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.

الملخص EN

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 %.

On the other hand clay loam soil gave the greatest values of previous plant characters and chemical constituents than other soil types.

The organic soaker fertilizer at the rate of 1.5 kg / 20 L.

surpassed the other ones of 0.5 and 1 kg / 20L.

For producing significantly increased in growth parameters, flowers yield and chemical constituents.

Both sandy loam and clay loam which fertilized with organic soaker water were statistically equal in producing significant values of vegetative growth, flowers yield and chemical constituents of marigold plants in both seasons.

So, the highest values of growth, flowers yield and chemical constituents were obtained when Tagetes patula L., plants were grown either on clay loam or sandy loam soil fertilized with soaker water of poultry manure at the rate of 1.5 kg / 20 L.
