ABSTRACT:

Clemson spineless and NH-47-H okra varieties were inoculated with Okra mosaic virus (OkMV) at 2weeks after planting. The objective of the experiment was to assess the effect of OkMV on growth, yield and proximate composition of the okra varieties. The experiment was laid out in a Complete Randomized design (CRD) with five replications in the screen house. Data were collected on plant height, number of leaves, pod length and pod weight. The fruit pods at harvest were subjected to proximate analysis using AOAC (2000) methods and all data collected subjected to analysis of variance (ANOVA). The results indicated that OkMV infected plants were significantly (P ≤ 0.05) shorter (13.2cm-19.4cm) than healthy plants (32.6cm – 33.9cm). Clemson spineless inoculated with OkMV averaged the significantly (P ≤ 0.05)lowest number of leaves (12.0) compared to healthy NH-47-H (23.6). The fruit length and weight were also significantly (P ≤ 0.05) lower in OkMV inoculated Clemson spineless (3.9cm and 2.4g) compared with healthy NH-47-H (10.3cm and 8.6g) respectively. Analysis of nutritive content revealed significant(P ≤ 0.05) depletion in the composition of ash, crude protein, crude fat and crude fiber composition in OkMV inoculated plants. The study revealed the damaging potential of OkMV on the two okra varieties and suggests OkMV management to enhance crop growth and nutrition.
