F.Item Knowledge Sharing and Communication Tools for Dialogue Issues on Productivity of Water in Agriculture in Mkoji Sub-catchment, Tanzania(Sokoine University of Agriculture, 2003) Kasele, S. S.; Mlozi, M. R. S.; Hatibu, N.; Mahoo, H. F.The concept of productivity of water in agriculture is new and is understood differently by different stakeholders. Yet to apply it, all stakeholders require a common understanding. Currently there is limited understanding of how the concept can be communicated to different stakeholders. This limits the potential for dialogue to enable concerns to be resolved. This study investigated knowledge-sharing and communication tools suitable in facilitating dialogue among different stakeholders on the productivity of water in agriculture in Mkoji sub-catchment in the upper part of the Rufiji Basin, Tanzania. The study was based on a survey of multiple stakeholders of water in the study area, including direct water users in agriculture, namely farmers; water resources and agricultural experts; and water managers, especially in irrigated systems. A high proportion (87.5%) of the smallholder farmers indicated low awareness of the concept as universally defined. The experts were aware of the basic definition of productivity of water in agriculture as the ratio of total crop yield to the volume of water used. Given past experience in the study areas, knowledge sharing through farmer training, demonstration plots, field visits, radio and posters will assist in increasing the understanding of different stakeholders and thus improve dialogue.Item Land characteristics, run-off and potential for rainwater harvesting in semi-arid areas of TanzaniaRwehumbiza, F.B.R.; Hatibu, N.; Machibya, M.Item Paths of influence among components of yield in sorghum (Sorghum bicolor (L) Moench, cv Tegemeo) grown in the semi arid area of Dodoma Region, TanzaniaReuben, S.O.W.; Rwehumblza, F.B.R.; Mahoo, H.F.; Hatibu, N.; Makungu, P.; Ashimogo, G.C.Item Paths of influence among components of yield in sorghum (Sorghum bicolor (L) Moench, cv Tegemeo) grown in the semi arid area of Dodoma Region, Tanzania(1998) Reuben, S.O.W.; Rwehumblza, F.B.R.; Mahoo, H.F.; Hatibu, N.; Makungu, P.; Ashimogo, G.C.Sorghum is a food security crop in tropical marginal areas. Improvement strategies for yield under such conditions are important. Genetic improvement for yield is done thr0ll:gh improvement of its components. Due to yield component compensation, this improvement strategy is made less rewarding. It is therefore important to know compe1J.satory mechanisms existing for better improvement strategies. Studies on the nature of component compensations in sorghum are limited and virtually lacking under Tanzanian conditions. A field experiment was conducted to investigate the nature of interrelationships among components of yield in sorghum at the experimental plots of Hombolo Research Station in the semi-arid zone of Dodoma Region, Tanzania. Six treatment combinations, of rain water harvesting techniques and fertilizer were laid out in a randomized comple,te block design (ReED) with four replications during the growing season of 1996/97. Number of grains was an important component which was significantly correlated (r=O. 982***) with grain yield and had a high positive direct effect (0.979) on yield. Average grain weight was not import~nt in influencing yield of sorghum. Plant biomass had a negative direct effect (-1.2997) on average grain weight but was not important in influencing number of grains. Plant height and percent light intercepted directly influenced number of grains and average grain weight negatively. The negative influence (- 0.8712) of plant height on number of grains was compensated to a low relationship (r= -0.337) mainly by its positive indirect influence (0.3780) through light interception. Improvement strategies should aim at shorter plants with more grains, of lesser canopy development and biomass in these semi arid areas.Item Performance of maize under micro-catchment rainwater. harvesting in western Pare lowlands and Morogoro, TanzaniaHatibu, N.; Gowing, l.W.; Mzirai, O.B.; Mahoo, H.P.Item Performance of maize under micro-catchment rainwater. harvesting in western Pare lowlands and Morogoro, Tanzania(1999) Hatibu, N.; Gowing, l.W.; Mzirai, O.B.; Mahoo, H.P.Micro-catchment Rainwater Harv.esting. (RWH) has been defined as a method of collecting run-off from a Catchment Area (CA) over short distances not exceeding 100 m and supplying it to an adjacent Cultivated Basin (CB). It is a system that is designed to concentrate rainwater so as to utilize it more effe"ctively in areas- where. the seasonal. rainfall amounts are frequently lower than crop water requirements. The Catchment to Basin Area Ratio (CBAR) is an important parameter in the design of micro-catchment systems. It usually varies between 1:1 and 10:1. However, methodsfor deciding the optimumle·ve! of CBAR for differef!t farming systems are not available. The purpose of the experiments reported here was to evaluate the CBARfor maize production in semiarid areas of Tanzania. The experiments were run between 1992 and 1995. in semi-arid areas of Morogoro and Mwanga Districts of Tanzania, to assess the peiformance of maize grown in microcatchment systems with CBAR varying from 0:1 to 4:1. Maize var. TMVI was grown in Mwanga District while maize-var. Staha was used as a test crop in Morogoro District. Grain was harvested in five out of six experimental seasons in Mwanga (Masika 1993, 1994 and 1995 and Vuli 199411995 and 199511996). In Morogoro, grain harvest was obtained only in two seasons (Masika 1993 and 1994) out offour. The results showed that micro-catchment RWH farming is feasible during Vuli. The yield benefits due to RWH were found to be 120 - 152· % and significant at P = 0.05. The benefits during Masika were found to be very low at only 12 - 17 % and not significant at P = 0.05.Item Review of rainwater harvesting techniques and evidence for their use in semi-arid TanzaniaGowing, J.W.; Mahoo, H.F.; Mzirai, O.B.; Hatibu, N.Item Technical Note on Performance of Macro-Catchment Rainwater Harvesting for Maize Production: Preliminary ResultsKajiru, G.J.; Hatibu, N.; Bakari, A.M.; Kishebuka, S.
