Chlorophyll fluorescence, protein and chlorophyll content of three nerica rainfed rice varieties under varying irrigation regimes
(2010)Water deficit affects growth and development of rainfed rice leading to a considerable yield reduction or crop failure. Although the rice crop is susceptible to water deficit, there is a marked genotypic variation in protein ... -
Effects of water deficit on physiology and morphology of three varieties of NERICA rainfed rice (Oryza sativa L.)
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Effects of water deficit on days to maturity and yield of three NERICA rainfed rice varieties
(2010-05)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Physiological and biochemical responses of five nerica rice varieties (Oryza sativa L.) to water deficit at vegetative and reproductive stage
(2012)Food shortage is a major problem in sub Saharan Africa as population increases. Over 89% of Kenyans are food poor and are malnourished especially in rural areas. NERICA (New Rice for Africa) are high yielding rainfed rice ... -
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(PSCI Publications, 2015)Allelopathy is a common among plants. Allelopathic substances affect seed germination, plant growth and development or even affect chlorophyll synthesis by the plant leaves. Tithonia diversifolia contains allelochemicals that ... -
Evaluation of different improved upland rice varieties for low soil nitrogen adaptability
(IJPSS, 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 ... -
Chlorophyll fluorescence parameters and photosynthetic pigments of four Glycine max varieties under Aluminium chloride stress
(PSCI Publications, 2015)Soil acidity limits agricultural production globally. Different kinds of stresses, mainly Al stress, generated from acid soils affect plant growth and result in food shortage and production. General effects of Al toxicity ... -
Influence of nitrogen supply on photosynthesis, chlorophyll content and yield of improved rice varieties under upland conditions in Western Kenya
(sciencedomain., 2016-07-09)Rice (Oryza sativa) is a principal staple food crop in Kenya. However, its production is still low due to inherently low and declining soil fertility. This has resulted into food and nutritional insecurity and low living ... -
Responses of slenderleaf rattlebox (Crotalaria ochroleuca) to water deficit
(2017)Water deficit affects plant growth and development thus affecting crop productivity. It is the major a biotic stress experienced in the vast semi arid and arid regions of Kenya and the world as a whole. Water deficit ... -
Understanding yields in alley cropping maize (Zea Mays L.) and Cassia siamea Lam. under semi-arid conditions in Machakos, Eastern Kenya
(IOS Press, 2001-01-01)Six seasons of experiments in Machakos, Kenya, revealed that above about 150 mm of rainfall, maize yields per row in alley cropped "replacement" agroforestry (AF) plots, of Cassia siamea Lam. and maize (Zea mays, cv. ... -
Effects of salinity on growth and photosynthesis of avocado seedlings

Growth of avocado plants under saline conditions
(Taylor & Francis Group, 2007-12-13)Avocado (Persea americana Mill.) is an important multipurpose tree crop. A study was conducted to investigate the growth and gas exchange characteristics of avocado seedlings growing under different salinity levels. Plants ... -
Growth performance of bamboo in tobacco-growing regions in South Nyanza, Kenya
(Academic Journals, 2008)The study was carried out on 120 field experimentation sites where 2420 bamboo cuttings were planted under the same natural tobacco growing conditions in five different zones (that is, zone A = hillside/steep sloping ... -
Potential of bamboo as an alternative crop and livelihood strategy to smallholder tobacco farmers in South Nyanza region, Kenya
(Maseno University, Kenya School of Environment and Earth Sciences, Maseno, KENYA, 2009)he presentation reviews successful crop diversification of 120 farm trial sites in Kenya, where bamboo seedlings were planted under the same growing conditions as tobacco crops in terms of soil, altitude, rainfall and ... -
Growth and nutrient uptake among three wetland plant species occurring in Lake Victoria basin in Kenya.
(AGRICULTURE AND BIOLOGY JOURNAL OF NORTH AMERICA, 2010)Nutrient enrichment is one of the most serious threats to wetland ecosystems. Information is lacking, particularly concerning the response of wetland plants species in Kenya in regard to nutrient enrichment of wetlands. ... -
Effect of water deficit on the physiological and morphological characteristics of Mango (Mangifera indica) rootstock seedlings.
(Academic Journals, 2010)Six month old Mango (Mangifera indica L.) rootstock seedlings were grown in 20 L plastic pots in a greenhouse at Maseno University, Kenya, to investigate the effect of water deficit on its morphological and physiological ... -
Potential of corporate social responsibility for poverty alleviation among contract sugarcane farmers in the Nzoia Sugarbelt, Western Kenya
(Springer Netherlands, 2009-10-01)Although contract sugarcane farming is the most dominant and popular land use among farmers in Nzoia Sugarbelt, results from a 2007 study suggests that the intended goal of increasing farmers’ incomes seems to have failed. ... -
Ecophysiological and genetic characteristics of three wetland plant species occurring in lake Victoria region in Kenya.
(Asian Research Publishing Network-ARPN, 2010)This study was carried out to investigate the ecophysiological and genetic characteristics of some selected wetland plant species in Lake Victoria basin, Kenya. Seedlings of Cyperas esculentus L., Aframomum angustifolium ... -
Agrobiodiversity endangered by sugarcane farming in Mumias and Nzoia Sugarbelts of Western Kenya
(2010)Commercial sugarcane farming has been practised in western Kenya for nearly forty years. This monocultural land use is associated with loss of natural vegetation and cropland, thus undermining food security status of a ... -
Effects of sugarcane farming on diversity of vegetable crops in Mumias Division, Western Kenya
(Academic Journals, 2012-10-31)Sugarcane farming is a commercial monocultural land use practice which often lead to reduction in agrobiodiversity. The study was carried out in Mumias Division of Western Kenya where 68% of the land is under commercial ...
