Abstract
A study was carried out in apricot orchard in Garderashe field– Salahhadeen University – Arbil. Two Drip irrigation systems were used. Normal tubing & Modified emitters locations with two emitters are short & elongated during three months: March, April & May and effects of this factors on; Mechanization parameters and Plants parameters. The statistical results illustrated the effect of drip irrigation system on all parameters which included; superlative of the modified system significantly on all parameters than the normal system. The effect of interaction between drip irrigation system with emitters and with months on all parameters are The treatment of the modified system with the short emitters in April month is recorded highest ratio of weeds control (85. %), highest wetted Area (0.640 m2), highest height of the trees (19 cm), highest diameter of the tree (0.877 cm), highest height of the main branch of the trees (23.333 cm). highest number of flower bud in one tree (889), highest number of fruit tie in one tree (830), highest quantity of fruit yield (11 kg). The interaction of the modified system with the short emitters in April month is recorded highest efficiency (91%) and lowest manufacturers variation (0.03). The modified system generally is superlative on the normal system by recorded lowest (qc) values from the normal system. From this modification an increased stationary force of roots in the soil and be achieved by increasing wetted area and easily cultivation for weed protect that will effect on trees breeding, as a result production increased.
