Hydroponic Cultivation of Tomato
Mineral substrates used in plant hydroponic cultures should have low contents of the solid phase and good, stable air and water properties. Rockwool is a substrate with such properties, and it has been produced for plant culture systems since 1969 by I/S H.J. Henriksen and V. Kähler (Denmark). The aim of the study is to evaluate the effect of an application of increasing manganese (Mn) and boron (B) concentrations added to a nutrient solution on the yielding, content of macro- and micronutrients in tomato leaves and fruits (Lycopersicon esculentum Mill., cv. Alboney F1 and Emotion F1). Plants were grown in rockwool using a nutrient solution with the following content of Mn (mg dm−3): 0.06, 0.3, 0.6, and 1.2 mg dm−3 (Experiment I, 2008–2011) and 2.4, 4.8, 9.6, and 19.2 mg dm−3 (Experiment II, 2012)—designated the symbols for Mn: Mn-0, Mn-0.3, Mn-0.6, Mn-1.2, Mn-2.4, Mn-4.8, Mn-9.6, and Mn-19.2 and for B: (0.011), 0.4, 0.8, 1.6 in the form of Na2B4O7·10H2O (Experiment I) and boric acid H3BO3 (Experiment II) (combinations of the designated symbols, respectively, B-I, B-II, B-III, and B-IV). The influence of Mn and B nutrition on biometric parameters and chemical composition of leaves and fruits of tomato is discussed.
