Regional Analysis

Asia-Pacific Dominates the Global Market

The global onion seed market is bifurcated into four regions: North America, Europe, Asia-Pacific, and LAMEA.

Asia-Pacific is the most significant revenue contributor and is expected to grow at a CAGR of 5.2% during the forecast period. Some regions in China, like Gansu, Inner Mongolia, and others, recently made significant investments in the production of onions. In comparison to 2019, these two regions' cultivation increased by 15% to 20% in 2020. As a result, the demand for oil seeds increased in these regions during the study period. The yellow dwarf virus has caused some of the nation's onion-growing areas to experience a fall in yield. As a result, the nation's onion farmers may demand virus-resistant onion seeds in the upcoming years. This could cause the market to rise significantly. One of the biggest onion producers in the nation is Shandong. As a result, to expand their market potential in China, multinational corporations are concentrating on the Shadong region.

Furthermore, major onion-producing states include Maharashtra, Karnataka, Madhya Pradesh, Gujarat, Bihar, Andhra Pradesh, Rajasthan, Haryana, and Telangana. Onion seeds are in high demand throughout the nation. The varieties found in India include Agrifound Dark Red, Agrifound Light Red, NHRDF Red, Agrifound White, Agrifound Rose, Agrifound Red, Pusa Ratnar, Pusa Red, and Pusa White Round. Yellow onion cultivars in India include Tana F1, Arad-H, Suprex, Granex 55, HA 60, and Granex 429, all acceptable for export to European nations. Due to rising bulb prices on the domestic market and worries about a seed shortage before the upcoming sowing season, the government immediately banned the export of onion seeds. Agricultural universities and businesses are concentrating on introducing new products to grow the market.

North America is expected to grow at a CAGR of 5.00% during the forecast period. Hybrid onions account for roughly 90% to 95% of production in the United States because they are more homogeneous for desired features and consistently produce higher yields than open-pollination species. Traditional plant breeding methods have generated both hybrid and OP onions. More than 70% of the country's land is used to produce onions, with Tamaulipas, Chihuahua, Zacatecas, Baja California, Puebla, Michoacán, and Guanajuato making up the majority of that area. Although many different types of onions are grown, dry onions remain the foundation of production in these areas.

Tamaulipas is now one of the top states in the nation for producing white, yellow, and red onions, thanks to a considerable increase in onion production over the years. 90% of the domestically produced onions are white, 7% are purple, and 3% are yellow. 88% of production is used for fresh consumption, while 12% is used for processing (seasoned, seasoned, flaked, dried, granulated, chopped, or sliced). These elements are causing the nation's market for white onion seeds to expand. Mexico's onion crop is grown in the autumn-winter (AW) and spring-summer (SS) cycles. Eighty percent of the acreage is irrigated, and twenty percent is watered by rainfall, ensuring a year-round supply of fresh vegetables. Some onion types in the nation resistant to pink root include Buffalo, Cardinal, Caribou, NuMex Starlite, Ibex, and Nikita. In addition, some of the spring-planted cultivars with solid demand in Mexico include Aspen, Caballero, Utopia, Armada, Navigator, and Vega.

In the Russian market, onions of superior quality are becoming more expensive. As a result, throughout the study period, farmers in the nation began to choose high-yielding cultivars, which is anticipated to intensify over the forecast period. One of the most popular cultivars from the Cora Seeds firm in Russia is Elenka. It is a hybrid with four thick peel layers and a distinctive bronze color. This indicates that the bulb is exceptionally durable, a feature highly valued in Russia. The onions can be kept in units in stacks that are 6-7 meters high. Elenka is renowned for its rustic appearance, rounded shape, and well-liked hue among customers and merchants. The nation is heavily dependent on imports for its supply of onion seeds. As a result, businesses have several opportunities to grow their presence in Russia.

Additionally, the FAO reports that since 2017, the average output of the onion crop has been continuously declining. For instance, the average production of onions in 2017 was 43.35 metric tons per hectare, but due to the rise in pests and illnesses, it fell to 40.16 metric tons per hectare. Therefore, there is a lot of room for businesses to introduce disease- and pest-resistant onion seed varieties in the UK in the upcoming years. Most of the onions produced in the UK are grown on sandy soil types in the counties of Suffolk and Norfolk. Along with being the driest, this region of the nation is ideal for cultivating onions.

Brazil has a strong onion farming industry, but the prevalence and severity of downy mildew are restricting production. One of the most prevalent diseases in southern Brazil is the downy mildew disease brought on by Peronospora destructor in onions. According to a report, the nation lacks any commercially available disease-resistant cultivars. The emphasis on research and development for marketable disease-resistant onion varieties may fuel the country's market growth. 696,840 metric tons of onions are produced annually in Argentina over 27,214 acres of land. The central onion-producing regions in the nation are the north and south of Buenos Aires province, which has 8,000 hectares of medium onions, and the west (Rio Negro), which has 2,500 hectares.

Short-day cultivars are primarily grown in the northern regions for the local market. At the same time, intermediate and long-day variants are planted in the southern and western regions for domestic and foreign markets. In 2020, the nation will export 191,540 metric tons of onions to Chile, Brazil, Paraguay, and Uruguay. Onion production and export have recently faced difficulties in the country due to several issues, including logistical, economic, climatic, and soil-related diseases. On the land, onions are typically preserved beneath the plastic. Onions must be dried on the ground and preserved if they are grubbed by unexpected rains. The quality of onions is harmed by climate changes, such as the nation's constant rain and storms and inappropriate storage conditions.
