Abstract

Field and screen house studies were conducted in 2006 and 2007 at the University of Agriculture, Abeokuta, Ogun State, Nigeria to determine the optimum application rate of organo-mineral Fertilizer [OMF] deried from composted sawdust and poultrry manure and fortified with mineral fertilizer for the production of okra [Abelmoschus esculentus]. Treatments used were 0, 2, 5, 0,  7.5, 10.0 t/ha OMF and 200kg/ha NPK 16-16-16 in the screen-house while the above with exception of 10.0 t/ha OMF were used on the field. Agronomic parameters evaluated were plant height, number of leaves, canopy spread, stem girth and fruit weight. Chemical characteristics of post – planting soil were also determined. Highest okra plant and fruit yield [34.83 cm and 138.31g/plant respectively] were observed on plants treated with 7.5 t/ha OMF in the screen house. The above ferrtilizer rate significantly increased the canopy spread and stem girth of okra above the control on the field.
