The number of rural poor has been reported to rise in Sub-Saharan Africa (SSA) while per capita food consumption in the region is on the decline and food insecurity has been much embedded. Thus, knowing upgrading strategies (UPS) to be used in making a living and would have great chance of benefiting majority hence provide solutions to poverty, food insecurity and malnutrition. This paper assesses and compares the views of local stakeholders and agricultural experts in terms of prioritizing food securing UPS along food value chains (FVC). Data and information have been collected in a highly participatory process so as to develop an approach and experience in Tanzania regions to support poor people in rural areas to upgrade their position in viable FVC. Local stakeholders’ definition of food security rely on food availability component, hence this paper centers on two major FVC components such as natural resources and crop production for maize and millet subsectors in Morogoro and Dodoma regions of Tanzania, respectively. Given natural resources, agricultural experts favor soil improving upgrading strategies in Morogoro and water management in Dodoma, whereby, local stakeholders in both regions prefer farm inputs related UPS for improving soil fertility (seed varieties improvement and fertilizer use). There is no significant mismatch of views for production component apart from differences on ranks. Stakeholders in both regions prefer use of improved crop varieties, pests and diseases control and new livestock management including having village land use planning. It is recommended that satisfactory participation of local stakeholders should be considered during testing stage of FVC upgrading strategies, including packing these innovations to suit local conditions and finally empower all potential actors for successful dissemination and outreach.
Effects of fertilizer micro-dose and in situ rain water harvesting technologies on growth and yield of pearl millet in a semi-arid environment
(Springer, 2020-03) Chilagane, E. A.; Saidia, P. S.; Kahimba, F. C.; Asch, F.; Germer, J.; Graef, F.; Swai, E.; Rweyemamu, C. L.
Declining soil fertility and low rainfall are key constraints to crop production and are threatening food security in semi-arid areas. Applying inorganic fertilizer at reduced amount (micro-dose) and in situ rainwater harvesting using infiltration pits (IP) or tied ridges (TR) are low-input strategies to cope with these constraints. This work investigates the effect of integrating fertilizer with in situ rainwater harvesting technologies on pearl millet growth, yield and household profitability among Tanzanian smallholder farming communities. Split plot field experiments were conducted from 2015 to 2017 cropping seasons. Flat cultivation (FC) with zero fertilizer application resulted in lowest grain yield ranging from 297 to 453 kg/ha and in a negative net profit (NP). The highest yield of 2202 kg/ha was obtained upon the use of recommended rate under IP, but it resulted in negative NP. Infiltration pits under 25% micro-dose resulted in relative higher grain yield (778–2202 kg/ha) compared to TR (887–1915 kg/ha) and FC (592–1144 kg/ha); despite higher yield, it resulted in negative NP. Tied ridges and FC with micro-dose at 25% of recommended rate had a yield advantage ranging from 537 to 959 kg/ha and 295 to 455 kg/ha, respectively, compared to farmer practices, and both resulted in positive NP. The use of micro-dose at 25% of recommended rate along with TR or FC which gave higher grain yield and NP compared to farmers practice is recommended to resource-poor farmers for improved pearl millet productivity.
