This study aims to examine the best responses in growth and yield of shallot cultivars to the inoculation of Trichoderma asperellum cultivated in coastal sand soils. The research was carried out in the coastal sand field in Samas, Bantul, Yogyakarta, from January to March 2017. The experiment was a factorial experiment, consisting two factors arranged in a completely randomized block design (CRBD) with three replications. The two factors are various shallot cultivars, consisting of 20 cultivars, and the inoculation of Trichoderma asperellum isolates, consisting of two levels namely without and with inoculation. Result showed an interaction between Trichoderma asperellum and onion cultivars on total chlorophyll content and total dry weight per plant. Various shallot cultivars show the greenness of the leaves, plant height, number of leaves per plant, and the variety of fresh bulb weight per plant. Inoculation of Trichoderma asperellum produced better leaf greenness, stomata opening width, number of roots, plant height, number of plant leaves, fresh bulb weight per plant than without inoculation. Cultivar that shows best growth and yield was Biru Lancor. |
