ABSTRACT
Production of green maize in Liberia, Philippines, and other part of the world serves as a whole three fundamental purposes where cobs are consumed directly as food, livestock feed and vegetable oil. This research was performed to determine the yield and yield parameters of maize varieties and mungbean, cropping systems, and inoculation. The research was laid-out under a Randomized Complete Block Design (RCBD) having three open pollinated varieties of maize (IPB Variety 6, IPB 1910 and Los Baños Lagkitan) intercropped with mungbean (Pag-asa 7), and inoculation (Mykovam ®) under 14 cropping systems. Plant height, Leaf Area Index (LAI), and Light attenuation (k) were measured as agronomic parameters. Weight of unhusked ear-1, marketable ear, ear-1 length, number of kernels ear-1, and a hundred (100) kernels weight were measured as yield parameters of maize. IPB Variety 6 stands as the exceptional variety for growth, yield and productivity, with the highest yield among the three maize varieties. There was better grain quality in the intercropped with inoculation than monocropped and un-inoculated intercropped. Los Baños Lagkitan intercropped mungbean and Mykovam inoculation achieved the highest crude protein among the three varieties in the research.

INTRODUCTION

Growing two or more crops in mixed stands has been, and continues to be a tradition in subsistence farming in Liberia and the Philippines Dingkuhn,el at(2006). Farmer’s experience over the years and the results of numerous studies on multiple cropping have confirmed that there exists a potential for obtaining yield advantage by growing more than one crop simultaneously on a given piece of land. Until recently, it has been suggested that growing crops in association, as in intercropping, allows efficient utilization of the environmental resources (Deininger & Byerlee, 2011). However, the underlying principles leading to efficient resource use by intercrops has remained obscure (LaCanne, 2017).
