Resumo: | The experiment was installed in a coffee crop (variety Catuaí Amarelo, spacing 4,0 x 0,7m and 6 years) located in Lavras/MG, previously cultivated in a conventional management. After the first year of agroecologic transition the effects of organic and conventional managements in the nutrition and productivity were evaluated. Experimental design used was the lattice balanced 4x4 with five replications in factorial scheme 3x2x2 and four more additional treatments. Three sources of organic matter were used (castor bean bran, bovine manure and boiler litter) with or without straw of fermented coffee, and with or without the green manuring with (Cajanus cajan L.), in the line spaces of the coffee crop and pulverizations with the biofertilizer “supermagro”. The conventional management had the application of ammonium sulfite and the potassium chloride, and conventional foliar manuring. The used organic management is efficient in the supply of N, P and the K for the coffee plant in production. The best sources of N for the coffee plant in the first year of agroecologic transition are the castor bean bran ant the broiler litter, while the bovine manure shows more efficiency in the P supply. The treatments of organic managements show productivity similar to the conventional, due to the existence of nutrient reserves in the soil. |
