CAETANO, Luiz Carlos Santos and CARVALHO, Almy Junior Cordeiro de. Effect of boron and cattle manure fertilization on yield productivity fig tree and on soil properties. Cienc. Rural [online]. 2006, vol.36, n.4, pp.1150-1155. ISSN 0103-8478. http://dx.doi.org/10.1590/S0103-84782006000400017.
The objective of the present work was evaluate the effect of fig tree orchard fertilization with boron and cattle manure on the green fig yield and soil chemical properties. The treatments were five boric acid levels (0, 20, 40, 60 and 100g plant-1) combined with two cattle manure fertilization levels (without cattle manure and 10kg of cattle manure/plant). The experimental design was that of randomized blocks in a split-plot scheme and four repetitions. The boric acid fertilization did not affect the fig productivity whereas the cattle manure one increased it. The P and K content increased significantly and the Al content decreased significantly in function of the cattle manure fertilization. The B soil content, extracted by hot water methodology increased linearly in function of the boric acid levels.
