Abstract
aCollege of Agric.- University of Baghdad from March/ 2005 to March/ 2006 to investigate the effect of agrotonic fertilization levels, type of water and planting date on growth, flowering and flower content of TAGETES ERECTA from some carotenoids pigments . Highest level of the fertilizer 6 g/ L incareased height of plants 73.53 cm., No. of branches/ plant 3.28, main stem diameter 7.76 mm. and the percentage of N, P, K either in leaves or flower. The treatment 6 g/ L elevated No. and flower diameter as well 3.75 , 7.49 cm. respectively. While the intermediate of fertilizer level (4 g/ L) fastened flowering date 161.07 days . The lowest level (2 g/L) increased dry matter percentage of vegetative growth 28.48%. The highest level of fertilizer was effective on elevating flower content from Beta- carotene and lutein pigments. The pigments content was maximized on 6 g/ L level on fresh flower 21.31mg/ 100g. and on dry flower.25.27 mg/ 100 g . Magnetized water was superior on most parameter tested. Optical increased on plant height 69.40 cm , No. of branches/ plant 3.04, stem diameter 7.55 mm. and percentage of N, P, K on vegetative growth. Magnetized water increased No. and diameter of flower, fastened flowering date and dry and fresh wet flowers content from Beta- carotene and lutein 19.05, 23.35 mg/ 100 g. respectively. Planting dates were not effective on all parameters studied
