Measuring the Needs of Oil Palm Water: Evapotranspiration and Plant Coefficient

Palm oil is known as a thirsty crop that requires a significant amount of water to grow optimally. Understanding the needs of oil palm water is crucial, especially in the initial phase of growth in the nursery. Research led by Sumono and Ainun Rohanah examined the value of evapotranspiration and plant coefficient in palm oil seeds varieties (Elaeis guinensis Jack.) at the age of 4 months.

What is Evapotranspiration?

Evapotranspiration is the process of loss of water from the surface of the ground and plants through evaporation and transpiration. The evapotranspiration value of plants can be calculated based on the potential value of evaporation and coefficient of plants for each growth phase. This process is essential in determining the water needs of oil palm plants, as it directly affects their growth and survival.

The Importance of Evapotranspiration in Oil Palm Plants

Evapotranspiration is a critical factor in understanding the water needs of oil palm plants. The value of evapotranspiration varies depending on the growth phase, environmental conditions, and type of plant. In the case of oil palm plants, the evapotranspiration value is influenced by the potential value of evaporation and the plant coefficient.

Plant Coefficient: A Key Factor in Determining Water Needs

Plant coefficient is a factor that shows the ratio of plant water needs to the potential for evaporation. Plant coefficient values vary depending on the type of plant, growth phase, and environmental conditions. The higher palm oil coefficient shows a higher water requirement. Understanding the plant coefficient is essential in determining the optimal water needs of oil palm plants.

The Importance of Managing Water in the Nursery

Water regulation in the nursery is very important for the growth and survival of oil palm seedlings. Lack of water can cause stress in plants, interfere with growth, and increase the risk of death. Conversely, excess water is also dangerous and can cause root decay. Therefore, it is essential to manage water effectively in the nursery to ensure the healthy growth of oil palm seedlings.

Providing Optimal Water Needs

Based on research data, here are some things that need to be considered in managing water in oil palm nursery:

Irrigation

Perform regular irrigation to meet the needs of oil palm seeds, taking into account the value of evapotranspiration and plant coefficient.

Drainage

Make sure the nursery land has a good drainage system to avoid standing water that can interfere with root growth.

Monitoring

Monitor the condition of the plant regularly to detect symptoms of lack or excess water.

Conclusion

By paying attention to water needs and applying proper water management practices, oil palm seeds can grow healthy and strong, ready to be planted in oil palm plantations. This information is important to increase the production and sustainability of oil palm plantations.

The Results of the Study

The results of this study provide an important picture of the needs of oil palm water in the initial phase of growth. This information can be used to determine optimal water needs in the nursery, so that oil palm seeds can grow healthy and strong.

Evapotranspiration Value

The evapotranspiration value of 5 months old palm oil seeds (initial phase) reaches 0.9 mm/day, and increases to 0.98 mm/day at the age of 6 months (final phase).

Potential Evaporation

The potential evaporation in the initial phase of the research was recorded at 1.98 mm/day, and slightly decreased to 1.93 mm/day in the final phase.

Plant Coefficient

The oil palm plant coefficient at the beginning of the study was 0.47, and increased to 0.5 in the final phase.

Implications of the Study

The results of this study have significant implications for the management of oil palm plantations. By understanding the needs of oil palm water, farmers can optimize water use and reduce waste. This can lead to increased productivity and sustainability of oil palm plantations.

Recommendations

Based on the results of this study, the following recommendations are made:

Regular irrigation should be performed to meet the needs of oil palm seeds.
A good drainage system should be installed to avoid standing water that can interfere with root growth.
The condition of the plant should be monitored regularly to detect symptoms of lack or excess water.

By following these recommendations, oil palm seeds can grow healthy and strong, ready to be planted in oil palm plantations. This information is important to increase the production and sustainability of oil palm plantations.

Q&A: Understanding the Needs of Oil Palm Water

Q: What is evapotranspiration, and why is it important in oil palm plants?
