Abstract:
The effect of shading on fruit yield and quality of two tomato cultivars was investigated during the late summer season.
The results are summarized as follows:
- Shading of plants significantly increased the number of fruits per plant and total yield.
The maximum fruit yield was obtained by plants grown under 35% shading.
- Shading of plants significantly improved the physical characteristics of tomato fruits.
The highest weight, length diameter and volume of fruits were obtained from plants grown under 35% shading.
- All shading densities used led to a significant increase in the percentage of titratable acidity, whereas, an opposite trend was recorded for total soluble solids and ascorbic acid content of fruits.
- Shading also led to a significant reduction in the percentage of sun-scald fruits.
The highest percentage of puffy and blotchy ripening fruits were detected by plants grown under full sunlight and heavy shading (63%).
