FIGURE 12.4 Fresh yield of vegetable of each season in the Uluguru Mountains, Tanzania,
from 2004 to 2006 (CV% season 1 = 37.29, season 2 = 28.07, season 3 = 24.44). CCT, control
conservational tillage; CT, conservational tillage; CTG, conservational tillage with in situ
composting; CCT, control traditional tillage; TT, traditional terrace with manure; TTG, tradi-
tional tillage wtih in situ composting. (From Msita H.B. et al. 2010b. Effect of conservational
tillage on soil loss and plant nutrient status on vegetable yield, northern slopes of Uluguru
Mountains, Morogoro, Tanzania. In: Msaky J.J., Kanyama-Phiri G.N., Shongwe G.N. (Eds.),

4.33, CTG = 44.68, and CT = 15.28 Mg/ha) when compared with traditional till-
age, which exhibited a lower yield (CTT = 0.88, TTG = 13.85, and TT = 5.23 Mg/
ha) (Figure  12.4). From this study, it was apparent that all conservation tillage
increased the yield of vegetables in the sloping lands of the Uluguru Mountains,
Tanzania. It can be concluded from this study that conservation tillage for veg-
etable production on sloping land is the best practice that can be promoted for
small-scale vegetable farming on fragile ecosystems.
12.4 CONCLUDING REMARKS
The following concluding remarks are made in the light of gaps revealed from the
discussion in this chapter so as to provide further insights into optimal soil and water
conservation practices based on the principles of CA for enhanced agricultural pro-
duction in East Africa:
