Introduction

Rice is one of the most widely consumed staple foods globally, with over 3.5 billion people relying on it as their primary source of nutrition. The growth and production of rice are influenced by various factors, including water management and the provision of fertilizers. In this study, we aim to explore the growth response and results of the treatment of water management and the provision of buffalo manure on various rice varieties. The study focuses on four rice varieties, namely Inpari 1, Inpari 13, Siramos, and Siboru Tambun, and examines the effects of different water management and fertilizer treatments on their growth and production.

Methodology

The study was conducted in a greenhouse setting, where rice was planted in pots. The treatment of water management was divided into two phases, namely intermittent irrigation and inundation. Intermittent irrigation involves watering the plants at regular intervals, while inundation involves flooding the plants with water. The provision of buffalo manure was divided into three types, namely without treatment, C/N 19.80: 1, and C/N 10.15: 1. The C/N ratio refers to the ratio of carbon to nitrogen in the manure, with a higher ratio indicating a higher concentration of nitrogen.

Results

The results of the study showed that the treatment of water management had a significant positive effect on plant growth, which was seen from the height of the plant, the number of tillers, and the number of panicles produced. Intermittent irrigation was expressed as the most effective irrigation method, with the highest plant height, number of tillers, and number of panicles produced. On the other hand, the provision of buffalo manure also contributed to the number of tillers per clump, especially in observation 40 days after planting (HST) and the number of panicles per clump at 60 HST and 100 HST, which showed a significant positive effect.

Effect of Water Management on Plant Growth

The study found that the treatment of water management had a significant positive effect on plant growth. Intermittent irrigation was the most effective irrigation method, with the highest plant height, number of tillers, and number of panicles produced. This is likely due to the fact that intermittent irrigation allows the plants to receive a consistent supply of water, while also allowing the soil to dry out slightly between waterings. This helps to prevent waterlogged soil, which can lead to root rot and other problems.

Effect of Buffalo Manure on Plant Growth

The study also found that the provision of buffalo manure had a significant positive effect on plant growth. The C/N ratio of the manure was found to be an important factor in determining the effectiveness of the treatment. The C/N ratio of 10.15: 1 was found to be the most effective, with the highest number of tillers produced. This is likely due to the fact that a higher C/N ratio indicates a higher concentration of nitrogen, which is an essential nutrient for plant growth.

Variety-Specific Responses

The study found that the different rice varieties responded differently to the treatment of water management and the provision of buffalo manure. Inpari 1, Siramos, and Siboru Tambun showed the highest plant height when using the irrigation method, while Inpari 13 showed optimal growth in continuous inundation. All varieties showed the best results in terms of the number of tillers per clump in the treatment C/N 10.15: 1.

Grain Yield

The study also found that the interaction between water management and buffalo manure had a significant effect on grain yield. Inpari 1, Siramos, and Siboru Tambun showed optimal results in the interaction between continuous inundation and buffalo manure C/N 10.15: 1, while Inpari 13 produced grain containing the largest per clump in continuous inundation with the treatment of C/N manure 19.80: 1.

Conclusion

In conclusion, the study found that the treatment of water management and the provision of buffalo manure had a significant positive effect on plant growth and grain yield. The study also found that the different rice varieties responded differently to the treatment, with some varieties showing better results in terms of plant height, number of tillers, and grain yield. The study provides valuable insights for farmers in choosing optimal management varieties and methods to achieve better crop yields.

Recommendations

Based on the findings of the study, the following recommendations can be made:

Intermittent irrigation is the most effective irrigation method for rice production.
The provision of buffalo manure with a C/N ratio of 10.15: 1 is the most effective treatment for increasing plant growth and grain yield.
The different rice varieties respond differently to the treatment of water management and the provision of buffalo manure, and farmers should choose the variety that is best suited to their specific conditions.
The interaction between water management and buffalo manure has a significant effect on grain yield, and farmers should consider this when making decisions about their rice production.

Future Research Directions

The study provides a foundation for future research in the area of rice production. Some potential areas for future research include:

Investigating the effects of different types of fertilizers on plant growth and grain yield.
Examining the effects of different irrigation methods on plant growth and grain yield.
Investigating the effects of different soil types on plant growth and grain yield.
Examining the effects of climate change on rice production and developing strategies for adapting to these changes.

Limitations of the Study

The study has several limitations that should be noted. These include:

The study was conducted in a greenhouse setting, which may not accurately reflect the conditions found in the field.
The study only examined four rice varieties, and further research is needed to determine the effects of the treatment on other varieties.
The study only examined the effects of water management and buffalo manure on plant growth and grain yield, and further research is needed to determine the effects of other factors on rice production.
