Fig. 4From: Impact of organic fertilization by the digestate from by-product on growth, yield and fruit quality of tomato (Solanum lycopersicon) and soil properties under greenhouse and field conditionsEffects of fertilization types on tomato qualities in field and greenhouse conditions. a: Sugarāacid ratio (SAR), b: soluble protein, c: ascorbic acid (AsA); d: nitrate. Means (Ā±āSE, nā=ā3) with the same letter in the same cultivation condition are not significantly different from each other (pā<ā0.05). CK represents the control treatment with no fertilizer; NPK represents the NPK (14:14:14) fertilizer treatment with 180Ā kgĀ NĀ haā1; D represents the digestate treatment with 180Ā kgĀ NĀ haā1; NPKāD represents the NPK (14:14:14) fertilizer with 90Ā kgĀ NĀ haā1 and 90Ā kgĀ NĀ haā1 of digestateBack to article page
