Innovafrica-Sorghum-Legume trials lindi

Ensuring food security in small-scale farming requires improvement of
productivity of food crops to ensure access of food in local
communities. the objective of the sorghum-legume demonstration
trial was to demonstrate the performance of proven Sustainable
Agricultural Intensification (SAI) practices in terms of yield, soil
quality and labour efficiency. A farmers-led field trails were conducted
in Nachunyu and Mmumbu villages in Lindi district, Tanzania. The SAI
technologies validated include:  i) Treatment 1: Conventional
tillage – farmers practice, consisting of hand hoe cultivation, residue
were removed, no herbicides applied (hand hoe weeding) and continuous
sorghum  ii) Treatment 2: Conservation tillage dibble stick,
retention of crop residues but no herbicide use (traditional weeding), and
cropping system of continuous sorghum, applied fertilizers and no burning
of residues; iii) Treatment 3: Conservation tillage using dibble stick,
retention of crop residues, applied herbicide immediately after planting ,
but continuous sorghum, applied fertilizer (NPS) and no burning of
residues; iv) Treatment 4: Conservation agriculture with legume-sorghum
rotation, tillage dibble stick, retention of crop residues, apply
herbicide roundup soon after planting followed by traditional hand hoe
weeding when needed after crop germination, apply fertilizers (NPS),
started with sorghum in  season one (1) 2017/18. Soil samples
were collected before the trials and after the trials. Data collected
includes grain yields and residue biomass.
