Improved vegetable production and mulching technology


These materials (manual and two presentations) were created by a graduate student as part of a Trellis Fund project, led by the Horticultural Research and Training Institute in Tengeru (HORTI Tengeru).


The original purpose of this manual was to aid Tanzanian farmers on improved practices in vegetable production, though information may be applicable to other areas. The goal of this Trellis Fund project was to improve malnutrition in Arumeru district of Tanzania, specifically for children under five years of age, through increased consumption of micro-nutrient-rich vegetables. As part of the Promotion of mulching in vegetable production Trellis Fund project, farmer motivators and farmers were trained on improving vegetable production and mulch use in farming systems. These materials focus on three vegetables: Tomato-variety Tanya, African Eggplant variety DB3 and African Nightshade – local variety.

All materials (manual and presentations) are available in Swahili. For a full citation list, please refer to the English versions.
