Abstract
The research was conducted in the lath house of Agriculture College in Al-Qasim Green University under spraying irrigation system from 11-1-2014 to 6-1-2015 to study foliar application date of PRO-SOL fertilizer and some plant growth promoters at Naval Orange saplings growth at age one year and a half budded on Sour Orange root stocks and planting in plastic pots (diameter 23.5 cm). The saplings were bring from Citrus Certification Researches Center in Karbala Government and the research was done in Factorial experiment (2*7) within RCBD in four replications. First factor represented two foliar application date of PRO-SOL fertilizer (1 g/L) every two weeks during Winter –Spring season(2014-2015) and Spring season dates (2015). Second factor was foliar application of Plant growth promoters in mid-march with IBA 40,80 mg/L ; KT-30(cppu) 15,30 mg/L ; IBA+KT-30 (cppu) 40,15 mg/L consecutively and IBA+KT-30(cppu) 80,30 mg/L consecutively . The results showed surpass of first fertilizing date in Branches number , leaves number and chlorophyll leaves content (SPAD) while no significant effect showed on Plant height , Budding stem diameter and leaf area. For foliar application of Plant Growth Promoters the results showed surpass of KT-30 (30 mg/L) in branches number and IBA+KT-30 (40,15 mg/L consecutively) in leaves number and IBA (40 mg/L) in leaf area while there was no significant increase in plants Height , Budding stem diameter and chlorophyll leaves content .
