dc.description.abstractLow soil fertility and drought condition are main crop production challenges that threatening food security in semi-arid areas. Use of fertilizer at micro dose rates together with in-situ rainwater harvesting using infiltration pits (IP) or tied ridges (TR) are lowinput strategies to cope with these challenges. This research was conducted to investigate effects of integrating fertilizer micro dose rates and in-situ rainwater harvesting using IP and TR on groundnut yield and its household profitability to Tanzania smallholder farming groups. Field experiments were conducted from 2015/2016 to 2016/2017 cropping seasons. Infiltration pits and tied ridges increased groundnut yield significantly by 20.2 to 32.6 % and 34.2 to 46.6% respectively over flat cultivation. Fertilizer micro dose at 50% of recommended rate significantly increased yield by 50.8 to 64.7 % over zero application. Integration of TR with fertilizer at RR resulted into highest groundnut yield ranged from 1,034 to 1,096 kg/ha and highest NP ranged from 1,027 to 1,081 USD/ha. The integrations of TR and fertilizer micro dose at 50% of recommended had significant higher yield ranged from 748 to 1,086 kg/ha and higher NP ranging from 405 to 662 USD/ha compared to famer practice. The integrations of micro dose rate of 50% of recommended rate and tied ridges is therefore recommended to small holder’s famers located in semi dry areas of central Tanzania. This will enable farmers to achieve highly agronomic and economic performances compared to farmer practices.en_US
