ABSTRACT Fusarium wilt is a plant disease caused by Fusarium udum (Butler). It is a soil and seed borne fungus which causes significant yield losses in susceptible cultivars throughout the pigeonpea growing areas. Numerous control measures have been suggested to alleviate the problem but their success has still remained low due to prohibitive costs. Development of resistant pigeonpea varieties is sought as an alternative for control of the disease. However, the task of developing resistant pi...
ABSTRACT A survey was carried out in three potato growing Districts of the Southern Highland Zone of Tanzania to determine incidence and severity of bacterial wilt of potato caused by Ralstonia solanacearum and characterizing the strains of the causing pathogen. Ten villages from each district and five fields from each village were surveyed. The fields and plants were randomly selected and bacterial wilt symptoms identified. Wilt incidence was recorded based on number of plants showing sympto...
ABSTRACT An experiment was conducted at the Poultry unit of Kizimbani Agriculture Training Institute in Zanzibar to evaluate the effect of seaweed as mineral source in the growth performance of broiler chickens and carcass characteristics. Two hundred and forty (240) broiler chickens were fed four dietary treatments (T1, T2, T3 and T4), containing 0, 1, 1.5 and 2% seaweeds, from 8 - 49 days of age. Feed intake was measured daily while live weight was measured on a weekly basis. After seven we...
