Preliminary studies on the response of eggplant (<i>Solanum melongene</i> L) in soils of different parent materials
Abstract
A preliminary experiment was conducted to evaluate the effect of potassium fertilizer on the performance of eggplant in soils of different parent materials in Central Cross River State. The design was laid out in a
split-plot experiment in a Randomized Complete Block Design (RCBD) with three replications.The parent materials from six locations (Bendeghe, Etomi Ekpogrieyia, Okundi, Obubra and Ediba) occupied the main
plot while the potassium levels (0, 25, 50, 75, and 100kgK/ha) was assigned to the subplot. Data on plant height, number of leaves per plant and total dry matter production were collected. The result obtained
showed that the eggplant responded significantly (P <0.05) to the applied potassium fertilizer in terms of the parameters assessed like plant height, number of leaves and between the zero and 25kgK/ha dry matter.
Also there was significant difference in the performance of the eggplant with the soil type. Performance of the crop was in the following order: Basalt > sandstone > shale in terms of parameters assessed. Also 50kg k ha-1 gave the highest yield in most of the locations and was therefore recommended for the soils.
