Conclusions
It is however concluded that optimal performance of okra all the year round could be enhanced with compost application at 15 t/ha (C3) coupled with low light intensity (L3). Low light intensity (76% light reduction) increased the growth parameters, but delayed flowering. In combination with higher compost rates, it enhanced prolonged fruiting and leaf formation in the two okra varieties. High light intensity (L1) though enhanced leaf area formation and early flowering, it hastened leaf senescence and abscission. Compost generally increased leaf area and dry matter accumulation of the two okra cultivars compared with control under varying light intensities, with the higher rate (15 t/ha) being superior. Between the two cultivars, ‘Clemson spine’ performed better than ‘NH47-4’ in terms of yield. It grows faster and produces more fruits especially at high compost application.
