تأثير الصنف و الرش بسائل جوز الهند و إضافة السماد الفوسفاتي و تداخلاتها في بعض صفات النمو الخضري و الزهري لنبات التيوليب Tulipa hybrid L.

Abstract EN

The present experiment was conducted during the growing season of 2011\ 2012 at the Cloth Home, college of Agriculture, Basrah University, Garmat Ali Campus , with the objective of studying the effect of cultivar and spraying with liquid coconut and the application of phosphate fertilization and their interaction on vegetative growth and flowering of Tulip plant (Tulipa hybrida L.).

The experiment included 18 factorial treatments , which included the interaction of three factors, two cultivars of Tulip (Burgundy Lace and Judith Leyster), spraying with liquid coconut at three concentrations ( 0 , 10 , and 20 % ) and phosphate fertilizer at three levels , 0 , 50 and 100 kg hectare -1 as P2O5 .

Plant of the cv.

Judith Leyster had a significantly higher plant height , length of flower stalk , as well as the percentage of phosphorus in their leaf in comparison with plants of the cv.

Burgundy Lace , whereas the cv.

Burgundy Lace had a significantly flower diameter in comparison with the cv.

Judith Leyster.

Treatment with liquid coconut at a concentration of 10 and 20 % caused a significant increase in plant height , length of the flower stalk .

However, liquid coconut at concentration of 10 and 20 % caused a significant increase in dry weight of the shoot system and flower diameter, leaf carbohydrate content , as well as the percentage of P of leaves.

This treatment also canted earlier flowering .

Treatment with phosphate fertilizer either as 50 or 100 kg hectare-1 as P2O5 , gave significantly height , dry weight of the shoot system , length of the flowering stalk , However , phosphate fertilizer at 100 kg hectare-1 as P2O5 had significantly higher plant height , diameter flower and as well as the percentage of P in their leaves .This treatment also caused earlier flowering .

The secondary and tertiary interactions among the studied factors were significant in most characteristics.
