Purpose – The purpose of the research aims to observe the high growth of corn crops with a different cropping pattern.

Design/Methodology/Approach – The research is conducted based on field experiments with Group Randomized Design (hereafter RAK shortened from Cluster Random Design). The treatment of cropping pattern I is that corn crops are planted in one row with the size of plot 9 m × 4 m, and the distance planting of the crops is 70 cm × 40 cm. Cropping pattern II is that corn crops are planted in two rows with the size of plot 9 m × 4 m, and the distance planting is 70 cm × 40 cm. Cropping pattern III is that corn crops are planted in three rows with the size of plot 9 m × 4 m, and the distance among the crops is 70 cm × 40 cm.

Findings – The result of research shows that the highest corn crops are from cropping pattern II.3 at age 15 and 30 after planting time (called HariSetelahTanam or HST). The increase of cropping rows from one row to two rows indicates that intra-specific competition are more dominant. The growth of crops is faster because they need full sunlight at vegetative and generative stages. The need of full sunlight at the growing stage causes the increasing of stem height of crops to enable the crops to receive the sunlight optimally due to the continuity of photosynthesis process. The increasing growth of stem diameter is in accordance with the growth speed of height plant at the same age.

Research Limitations/Implications – This research intends to find out the best growing process of the plant. Further research is needed to study the outcome of final product of the plant.

Practical Implications – This is to see the utilization of the best cropping pattern and optimal land utilization.

Originality/Value – High growth of corn crops and stem diameter (Zea may, S) with a different cropping pattern has not yet been published.
