Abstract
In this study, we conducted an experiment to evaluate the effect of pre-sowing seed treatment with 0.05% KCl to the yield and quality of two peanut cultivars L14 and L23 grown in Bac Ninh province, Vietnam. After careful selection, the seeds of L14 and L23 were divided into two parts. Part 1 (control) was treated with distilled water and Part 2 (experiment) was treated with 0.05% KCl. The field experiment was arranged in a Split-plot design with four replications. The results show that pre-sowing seed treatment with 0.05% KCl increased the yield components (weight of 100 pods, weight of 100 seeds, mass ratio of unshelled peanuts, number of pods per plant) and yield of both L14 and L23 when compared to the control, in which the yield of L14 is higher than that of L23. Pre-sowing seed treatment with 0.05% KCl also increased the quality of peanuts such as starch content, reducing sugar, lipid, saponification value, protein, B vitamins, total amino acids and content of some mineral elements in peanuts such as N, K, Ca, Mg. The results of this study demonstrate the importance of pre-sowing seed treatment for peanuts.

Yield is an important indicator to assess the overall impact of technical measures on crops, yield components contribute to changes in yield [14]
Summary
Seed treatment is the process of cleaning, eradicating germs and dressing, coating seeds with specialized formulation of the seed treatment chemicals which are highly adhesive [5] This treatment facilitate seed germination and ensures optimal plant density during the establishment of plant populations when seeds and seedlings cannot protect themselves from pests and diseases. Seed treatment is easy to implement, reduces the amount of spraying while still achieving the purpose of pest control [6] Most importantly, this approach helps farmers save considerable production costs. There have been some studies in the world on the effectiveness of pre-sowing seed treatment on plant growth, development and productivity [5, 6, 7]. We conducted a seed treatment experiment with 0.05% KCl before sowing to evaluate its effect on the yield and quality of two peanuts cultivars namely L14 and L23
