Sources of nitrogen in a Napier grass/legume mixture on smallholder dairy farms in central Kenya

摘要：

In Kenya, dairy production is a major source of smallholder farm income, especially in recent years after the collapse of coffee prices.The smallholder dairy systems are characterised by low weight gains in young stock and low milk production (5‐6 kg cow‐1 day‐1 ).The low yields are attributed to inadequate year‐round feed supply, protein and energy intake.The main source of forage is Napier grass ( Pennisetum purpureum ) grown in monoculture.A Napier grass/forage legume mixture can address the constraints to forage yield as the legumes have the ability to fix atmospheric nitrogen (N) through their symbiotic association with rhizobia (Giller, 2001).
