Abstract
The germination phase of sugar cane is a critical period that determines productivity. This phase lasts until the sugar cane is three months old, and in this phase, sugarcane requires an adequate supply of water to support the formation of shoots. Poor soil conditions and high rainfall can cause the failure of bud formation. This study aims to determine the relationship between rainfall and soil permeability on the successful construction of sugarcane shoots. We divided the 1 ha research area into nine points (A, B, C, D, E, F, G, H, I) to observe plant growth and soil permeability. The growth factors measured included the number of stems, diameter, and plant height, measured zigzag. Intact soil samples at a depth of 0-15 cm were then analyzed in the laboratory using Darcy^s law to determine the value of soil permeability. The results showed variations in sugarcane growth in the nine research plots. The average number of sugarcane stalks is eight stalks/meter with a height of 159 cm and a diameter of 3 cm. This result is caused by the low soil permeability value of 0.13-0.5 cm/hour, which cannot compensate for the average rainfall in the budding phase, thereby suppressing plant growth by up to 50% of the average productivity that should be.
