The investigations have been carried out in the period 2008-2013 using the apple variety Golden Delicious grafted on the M26 rootstock. The planting distance of trees was of 4x2 m (1250 trees/ha). Ochard soil is maintained as worked fallow. Nitrogen was used as Urea 46% N active substance (NH2)2CO in the concentrations of 0.4%, 0.5% and 0.6%, using about 1000 l of solution per hectare, when 75% of the flowers are open and until the flowers lose their first petals. The trees sprinkled with water served as a control variant. Spraying was done in the morning with the portable sprayer, when the wind speed is minimal and the temperature is lower. The use of Urea 46% N, in the blooming phenophase, has a double effect, both of the flower thinning and the growth of the fruit. The highest values of fruit harvest were recorded by the trees that have been treated with foliar fertilization if the solution was applied in concentrations of 0.5% and 0.6% was applied. |

Distanța de plantare a pomilor – 4x2 m (1250 pomi/ha). Solul din plantație se menține ca ogor lucrat. Azotul s-a utilizat sub formă de soluţie de uree de 46% N, substanța activă (NH2)2CO, în concentrație de 0,4%, 0,5% și 0,6%, consumându-se câte 1000 l soluție la hectar. Soluţia a fost aplicată prin stropire, la etapa când 75% din flori sunt deschise până la scuturarea petalelor primelor flori. Ca variantă martor au servit pomii stropiți cu apă. Stropirea s-a efectuat dimineața, când vântul are viteză minimă și temperatura este mai scăzută, cu stropitoarea portabilă. Utilizarea soluţiei de uree 46% în fenofaza înfloririi are efect dublu, atât de rărire a florilor, cât și de creștere a fructelor. Recolta de fructe a înregistrat cele mai mari valori la pomii cu fertilizare foliară, la care soluţia s-a aplicat în concentraţii de 0,5% şi 0,6%.</p></cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-4338</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-12751</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-12747</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-55475</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> </cfPers_ResPubl> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-4338</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-4338-2</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> <cfFamilyNames>Балан</cfFamilyNames> <cfFirstNames>Валериан</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-12751</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-12751-2</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> <cfFamilyNames>Vămăşescu</cfFamilyNames> <cfFirstNames>Sergiu</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-12747</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-12747-2</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> <cfFamilyNames>Пештяну</cfFamilyNames> <cfFirstNames>Анание</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-55475</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-55475-2</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2019-10-19T24:00:00</cfStartDate> <cfFamilyNames>Balan</cfFamilyNames> <cfFirstNames>Petru</cfFirstNames> </cfPersName_Pers> </cfPers> </CERIF>
