Key Groundnut Varieties Suitable for Wholesale Export from Nigeria:

The Nigerian Institute for Oil Palm Research (NIFOR) and other agricultural research institutions have developed and promoted various groundnut varieties tailored to the country’s diverse agro-ecological zones. These varieties exhibit varying characteristics, making some more suitable for export than others. Here are some of the top contenders:

SAMNUT 21 (IAR 59): SAMNUT 21 is a highly popular and widely cultivated variety in Nigeria, renowned for its high yield potential and early maturity (approximately 90-100 days). This is a significant advantage for farmers, allowing for multiple harvests within a year. SAMNUT 21 possesses a good shelling percentage (around 70%), and the kernels are relatively large, appealing to markets seeking direct consumption and confectionery applications. It exhibits moderate resistance to rosette disease, a devastating viral infection that can significantly impact groundnut yields. While its oil content is moderate (around 48-50%), its overall performance, ease of cultivation, and market acceptance make it a reliable choice for export. The rose colored testa (seed coat) is also generally well-received. Its adaptability to various soil types across the savanna regions of Nigeria further contributes to its widespread cultivation.

SAMNUT 22 (IAR 637): Developed as an improvement upon earlier varieties, SAMNUT 22 boasts a higher yield potential and improved resistance to foliar diseases like leaf spot. It also maintains a relatively early maturity period. Its oil content is comparable to SAMNUT 21. The improved disease resistance translates to reduced reliance on pesticides, leading to more sustainable farming practices and potentially lower production costs. Its larger kernel size compared to some other varieties also makes it a more attractive option for certain export markets. Its relatively good shelling percentage further enhances its value proposition.

The smaller kernel size might be suitable for specialized applications or regional markets where smaller groundnuts are preferred.

SAMNUT 24 (IAR 639): SAMNUT 24 is another high-yielding variety with good resistance to rosette disease. Its kernel size is relatively large, and the shelling percentage is also favorable. This variety performs well in drier regions and has good drought tolerance, making it a viable option for areas with limited rainfall. The combination of drought tolerance and disease resistance contributes to its reliability and stability in terms of yield. Its broad adaptability makes it a favorable choice for farmers across different agro-ecological zones.

RRB (Red Runner Bunch): While RRB might be a broad category rather than a specifically registered variety in Nigeria, Red Runner types are generally known for their high yield and suitability for processing. The "bunch" refers to the plant’s growth habit, which is more compact and upright than sprawling varieties. Red Runner groundnuts are often favored for blanching, a process where the red skin (testa) is removed. Blanching is crucial for producing certain peanut products like peanut butter and confectionery items. Exporters should carefully source Red Runner groundnuts from reputable growers who adhere to good agricultural practices to ensure quality and traceability. The reddish-brown seed coat is characteristic of these types.

SUNFLOWER: Though the name might mislead, Sunflower is a registered groundnut variety in Nigeria. It stands out due to its relatively short maturity period (around 90 days) and high oil content. This variety can be particularly attractive for farmers seeking a quick turnaround and targeting the oil processing market. Its shorter growth cycle also allows for multiple cropping seasons, increasing overall productivity. However, the yield of Sunflower might be slightly lower compared to some other varieties like SAMNUT 21.

Manipintar: This Spanish-type groundnut is known for its small to medium-sized kernels and its high oil content. Spanish-type groundnuts, in general, blanch well and are frequently used in the confectionery industry. They often have a distinctive, slightly sweet flavor. Manipintar’s compact growth habit can make it suitable for higher-density planting. While not as widely cultivated as some of the SAMNUT varieties, Manipintar can be a valuable niche variety for exporters targeting specific markets that demand Spanish-type groundnuts.
