Use of native corn (Zea mays L.) from two edaphoclimatic regions of Veracruz with potential as hydroponic green forage

Resumen

Objective: To evaluate native corn from two different edaphoclimatic regions, with potential as hydroponic
green forage (HGF) without nutrient solution.
Design/Methodology/Approach: A completely randomized experimental design was used with 5 treatments
and 3 repetitions each: T1 hybrid (HR), T2 Almolonga (ALF), T3 Coyutla (CPC), T4 Coyutla (CFJ), and T5
Coyutla (CMJ).
Results: The ALF treatment was superior in the height (28 cm) and root length (14.7 cm) variables. For its
part, CMJ recorded the highest leaf width (2.8 cm) and length (20.5 cm) values. However, ALF had higher yield
(36.80 kg m2), dry matter (4.89 kg m2), protein content (29.88%), crude fiber (39.28%), and mineral content
(4.95% N, 4.95% P, 5.95% K, and 1.97 kg of dry matter).
Study Limitations/Implications: Native corn from two different regions are proposed as an alternative
HGF.
Findings/Conclusions: Native ALF corn with irrigation and without nutrient solution recorded better results
as an alternative HGHGF in the following agronomic variables: yield, protein content, crude fiber, and mineral
content in biomass.
