Economic viability of improved fodder production in Iringa region: comparative cost – benefit analysis of different on-farm treatments
(Eastern and Southern Africa Journal of Agricultural Economics and Development, 2022-06) Mbwaga, A. I.; Mgeni, C. P.; Kadigi, R. M. J.
Inadequate fodder production and availability has been a challenge to the livestock farmers in Tanzania. This study assessed the economic viability of fodder production using on-farm treatments at ASAS farm in Iringa region. A Completely Randomized Design was employed to arrange 24 sub-plots (six treatments and four replications) in plots of 10m x 10m dimension making a 100m 2 which is equivalent to 0.025 acres. Sub-plots were spaced each at 0.5m apart from the adjacent plot by a 1m wide path around the plot’s boundaries receiving different treatments of fertilizer. The total area for Rhodes’s grass (Chloris gayana) study was 2835m 2 . The seeds were sown in each plot and fertilizers were applied in Treatment two -Cattle Farm Yard Manure (T2-CFYM), T3 (CFYM)+Nitrogen, Phosphorus, Sulphur, and Zinc (NPSZn), T4 (NPSZn), T5 (NPSZn)+Sulphate of Ammonium (SA) and T6 (NPSZn + Urea) while T1 remained as a control (no fertilizer). Through Microsoft Excel, Cost-Benefit Analysis was done to assess the economic viability of each treatment. The study findings revealed that Treatment 3 and Treatment 6 of the experiments yielded positive Net Present Values (NPVs) of TZS 346 601.3 and TZS 1 324 442; Benefit Cost Ratios (BCRs) of 1.46 and 1.72; and Internal Rates of Return (IRR) of 15% and 16%, respectively. It is concluded that the application of T3 and T6 to the Rhodes grass would improve fodder profitability. It is recommended that with the experiment, large and smallholder farmers may produce enough fodder for themselves and surplus for sale to other livestock keepers.
Kilombero cluster development framework (KCDF) In-depth value chain analysis
(FORCONSULT & BACAS CONSORTIUM- Sokoine University of Agriculture, Morogoro, 2023-07) Munishi, P. K. T.; Kashaigili, J. J.; Abdallah, J.; Kadigi, R. M. J.; Mutabazi, K.; Hieronimo, P.; Chunga, C.
The report presents an in-depth analysis of prioritized value chains with the Kilombero Cluster. The analysis maps the core functions of the value chain the key value chain actors, business service providers and supportive stakeholders for value chains development. An in-depth analysis of the value chains overlays key performance measures including volume of transactions, costs and revenue. The analysis establishes trends and development futures of the value chains in terms of demand shaped by mega-trends such as population, income, urbanization and climate change. The report presents the dynamics of the value chains, investment opportunities, and green growth opportunities and constraints. It further explores policy and planning spaces available and reforms for addressing the critical value constraints.
Land fragmentation, agricultural productivity and implications for agricultural investments in the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) region, Tanzania

There are polarized evidences of the impact of agricultural land fragmentation on land productivity. On the one hand there viewpoints which consider land fragmentation to harm agricultural productivity. On the other hand there are counter thoughts which view land fragmentation as a positive situation which allows farmers to cultivate many environmental zones, minimise production risk and optimise the schedule for cropping activities. We use the case of Ihemi cluster in the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) to investigate the impact of land fragmentation on crop productivity. We furthermore discuss the nature and causes of land fragmentation in the SAGCOT region and its implication on the future structure of agricultural landholdings and welfare of smallholder farmers in the region. The results showed that the nature and level of fragmentation in the study area were the outcome of combined, rather than isolated influences of supply and demand driven factors. Overall, the results did not support the claim that fragmentation reduces land productivity. This then implies that land fragmentation should not always be considered as defective. There were evidences of increasing chunks of land owned by rich farmers and investors which increased the possibility for increased consolidation of agricultural land under large scale farming. However, the landholdings for smallholder farmers might become increasingly more fragmented as poor smallholder farmers continue selling their land holdings to rich farmers and investors. Releasing the SAGCOT region’s potential for agricultural development will require that smallholder farmers are helped to secure adequate and suitable land for farming, raise agricultural productivity, diversify their sources of income, and adopt good production practices. This requires setting up a strong base of investor - farmer synergies for inclusive agricultural growth.
