Potassium, Calcium and Sodium Distribution in Different Part of Common Vegetable Plants Grown under Field Condition

Abstract

A field experiment was conducted to investigate the distribution of Potassium, Sodium, Calcium in different parts of commonly used vegetables. Complete Randomize Design (CRD) was followed for the experiment. Seeds of nine vegetable plants were collected and cultivated. After 45 days, vegetables were harvested and nutrient concentration in different parts of nine vegetables (leaf, petiole and stem) was measured. The distribution order of potassium, sodium, calcium concentration among leaves, petioles and stems was found as petiole>stem>leaf, petiole>leaf>stem, petiole>leaf>stem, respectively. But individually, high concentration of K, Ca, Na was found in Corchorus capsularis, Amaranthus lividus (Green) and Spinacia oleracia, respectively and low concentration was found in Lagenaria siceraria for all nutrients. The K, Ca, Na concentration among the plants and within different parts of the each vegetable was significant (p<0.05). The present research work revealed that Corchorus capsularis, Amaranthus lividus (Green), Spinacia oleracia was highly nutritious for measured nutrients but Lagenaria siceraria contained low concentration of all measured nutrient. But for all the vegetables, petioles are highly nutritious compared to other parts of vegetables.
