Early growth response of three shallot varieties to different bulb sizes
Abstract
The early growth of shallot plants is strongly influenced by the variety and size of the seed bulbs used. This study aimed to evaluate the early growth responses of three shallot varieties to different seed bulb sizes. The study was conducted at the Horticultural Experimental Field, Lampung State Polytechnic, using a factorial Randomized Complete Block Design (RCBD). The first factor was shallot variety, consisting of Bima Brebes, Biru Lancor, and Batu Ijo, while the second factor was seed bulb size, classified as small, medium, and large. Each treatment combination was replicated three times, resulting in 27 experimental units. The results showed that Biru Lancor produced the tallest plants (29.86 cm), whereas Batu Ijo had the largest leaf diameter (0.61 cm). Medium and large seed bulbs produced plant heights of 28.98 and 29.06 cm, respectively, a leaf diameter of 0.66 cm, and a sprouting percentage of 100%. The interaction between variety and seed bulb size significantly affected leaf diameter. Medium-sized seed bulbs have the potential to serve as an alternative to large seed bulbs because they produced comparable early growth in several measured traits.
