Optimizing Maize Planting Date, Plant Population, And Fertilizer Application Rates For Lesotho Subsistence Farmers, Matthew Ryan Bruns
Masters Theses
Due to perpetually low yields, smallholder farmers throughout Southern Africa plow increasingly large plots of land in an attempt to increase their household food security. However, extensive agriculture further depresses yields because expensive inputs are spread over a larger area, provides little soil cover, and results in high soil erosion rates. To address these challenges, farmers in the Kingdom of Lesotho are beginning to adopt conservation agriculture (CA) systems. Under CA and conventional tillage systems the optimum plant population, planting date, and fertilizer rates are unknown. The effects of field preparation, planting date, weed control strategies, plant populations, and nitrogen …
