Forage Development In The Nepal Mid-Hills: New Perspectives, A. D. Robertson

IGC Proceedings (1977-2023)

Nepali hill farming communities are typically poor and remote, and are currently severely affected by conflict. The challenge is to define simple approaches which can generate results within this context. Livestock are central to livelihoods and to the sustainability of farming, with rain-fed agriculture dependent on inputs of manure-based compost. Stall feeding has increased dramatically with the adoption of community forestry and general preclusion of grazing. A broad landscape approach to forage development is increasingly being adopted, with concurrent on-farm interventions, such as intercropping and back-yard forage, and off-farm interventions, such as landslide stabilisation with forages, development of forest understory, …

Factors Influencing The Adoption Of Fodder Production Techniques By Milk Producers In Dhankuta District, Eastern Nepal, C. P. Ferris, R. Nelson

Sustaining Grass-Legume Pastures For Cow-Calf Herds: A Case Study, John L. Caddel, D. D. Redfearn, R. L. Woods

IGC Proceedings (1977-2023)

An on-going pasture demonstration study has been used since 1988 to demonstrate methods to improve pasture production for small beef cow-calf herds. Many cattle enterprises are not economically viable because poor management decisions lead to excessive stocking rate, ineffective fertilisation programmes etc., leading to a dependence on hay purchases. The initial objective, continued until 2001, was to maintain one cow- calf pair per ha without purchasing forage or grain produced off farm. More recently, reducing the dependence on harvested forage has been added as an objective.
