The objective of this study was to examine the effect of calcium humate, boron humate, and humic acid solutions on growth, yield, quality, and calcium and boron uptake of tomato (Lycopersicon esculentum L.) and cucumber (Cucumis sativus L.), as well as changes in soil nutrient status after crop harvest. | Turkish Journal of Agriculture and Forestry http://journals.tubitak.gov.tr/agriculture/ Research Article Turk J Agric For (2015) 39: 613-632 © TÜBİTAK doi:10.3906/tar-1406-59 Growth, yield, and calcium and boron uptake of tomato (Lycopersicon esculentum L.) and cucumber (Cucumis sativus L.) as affected by calcium and boron humate application in greenhouse conditions 1, 2 1 1 Melek EKİNCİ *, Aslıhan ESRİNGÜ , Atilla DURSUN , Ertan YILDIRIM , 3 4 5 Metin TURAN , M.

Four different concentrations (500, 1000, 3000, and 5000 mg kg–1) of calcium humate (12% CaO, 15% humic and fulvic acid), boron humate (10% BOH4, 15% humic and fulvic acid), and humic acid (15% humic and fulvic acid) were used in this research. The results revealed that Ca humate, B humate, and humic acid treatments applied at different rates positively affected the total marketable yield, average fruit weight, fruit diameter, fruit length, and leaf dry matter of tomato and cucumber plants. However, no statistically significant differences were observed among the treatments in terms of total soluble solids, fruit dry matter, chlorophyll, and plant .
