TESTING OF OGALALLA, SOLANA AND GORELLA STRAWBERRY CULTIVARS UNDER POLYETHYLENE MULCHING AND TUNNELS
The Ogalalla cultivars showed no significant difference in total yield and earliness resulting from the mulching and plastic tunnel treatment. Solana showed significant differences in total yield and earliness, and Gorella only in earliness.
Both Ogalalla and Solana cultivars showed the highest yield in tunnels but in Gorella the highest yield was achieved with black polythene mulching.
The Ogalalla cultivar yielded four times as much as Solana in double tunnels and fourteen times as much as Solana in the control plots. Compared with Gorella, Ogalalla yielded three times as much in black and white polythene mulching and seven times as much in control and single tunnels.
