Resumo

Fertilization using organic compounds is complementary to chemical fertilization, being essential to integrated fruit production. Reports on fig tree (Ficus carica L.) organic fertilization and mineral nutrition are worldwide scarce, especially in Brazil. This experiment aimed to evaluate the effects of cattle manure fertilization on the yield and productivity of the fig tree 'Roxo de Valinhos' in Botucatu, Sao Paulo State, Brazil, during the 2002/03, 2003/04, 2004/05 and 2005/06 crop cycles. Plants aged one, two, three and four year olds received the following cattle manure treatments: control (no fertilizer), 25%, 50%, 75%, 100%, 125% and 150% of the recommended N level for this crop. The evaluated variables were: fruit number, weight and mean diameter, plant yield and productivity. The application of cattle manure increased productivity, yield and fruit number, slightly affecting fruit dimensions. After four years of cattle manure application, the best results were obtained with 76 to 124% of the N level recommended for the fig crop. (AU)
