RESPONSE OF OKRA (ABELMOSCHUS ESCULENTUS L. MOENCH) TO PHOSPHORUS FERTILIZER IN SOILS OF CENTRAL CROSS RIVER STATE by Attoe, E. E., Agba, A.O. & Ojikpong,T. O.

 Abstract

A pot experiment was conducted at the Cross River University of Technology, Obubra Campus to evaluate the response of Okra (Abelmoschus esculentus L.moench) to Phosphorus fertilizer in some soils of central Cross River State. Soil samples were collected from six (6) locations, namely: Obubra, Ediba, Ekpogreyia (Sandstone), Bendeghe, Okundi and Etomi (Basalt). The experiment was laid out in a randomized complete block design (RCBD) with three replications. Five Phosphorus fertilizer rates (0, 25, 50, 75 and l00kg/ha P205) were applied to the samples. The results obtained showed that there was significant (P > 0.05) response of the Okra to the phosphorus fertilizer with 75kg/ha P205 giving the optimum yield in terms of all the parameters assessed namely; plant height, number of leaves per plant, number of pods per plant and pod weight and is therefore recommended for the zone. There were significant associations between P levels and some of the yield parameters; plant height and number of leaves per plant. Soil suitability rating in terms of pod yield varied within the locations in the order of Etomi > Okundi> Ediba > Bendeghe > Ekpogrenyia > Obubra.

Key words: Phosphorus fertilizer rates, Central Cross River, Okra, Growth and Yield.
