Evaluación de tres soluciones nutritivas en el tomate hortícola (Lycopersicon esculentum) en los híbridos pirtro y syta mediante el sistema de slabs

Abstract

The test was conducted in order to: evaluate three nutrient solutions in the cultivation of horticultural tomato (Lycopersicon esculentum Mill) in Syta Pietro and hybrids, using semi hydroponics, using the system Slabs; more than determine the economic efficiency of the treatments. The treatments were six; design divided into factorial arrangement of 3 plots (nutritional solutions) x 2 (hybrid), with three replications .. was used analysis of variance, Tukey tests of significance of 5% was made. Tests least significant difference at 5% and the cost benefit ratio (RBC). The best results were obtained with the nutrient solution S2 (p. 27), the obtained longest plant 90 days (43.60 cm) and 120 days (136.56 cm). The fruits reported greater equatorial diameter, in the fourth production closter (6.22 cm), as in the fifth production closter (6.44 cm) and sixth production closter (6.17 cm); being the most weight in the fourth closter production (125.66 g), fifth closter production (122.73 g) and sixth closter production (116.10 g), so the best returns were achieved both the fourth production closter (3.83 kg / treatment), as in the fifth production closter (3.71 kg / treatment) and sixth production closter (3.54 kg / treatment); consequently reporting the highest total yield (21.67 kg / treatment). Pietro (H1), hybrid reported the highest growth in plant length at 120 days (123.99 cm), as the best equatorial diameter of the fruit in the sixth closter production (5.50 cm), the largest weight fruit in the fifth closter production (114.35 g) and sixth production closter (105,62 g), reporting the highest performance in the fifth closter production (3.65 kg / treatment) and sixth closter production (3.44 kg / treatment), which reached the highest total yield (21.31 kg / treatment). Treatments S2H1 S2 nutrient solution (nutrient solution S2, hybrid Pietro and S2H2 (nutrient solution S2, hybrid Syta H2), reached the highest cost benefit ratio of 0,52, where net profits were 0.52 times the investment
