Abstract
Barangan banana (Musa acuminata L.) is a plant that has the biggest contribution to national fruit production. The increasing demand for the banana requires the availability of seedlings, while conventional cultivation is unable to produce healthy, disease-free seedlings in a short time and large amount. In vitro culture is considered to be able to handle the constraints of the conventional seed supply. The purpose of this study was to determine the effect of foliar fertilizers on in vitro multiplication of barangan bananas. The method used was a single factor of Completely Randomized Design (CRD), the addition of leaf fertilizer consisting of five levels of media treatment, media MS (control), and 0.50 ml L-1 (p1); 0.75 ml L-1 (p2); 1.00 ml L-1 (p3); 1.25 ml L-1 (p4); 1.50 ml L-1 (p5) of leaf fertilizer media repeated five times. The data were analyzed with Analysis Variance then followed by Duncan Multiple Ranged Test of 5%. The results showed MS media still gave the best results compared to other leaf fertilizer media. Meanwhile, the leaf fertilizer media used in this study still gave good results on the initial time of buds appearance (p3 treatment), the number of shoots and the number of leaves in the p5 treatment, as well as the height of the plant in the p4 and p5 treatments. Therefore, the leaf fertilizer can be used to substitute MS media
Highlights
Banana is served as a staple food by millions of people around the world
Barangan banana tastes sweeter; its skin color is yellow with black spots when ripe; the flesh color is reddish, dry and has good smells (Balai Pengkajian Teknologi Pertanian Indonesia, 2009)
This research used the experimental method in Completely Randomized Design (CRD), which consisted of 6 treatments and five replications, so there were 30 experiment samples
Summary
Banana is served as a staple food by millions of people around the world It is rich in carbohydrate sources with a calorific value of 67/100 g of banana flesh. That’s why Barangan banana is one of the banana plants with great potential and opportunity to be developed (Zebua et al 2015) It is one of the specific fruits from North Sumatra which people highly favor because of its advantages over other bananas. Barangan banana is rich in dietary fibre, protein, minerals such as sodium and potassium, fat, and yeast and produces sugar (Shankar et al 2017). It becomes a commercially superior commodity with increasing demand. It is known as red bananas that is widely cultivated in Southeast Asia
