Other claims from this paper (16)
- Association Plant height of Dark Green lettuce increased significantly.
- Association Plant fresh weight, leaf number and seed yield of Balady lettuce increased significantly.
- Association Average weight of 1000 seeds of Balady lettuce increased significantly.
- Association Great Lakes lettuce had the highest number of seed stalks.
- Association Great Lakes lettuce had the maximal percentage of bolting plants.
- Association Great Lakes was the earliest lettuce cultivar.
- Intervention effect Increasing N levels enhanced plant height, fresh weight and leaf number of lettuce.
- Intervention effect Application of 60 kg N/fed. increased the percentage of dry matter of lettuce leaves.
- Intervention effect Application of 60 kg N/fed. gave the highest percentage of bolting plants, seed stalks number and seed yield in lettuce.
- Intervention effect Application of 60 kg N/fed. gave the highest 1000-seed weight and germination percentage in lettuce.
- Intervention effect Balady lettuce seed oil content increased when fertilized with 90 kg N/fed.
- Intervention effect Using GA3 at 50 ppm increased seed stalks number, percentage of bolting plants and seed yield of lettuce.
- Intervention effect Using GA3 at 50 ppm increased 1000-seed weight and germination percentage of lettuce seed.
- Intervention effect Seed oil percentage of lettuce decreased with the application of GA3.
- Intervention effect Balady lettuce fertilized with 60 kg N/fed. and sprayed with 50 ppm GA3 gave the highest seed yield.
- Recommendation Balady lettuce seed oil could supplement or substitute conventional oil types, based on fatty acid composition and physicochemical properties.
