Effect of nano npk and mineral fertilizer on yield and components of three barley cultivars

الملخص EN

Afield experiment was carried out in Al-Rumaitha district during agricultural season at 2019-2020, In order to find out the response of three varieties of barley(Buraq, Abaa 99, Abaa 265) to foliar application with nanoparticle fertilizer NPK based on recommendation of mineral fertilizer for ground fertilization ( T1 =control treatment, T2 =0% mineral recommendation + 1.5g NPK 20: 20: 20 nan fertilization, T3=0% mineral recommendation + 3g Nano fertilizer, T4=50% mineral recommendation + 0g Nano fertilizer, T5 =50% mineral recommendation + 1.5g Nano fertilizer recommendation, T6=50% mineral recommendation + 3g Nano fertilizer, T7=100% mineral recommendation, T8=100% mineral recommendation + 1.5g Nano fertilizer and T9=100% mineral recommendation + 3g Nano fertilizer).

The experiment was carried out in Randomized Completely Block Design (R.

test at the level 0.05.

The results summarized as follows: The cultivars Abaa99 and Abaa265 were significantly superior in most of the studied traits, except weight 1000 grains.

T8 treatment was affected significantly on number of spikes and the total yield, T5 was superior in harvest index.

The interaction between Abaa265 and T8 was significantly superior on grain yield.
