قياس تأثير مستويات التقليم و إضافة حامض الهيوميك و الرش الورقي بحامض الجبرليك (GA3)‎ في الحاصل و المحتوى المعدني في أعناق الأوراق لكرمات عنب (بيدنيك)‎ Vitis vinifera L.

Abstract EN

The study was conducted at orchard of Agriculture Research Center/Ainkawa / Erbil north of Iraqduring two growing seasons 2013 and 2014 on grape currant (Vitis vinifera L.) Bea – Denk cultivars were trained of Alghemriaat and spur pruning let (8) cane is fixed number and let them (6 , 8 and 10 bud or eye / cane), of add humic acid concentration are (zero , 4.5 and 9 g/ vine) and Gibberellic acid spraying were done (zero , 50 mg / L), effect on Yield (bunch weight and total yield of vine) and Mineral content (N , P , k) in petiole.

Using of randomized complete block design (RCBD) at three block.

The levels of pruning 8 eye / cane caused significant increase inbunch weight, total yield of vine andMineral content (N , P , k) in petiole.

added 9 g humic acid / L led significant increase in bunch weight, total yield of vine andMineral content (N , P , k) in petiole.

also reached the same results when gibbereliic acid spraying.

Interaction between of pruning 8 eye / cane + 9 g humic acid / L + 50 mg GA3 / L gave the best results for thebunch weight, total yield of vine andMineral content (N , P , k) in petiole the for both seasons.
