Technical Annual Report 2000/01 115 Table 2. Effects of interaction of treatment combinations of plastic mulch/no plastic mulch and hybrid or open pollinated okra varieties on total number and weight (g) of okra harvested and average individual fruit weight (g) of okra produced when grown with a cover crop Total number Total weight ** (g) Average weight * (g) No mulch/Hybrid 800 a 12,533 a 15.71 a No mulch/OP 702 a 13,087 a 18.60 b Plastic/Hybrid 980 b 15,819 b 16.10 a Plastic/OP 815 a 15,566 b 19.21 b Values between pairs of treatments followed by different letters are significantly different (p<0.05). * The significant differences in these columns can be explained by the main effect of variety. ** The significant differences in this column can be explained by the main effect of mulch. Non-cover crop area As with the cover crop area the total fruit number was significantly greater for both plastic mulch and hybrid variety treatments (Table 3). The total weight was significantly greater from the mulch treatment compared with no mulch but not variety. Interestingly a significant difference in average weight was found between varieties only as opposed to the cover crop area, which showed a heavier fruit under mulch compared with no mulch. Table 3. Total number, weight (g) and average individual fruit weight (g) of okra grown on soil without a cover crop Total number Total weight (g) Average weight (g) No Plastic Mulch 593.5 a 9,239 a 15.85 a Plastic Mulch 849.1 b 13,875 b 16.30 a Hybrid 774.5 b 11,408 a 14.66 a Open Pollinated 668.1 a 11,706 a 17.49 b Okra was grown either with or without plastic mulch and either a hybrid or open pollinated variety was used. Values between pairs of treatments followed by different letters are significantly different (p<0.05). When the treatments are compared as a group (Table 4) the results indicated the same response as was found in the cover crop area; however, the actual increases were greater. The benefits of adopting parts of the package were greater when introduced on poor soils. 1. The Plastic/hybrid treatment combination produced the greatest fruit number. 2. The use of plastic mulch produced the greatest harvested weight regardless of variety. 3. OP variety produced the heaviest individual fruit irrespective of whether mulch was used. Table 4.
