The Effect of Water Stress on Growth and Production of Peanuts (Arachis Hypogaea L.)

Introduction

Water stress is a critical factor that affects the growth and production of various crops, including peanuts (Arachis hypogaea L.). Peanuts are one of the most widely cultivated legumes in the world, and their production is heavily dependent on the availability of water. In this study, we investigated the effect of water stress on the growth and production of peanuts, with a focus on the amount and interval of water administration.

Background

Peanuts are a drought-tolerant crop, but they still require adequate water supply to optimize their growth and production. Water stress can occur due to various factors, including drought, poor irrigation management, and soil type. The effects of water stress on peanuts can be significant, including reduced growth, lower yields, and decreased seed quality.

Methodology

This study was conducted in the Greenhouse of the USU Faculty of Agriculture, using varieties of elephant peanuts and gray hydromorphic soil media (inseptisol) in polybags. The study lasted for four months, from June to September 2003. We used a random group design (RAK) with two main factors: the amount of water administration (A) and the interval of water giving (T). The amount of water administration had four levels: 100% field capacity, 80% field capacity, 60% field capacity, and 40% field capacity. The interval of water giving had four levels: giving water every 1 day, giving water every 3 days, giving water every 5 days, and giving water every 7 days.

Results

The results of the study show that:

  • Water giving interval significantly affects the amount of ginofor, the upper dry weight of the plant, leaf area, number of pods formed and contains, as well as seed weight. However, water intervals do not significantly affect the number of branches of plants, age of flowering, dry weight of the lower part of the plant, net assimilation rate (Lab), relative growth rate (LPR), and harvest index.
  • The amount of water giving significantly affects the number of ginofor, leaf area, number of pods formed and contains, seed weight, and net assimilation rate (Lab). However, the amount of water administration does not significantly affect the number of branches, age of flowering, the upper and lower dry weight of plants, relative growth rates (LPR), and harvest indexes.
  • Interaction between intervals and the amount of water administration does not significantly affect all measured parameters.

Deeper Analysis

The results showed that water stress had a significant impact on the growth and production of peanuts. Water stress that is too high (longer water interval) can cause a decrease in the number of ginofor, the upper dry weight of the plant, leaf area, number of pods, and seed weight. This is because water stress can interfere with the physiological processes of plants, such as photosynthesis, nutritional translocation, and flower formation and pods.

On the other hand, excessive giving water (100% field capacity) also does not provide optimal results. This is probably caused by lack of oxygen in the soil due to flooding water, thus inhibiting root growth and nutritional absorption.

Conclusion

This study shows that there is an optimum range in providing water for the growth and production of peanuts. Giving excessive water or too little can cause a decrease in yield. Therefore, the regulation of the amount and interval of water administration is important to increase the production of peanut production.

Recommendation

  • Further research needs to be done to determine the optimum range of amount and interval of water administration for other peanut varieties.
  • It is important to consider other factors that can affect the growth and production of peanuts, such as soil types, climate conditions, and plant varieties.
  • The application of an efficient and water-efficient irrigation system needs to be done to minimize water loss and increase the efficiency of water use.

Implications

The findings of this study have significant implications for peanut production and irrigation management. The results suggest that peanut farmers should aim to provide an optimum range of water supply to their crops, rather than relying on excessive or inadequate water administration. This can be achieved through the use of efficient irrigation systems and careful monitoring of soil moisture levels.

Future Research Directions

Further research is needed to determine the optimum range of amount and interval of water administration for other peanut varieties. Additionally, studies should be conducted to investigate the effects of other factors, such as soil types, climate conditions, and plant varieties, on the growth and production of peanuts.

Limitations

This study had several limitations, including the use of a small sample size and the lack of consideration of other factors that may affect peanut growth and production. Future studies should aim to address these limitations and provide a more comprehensive understanding of the effects of water stress on peanuts.

Conclusion

In conclusion, this study provides valuable insights into the effects of water stress on the growth and production of peanuts. The results suggest that there is an optimum range of water supply that is necessary for optimal peanut production. Further research is needed to determine the specific requirements of different peanut varieties and to investigate the effects of other factors on peanut growth and production.
Frequently Asked Questions (FAQs) about the Effect of Water Stress on Growth and Production of Peanuts (Arachis Hypogaea L.)

Q: What is water stress, and how does it affect peanut growth and production?

A: Water stress is a condition where plants do not receive adequate water supply, leading to reduced growth and production. In peanuts, water stress can cause a decrease in the number of ginofor, upper dry weight of the plant, leaf area, number of pods formed and contains, and seed weight.

Q: What are the optimal levels of water administration for peanut growth and production?

A: The optimal levels of water administration for peanut growth and production are between 60% and 80% field capacity. Providing water at this level can help to optimize peanut growth and production.

Q: What are the effects of excessive water administration on peanut growth and production?

A: Excessive water administration can lead to a decrease in peanut growth and production. This is because excessive water can cause flooding, leading to a lack of oxygen in the soil, which can inhibit root growth and nutritional absorption.

Q: What are the effects of inadequate water administration on peanut growth and production?

A: Inadequate water administration can also lead to a decrease in peanut growth and production. This is because peanuts require a certain level of water supply to optimize their growth and production.

Q: How can peanut farmers minimize water loss and increase the efficiency of water use?

A: Peanut farmers can minimize water loss and increase the efficiency of water use by using efficient irrigation systems, such as drip irrigation or sprinkler irrigation. They can also use mulch to reduce soil evaporation and retain soil moisture.

Q: What are the implications of this study for peanut production and irrigation management?

A: The findings of this study have significant implications for peanut production and irrigation management. Peanut farmers should aim to provide an optimum range of water supply to their crops, rather than relying on excessive or inadequate water administration.
