ABSTRACT
Adlay (Coix lacryma-jobi L.) is an additional staple crop in the Philippines to help attain food security. Growth and yield trials have been conducted, however, results vary from season to season. This study was conducted at the Agricultural Experiment Center, Central Mindanao University, University Town, Musuan, Bukidnon, Philippines to evaluate the phenology and field performance of the adlay grown under adverse climatic conditions. The experiment was laid out in RCBD with the six adlay cultivars as treatments (V1-Gulian, V2-Ginampay, V3-Tapol, V4-Pulot, V5-Kiboa, and V6-Dwarf) in four replications and conducted from December 2015 to September 2016. Each cultivar was planted in 16 square meter plot and spaced at a distance of 90cm between rows and 60cm between hills, with two seeds per hill. Of the 14 parameters measured, four significantly differed (plant height at maturity, number of grains per panicle, number of filled grains per panicle, and grain yield per hectare). Under unfavorable conditions, growth duration of adlay extended by two to three months. Findings suggest that all adlay cultivars were drought tolerant, except the Pulot cultivar.
Key words: food security, cultivar, drought, tolerant, parameter.
