| Abstract | ||
| Two field experiments were conducted in 2001/2002 and 2002/2003 seasons at Sakha Agricultural Research Station, Kafr-El Sheikh Governorate 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, 5. 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 (151' September and 15ih October). The obtained results showed that sowing sugar beet early on 15th September significantly attained higher values of growth traits as well as sugar recovery %, root, top and sugar yields/fed compared with that of 15th October. Total number of roots/fed and abnormal root % were insignificantly affected by sowing dates. Sowing sugar beet by using paper pots seedlings of 15 days age produced the highest and significant values of growth traits, total root numbers/fed, as well as root top and sugar yields/fed and gave the lowest value of abnormal root %. The results showed that the application of zinc element alone or in combination with boron element significantly resulted in higher values of root length, root diameter, top yield/fed compared with those recorded by unfertilized or applied with boron only. Application of boron alone or in combination with zinc produced higher root fresh weight/plant, sugar recovery % as well as root and sugar yields/fed compared with those recorded by the unfertilized or applied with zinc alone. | ||
