Effect of Foliar Applications with some Nutritive Compounds on Garlic Yield and its Components in a Sodic Soil

摘要

TWO fieid experiments were carried out at a private farm in Dyarb- Negm, Sharkia Governorate during two successive winter seasons 2005/2006 and 2006/2007 to study the effect of foliar spray application of two organic plant nutritive compounds, which contain micronutrients (Nofatrein and Setrein) at rates of 0, 1.5, 3 and 4.5 l/fed on total yield, quality and components of garlic bulb under alkaline soil conditions. The obtained results indicated that foliar application of each of Nofatrein and Setrein at different rates to garlic bulb led to a significant increases in total yield, exportable yield, marketable yield, average weight of bulb, bulb dry matter N. P. K. Fe, Mn, Zn. content and uptake, volatile oil yield, total carbohydrates and total protein there were significant increases within all treatments. The maximum values of total yield of garlic bulb were obtained from D and H treatments (4.5 1/fed) Nofatrein or Setrein in the l'v/ season reached to 9.7 and 9.92 Mg/fed for while in the 2t/ season were 10.08 and 10.29 Mg/fed respectively, resulting in maximum values of response percent over control in both seasons compared to un-sprayed control. The weight loss percentage of bulbs increased during storage period in both seasons. NO~(-3) content in garlic bulb under different treatments were in the save limits as well as total yield and its components under such alkaline soil conditions.
