Effect of differnt soil textural grades and soaker water of organic manure on vegetative growth, flowering and chemical constituents of marigold (Tagetes Patula L.,) plants [electronic resource].

Includes references.

A pot experiment was carried out during two successive seasons of 2006 and 2007 on marigold "Tagetes patula L." plants to study the effects of different texture grades such as sandy, clay, sandy loam, sandy clay loam and clay loam and organic soaker water of poultry manure at the rates of 0.5, 1.0, 1.5 kg soaking, which diluted in 20 liter water for 24 hour and then gave to pot at the rate of 0.5 L. four times per 15 days, on vegetative growth, flowers yield and chemical constituents of marigold "Tagetes patula L." plants. The obtained results indicated that, all plant parameters i.e., plant height, number of branches/plant, herb fresh and dry weight/plant, root fresh and dry weight/plant, number flower, flower fresh and dry weight/plant, flowering%, volatile% and yield/plant, caroteniods of flower, N, P and K% and total carbohydrates% in the herb were more affected by soil texture grades and poultry manure soaker water rates. Sandy soil gave the lowest values of plant characters and chemical constituents than other studied soil textural grades, but it surpassed the clay soil in root fresh and its dry weight/plant as well as flowering %.
