Effect of spraying some nano-fertilizers and their combinations on the growth and yield of fenugreek (Trigonella foenum-graecum L.)

摘要: The experiment was conducted in one of the special fields for the winter agricultural season 2020/2021 in Al-Qadisiyah province/Sumer-Al-Barakat sub-district, which is 17 km from the district, at 32.14 degrees north latitude and 44.99 degrees east longitude. To know the effect of spraying some nano-fertilizers and their combinations on the growth and yield of the fenugreek, the experiment was carried out according to a randomized complete block design with three replications. The experiment included 10 treatments (T1), the control treatment, spraying distilled water only,(T2) a balanced nano-NPK spraying at a concentration of 2 g L-1,(T3) adding NPK mineral fertilizer 200 kg ha-1,(T4) Spraying nano microelements 2 g L-1+ NPK mineral fertilizer,(T5) Spraying nano seaweed extract 2ml. L-1+ adding NPK mineral fertilizer,(T6) spraying nano NPK at a concentration of 2 gL-1+ mineral NPK,(T7) Spraying nano micro …
