Response to the Growth and Production of Several Varieties of Corn (Zea mays L.) to the Administration of P and K Fertilizer

Introduction

The growth and production of corn (Zea mays L.) are crucial for food security and economic development in many countries, including Indonesia. Corn is a staple crop in Indonesia, and its production is influenced by various factors, including the type of fertilizer used. Phosphorus (P) and Potassium (K) fertilizers are essential nutrients for corn growth, and their adequate supply can significantly impact crop yields. This article discusses the response of several corn varieties to the administration of P and K fertilizers, highlighting the importance of fertilizer management in optimizing corn growth and production.

Background

Corn is a widely cultivated crop in Indonesia, and its production is influenced by various factors, including climate, soil type, and fertilizer management. The use of P and K fertilizers is essential for corn growth, as these nutrients play a crucial role in plant development and yield formation. However, the optimal application of P and K fertilizers can vary depending on the type of corn variety, soil type, and climate. Therefore, understanding the response of corn varieties to P and K fertilizers is essential for optimizing corn growth and production.

Research Methodology

This study was conducted to investigate the response of several corn varieties to the administration of P and K fertilizers. The research was conducted at UPT BBI Tanjung Selamat, Deli Serdang Regency, North Sumatra Province, at a land height of about 25 meters above sea level, from May to August 2012. The method used was a random block design with two replications, involving two varieties of corn, namely Bisma and SHS-4, with a dose of fertilizer determined through Central Composite Rotatable Design (CCRD). Some of the parameters measured include plant height, number of leaves, time of interest initiation, harvest age, cob length, number of leaves on a cob, cob diameter, weighing 100 seeds, seed filling rates, and dry seed production.

Research Results

The results showed that there were significant differences between corn varieties in terms of plant height, number of leaves, harvest age, cob diameter, 100 grains, seed filling rates, and dry seed production. This shows that different corn varieties have different adaptability to growth and fertilization conditions. In addition, the administration of P and K fertilizer also has a significant effect on plant height, number of leaves, and dry seed production. This indicates that adequate nutrition from P and K fertilizer is very important to increase the growth and yield of corn.

Varieties and Fertilizer Interactions

The interaction between varieties and fertilizer also has a significant effect on plant height, cob diameter, and dry seed production. This shows that not only the quality of varieties that play a role in the success of growth, but also the type and amount of fertilizer given. Some varieties may be more responsive to certain types of fertilizers, so that proper fertilization management can increase the overall harvest.

Conclusion

This study provides important insights for farmers and researchers in optimizing corn growth through the selection of varieties and the provision of appropriate fertilizer. By understanding the response of corn varieties to fertilization, it is expected that corn production in Indonesia can increase, contribute to national food security. Therefore, it is essential for farmers to consider the results of this study in their cultivation practices, in order to maximize quality corn farming.

Implications for Farmers and Researchers

The findings of this study have significant implications for farmers and researchers in optimizing corn growth and production. The results suggest that the selection of corn varieties and the provision of appropriate fertilizer are crucial for maximizing corn yields. Farmers should consider the results of this study in their cultivation practices, taking into account the type of corn variety, soil type, and climate. Researchers should also consider the findings of this study in their future research, focusing on the development of new corn varieties and fertilizer management strategies that can optimize corn growth and production.

Future Research Directions

Future research should focus on the development of new corn varieties that are more responsive to P and K fertilizers. Additionally, research should be conducted on the optimal application of P and K fertilizers, taking into account the type of corn variety, soil type, and climate. Furthermore, research should be conducted on the use of other fertilizers, such as nitrogen (N), to optimize corn growth and production.

Limitations of the Study

This study has some limitations that should be considered. The study was conducted on a small scale, and the results may not be generalizable to other regions or countries. Additionally, the study only focused on two corn varieties, and the results may not be applicable to other varieties. Therefore, future research should be conducted on a larger scale, involving multiple corn varieties and fertilizer management strategies.

Conclusion

In conclusion, this study provides important insights for farmers and researchers in optimizing corn growth through the selection of varieties and the provision of appropriate fertilizer. The results suggest that the administration of P and K fertilizer has a significant effect on plant height, number of leaves, and dry seed production. Therefore, it is essential for farmers to consider the results of this study in their cultivation practices, in order to maximize quality corn farming.
