Effects of nutrient culture solutions on growth and yield of tomato.
Abstract
Tomato plants were grown in pots containing sand and fed continuously by drip irrigation with nutrient solutions made from either analytical-grade salts or commercial fertilizers (having the same concentrations of macro- and microelements in each case). Significantly higher P and Ca concentrations and significantly lower Cl concentrations were found in the aerial parts and roots of plants supplied with analytical-grade salts than in those supplied with commercial fertilizers. Fruit juice also contained significantly more P with the analytical-grade salts. The DWs of aerial parts and roots were significantly higher with the analytical-grade salts and yield was increased 3-fold compared with the commercial-fertilizer treatment. These differences were attributed to the greater purity and solubility of analytical grade salts. Incluye 4 referencias bibliográficas.
