It was evaluated the influence of a liquid biofertilizer elaborated by organic fruit farmers of the São Francisco River valley (goat manure, cameroon grass, cow blood, ashes, EM4, sugarcane syrup, and water), associated or not with to goat manure on the nutrient values of the aerial phytomass and on initial development of melon

Box 23, 56302-970, Petrolina-PE, Brazil; tamara@cpatsa.embrapa.brFinancial Support: Embrapa and World Bank (Prodetab)It was evaluated the influence of a liquid biofertilizer elaborated by organic fruit farmers of the São FranciscoRiver valley (goat manure, cameroon grass, cow blood, ashes, EM4, sugarcane syrup, and water), associated or notwith to goat manure on the nutrient values of the aerial phytomass and on initial development of melon. Twoexperiments were conducted, using pots of 3.5 dm3, in protected nurseries (on Vertissolo and ArgissoloAcinzentado) with experimental design of blocks with a factorial arrangement 3 x 2, with four repetitions. Thetreatments were combined biofertilizer or conventional fertilization or absence of fertilizer, with the presence orabsence of goat manure. The quantity of biofertilizer was calculated considering the N absorption for the melonculture during the first 35 days of the cycle. Independently of goat manure effect, the melon phytomass onArgissolo presented higher values for K, Mg and Na with the biofertilizer, and higher values of P withconventional fertilization. The highest values of B and Cu and the lowest of N occurred with the presence of goatmanure. On Vertissolo higher values of Ca and Mn occurred in presence of biofertilizer and lower values of Noccurred in the presence of goat manure. A significant interaction occurred only for Mg. The dry weight of theaerial part and roots of the melon culture, as well as the volume of the roots, showed to be higher due to thebiofertilizer, whereas on Argissolo conventional fertilization presented a greater effect.

The use of biofertilizer and goat manure in melon culture in the São Francisco river Valley: II - nutrients of phytomass and vegetative performance.
