Abstract
Two field experiments were conducted in 2001/2002 and 2002/2003 seasons at Sakha Agricultural Research Station, Kafr-EI Sheikh Covemorate to study the effect of transplanting technique and soil application of boron and zinc on yield and its components of sugar beet crop sown at two dates. The present work included twenty treatments represent the combination between five sowing technique of sugar beet (1.Sowing sugar beet by dried seeds-direct sown, 2. Transplanting by paper pots seedling of 15 days age, 3.Transplanting by paper pots seedling of 25 days age, 4.Transplanting by paper pots seedling of 35 days age, S. Transplanting by seedling resulted from the permanent field at thinning time.) and four micro-nutrient treatments i.e. : Unfertilized treatment as control, 0.5 kg boron/fed "recommended dose", 4.0 kg zinc/fed " recommended dose" and 0.5 kg boron + 4.0 kg zinc/fed.). All treatments were applied for sugar beet sown at two sowing dates (15th September and 15th October). Sowing sugar beet early on the 15th September significantly attained higher values of total soluble solids %, sucrose %, purity 0/0 compared with that obtained at the late sowing date, 15th October. On the contrary, sowing sugar beet on 15th September significantly reduced the values of potassium %, sodium %, juice impurities % in sugar beet roots compared with late sowing on 15°' October. All of alpha-amino nitrogen %, zinc and boron concentrations in roots or leaves of sugar beet were unaffected by sowing dates. The highest values of sucrose %, potassium %, TSS %, purity %. Was obtained from transplanting seedling of 15 days age and/or sowing beet seeds by the usual method (dry seeds). However, these two methods of planting lowered the values of potassium % in roots. Application of zinc element alone or in combination with boron element significantly resulted in higher values of sodium and zinc contents in sugar beet roots and leaves compared with those recorded with the unfertilized or with boron alone. Application of boron alone or in combination with zinc produced higher TSS %, sucrose %, boron concentration in sugar beet roots and leaves compared with those recorded by the unfertilized with zinc alone.
