Abstract


The study evaluated the adaptation capacity of the five varieties of adlai (Coix lacryma-jobi L.) grown in marginal land with adverse environmental conditions through the assessment of crop morphological structures. Based on evaluations of the agronomic traits in two definitive growing stages of the plant, Tapol and Kiboa had developed better vegetative and reproductive structures. Tapol was the topmost high yielding variety followed by Kiboa, Gulian, Ginampay and unknown variety with approximately 3.07 ton/ha, 2.31 tons/ha, 1.85 ton/ha, 1.65 ton/ha and 0.98 ton/ha respectively. Tapol variety has highest number of grains produced per stem with 322 grains and then Kiboa with 205 grains. Kiboa and Tapol were the tallest varieties reaching to a total plant height of 159.6 cm and 152.5 cm respectively. They also have the longest and widest leaves. Kiboa has leaf with 76.5cm long and width of 4.5cm while Tapol has leaf of 73.2cm long and width of 4.4cm. All the varieties are pests and diseases resistance wherein the degree of infestation and infection are below Economic Threshold Level (ETL). Generally, based on the overall performance of the five varieties of adlai, Tapol and Kiboa are the best adaptive to the local environmental condition of the area.
