Effect of Seed Bulbs Weight and KCl Fertilizer Dosage on Potato Growth and Production

Introduction

Potatoes (Solanum tuberosum L) are one of the most widely cultivated crops globally, providing a vital source of food for millions of people. The growth and production of potatoes are influenced by various factors, including the weight of seed tubers and the dose of potassium chloride fertilizer (KCl). This study aims to investigate the effect of seed tuber weight and KCl fertilizer dosage on potato growth and production.

Methodology

This study was conducted at Ujung Sampun, Tanah Karo, North Sumatra, at an altitude of about 1250 meters above sea level, from August to November 2007. The method used was a randomized factorial group with two factors. The first factor is the weight of seed tubers with four levels, namely: 25-30 g (B1), 35-40 g (B2), 45-50 g (B3), and 55-60 g (B4). The second factor is the dose of KCl fertilizer with three levels, namely: 0 kg (K0), 5.3 g (K1), and 10.6 g (K2).

Results

The results of the study show that:

Seed tuber weight has a significant effect on several parameters such as the weight of the tubers per sample, the weight of the tubers per plot, the total tubers per sample, the number of tubers class A, B, C, D, and production per hectare. However, the weight of seed tubers does not have a significant effect on plant height.
KCl fertilizer dose has a significant effect on tuber weight per plot, the number of tubers class C and D. However, the dose of KCl fertilizer does not have a significant effect on plant height, tubers per sample, total tubers per sample, the number of tubers class A, B, and production per hectare.
Interaction between the weight of the seedlings and the dose of KCl fertilizer has a significant effect on the weight of the tubers per plot. However, this interaction does not have a significant effect on the height of the plant, the weight of the tubers per sample, the total tubers per sample, the number of tubers class A, B, C, D, and production per hectare.

Further Analysis

The results of this study indicate that the use of heavier seed tubers has a positive effect on several parameters of potato production. This shows that the size of the seed tubers has a strong correlation to the growth and production of potatoes.

Although the dose of KCl fertilizer does not have a significant effect on several production parameters such as production per hectare, the effect on the weight of the tubers per plot and the number of class C and D tubers indicates that KCl fertilizer can contribute to improving the quality of tubers.

The interaction between the weight of the seed tubers and the dose of KCl fertilizer which only affects the weight of the tubers per plot shows that the influence of the two factors is not additive.

Implications for Farmers

This research has several implications for potato farmers:

Choose seed tubers with a bigger weight to get better harvests.
Use KCl fertilizer with the right dose to improve the quality of tubers.
Consider the use of seed tubers with a certain weight to get maximum results with a certain dose of KCl fertilizer.

Conclusion

This study shows that the weight of seed tubers and KCl fertilizer doses has a significant effect on the growth and production of potatoes. The use of more severe seed tubers and the right dose of KCl fertilizer can increase crop yields and tuber quality. The findings of this study can provide valuable information for potato farmers to improve their crop yields and tuber quality.

Recommendations

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

Further research should be conducted to investigate the effect of other factors on potato growth and production.
Potato farmers should consider using heavier seed tubers and the right dose of KCl fertilizer to improve their crop yields and tuber quality.
The interaction between the weight of the seed tubers and the dose of KCl fertilizer should be further investigated to determine the optimal combination of these factors for maximum results.

Limitations of the Study

This study has several limitations, including:

The study was conducted in a specific location and may not be representative of other locations.
The study only investigated the effect of seed tuber weight and KCl fertilizer dosage on potato growth and production, and did not consider other factors that may influence these parameters.
The study only used a randomized factorial group design, which may not be the most effective design for investigating the interaction between the weight of the seed tubers and the dose of KCl fertilizer.

Future Research Directions

Based on the findings of this study, the following future research directions are suggested:

Investigate the effect of other factors on potato growth and production, such as soil type, climate, and irrigation.
Conduct further research to determine the optimal combination of seed tuber weight and KCl fertilizer dosage for maximum results.
Investigate the interaction between the weight of the seed tubers and the dose of KCl fertilizer in different locations and under different conditions.
