Evaluation of relative competitive ability and fitness of sorghum bicolor×sorghum halepense and sorghum bicolor×Sorghum sudanense F1 hybrids
(2015)
Introgression of crop alleles in weedy sorghum populations may have an additive
effect on the adaptive character of the weeds making them more competitive. The
relative fitness in the F1 generation derived from weedy and ...
Improving potato tuber yields using genotypes with multiple virus resistance in Kenya
(2013)
Potato (Solanumtuberosum L.) viruses play a major role in lowering yields and quality of ware
and seed tubers in Kenya. This experiment was conducted to determine potential of potato clones
with multiple virus resistance ...

(2015-07-31)
Two field experiments were carried out concurrently at the Faculty of Agriculture, Field station farm, University of Nairobi in March-July 2000 (season I) and June-September 2000 (season II) to determine the effect of ...
Post-harvest practices, constraints and opportunities along cassava value chain in Kenya
(Online, 2016-08-27)
marketing despite its great potential as a food, feed and for industrial application, its processing and remains economically unexploited. A cross-sectional baseline survey was undertaken in Western (Migori and Busia) and ...
Sensory attributes of coffee under different shade regimes and levels of management
(2015)
Despite coffee bean physical and beverage quality attributes being inherent factors, the environment, which
includes crop management factors, can play a major role in determining their expression. This study was
conducted ...
Effects of early and late harvest on agronomic performance and stability of late blight resistant (R-gene Free) Potato genotypes
(Korean Society of Crop Science and Springer., 2014-06-01)
Late blight is an important constraint to potato production and genotype resistance is an effective disease control mesure. Ten late
blight resistant potato genotypes (R-gene free) were assessed for yield performance and ...
Efficacy of 1–methylcyclopropene in purple passion fruit (Passiflora edulis Sims) as affected by dosage and maturity stage
(2015-04-13)
The study was conducted to determine the efficacy of two 1–MCP application regimes (2 ppm for 24 hours and 4 ppm for 12 hours) to extend the shelf life of passion fruits. The fruits were harvested at two stages of maturity ...
Botanical composition and selective feeding by goats in the semi-arid Lands of central-eastern Kenya
(2013)
Botanical composition of University of Nairobi’s Machang’a Field Station, Mbeere, in the Semi-arid Central-Eastern
rangelands of Kenya was inventoried by reconnaissance survey. Relative abundance of the various plant ...
Effect of packaging material on shelf Life and quality of ware potato tubers stored at ambient tropical temperatures
(Springer Netherlands, 2018-09-01)
The effect of seven packaging materials (transparent perforated and non-perforated high-density polyethylene (HDPE) bags, black perforated and non-perforated low-density polyethylene (LDPE) bags, nylon gunny sacks, khaki ...
Growth and nutrient content of cowpea (Vigna unguiculata L.) in acidic soils of south western Kenya
(2018-11-10)
Field experiments were carried out in Kericho East (0°22' S, 35°17' E) and Bomet central (0°47' S, 35°21' E) to determine the effects of liming and phosphorous (P) fertiliser on nodulation, growth, yield and nutrient content ...
