Nigerian Savanna Farm Planner

Nigeria is Africa's largest agricultural economy and the world's leading producer of yams, cassava, and several other tropical crops. The country's agricultural belt spans the Guinea and Sudan savanna zones, where 600-1,200mm of seasonal rainfall supports diverse cropping systems that feed over 200 million people.

Nigeria produces over 45 million tonnes of yams annually, more than 70% of global production. Yam farming is labor-intensive, requiring mound preparation, staking, and careful harvest, but remains culturally and economically central to agriculture in the middle belt and southern savanna regions.

Cassava is Nigeria's most widely grown crop by volume, with production exceeding 50 million tonnes. Cassava's drought tolerance and ability to grow in poor soils make it a food security crop, while processing into garri, fufu, and industrial starch adds value. The crop's flexibility means it fits into almost any farming system as either a primary or secondary crop.

Nigerian savanna agriculture is characterized by mixed cropping systems where multiple crops share the same field. A typical plot might combine sorghum or millet with cowpeas, groundnuts, and scattered trees like shea and locust bean. This polyculture approach minimizes risk, improves nutrition, and maintains soil fertility through the nitrogen-fixing contribution of legumes.

The farming calendar revolves around the single rainy season (April-October in the south, June-September in the north). Land preparation begins with the first rains, and farmers must time planting precisely to match crop water needs with rainfall patterns. Early-maturing varieties of millet and cowpea are planted first, followed by longer-season sorghum and groundnuts.

Guinea fowl and poultry production is an important component of savanna farming systems. Guinea fowl, native to West Africa, are well-adapted to the savanna environment and provide both eggs and meat with minimal inputs. They also serve as pest control, consuming insects and ticks around the farm. Integrating poultry with crop production creates a synergistic system.
