Effect of spraying nano potassium fertilizer and the growth regulator Cytokinen on yield of Faba Bean Vicia Faba L.

A field experiment was conducted in Al-Hassi District / Fallujah / Anbar Governorate in the season 2020-2021. study the impact of nano potassium (Nano-K) and Cytokinen (CK) on yield of the local type of fava beans. The split system was used as per a fully randomized block design, R.C.B.D, and three replicates. The main blocks included four concentrations of CK; 0, 50, 100 and 150 mg. L⁻¹, while the secondary blocks contained four concentrations of Nano-k; 0, 1, 2, and 3 g L⁻¹. The results of the experiment are as follows: NK concentrations influenced all studied properties. Where the concentration of 2 g/L influenced most of the studied properties, such as the number of pods per plant 25.60 pod. Plant⁻¹, length of pods 70.15 cm, the fertility rate per pod 96.88%, the number of seeds per plant 4.98 seed. Pod⁻¹, weight of 100 corn is 138.56 gm, and the total yield is 12.07 mg.hec⁻¹. CK concentration 100 mg. L⁻¹ significantly influenced most of the studied traits. The number of pods per plant is 24.84 pod. Plant⁻¹, the fertility rate per pod is 96.93%, the weight per 100 seeds is 130.84 gm and the total yield is 12.17 mg.hec⁻¹. The interaction between NK and CK influenced most of the studied traits as 2 gm reacted. L⁻¹ and 100 mg. L⁻¹ (NK x CK) had the highest mean number of pods per plant 36.67 pod. Plant⁻¹, and pods 16.95 cm long, while the 1 g combination achieved L⁻¹ and 100 mg pods. L⁻¹ (NK x CK) has the highest mean fecundity in pods of 97.78% and seed yield of 14.61 mg.hec⁻¹. The combination of 2 g L⁻¹ and 50 mg yielded the highest mean weight of 100 seeds at 148 gm.
