To address technology impact at the household level, farms were selected in two broad agro-ecological zones, Kampala and Highland. The Kampala zone was delineated as a “new” region with a substantial milkshed that was not delineated with the Kenya agro-ecological extrapolation. Since the “Horticultural” zone and Kenya dominated the landscape where dairying occurred outside of the Kampala milksh...

Serum progesterone and estradiol-17β levels were estimated in Nili Ravi buffaloes (n=190) with and without fetal membranes retention in three agro-ecological zones of Punjab. The results showed that serum progesterone concentration was significantly higher (P<0.05) in buffaloes with retention of fetal membranes (RFM) compared to buffaloes without retention of fetal membranes (NRFM). The compari...

one of the effective tools for identifying land resources and assign them to the best and most profitable forms of land productivity, susceptibility of agro-ecological zoning . in this study agro-ecological zoning of satellite imagery and gis were used. after agro-climatic zoning (based on isorain, isothermal and length of growing period maps) and agro-edaphic zoning (based on soil, slope and l...

Under conditions of high vapor pressure deficit (VPD) and soil drying, restricting transpiration is an important avenue to gain efficiency in water use. The question we raise in this article is whether breeding for agro-ecological environments that differ for the rainfall have selected for traits that control plant water use. These are measured in pearl millet materials bred for zones varying i...

INTRODUCTION Food availability and access are strongly affected by seasonality in Ethiopia. However, there are little data on seasonal variation in Infant and Young Child Feeding (IYCF) practices and malnutrition among 6-23 months old children in different agro-ecological zones of rural Ethiopia. METHODS Socio-demographic, anthropometry and IYCF indicators were assessed in post- and pre-harve...

Mineral composition of dry Tamarindus indica LINN pulp and seeds was evaluated on samples collected from three different agro-ecological zones of Uganda (Lake Victoria Crescent, and Eastern and West Nile). The objective of the study was to evaluate the mineral composition of T. indica pulp and seed samples from across Uganda's different agro-ecological zones and land use types. Separately groun...

Maize samples were collected during a survey in three agro-ecological zones in Nigeria to determine the distribution and aflatoxin-producing potential of members of Aspergillus section Flavi. The three agro-ecological zones were, Derived Savannah (DS) and Southern Guinea Savannah (SGS) in the humid south and North Guinea Savannah (NGS) in the drier north. Across agro-ecological zones, Aspergill...
