The Growth and Production Response of Various Rice Varieties with a Dose of Cow Manure in Rain-Fed Rice Fields

Introduction

Rain-fed rice fields are a crucial component of agricultural production in many parts of the world. However, the growth and production of rice in these fields can be affected by various factors, including the planting system, rice varieties, and the use of cow manure as a fertilizer. This study was conducted to investigate the response of various rice varieties to different levels of cow manure dosage in two planting systems in rain-fed rice fields.

Methodology

This study was conducted in Dalu X.B Village, Tanjung Morawa District, Deli Serdang Regency, with a height of ± 20 m above sea level, starting from December 2009 to April 2010. The study used a divided plot design with three replications. The treatment consisted of three factors: Planting System (S), Varieties (V), and Dosage Level of Cow Manure (K). The Planting System (S) had two levels: Planting System 1 (S1) and Planting System 2 (S2). The Varieties (V) had three levels: Ciherang (V1), Bestari (V2), and Sintanur (V3). The Dosage Level of Cow Manure (K) had five levels: Without Cow Manure (Control) (K0), 5 tons.ha-1 (3 kg/plot) (K1), 10 tons.ha-1 (6 kg/plot) (K2), 15 tons.ha-1 (9 kg/plot) (K3), and 20 tons.ha-1 (12 kg/plot) (K4).

Results

The results of the study showed that the Planting System 2 (S2) produced higher rice production compared to the Planting System 1 (S1). The Sintanur and Bestari varieties showed better growth and production than the Ciherang variety. The dose of cow manure 15 tons.ha-1 produced higher crop production compared to the dose of 20 tons.ha-1, 10 tons.ha-1, 5 tons.ha-1, and control. This shows that the use of cow manure can increase rice production, but it should be noted that a dose that is too high can actually have a negative impact.

Deeper Analysis

This study provides important information about the effect of the planting system, rice varieties, and doses of cow manure on the growth and production of rice in rain-fed rice fields. The results of the study show that the Planting System 2 is more effective in increasing rice production. This may be caused by differences in water management, nutrition, or other factors that have not been further investigated. The Sintanur varieties show the best results, possibly because it has tolerant properties of drought and the ability to absorb better nutrition. The provision of cow manure is proven to increase production, but it should be noted the right dose to avoid negative impacts.

Suggestion

This study can be followed by studying other factors that affect the growth and production of rice, such as manure types, fertilizer application time, and soil conditions.

Benefit

This study provides useful information for farmers in choosing adaptive rice varieties and determining optimal dosage of manure to increase rice production in rain-fed rice fields.

Conclusion

This study proves that Sintanur varieties are a better choice for planting systems in rain-fed rice fields. The dose of 15 tons of cow manure.ha-1 produces higher rice production and is the optimum dose for the three varieties studied.

Recommendations for Future Research

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

Investigate the effect of different manure types on rice production: This study only used cow manure as a fertilizer. Future research should investigate the effect of different manure types, such as chicken manure or pig manure, on rice production.
Study the effect of fertilizer application time on rice production: This study only investigated the effect of cow manure dosage on rice production. Future research should study the effect of fertilizer application time on rice production.
Investigate the effect of soil conditions on rice production: This study only investigated the effect of planting system, rice varieties, and cow manure dosage on rice production. Future research should investigate the effect of soil conditions, such as pH and nutrient levels, on rice production.

Limitations of the Study

This study has several limitations that should be noted. Firstly, the study only used a divided plot design with three replications, which may not be sufficient to capture the full range of variation in rice production. Secondly, the study only investigated the effect of cow manure dosage on rice production, and did not investigate the effect of other factors, such as water management and fertilizer application time. Finally, the study only used a limited number of rice varieties, and did not investigate the effect of other varieties on rice production.

Future Directions

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

Develop more adaptive rice varieties: This study shows that Sintanur varieties are a better choice for planting systems in rain-fed rice fields. Future research should focus on developing more adaptive rice varieties that can tolerate drought and other environmental stresses.
Optimize cow manure dosage: This study shows that the dose of 15 tons of cow manure.ha-1 produces higher rice production and is the optimum dose for the three varieties studied. Future research should focus on optimizing cow manure dosage to maximize rice production.
Investigate the effect of other factors on rice production: This study only investigated the effect of planting system, rice varieties, and cow manure dosage on rice production. Future research should investigate the effect of other factors, such as water management and fertilizer application time, on rice production.
