Produtividade, acúmulo de nitrato e estado nutricional de cultivares de alface, em hidroponia, em função de fontes de nutrientes
Provedor de dados: 75
Autores: Fernandes,Adriano Alves; Martinez,Herminia Emilia Prieto; Pereira,Paulo Roberto Gomes; Fonseca,Maira Christina Marques.
Foram avaliados a produtividade, acúmulo de nitrato e estado nutricional das cultivares de alface Regina, Babá de Verão e Grandes Lagos em cultivo hidropônico. O experimento foi conduzido no outono, de 25/03 a 20/05/99 em estufa da UFV. Foram avaliados dois conjuntos de fontes de nutrientes para compor as soluções nutritivas de crescimento vegetativo, que continham: 13,6; 1,0; 7,0; 4,48; e 2,5 mmol L-1 de N, P, K, Ca e Mg, respectivamente. O enxofre foi fornecido na concentração de 3,5 ou 2,5 mmol L-1 e os micronutrientes nas concentrações de 45; 32; 46; 2; 0,9; e 0,2 mmol L-1 para Fe, Mn, B, Zn, Cu e Mo, respectivamente. A solução 1 forneceu 21,9% de N na forma amoniacal, e a solução 2, 100% de N na forma de nitrato. As fontes de P empregadas foram...

The objective of this work was to evaluate the toxicity of organic farming‑compatible products to the coffee leaf miner Leucoptera coffeella. Lime sulphur, enriched Bordeaux mixture (Viça Café Plus), and the "supermagro" biofertilizer were first tested in laboratory. The most promising product was tested afterwards under field conditions. In laboratory, different concentrations of each product were applied on L. coffeella eggs and on infested coffee‑mined leaves. Only lime sulphur had ovicidal effects at an acceptable concentration (1.6%) for field applications, but no significant effect on larvae mortality was found. Enriched Bordeaux mixture and the "supermagro" biofertilizer had no effect on L. coffeella eggs and larvae. In the field trial, biweekly or...

ABSTRACT: Intercropping of vegetables and medicinal plants might produce favorable interactions for both crops, resulting in increased production and profit per unit area. It is known that active compounds can change because of several factors, including the cropping system. Therefore, the goal of this study was to evaluate the effect of intercropping of lettuce and marigold on the productivity of these crops and on the flavonoid content of marigold flowers. The experiment was conducted in the experimental area of EPAMIG in Oratorios-MG. Treatments consisted of lettuce + marigolds intercropping between rows, lettuce + marigold intercropping between plants, and monocultures of each species. Spacing was 0.3x0.3m. The experimental design consisted of...
