The Development Of Weeds And The Yield Of Soybeans And Corn In The Orientation Of The Manipulated Plant Lines And Different Spacing
The Development of Weeds and Yields of Soybeans and Corn in the Orientation of the Manipulated Plant Lines and Different Spacing
Introduction
The growth of weeds and the yields of soybeans and corn are crucial factors in agricultural productivity. Weeds can compete with major plants for resources such as light, water, and nutrients, leading to reduced crop yields. Therefore, understanding the factors that influence weed growth and crop yields is essential for developing more efficient and sustainable agricultural practices. This study aims to examine the influence of manipulated plant row orientation and different spacing on weed growth and the yields of soybeans and corn.
Research Methodology
The research was conducted in Tanjung Beringin District, Serdang Bedagai Regency, North Sumatra Province, from October 2014 to February 2015. The research design used a factorial random design method (RAK) which includes two factors, namely the orientation of the plant line and planting distance, with three repetitions to ensure the validity of the results. The parameters observed in soybean plants include the percentage of weed cover, weed dry weight, light intensity, productive branches, plant height, flowering age, number of pods per plant, number of seeds per pod, weight of 100 seeds, seed weight per plant, harvest index, and results per hectare. Similarly, in corn plants, the parameters measured include the percentage of weed cover, weed dry weight, light intensity, stem diameter, plant height, number of leaves, length and diameter of cobs, number of seeds per cob, weight of 100 seeds, seed weight per plant, index harvest, and results per hectare.
Research Results
The results showed that the orientation of soybean and corn lines did not have a significant effect on weed growth or the results of the two types of plants. Specifically, in observations 75 days after planting (HST), soybean spacing 30 x 20 cm shows better capability in suppressing weed growth, with a percentage of pressure reaching 5.63% compared to a spacing of 35 x 20 cm. However, at 42 HST, spacing does not show a significant effect on the growth of soy weeds. On the other hand, corn spacing applied at 75 x 20 cm and 75 x 25 cm also does not show a significant effect on weed growth at 42 and 90 HST. Furthermore, there is no significant effect from the spacing of planting on the results of soybean and corn plants. The interaction between plant row orientation and spacing does not show a significant impact on weed growth and the results of both types of plants.
Analysis
The results of this study provide valuable insight for farmers and agronomy experts. The discovery that the orientation of the plant line does not affect the growth of weeds opens up the possibility for a more flexible planting method. Emphasis on a more dense planting distance for soybean plants shows that proper spacing regulation can help in controlling weed growth. This is important considering that weeds can compete with major plants for resources, such as light, water, and nutrients. In addition, insignificant results from the spacing of corn plants indicate that other factors, such as pest and disease management, as well as the selection of appropriate varieties, may be more influential on plant productivity. Therefore, farmers are advised to pay attention to these aspects to improve their agricultural output.
Implications and Recommendations
The results of this study have several implications for agricultural practices. Firstly, the discovery that the orientation of the plant line does not affect the growth of weeds suggests that farmers can adopt a more flexible planting method. Secondly, the emphasis on a more dense planting distance for soybean plants highlights the importance of proper spacing regulation in controlling weed growth. Finally, the insignificant results from the spacing of corn plants suggest that other factors, such as pest and disease management, as well as the selection of appropriate varieties, may be more influential on plant productivity.
Conclusion
In conclusion, this study provides valuable insight into the factors that influence weed growth and crop yields. The results suggest that the orientation of the plant line does not affect the growth of weeds, and that proper spacing regulation can help in controlling weed growth. The study also highlights the importance of other factors, such as pest and disease management, as well as the selection of appropriate varieties, in improving plant productivity. Therefore, farmers are advised to pay attention to these aspects to improve their agricultural output.
Future Research Directions
This study opens up several avenues for future research. Firstly, further research is needed to investigate the interaction between environmental factors, planting distances, and crop products. Secondly, the study highlights the importance of proper spacing regulation in controlling weed growth, and further research is needed to investigate the optimal spacing distances for different crops. Finally, the study suggests that other factors, such as pest and disease management, as well as the selection of appropriate varieties, may be more influential on plant productivity, and further research is needed to investigate these factors.
