Higher Light Intensity Combined with Early Topping Improves the Yield and Quality of Pea Shoots in LED Plant Factory

Juwen Liang; Fang Ji; Dongxian He Horticulturae 2024. doi:10.3390/horticulturae10060650

Other claims from this paper (13)

Intervention effect Early topping promoted early harvest of pea shoots compared with later topping.
Intervention effect Early topping increased the number of harvested shoots by extending harvest time to 2.8 times.
Intervention effect Early topping gave a substantial yield improvement over later topping.
Intervention effect Lower planting density (ET-LD) gave 8.7% higher yield than higher density (ET-HD).
Intervention effect Average shoot fresh weight under ET-LD exceeded ET-HD by 48.9%.
Recommendation ET-LD is advisable for pea shoot cultivation in LED plant factories.
Intervention effect Light intensity of 150 μmol m−2·s−1 increased AFW by 60.2% over 50 μmol m−2·s−1.
Intervention effect Light intensity of 150 μmol m−2·s−1 increased the number of harvested shoots by 62.8% over 50 μmol m−2·s−1.
Intervention effect Light intensity of 150 μmol m−2·s−1 increased total fresh yield by 165.1% over 50 μmol m−2·s−1.
Association AFW and photosynthetic capacity initially increased and then decreased with the extension of the planting period.
Association Soluble sugar and vitamin C levels in leaves initially increased and then decreased with the extension of the planting period.
Association Light use efficiency and photon yield initially increased and then decreased with the extension of the planting period.
Recommendation Light intensity of 150 μmol m−2·s−1 with a 16 h photoperiod and early topping within 60–70 days suits hydroponic pea shoot production in LED plant factories.
