Other claims from this paper (18)
- Intervention effect Coconut coir wick troughs (WCC) promoted greater lettuce root length and shoot diameter.
- Intervention effect Pine bark wick troughs (WPB) produced shorter lettuce plants than the other two treatments.
- Intervention effect NFT reduced lettuce leaf area by 83% relative to WPB and WCC.
- Intervention effect NFT reduced lettuce root volume by 44% relative to WPB and WCC.
- Intervention effect NFT reduced fresh shoot mass of lettuce by 58% relative to WPB and WCC.
- Intervention effect NFT reduced dry shoot mass of lettuce by 24% relative to WPB and WCC.
- Intervention effect Fresh root mass of lettuce under NFT was 67% smaller than under WCC.
- Intervention effect Fresh root mass of lettuce under NFT was 59% smaller than under WPB.
- Intervention effect Root dry mass of lettuce under NFT was 35% lower than the average of WPB and WCC.
- Observation Electrical conductivity in the substrates increased over time in the wick troughs.
- Observation Nutrient concentration in the substrates increased over time in the wick troughs.
- Association Lettuce yield and plant quality were higher in the WCC wick system.
- Association WPB substrate EC was two times greater than WCC substrate EC, indicating salt accumulation.
- Observation The pH of the nutrient solution and substrates remained stable over time.
- Recommendation Water and nutrition management of self-compensating troughs needs to be optimized to avoid rising substrate EC.
- Association Nitrate-N and ammonium-N concentrations in lettuce shoot and root differed among treatments at the end of the experiment (P < 0.01).
- Association Phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese and zinc concentrations in lettuce shoot and root differed among treatments (P < 0.01).
- Association Chloride, sodium and bicarbonate concentrations, and the same nutrients, in the substrate and NS differed among treatments (P < 0.01).
