Abstract
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.
