Abstract
Problem: Maize is one of important food for Indonesian people. The problem faced by Indonesian government is the maize is not sufficient to suffice the this country demand.
Aims: The research aimed to study the interaction between several hybrid maize varieties and plant spacing to growth and yield of hybrid maize
Study Design: Factorial design in randomized block design.
Place and Duration of Study: The research was conducted in Siguntur, Sitiung 1, Dharmasraya, West Sumatra and Indonesia from April to July 2018.
Methodology: Factorial design in randomized block design with 2 factors was used in the assay. The first factor was hybrid maize varieties (Pioneer P35 and Pertiwi 3) and the second factor was planting space (75 cm x 20 cm, 75 cm x 30 cm and 75 cm x 40 cm). The data was analyzed by ANOVA.
Results: The result showed that no interaction between planting spacing and varieties to growth and yield of maize. The best hybrid maize variety for growth and yield was Pioneer 35. The best planting space for growth and yield was 75 cm x 20 cm.
Conclusion: The interaction between plant spacing and hybrid maize varieties did not affect the growth and yield of hybrid maize.
Recommendation: The further research are recommended to study the effect of plant spacing and hybrid maize to growth and yield of maize.
Keywords: Hybrid maize, plant spacing, varieties, Zea mays L.
