agricultural quickly had been used to advantage by the agriculturists, becoming possible, between 1938 and 1945, not only the great magnifying of the bank credit to the productive sector, but also a considerable growth of the farming production in the same period (SWMRECSANYI; BRANCHES, 1977, p.231).

The period postwar period was called, in the agricultural scope, for the new cycle of valuation of the external prices of the coffee, that if opened in the magnifying deals of it broke world-wide it of 1946, hibernando in this A stage the diversified politics of products and region that prevails in the previous period. The agricultural politics of the federal government in the period basically had been come back toward stimulate the production saw market mechanism to it, with the state intervention acquiring some relevance only at the moments where referring problems to the internal supplying appeared of foods and substances cousins. The exchange, fiscal and credit subsidies for the acquisition of the modern insumos calls of the farming production had contributed substantially for the great increase had in the fertilizer consumption and for the diffusion of the use of tractors and other mechanical equipment, even though of the trucks. These instruments of agricultural politics can be faced as the desencadeante factor of the industrialization of Brazilian agriculture, which started to occur with bigger intensity in the second half of the decade of 1950, also contributing for the great I continue increase that had in offers of products agriculturists entre1946 and 1964.
