Abstract
When analyzing data on six-row barley harvest volume, planting area, and yield per 10 ares in Japanese agriculture, some interesting trends emerge. The 2021 harvest volume nationwide reached 55.1kt, the highest figure ever recorded. Similarly, the cultivated area is 18.1kha in the country, which is also the largest. On the other hand, in terms of yield per 10a, Saitama showed the highest value of 483 kg. The trend that can be inferred from these data is that demand for six-row barley may be increasing. This suggests that yields and cultivated areas are increasing accordingly. Since Saitama has achieved a high yield per 10 ares, it is possible that efficient cultivation methods and technologies are being adopted in this region. As such, production of six-row barley is showing a trend of expansion nationwide, indicating the existence of efficient production areas.
Six-row barley harvest yield (main data).
The yield of six-rowed barley in Japan has fluctuated between 1958 and 2021. The peak yield was recorded nationwide in 1959 at 1.03 Mt, but has been declining in the following decades. Current yields are about 5.35% of their peak, suggesting a long-term decline. The reasons behind this decline include structural changes in agriculture, changes in market demand, and the impact of agricultural policies. It is also possible that six-row barley production has been replaced by other crops or industries. In contrast, there may be some areas where productivity has increased in recent years through improvements in specific varieties or cultivation techniques. The decline in six-row barley yields reflects the impact of a variety of factors in Japanese agriculture, but it is important to take into account that productivity may be improving in some regions and with certain techniques.
The maximum is 1.03Mt[1959] of Japan, and the current value is about 6.32%
Six-row barley harvest volume (by prefecture).
Looking at data by prefecture for 2021, Fukui Prefecture recorded the highest six-row barley harvest in Japan at 13.3kt. This figure is the highest ever and suggests that six-row barley production is increasing. It is possible that productivity is improving in certain regions, including Fukui Prefecture. It is also possible that harvests are increasing or stabilizing in other prefectures. This trend is likely influenced by regional agricultural policies, technological innovations and shifts in demand. Six-row barley is a crop that is experiencing increasing demand due to its characteristics and utility value, so an increase in production is seen as a positive sign for the agricultural economy. On the other hand, factors such as climate change and natural disasters may affect yields. Overall, the 2021 six-row barley harvest is showing an overall increase with some notable trends in production in certain regions.
The maximum is 18.1kt of Fukui, the average is 2.4kt, and the total is 64.8kt
Area planted with six-row barley (main data).
The area of land cultivated with six-row barley in Japanese agriculture has fluctuated between 1958 and 2021. The peak cultivated area nationwide was recorded at 355 kha in 1958, but has been declining in the following decades. Current acreage is about 5.11% of the peak, suggesting a long-term decline. The reasons behind this decline include structural changes in agriculture, changes in market demand, and the impact of agricultural policies. The decline in the area planted with six-row barley may also be due to its replacement with other crops and industries. Urbanization and changes in land use may also be contributing to the decline in cultivated area. In response to this, the cultivation of six-row barley is being promoted in some regions, but the overall trend is one of continued decline. The decline in cultivated area reflects the impact of various factors on Japanese agriculture, but the introduction of sustainable agricultural policies and technological innovations could encourage an increase in cultivated area.
The maximum is 355kha[1958] of Japan, and the current value is about 5.44%
Area cultivated with six-row barley (by prefecture).
Looking at data by prefecture for 2021, Fukui Prefecture recorded the largest area planted with six-row barley in Japan, at 4.78 kha. This figure is the highest ever, suggesting that cultivation of six-row barley is increasing in certain regions, including Fukui Prefecture. Acreage in other regions may also be increasing or remaining stable. This trend is influenced by regional agricultural policies, changes in demand, and improvements in cultivation techniques. Six-row barley is a crop that is experiencing increasing demand due to its characteristics and utility value, and an increase in the production area is considered a positive sign for the agricultural economy. On the other hand, factors such as climate change and natural disasters may affect the area under cultivation. Overall, six-row barley acreage is increasing across the board in 2021, with some indications of particular interest in certain areas.
The maximum is 5.06kha of Fukui, the average is 712ha, and the total is 19.2kha
Yield of six-row barley per 10a (by prefecture).
In 2021, Saitama Prefecture recorded the highest yield of six-row barley per 10a in Japan, at 483kg. This is well above the average yield of 278kg. The total national yield was 7.22 tons, with Saitama Prefecture’s high yield having a significant impact on the overall harvest volume. The yield per 10 ares of Rokujo barley varies greatly depending on the region, and Saitama Prefecture’s high yield reflects the excellent cultivation techniques and soil conditions of the region. On the other hand, there are areas with lower than average yields, which is thought to be due to differences in cultivation techniques and environmental conditions. Yields of six-row barley may be improving due to improved varieties and agricultural techniques, but the impact varies from region to region. Additionally, climatic conditions and weather conditions also have a significant impact on yields. Overall, the yield per 10a of Rokujo barley in 2021 varied greatly between regions, with high yields recorded mainly in Saitama Prefecture, but there is still a large gap in the average yield.
The maximum is 433kg of Nagano, the average is 286kg, and the total is 8.01t
