الرش بالخارصين و الحامض الأميني الكلايسين Glycine في نمو و حاصل نبات الباقلاء

Abstract EN

A field experiment was conducted during winter season of 2011-2012 at Shatelarab district, Basrah governorate to study the effect of foliar application zinc and amino acid glycine on growth and yield of green faba beanplant ViciafabaL.

cv.

"Luz de otono".

The experiment included 12 treatments resulted from the interaction among three zinc conc.

(0,25,50 mg.l-1) as ZnSO4.7H2O ( 22.7%Zn) and four amino acid glycine conc.

(0,50,100,200) mg.l-1 applied at three times at 15 days intervals starting from 45 days after sowing.

Randomized Complete Block Design (RCBD) was used in (3×4) a factorial experiment.

Results showed that spraying with zinc significantly increased the characteristics of vegetative growth, flowering, yield and its component and seed quality characteristics as compared with control treatment.

Treatment with glycine significantly increased the all above characteristics as compared with control treatment.

The interaction of zinc at 50 mg.l-1with glycine 200 mg.l-1 gave the highest values of productivity of green pod (12.442 ton.donum-1) (Donum=0.25 ha) and the productivity of fresh seeds (7.094 ton.

donum-1) whereas, control treatment gave lowest values of the productivity of green pod (4.351 ton.donum-1) and the productivity of fresh seeds (2.358 ton .donum-1).
