Ảnh hưởng của xử lý KCl trước khi gieo hạt đến năng suất và phẩm chất của hai giống lạc L12 và L18

The study was conducted to evaluate the effect of 0.05% KCl on yield

and quality of two peanut varieties L12 and L18 grown in Thanh Hoa

province. The experiment was arranged in a completely randomized

design with two factors (varieties and chemicals). After careful selection,

L12 and L18 seeds were divided into two parts. Part 1 was treated with

distilled water as control and part 2 was treated with 0.05% KCl. The

results showed that pre-sowing seed treatment with 0.05% KCl increased

the yield components and yield of both L12 and L18 when compared

to the control, in which the yield of L18 in both treatments reached

37.37 quintals/ha and 39.54 quintals/ha and was higher than that of the

L12 variety at 35.77 quintals/ha and 36.40 quintals/ha. 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. Briefly, the results of this study indicated

that pre-sowing seed with KCl increased the yield and quality of peanuts.
