Interactions between green manure and rock phosphate on corn production in family farms

ABSTRACT The aim of this study was to analyze whether the use of green manures in association with rock phosphate rates can guarantee corn yields to family farmers. An experiment was conducted with six types of green manures: Mucuna cinereum, Crotalaria juncea, Crotalaria ochroleuca, Cajanus cajan, Pennisetum glaucum and a weedy fallow control treatment; and three rates of phosphorus (0, 50 and 100 kg P2O5 ha-1) in a complete randomized block design. The management with Crotalaria juncea achieved the highest dry mass yield (39.3 Mg ha-1) and in year 2 (2016), with the water deficit during the ...
