Response to the Growth and Production of Several Sorghum Varieties (Sorghum Bicolor (L). Moench) to Different Doses of Kascing Fertilizer

Introduction

Sorghum (Sorghum bicolor (L). Moench) is a versatile crop that has been widely cultivated for its grain, biomass, and forage. It is an important crop in many parts of the world, particularly in tropical and subtropical regions. The growth and production of sorghum are influenced by various factors, including the type of sorghum variety, soil fertility, and the application of fertilizers. In this study, we investigated the response of three sorghum varieties to different doses of kascing fertilizer, a type of organic fertilizer.

Background

Kascing fertilizer is a type of organic fertilizer that is made from the waste of the kascing plant (Cassia auriculata). It is a rich source of nutrients, including nitrogen, phosphorus, and potassium. The use of kascing fertilizer has been shown to improve soil fertility and increase crop yields. However, the optimal dose of kascing fertilizer for sorghum production is not well established. Therefore, this study aimed to investigate the response of three sorghum varieties to different doses of kascing fertilizer.

Research Methodology

The study was conducted on Jalan Pasar 1 Tanjung Sari, Medan Selayang District, Medan, from July to November 2020. Three sorghum varieties, namely Numbu, Bioguma, and Super 2, were used in this study. The experiment was designed as a factorial experiment, with the first factor being the sorghum variety and the second factor being the dose of kascing fertilizer. The doses of kascing fertilizer used were 0, 7.5, 15, and 22.5 tons per hectare. The experiment was replicated three times, and the data were analyzed using analysis of variance (ANOVA).

Results

The results of this study showed that the treatment of varieties had a significant effect on plant growth, including plant height, stem diameter, flowering age, and seed weight per sample and per plot. The weight of seeds per sample, wet bar weighing, wet weight sack weight, wet root weight, and dry root weight were also significantly affected. In terms of treatment of kascing fertilizer, it was found that different doses had a significant impact on plant height at the age of 2-8 weeks after sowing (MST), stem diameter, flowering age, and seed weight. The weight of dry barren, wet root weight, and dry root weight were also significantly affected.

Interaction Analysis

The interaction between the sorghum variety and the dose of kascing fertilizer also showed a significant effect. This is reflected in the diameter of the stem, the age of flowering, and the weight of the dry safe. This study proves that the right combination of varieties and fertilizer doses is very important to achieve optimal growth. For example, some varieties may be more responsive to certain fertilizer doses, thus giving better harvests than other varieties.

Conclusion

From the research conducted, it can be concluded that the selection of sorghum varieties and the appropriate dosage of kascing fertilizer is very influential on the growth and production of sorghum. These results provide important insights for farmers and researchers who want to increase sorghum productivity through the use of organic fertilizer such as kascing fertilizer. By applying the right techniques, it is expected that sorghum agricultural products can improve, providing greater benefits for farmers and overall food security.

Recommendations

Based on the results of this study, the following recommendations are made:

Selection of sorghum varieties: The selection of sorghum varieties should be based on the specific growing conditions and the desired traits of the crop. In this study, three sorghum varieties were used, and the results showed that each variety responded differently to the different doses of kascing fertilizer.
Application of kascing fertilizer: The application of kascing fertilizer should be based on the specific needs of the crop. In this study, different doses of kascing fertilizer were used, and the results showed that each dose had a significant impact on plant growth and production.
Interaction between varieties and fertilizer doses: The interaction between the sorghum variety and the dose of kascing fertilizer should be taken into account when selecting the right combination of varieties and fertilizer doses. This study showed that the right combination of varieties and fertilizer doses is very important to achieve optimal growth.

Future Research Directions

This study provides a foundation for further research on the use of kascing fertilizer in sorghum production. Future research should focus on the following areas:

Optimization of kascing fertilizer doses: The optimal dose of kascing fertilizer for sorghum production should be determined through further research.
Interaction between kascing fertilizer and other factors: The interaction between kascing fertilizer and other factors, such as soil fertility and climate, should be investigated.
Use of kascing fertilizer in other crops: The use of kascing fertilizer in other crops, such as maize and wheat, should be investigated.

Limitations of the Study

This study has several limitations, including:

Limited number of sorghum varieties: Only three sorghum varieties were used in this study, which may not be representative of all sorghum varieties.
Limited number of kascing fertilizer doses: Only four doses of kascing fertilizer were used in this study, which may not be sufficient to determine the optimal dose.
Limited geographic scope: This study was conducted in a single location, which may not be representative of all growing conditions.

Conclusion

In conclusion, this study provides important insights into the response of sorghum varieties to different doses of kascing fertilizer. The results show that the selection of sorghum varieties and the appropriate dosage of kascing fertilizer is very influential on the growth and production of sorghum. These results provide important insights for farmers and researchers who want to increase sorghum productivity through the use of organic fertilizer such as kascing fertilizer.
