THE EFFECTS OF EGGSHELL POWDER AND POTASSIUM ON GROWTH, YIELD AND ECONOMIC EFFICIENCY OF PEANUT L27 VARIETY IN SPRING CROP IN THANH HOA PROVINCE

Abstract

The experiment was conducted to evaluate the effect of eggshell powder and potassium rates on growth and yield of L27 groundnut variety in spring season in Thanh Hoa province. The two factor experiment was laid out in a split-plot design with three replications. The main factor consisted of three rates of eggshell powder (0, 200, 300, 400 kg/ha). The sub-factor consisted of three rates potassium (80, 100, 120 kg/ha). The results showed that, higher values of growth and yield parameters of L27 groundnut variety were observed under fertilized eggshell powder condition. Increasing the amount of potassium fertilizer increasing growth parameters and yield components of peanut variety L27. Briefly, the results indicated that the rate of 300 kg eggshell powder/ha with 100 kg/ha kali was suitable for L27 groundnut variety to grow, develop and produce the highest yield and economic efficiency in the spring season in Thanh Hoa province.
