Abstract
An experiment was conducted at the nursery of Faculty Agriculture / Kufa University during growing season 2013-2014 to study the effect of foliar Application of Humus and Boric Acid on Growth and Flowering of Freesia. Experiment was adopted in Randomized Complete Block Design ( R.C.B.D ) with three replicates in two factors First three concentration of Fertilizer Humus (0,1.5 and 3) ml.L-1 Second three concentration of Boric acid (0,10 and 20)mg.L-1 and their interaction between them. The means compared using least significant Difference (L.S.D) at probability level 0.05. The resulted showed that spraying Humus at the concentration 3ml.L-1 or Boric acid at the concentration 20mg.L-1 increased significantly growth parameters ( plant height , number of leaves , shoot dry weight , total content of chlorophyll and soluble carbohydrates ,floral stem length , number of inflorescence , number flower , flower diameter and flower primordia) compared with control treatment which gave the least vales . The resulted also showed that spraying Humus at the concentration 3ml.L-1 and Boric acid at the concentration 20mg.L-1 increased significantly growth and flowering parameters ( plant height , number of leaves , number of inflorescence , number flower ) 49.83 cm ,8.33 leaf.plant-1 6.75 inflorescences. Plant -1, 12.00 flowers.plant -1, 20.33 days compared with control treatment which gave the least vales 33.63 cm, 3.00 leaf.plant-1, 2.05 inflorescences. Plant -1, 6.13 flowers.plant-1, 10.00 days respectively.
