Growth and Production of Corn at Various Planting Distances and Competition with Paraquat Resistance

Introduction

The growth and production of corn (Zea mays L.) are influenced by various factors, including planting distance and competition with weeds. In this study, we aimed to investigate the effect of planting distance and weed density on the growth and production of corn varieties DK 77, with a focus on the competition with Eleusine indica L. (loungeers) resistant paraquat. The study was guided by Edison Purba and Chairani Hanum, and the results provide valuable insights for agricultural practices.

Research Methodology

This study employed a random design method with three treatment factors and four replications to produce accurate data. The treatment factors included variations in spacing, weed population density, and the characteristics of weeds themselves. The data collected included growth parameters such as plant height, number of leaves, and production parameters such as the number of cobs, seeds per cob, and chlorophyll content.

Research Results

The results showed that the planting distance had a significant effect on all growth parameters and corn production, except in the parameters of chlorophyll content and the number of rows in cobs. This means that the selection of the right spacing can increase the overall productivity of corn. In addition, for weed parameters, spacing also has a significant effect on the number of weed puppies per clump, the number of weed productive puppies, and the number of weeds in the middle and end population. This shows that the management of planting distance is not only important for corn plants, but also to control weed growth.

Weed density has a significant effect on all parameters except stem diameter, chlorophyll content, and the number of rows in cobs. This finding indicates that the higher the weed density, the greater the impact on corn growth, especially in terms of nutritional competition and light. The interaction between the spacing and weed density, as well as between the spacing and the characteristics of weeds, showed a significant effect on some of the observed parameters. This reflects the importance of understanding the dynamics between plants and weeds in the context of sustainable agriculture.

Analysis and Recommendations

The results of this study provide valuable insights for agricultural practices, especially in the management of corn growth in conditions of competition with weeds. To increase the production of corn production, it is recommended that farmers pay attention to the right spacing and control weeds effectively, especially for resistant weeds such as loungeers. The management of planting distance is crucial not only for corn plants but also to control weed growth.

Furthermore, the results of this study can be the basis for further research on weed control strategies that are more effective and environmentally friendly. The development of sustainable agriculture practices is essential for improving food security and reducing the environmental impact of agricultural activities.

Conclusion

In conclusion, this study provides valuable insights for agricultural practices, especially in the management of corn growth in conditions of competition with weeds. The results of this study highlight the importance of understanding the dynamics between plants and weeds in the context of sustainable agriculture. By optimizing the planting distance and controlling weeds effectively, farmers can improve the production of corn and contribute to food security.

Implications for Sustainable Agriculture

The results of this study have significant implications for sustainable agriculture practices. The management of planting distance and weed density is crucial for improving the productivity of corn and reducing the environmental impact of agricultural activities. The development of sustainable agriculture practices is essential for improving food security and reducing the environmental impact of agricultural activities.

Future Research Directions

The results of this study provide a basis for further research on weed control strategies that are more effective and environmentally friendly. The development of sustainable agriculture practices is essential for improving food security and reducing the environmental impact of agricultural activities. Future research should focus on the development of integrated pest management (IPM) strategies that combine physical, cultural, biological, and chemical controls to manage weeds and improve crop productivity.

Recommendations for Farmers

The results of this study provide valuable insights for farmers, especially in the management of corn growth in conditions of competition with weeds. To increase the production of corn production, farmers should pay attention to the right spacing and control weeds effectively, especially for resistant weeds such as loungeers. The management of planting distance is crucial not only for corn plants but also to control weed growth.

Limitations of the Study

This study has some limitations that should be considered when interpreting the results. The study was conducted in a controlled environment, and the results may not be generalizable to other environments. Furthermore, the study focused on the effect of planting distance and weed density on the growth and production of corn varieties DK 77, and the results may not be applicable to other corn varieties.
