Item Economic benefits of maize and legumes (common bean and dolichos lablab) intercrop as influenced by rhizobial inoculation(Asian Research Publishing Network) Massawe, Prosper I.; Mtei, Kelvin M.; Munishi, Linus K.; Ndakidemi, Patrick A.Item Effects of dry season supplementation of Calliandra calothyrsus leaf-meal mixed with maize-bran on dairy cattle milk productivity in the West Usambara Highlands, Tanzania(Research Square) Maleko, David Dawson; Msalya, George M.; Mtei, Kelvin M.Item Effects of dry season supplementation of Calliandra calothyrsus leaf-meal mixed with maize-bran on dairy cattle milk productivity in the West Usambara Highlands, Tanzania(Research Square, 2022-06) Maleko, David Dawson; Msalya, George M.; Mtei, Kelvin M.The dry seasons decline in milk production due to insufficient feed supply to dairy cattle poses a great challenge to sustainability of smallholder dairy production systems in Tanzania. Locally produced leguminous fodder tree leaf meals combined with maize bran provide a great potential for overcoming the dry season protein-energy deficit in the basal roughage feeds. This study evaluated the effects of dry season Calliandra calothyrsus (Calliandra) leaf-meal: maize-bran based protein-energy homemade supplementary ration (HSR) on milk production of lactating cross-bred dairy cows in the Western Usambara Highlands (WUHs), Tanzania. Complete randomized design was employed whereby four groups of 4 lactating dairy cows were subjected to four levels of HSR rationed at 0, 2, 4 and 6 kg/cow/day. The lactating cows which were not subjected to HSR supplementation (0 kg/cow/day) were left under farmers’ feeding practices as a control. HSR had significant effect on dry season milk yields (P < 0.001) whereby milk yields were 2.7, 4.5, 5.6 and 6.1 litres/cow/day for 0, 2, 4 and 6 kg HSR/cow/day, respectively. In addition, simulated year-round daily milk yields indicated that 4 and 6 kg HSR/cow/day would double the milk yields. Nevertheless, there was overall significant difference in the income to cost ratios (P = 0.02) whereby it was 0.50, 0.79, 1.06 and 1.09 for 0, 2, 4 and 6 kg HSR/cow/day, respectively. However, the income to cost ratios for 4 and 6 kg HSR/cow/day did not differ significantly (P < 0.05). In conclusion, if the dairy farmers in WUHs are to produce profitable milk amounts during the dry seasons the supplementation level of 4 kg HSR/cow/day to the basal diets is recommended.Item Effects of Rhizobium inoculation and cropping systems involving common bean and lablab on water use efficiency, weeds and insects pests’ infestation(Journal of Biodiversity and Environmental Sciences) Massawe, Prosper I.; Mtei, Kelvin M.; Munishi, Linus K.; Ndakidemi, Patrick A.Item Effects of Rhizobium inoculation and cropping systems on macronutrients uptake and partitioning in two legumes (Common bean and Lablab)(Agricultural Research Communication Centre) Massawe, Prosper I.; Mtei, Kelvin M.; Munishi, Linus K.; Ndakidemi, Patrick A.Item Existing practices for soil fertility management through cereals-legume intercropping systems(World Research Journal of Agricultural Sciences) Massawe, Prosper I.; Mtei, Kelvin M.; Munishi, Linus K.; Ndakidemi, Patrick A.Item The Potential of Using Indigenous Pesticidal Plants for Insect Pest Control to Small Scale Farmers in Africa(Scientific Research Publishing Inc.)
