Abstract
The reuse of substrates for more than one growing season is an alternative to reduce production costs. The objective of this work was to evaluate the yield and quality fruits of the cherry tomato (Lycopersicon esculentum) grown in reused substrates. The experimental design was a complete randomized block, with a factorial array of 7 × 2 (seven substrates and two growth periods), with four replications. The seven substrates consisted of different combinations of sand (S), crushed sugarcane (CS) and peanut hull (PH). The substrates used were: S1 = S; S2 = [(2/3 S) + (1/3 CS)]; S3 = [(2/3 S) + (1/3 PH)]; S4 = [(2/3 S) + (1/6 CS) + (1/6 PH)]; S5 = [(1/2 S) + (1/2 CS)]; S6 = [(1/2 S) + (1/2 PH)] and S7 = [(1/3 S) + (1/3 CS) + (1/3 PH)]. These substrates were tested as new (one growth season), and reused (two sequentially growth seasons). The cherry tomato average yield was 9.07 kg m-2 when growth on the new substrates, and 8.44 kg m-2 when growth on the reused ones. The fruit quality was not affected by the reutilization of the substrates. The average values were 6.5 ºBrix for total soluble solids; 0.6 g for citric acid per 100 g for total titratable acidity and 4.2 for pH. A substrate consisting of equal parts of the three components can be recommended as a good growth medium for cherry tomato. All the substrates tested can be efficiently reused, at least once.
