Abstract
Irradiance level is a limiting factor for plant growth, especially in a greenhouse. A bacterial fertilizer was applied to test its role on cucumber seedlings to overcome low light intensity. Five light intensity levels of 100, 200, 400, 600 and 800 μmol⋅ m−2s−1 were used. The results revealed that the bacterial fertilizer can stimulate nitrogen (N) and potassium (K) uptake at 400 and 600 μmol⋅ m−2s−1 and phosphorus (P) uptake except for 800 μmol⋅ m−2s−1. Nitrogen, P, and K in soils were highly improved at various light intensities. The effect of promoting iron (Fe) and zinc (Zn) was stronger in roots than in shoots. The significant improvements of chlorophyll, carotinoid, soluble sugar, and photosynthesis rate were also observed. The bacterial fertilizer increased plant height, stem diameter, leaf area, fresh and dry weight except for the decline of height at 100 and 200 μmol⋅ m−2s−1. The sharp decline or increase occurred mostly at the light intensity of 400 μmol⋅ m−2s−1.
