On-farm Pre-extension Demonstration of Newly Released Pigeon pea (Cajanus cajan) Technology with Proper Agronomic Practices in Gamo and Konso Zones of Southern Ethiopia

Abstract

Pigeon pea is widely cultivated by Ethiopian farmers, but its production remains low despite suitable conditions. This is partly due to inadequate demonstration of new pigeon pea varieties with proper agronomic practices. To address this, Arba Minch Agricultural Research Center released a new variety, Ashenafi, which showed promise in adaptation trials. However, its farmer preference and socio-economic benefits were not assessed. Therefore, a pre-extension demonstration of Ashenafi and a local check was conducted in 2024 at Karat Zuria and Boreda districts to improve pigeon pea production. The demonstration covered 20 farmers’ fields and 2 Farmers Training Centers, with 10m x 50m plots for each variety, using a spacing of 1.2m between rows and 0.5m between plants, a seed rate of 3 kg/ha, and a fertilizer rate of 100 kg/ha NPS. Grain yield data and farmer preferences were collected and analyzed. Ashenafi yielded 1,860 kg/ha compared to the local variety's 1,065 kg/ha at Karat Zuria, and 1,785 kg/ha compared to 890 kg/ha at Boreda. Results at the Farmers Training Center were similar. The significant yield gap of 787 kg/ha suggests a need to encourage adoption of the new variety. Ashenafi proved more profitable and was preferred by farmers for its earliness, quick branch emergence, seed size, grain yield, and pod number. Thus, Ashenafi is recommended for wider production with proper agronomic practices.
