Impact Of Soil Amelioration On Weed Ecology And Control, Catherine Borger, Arslan Peerzada Dr, Gaus Azam Dr

Experimental Summaries - Plant Research

The project focussed on three main findings from the literature review:

1. Weed ecology in response to changes in soil characteristics.
2. Soil movement and weed seed burial following use of varying strategic tillage implements; and
3. Management of weeds in the years directly after amelioration.

The work highlighted that weed growth was either less impacted by changes to soil properties than crop growth, or weed growth and competitive ability were favoured by the same amelioration techniques that favour crop growth. Following amelioration, improved growth of competitive weed species needs to be considered in weed management plans.

Leptospira Serovars Circulating Among Human, Cattle And Goats With Associated Risk Factors In Ngara And Kibondo Districts, North-Western Tanzania, Jestina V. Katandukila, Ackrey G. Sissa, Ginethon G. Mhaphi, Yeremia J. Chuhila, Fred D. Chibwana

Tanzania Journal of Science

Leptospirosis is a neglected zoonotic disease, prominent in north-western Tanzania where interactions among humans, livestock and wildlife is high. This study therefore, assessed Leptospira seroprevalence and associated risk factors by screening Leptospira serovars from blood sera of cattle, goats and humans in Ngara and Kibondo Districts using Microscopic Agglutination Test (MAT). Blood sera were positive for seven Leptospira serovars in which Sokoine, Sejroe and Grippotyhposa had higher seropositivity of ≥ 20.9%, whereas Leptospira serovars Kenya, Pomona, Lora, and Bataviae had seropositivity of < 10%. Variation of seropositivity and seroprevalence between Ngara and Kibondo Districts was insignificant (p = 0.0718) but varied significantly between humans, goats and cattle (p = 0.0183). Leptospira serovars Sejroe and Grippotyphosa were present in humans, goats and cattle. Sokoine, Pomona and Bataviae were co-positive in humans and goats, while serovars Kenya and Lora were co-positive in humans and cattle, indicating the possibility of dualistic transmission of Leptospira serovars in the ecosystem. Suggested risk factors associated with acquiring Leptospira bacteria were drinking contaminated water, feeding contaminated food and farming in contaminated soils. Prevalence of Leptospira in the current study alerts for health and economic risks in north-western Tanzania, which requires intensive education programs on leptospirosis transmission and avoidance.

Tanzania Journal of Science

Although botanical extracts have been widely studied globally, the efficacy of neem and Mexican marigold against cabbage insect pests is scanty. Field experiments were conducted at Kalenga and Mgera in 2022 using a randomized complete block design. Four treatments (neem, Mexican marigold, a mixture of the two extracts and untreated) were replicated three times. In Kalenga, damage levels for treated plots varied significantly from 3.33 to 9.20% and 5.0 to 18.33%, while for untreated plots varied from 37.70 to 45.85% during the rainy and dry seasons, respectively (F(3, 499) = 111.71, p < 0.05). A similar trend was recorded in Mgera, the damage levels varied significantly between treated (4.44–15.83%) and untreated plots (34.40–46.60%) (F(3, 449) = 94.23, p < 0.05). Treated plots had higher marketable cabbage yields (30.6–43.10 t/ha) than untreated plots (4.78–11.20 t/ha), which differed significantly in Kalenga (F (3, 67) = 141.79, p < 0.05) and Mgera (F (3, 67) = 53.36, p < 0.05). These extracts have shown insecticidal properties, can serve as promising candidates for further studies aimed at isolating active compounds for scaling up ecologically friendly strategies of controlling pests and improve the quality of cabbage products.
