| Abstract | ||
| A study on the effect of foliar spray of chelated calicum on Antirrinum majus plants and planting in different growing media on vegetative growth and flowering wrer carried out on fall season / 2014 at the lathhouse of to Hort. Dept./College of Agric./ University of Baghdad. Plants were sprayed twice with 0, 1.0, 2.0 g/l of calicum. The growing media tested were five composed of soil :spent mushroom (Agricus bisporus) substrates (SMS). Results can be summarized as follow: Plants treated with 1.0 g/l of calcium responded positively. The treatment improved most of vegetative and flowering characters, Significant incrense was acheived in plant height (21 cm), number of leaves / plant (69.8), number of branches / plant (58), chlorophyll content (170.1 mg/l) and wet and dry weight (25.8, 1.12g) respectively. The treatment significantly incrensed number of influrescences / plant (23) and wet and dry weight (3.04 , 1.19 g.) as well. The best results on vegetative growth improvement were recorded when plants were cultured in 50% Soil + 50% Soil: SMC medium plant height reached 19 cm. number of leaves/plant 67.9, Leave area 3.04 cm2, number of branches / plant 44, chlorophyll content 165.7 mg/l and wet and dry weight 19.3, 0.9 g. respectively. While flowering characters were responded when plants were cultured in 25% Soil + 75%. Soil: SMS medium (M4), the highest value of number of inflorescences / plant (22) , flowering was earlier (71 days), prolonged flowering period was to 24 days and wet and dry weight were 3.31, 2.01g. All interactions between the two factors were positively affected on improving characters tested. | ||
