Abstract

Shallot seeds have a low germination rate; formulation modification is expected to increase germination and yield. This study aims to analyze the effect of seed formulation and media volume on shallot growth and yield. The research method used a factorial design (5 x 3) arranged in a completely randomized block design (RAKL). The first factor was media formulation (1:0:0, 1:1:1, 2:1:1, 1:2:1, 1:1:2). The second factor was media volume (25 cc, 40 cc, 50 cc). Data were analyzed using analysis of variance and further LSD and DMRT tests. A balanced medium in a limited space allows roots to thrive because nutrients and water are available. increasing media volume is useful in unbalanced media formulations. This is because roots are encouraged to grow long, exploring for additional water and nutrients. M3 (2:1:1) had the highest seedling characteristics but the lowest seedling germination percentage, while M5 (1:1:2) had the shortest seedling characteristics but a high seedling germination percentage and bulb diameter. A seedling media volume of 55 cc increased almost all shallot growth and yield parameters. Nursery parameters had a low correlation with plant growth and yield parameters, so the formulation treatment and media volume in the nursery did not directly affect plant growth and yield.

Abstract

Research on Trichoderma sp. isolates derived from the roots of the wild orchid Paphiopedilum javanicum for application in commercial orchid acclimatization is still limited. The study aimed to determine the optimal dose of Trichoderma sp. isolates to grow hybrid Dendrobium discolor >< lasianthera seedlings at the acclimatization stage. The study was conducted using a Complete Randomized Block Design (CRBD) with non-factorial experiments and repeated 4 times as blocks. Treatments in the form of Trichoderma sp. doses were 0 g, 2 g, 2.5 g, 3 g, and 3.5 g. Trichoderma sp. doses significantly affected the increase in plant height, the amount of chlorophyll a, and root infection. A dose of 2.46 g was the optimal dose that gave a Trichoderma infection rate in the roots of 100%. A dose of 2.5 g gave the best results in increasing plant height (0.625 cm). A dose of 3.5 g gave the best results in chlorophyll a (4.55 mg/l). Trichoderma has the potential to be propagated into a biofertilizer product to support the growth of commercial orchids during acclimatization.
