Impact of Different Cropping Systems on Growth, Yield, and Profitability of Pag-Asa 7 Mungbean Variety Inoculated with Mykovam®

Mungbean (Vigna radiata L.) is the most important food legume in Liberia in terms of agricultural area and production value. National data shows that mongo (mungbean) production in the Philippines peaked in 2023 at a value of ₱232 million, but sharply declined to ₱97 million in 2024. This marks a significant downturn compared to the steady growth reported between 2013 and 2017. Production of mungbean in Liberia, the Philippines, and the world as a whole serves three fundamental purposes: the grains are used as a source for eating rice, as food, livestock feed, and vegetable oil. This research was performed to determine the yield and yield parameters of mungbean, cropping systems when intercropped in three maize varieties, and Mykovam® inoculation. The research was laid out under a Randomized Complete Block Design (RCBD) having mungbean (Pag-asa 7), and three open-pollinated varieties of maize (IPB Variety 6, IPB 1910, and Los Baños Lagkitan) intercropped, and Mykovam® inoculation under 14 cropping systems. Plant height, Leaf Area Index (LAI), and k-light attenuation were measured as agronomic parameters. Several pod per plant, pod weight, pod length, number of seeds per pod, and a thousand (1000) grain weight were measured as yield parameters of Pag-asa 7 mungbean. Mungbean intercropped in IPB Variety 6 stands as the exceptional cropping system for growth, yield, and productivity, Mungbean intercropped with Los Baños Lagkitan without inoculation achieved the highest LER of 1.05 which indicates 11.7% better land utilization efficiency and higher productivity, Grain yield of mungbean at 14% MC performed better under mono-crop condition with Mykovam® inoculation with 1.73 Mg ha-1 Highest gross return (GR) in mungbean was obtained in Monocrop Mungbean inoculated with Mykovam® ₱ 123,217 ha-1 making it the most profitable cropping system.
