live cattle trade for slaughter in Manaus was, until the 1970s, the main economic base. For years, between 6 and 10 thousand oxen were traded with Manaus annually. This type of trade brought foodstuffs, clothing, household items, among others, to Roraima. This form of supply ended due to two main factors: population growth in the state, through the inauguration of the Manaus–Boa Vista Road, and the decrease in the cattle herd. Rice took the place of meat, starting to be traded with Manaus in the late 1970s. In 1977, agricultural mechanization for rice crop was introduced, increasing production capacity. In the beginning, mechanization was applied in the area of plowing for the production of upland rice, which did not have the success expected by several factors. One of them was the lack of physical structure for storing production, as there were no dryers and warehouses. However, this system made it possible to shift production to irrigated rice. With more capitalized producers and government support in the construction of warehouses and dryers, production became viable. This type of rice came to be produced in the floodplains of the Branco, Takutu, Uraricoera and Cauamé rivers, with productivity high enough to cover the high costs of implanting and maintaining this crop in Roraima. Subsequently, the cultivation of soybeans appeared in the plowing, with the planted area being increased year by year. The biggest problems of this crop are in the area of guaranteeing land tenure, its incompatibilities with environmental laws, in addition to irregularity and poor reliability of transport. These two largest crops in Roraima decreased with the conquest by the peoples from the Demarcation of the Raposa Serra do Sol Indigenous Area. Other crops such as corn, cassava and beans are also present. But they do not reach the level of rice and soy production. In the case of manioc for the production of flour, Roraima is self-sufficient. In the area of fruit growing, pineapple, orange, banana, papaya, melon, watermelon, grape, lemon, passion fruit and tangerine are produced in the state. The melon, watermelon and papaya stand out for their quality recognition. There has been great progress with vegetables in recent years. The production of lettuce, green onions, parsley, peppers, sweet potatoes, string beans, pumpkin, cabbage and sweet pepper have increased, and it can be said that there is also self-sufficiency in this sector. Greenhouse production has helped in this process. Roraima
