Growth changes of seven Amaranthus (spp) during the vegetative and reproductive stages of development as influenced by variations in soil water deficit
(2015)
Soil water deficit is a principal a biotic factor that limits plant growth and
development in dry areas. Insufficient moisture contributes to soil water deficit and some
negative effects on Amaranthus (spp) such as ...
A situational analysis of agricultural production and marketing, and natural resources management systems in West Kenya
(ILRI, 2015-10-30)
The Western and Nyanza provinces that make up the West Kenya Humidtropics action site
form part of the 20% arable land in Kenya. The region is characterized by high agricultural
potential coupled with high population ...
Generation Means Analysis for Estimation of Genetic Parameters for Striga hermonthica Resistance in Maize (Zea mays L.)
(Canadian Center of Science and Education, 2015-08-01)
Striga hermonthica is a parasitic weed species that causes considerable yield loss in susceptible maize cultivars
in western Kenya. A generation means analysis was conducted to estimate gene effects influencing
resista ...
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)
Invasive plant species when introduced into new environments may result into a number of
ecological problems (Howard et al., 2000). They may influence other species through
pathways such as allelopathy or phytotoxicity ...
Chlorophyll fluorescence parameters and photosynthetic pigments of four Glycine max varieties under Aluminium chloride stress
(2015)
Soy bean (Glycine max L.) is a commonly grown legume crop in Kenya. Soy bean grains are
among the world's most important in terms of protein content of 35-40% and oil content of 15-
22%. Soy bean grains are also rich ...
Ecology and Physiology of Plant growth in relation to soil salinity
(2015)
This work is intended as a review of soil salinity as one common abiotic stress in ecological
systems that adversely affect plant growth. In arid and semi arid areas, saline areas or areas
irrigated with saline waters, ...
Evaluation of different improved upland rice varieties for low soil nitrogen adaptability
(2015)
Scarcity of nitrogen fertilizer is a major constraint to rice production particularly
in developing countries. Low soil fertility prevalent in farmer's fields has led to low rice yields
and the ever escalating fertilizer ...
