Abstract

Seromonitoring for antibodies against especially dangerous viral infections in small ruminants in the Republic of Tajikistan was conducted. Antibodies to sheep pox and PPR viruses were detected in blood sera of small ruminants.

Key words: Virus, antigen, enzyme-linked immunosorbent assay, sheep pox, peste des petits ruminants.

Abstract

Conventional research approaches have lost considerable momentum after their astonishing achieve-ments during the green revolution. The negative side of focusing rigorously on production improve-ment was eminent around 1980 and led to considerations of environmental, gender and equity aspects - making agricultural development much more complex than previously. In the search for new ways of addressing the persisting problems of food insecurity and malnutrition, new ways should be explored. Based on the experiences from three international, African research projects, the article argues the case of participatory action research and cross-disciplinarity as some of the key elements in future animal science research in developing countries. The benefits are outlined as well as the challenges for the researchers and the donor agencies.

Key words: Action research, agriculture, agro-forestry, animal science, cross-disciplinarity, developing countries, livestock systems, paradigms, participation, poverty.

Abstract

While isolating sheep pox virus from samples of air, water, hay and grain experimentally infected with this agent various filters and eluting media were tested. Possible usage of enzyme-linked immunosor-bent assay (ELISA) for specific indication of the sheep pox virus in various objects of veterinary super-vision was investigated.

Key words: Specific indication, objects of veterinary supervision, concentration, elution, virus, antigen, en-zyme-linked immunosorbent assay.

Abstract

Advantages of cowpea were tested in terms of net N-input by cowpea mono- or intercropped with maize in a crop sequence where sparingly soluble P sources were added to the first year crop. The grain yield of maize grown after cowpea monocrop was doubled and the N uptake increased by 60% compared to maize following maize. The N-value of growing cowpea monocropped prior to maize monocrop was equivalent to the application of 50 kg N ha^-1 as mineral fertiliser. When maize followed a maize-cowpea intercrop, grain yield was increased by 67%. Around 34% of the N contained in cowpea residues was recovered in the following maize as estimated by ¹⁵N. There was however no benefit on the second season maize of applying sparingly soluble P sources to the first season legume.

Key words: Cowpea, crop sequences, maize, nitrogen budgets, sparingly soluble phosphorus.

Abstract

The effect of moisture stress on the physical and histochemical properties of three certified improved varieties of Kenaf (Hibiscus cannabinus L.) relevant to pulp and paper production were investigated. The test plants were grown in the field on a deep sandy-loam soil in the Botanical Garden of Abia State University, Uturu. Three watering regimes representing well-watered control, moderate stress and severe water stress were imposed on the plants. Each irrigation regime was replicated three times in a split plot design with watering treatments as the main plots and the varieties as the sub-plots. Water deficit did not adversely affect the fibre dimensional properties as well as the fibre derived values. Analysis of histochemical properties of Kenaf indicated that water deficit enhanced these properties in the stressed plants when compared with well-watered plants. Thus suggesting that water stress enhances the quality of pulp and paper produced from Kenaf.

Key words: Hibiscus cannabinus, kenaf, histochemical, pulp, paper, water deficit.
