Wheat’s production chain is one of the sectors that have received a lot of attention not only by the Mozambican government, but also by its national and international partners alike. This is due to the interest of the government and its partners to raise production levels and as such, lower the need of importing these goods in the coming years. Due to efforts from Mozambican government to elevate production levels... Read more.

Cowpea is a major food legume crop in the Sahel with tolerance to drought and to the nutrients-leached acid sandy soils of this region. However, the existing cowpea varieties grown by farmers are low yielding and pest sensitive which make them unsuitable to satisfy farmer’s needs. The objective of this study was to identify high-yielding cowpea varieties which are well adapted to the Sahelian ecosystem. Eight... Read more.

The objective of this study was to evaluate Cynodon species ‘Tifton 85’ at different hay production phases (harvest, baling, and storage) and different (N) rates. Dehydration of the first crop was carried out in the field, while the second crop was in the shed. Dry matter and protein content increased linearly with the N rates. Dehydration in the shed was not effective for hay production, since dry matter... Read more.

Ethanol production from sweet sorghum depends on the quality of the biomass and sugars in the juice extracted from the plant. However, quality may be compromised by Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) or sugarcane borer infestation. This study evaluated the effects of infestation by the pest on sweet sorghum juice productivity and quality. Sorghum variety BRS506 was planted in an experimental area... Read more.

Fusarium wilt of oil palm is caused by Fusarium oxysporum f. sp. elaeidis (Foe) and is particularly prevalent in Africa. This work shows prospect in the industrial and village oil palm plantations in the Southern region of Ivory Coast, used to assess the incidence and distribution of this disease. The method used entailed taking an inventory of all the plants in a given plot, noting the presence or absence of symptoms... Read more.

Potato soft rot is one of the major destructive diseases affecting potato plants throughout the world. In a survey of different potato growing seasons in different regions of Jordan, samples of rotten potato tubers were collected and 131 isolates identified biochemically as Pectobacterium carotovorum subsp. carotovorum (Pcc). The PCR primer pair (EXPCCR/EXPCCF) was used to detect these Jordanian isolates. The primer set... Read more.
