| Abstract | ||
| This survey was performed in (2005), on Royal apricot trees grafted on apricot seedling root stocks planted in (1999) at Grdarash fruit orchard with cilty clay loam follows Agricultural college, university of Saladden / Arbil. Fifty four apricot trees were selected and they divided into three blocks , each block containing (18) uniform trees , and the includes of each block were divided into three parts and each part included (6) trees , each part was sprayed at three different times then this (6) trees were divided into two parts , each part sprayed different material from the other , they were Urea powder solution & Agrosoil-plex in three different concentrations for each of them , which was (0, 1000 , 2000 mgm / liter) urea solution , (0, 1000 , 2000 micro ml / liter) Agrosoil - plex , and the period between each spray was one month , the first time was in (26-1-2005) for increasing yield , and improving chemical & physical characteristics of Apricot fruit (Royal). R.C.B.D designing were used, analysis of variance and L.S.D test were applied on all research data. The important results of this study can be summarized as follows: 1- The treatment by the third concentration (2000 micro ml / liter) from Agrosoil-plex and in the first date of spraying (26 – 1 - 2005) caused significant increasing fruiting. 5- The spraying by (2000 mgm / liter) urea in the second date of spraying (26 – 2 - 2005) caused the largest size of fruits. 6- The treatment by the second concentration (1000 mgm / liter) from urea and in the second date of spraying (26 – 2 - 2005) caused the largest weight of fruits. 9- Significant increasing was obtained in T.S.S & sugre content (total & reduced) ratio by spraying (1000 microml / liter) Agrosoil-plex in the second date of spraying (26 – 2 - 2005). | ||
