Abstract
Abstract The experiment was conducted in an unheated plastic house at Al-Abassia/Al-Najaf Governorate during autumn seasons of 2016. The objective of this work to study the effect of foliar and soil applied fertilizers on growth and yield of cucumber ( Cucumis sativus L. cv. Siyff). Results indicated that: The foliar spray with 10ml L −1 of the liquid fertilizer was superior in all traits and studied gave the highest value in leaf area index (20.8) plant dry weight (40.9) g, IAA (185.85) mg kg −1 , GA3 (187.2) mg kg −1 , CK (178.1) mg kg −1 . The treatment (F1) of mineral fertilizer was superior significantly in leaf area index (23.5) and plant dry weight (42.8) g. The treatment (F3) was superior in IAA (196.39) mg.kg −1 and GA3 (199.8) mg.kg −1 , CK (196.1) mg kg −1 . The results showed that the interaction treatment spraying foliar fertilizer at a concentration 10ml.L −1 and 50% of mineral fertilizer was superior significantly in IAA (211.83) mg.kg −1 , GA3 (221.6) kg −1 , CK (214.9) mg. kg −1 .
