Field Performance and Economic Analysis of Different Adlai (Coixlacryma-Jobi L.) Cultivars Grown Under Lowland Conditions in Cebu City, Philippines

Abstract

Adlai (Coixlacryma – jobi L.) had a higher potential alternative crop for rice and corn, but information about this crop is still limited. This study was conducted to; a) evaluate the agronomic component, yield, and yield characteristics; and b) determine the economic analysis of different Adlai cultivars under lowland conditions of Carcar City, Cebu. The area (360 m2) was laid out in Randomized Complete Block Design (RCBD). Three Adlai cultivars were designated as treatments replicated thrice. All treatments were applied uniformly with inorganic fertilizer at the rate of 120-60-60 kg/ha N, P2O5, and K2O using complete fertilizer (14-14-14) and urea (46-0-0). Among cultivars, Tapol and Gulian markedly headed and matured earlier than Ginampay. Tapol cultivar grew taller and produced longer panicles with extended and broader leaves. Meanwhile, Gulian had a higher number of panicles than Tapol and Ginampay. In terms of yield, Tapol cultivar produced a higher grain yield comparable to Gulian and Ginampay. However, only the Tapol cultivar generated the highest gross margin and percent return on investment of PHP 59, 269.79 and 3.51 which indicated as high adaptability of Tapol cultivar under lowland conditions in Carcar City, Cebu.
