THE EFFECT OF COCONUT JUICE (Cocos nucifera) AS FOLIAR SPRAY IN THE GROWTH AND YIELD OF RADISH (Raphanus sativus)

Radish needs enough nourishment in order to grow and develop and coconut juice as foliar spray is a big help on its growth and development since the nutrients are absorbed through the leaves and not through the soil. The coconut juice is not just a liquid to rehydrate a person but also a source of many nutrients like calcium, manesium, potasium, and also Phytohormones. These are nutrients and hormones that help an organism grow or develop but the best concentration to enhance the growth of plants is yet to be determined. Thus, this study is done in order to determine the effectiveness of the coconut juice in terms of Leaf Area Index, the number of leaves the length of roots, the number of marketable and non-marketable radishes based on the applied concentrations. This study used a Randomized Complete Block Design with four treatments focusing on different concentrations of coconut juice mixed with water. The treatment were 25% coconut juice, 50% coconut juice, 75% coconut juice and 100 % coconut juice. The result shows that Leaf Area Index (LAI), number of leaves, number of marketable and non-martketable plants was all not significant. The only significant data was the length of roots of radish. The length of roots of radish ranges form 15.60 cm T1(25% coconut juice) to 17.63 cm T4 (100% coconut juice). Overall, the most effective concentration of coconut juice which resulted to optimum results is the 100% coconut juice. The higher the amount of coconut juice in the foliar applicationm, the better the effect on the main root of the plant. Thus, it is recommended to use the 100% coconut juice as foliar spray in radish.
