Okra yield fertilized with bovine manure and biofertilizer

Abstract

The use of bovine manure becomes an useful and economic practice for the small and medium producers of vegetables, and the okra plant normally demands high doses of organic fertilizers. This study was carried out, from January to July 2011, at the Federal University of Paraíba, in Areia city - PB, aiming to evaluate the effect of bovine manure and biofertilizer on the productive behavior of the okra plant. The experimental design used was randomized blocks, with four repetitions in factorial scheme 6 x 2, with the doses factors of bovine manure (0, 10, 20, 30, 40 and 50 t ha-1) with and without biofertilizer. The average mass of commercial fruit of okra, with and without biofertilizer was 18 and 16.5 g, respectively, in the doses of 27.5 and 60 t ha-1 of manure. The number of fruit plant-1 without biofertilizer was 30 fruits plant-1 of okra in the dose of 60 t ha-1 and with biofertilizer, the number of fruits plant-1 was 33 fruits in the dose of 28 t ha-1 of bovine manure. The productivity of commercial fruits of okra without biofertilizer was 20.4 t ha-1 and 22 t ha-1 with biofertilizer, respectively, in the doses of 60 and 31 t ha-1 of bovine manure.
