The study aimed to increase summer groundnut yield by using foliar nutrition. After three years of research, it was found that applying 75% recommended dose of fertilizer along with water-soluble fertilizers at specific stages significantly increased pod and kernel yield, as well as monetary returns. Treatment T11 showed the best results, followed by treatments T9 and T10, which were also effective in improving yield and profitability. This research suggests that foliar application of fertilizers can enhance summer groundnut production, leading to higher yields and better economic returns for farmers.
