Taha Department of Horticulture, Faculty of Agriculture, Minia University, Minia, Egypt Abract: The present udy was designed to udy the effect of soil type (clay loam a sayy soils) a three commercial foliar fertilizers (namely, a, each at 0.00, 0.05, 0.1 a 0.2 %) a their combined effect on number of leaves / plant, flowering, bulbs productivity a percentages of N, P a K of leaves of iris plants. The udies was coucted during 2008 / 2009 a 2009 / 2010 growing seasons at the Nursery of Ornamental plants, Fac. Agric., El-Minia Univ., Egypt. Results iicated that clay soil type increased the flowering alk length, the alk diameter, alk fresh a dry weights/plant a fresh weight of inflorescence/plant as well as fresh weights of new mother bulb a bulblets, number of bulblets/plant a leaf content of N, P a K. The different concentrations of foliar fertilizers had significant positive effect on growth, flowering rate a bulbs production, as well as leaf chemical composition parameters (N, P a K %) in the two seasons. Be values were obtained from that treatment of using Manfret at 0.2 %.Applying Manfret at 0.2 % (as a foliar fertilizer) to iris plants grown in clay soil gave the maximum beneficial effect on the number of leaves/plant, flowering parameters a bulbs a bulblets production as well as the highe P percentage in the leaves.

2 MATERIALS AND METHODS This udy was carried out at the Nursery of ornamental plants, Fac. Agric. El-Minia University, Egypt during the two successive seasons of 2008/2009 a 2009/2010 to examine the effect of two soil media types (clay loam a say) a different concentrations of foliar fertilizers on iris vegetative growth, flowering rate, bulbs productivity a chemical composition. Bulbs of Iris tingitana cv. Wedgewood, gm in weight a give pale blue color flowers, were chosen because it is commonly grown in Egypt. Bulbs were planted on November 1 of the two seasons in 25 cm diameter pots (1 bulb/ pot) filled with clay loam or say soil. The experiment focused on two factors, the fir factor is soil media type namely clay loam soil a say soil. The seco factor was the three commercial foliar fertilizers used, namely, a Manfret "B" (each at three concentrations i.e. 0.05, 0.1 a 0.2 %) as well as the control treatment (0.0 %).

Physical a chemical analyses of the used soil are shown in Table 1. The chemical composition of the commercial foliar fertilizers is shown in Table 2. Iris plants were sprayed with the used commercial foliar fertilizers three times after 30, 60 a 90 days from planting in the two growing seasons. On the other ha, the control treatment was sprayed with diilled water. Misrol as a icking agent was used at the rate of 1 cm/l for all foliar fertilizers treatments. The following data were recorded each season: number of leaves/plant, alk length (cm) a alk diameter (mm), alk fresh a dry weights/plant (g), fresh weight of the inflorescence/plant (g) a fresh weight (g) of new mother bulbs as well as number a fresh weight of bulblets/plant. Chemical analysis were made to measure the levels of N, P a K in the leaves before flowering [15]. The obtained data were subjected to the analysis of variance a means were compared using the L.S.D. values at 0.05 using the MSTAT C program version 4 according to Gomez a Gomez [16]. RESULTS AND DISCUSSION Vegetative Growth Characters Number of Leaves /Plant: Data in Table 3 show that there is no significant difference in the number of leaves/plant due to using the different soil types in the two growing seasons. While number of leaves/plant was significantly imulated in response to using the three commercial foliar fertilizers, namely, a Manfret at 0.05 to 2 %. The promotion was associated with increasing the concentrations of each compou. It could be ated that application of Manfret surpassed the application of the other two fertilizers in this connection. Untreated plants gave the minimum number of leaves/plant (6.75 in the fir season a 6.98 in the seco one). The maximum number of leaves/plant was detected on plants sprayed three times with 0.2 % of Manfret (7.98 a 8.10 in the fir a seco seasons, respectively). These results are in agreement with those obtained by Mohamed [7] on Tagetes minuta a Al-Humaid [8] on rose plants. The interaction between soil type a foliar fertilizers was significant. The highe number of leaves/plant (8.11 a 8.23 leaves in the fir a seco seasons, respectively) was obtained from iris plants grown in clay soil a sprayed with Manfret at 0.2 %. 222

Manfret (0.2 %). REFERENCES Bulbs a Bulblets Characteriics: Data in Table 5 iicated that the fresh weight of new mother bulbs, number of bulblets/plant a fresh weight of bulblets/plant were significantly increased by using the clay soil type compared to using the say soil in both seasons. These results are in harmony with those obtained by Manoly [4] on iris, Khalafalla et al. [5] on ornithogalum plants. Foliar fertilizers namely, a Manfret each at three concentrations (0.05, 0.1 a 0.2 %) significantly increased these parameters compared with the control in the two seasons. The maximum values were obtained on iris plants received three sprays at 0.2 % Manfret. As a conclusion, three sprayers of foliar fertilizers, especially Manfret at 0.2 % were responsible for enhancing growth characters a growth of bulbs a bulblets [18, 21-23]. The great influence was obtained from plants grown in clay soil with the high concentration (0.2 %) of Manfret. The contrary action was detected because of growing the plants in say soil without foliar fertilization in both seasons. Chemical Composition of Leaves: Nitrogen, phosphorous a potassium percentages in leaves, as shown in Table 6 were significantly increased as a result of using the clay soil type as compared with that of the say soil type. The obtained data revealed that different concentrations of foliar fertilizers caused significant increases in N, P a K percentages in leaves as compared with the untreated plants. In this concern, an increase in the elements percentage was observed with increasing concentrations of the foliar fertilizers to reach their maximum values at 0.2 %. The maximum values of N were obtained from plants received three sprays at 0.2 % of. The maximum P % in leaves were obtained from plants received three sprays at 0.2 % of Manfret, also, spraying plants with at 0.2 % gave the maximum values of K % in the leaves of iris plants. Similar tres were observed in both seasons. These fiings are in harmony with those obtained by Attia a Aly [10] on iris plants. 1. Van De Ness, A.G.A., Early flowering of Wedgewood iris. Jversi.
