The potential of replacing conventional dairy supplements with forage legume-based diets in Zimbabwe’s smallholder dairy sector por Gwiriri, Lovemore C., Manyawu, Godfrey J., Mashanda, P.B., Chakoma, Irenie, Moyo, Siboniso, Chakoma, C., Sethaunyane, H., Imbayarwo-Chikosi, V.E., Dube, Sikhalazo, Maasdorp, B.V.

“…Milk protein, total solids and lactose content of cows fed commercial supplements was significantly (p < 0.05) higher than those fed forage legume-based supplements, although protein content was similar to cows fed lablab-based supplements. Dietary gross margins were higher for cows fed velvet bean and lablab-based supplements by 17% and 16.5%, respectively. …”

Whole genome sequencing of a banana wild relative Musa itinerans provides insights into lineage-specific diversification of the Musa genus por Wu, W., Yang, Y.L., He, W.M., Rouard, M., Li, W.M., Xu, M., Roux, N., Ge, X.J.

“…These include a transition from wood to herbaceous in the ancestral Musaceae, intensification of cold and drought tolerances, and reduced diseases resistance genes for subtropical marginally distributed Musa species. Prevalent purifying selection and transposed duplications were found to facilitate the diversification of NBS-encoding gene families for two Musa species. …”

A pilot study of Leptospira in rodents in North-Eastern Kenya por Kimari, M.W.

“…These results demonstrate the need for policy makers to consider disease emergence and transmission in these marginalized parts of Kenya. More epidemiological knowledge of the disease like circulating serotypes and role of animal hosts in the area will greatly aid in forming public health policy aimed at controlling the disease.…”

Adoption and impact of tissue culture bananas in Burundi: an application of a propensity score matching approach por Ouma, Emily A., Dubois, T., Kabunga, N., Nkurunziza, S., Qaim, M., Asten, Piet J.A. van

“…To improve the productivity of banana (Musa spp), access by farmers to improved pest- and diseasefree planting material is fundamentaL Traditional methods of propagating bananas using suckers serve to perpetuate the problem of pests and diseases, thereby reducing production even further, Banana plantlets obtained from tissue culture (TC) technology are potentially disease-free alternatives but remain largely inaccessible to most smallholder farmers due to the high cost of plantlets, This study employs a propensity score matching technique to examine the adoption and impact of TC banana technology in Burundi using a sample of 313 banana-farming households, In Burundi, TC bananas are subsidized by FAO and non-government organizations (NGOs), thus providing free plantlets to farmers, However, the adoption of TC bananas has not resulted in any significant increment in banana productivity or gross margins compared with traditional propagation using suckers, Improvements in institutional factors related to the delivery of technology and improvement of TC plantlet quality seem to be preconditions for more favourable technology impacts.…”

Water and sand: is groundwater-based farming in Jordan's desert sustainable? por Naber, M.A., Molle, Francois

“…This paper is based on field work in two locations of Azraq groundwater basin [around the Azraq oasis and in the northern part (Mafraq)], and first presents farm typologies which show the variability of farm gross margins and the contrast between the two zones. While Mafraq stands for capital-intensive fruit-tree cultivation on legal land/wells, Azraq's agriculture is largely based on olive cultivation and wells that are either illegal or granted permits with higher block tariffs, and has a return that is only one tenth of Mafraq's. …”
