Correlation Between Electromagnetic Wave Equation and Einstein Theory of Relativity in Derivation of Schrödinger Equation and Hilbert Space Operators "
(2020-03)Operators in Hilbert space have properties which are useful in the study of mathematical abstract areas such as approximation theory, Banach Fixed point theory, the spectral theory as well as Quantum Mechanics. Schrödinger ... -
Plant Propagation: A Teaching Resource Packet with Emphasis on Agroforestry and Fruit Trees in East Africa
(Cornell University, Ithaca, NewYork, USA, 1992)The products and services provided by trees have always been used in farming. In the past, trees grew naturally on farm lands. The rise in population, and resulting increased demand for wood products, has led to loss of ... -
A protocol for rooting and growing apple rootstock microshoots.
(1998)Microshoots of apple (Malus domestica Borkh.) rootstocks G. 65, G.30 and G.11 were transferred from stage II axillary shoot cultures to stage III rooting media containing 10 levels of indole-butyric acid (IBA) for four ... -
Malus germplasm varies in resistance or tolerance to apple replant pathogens in a mixture of New York orchard soils.
(American Society for Horticultural Science, 2000-04)We tested 40 seedling lots and 17 clonal accessions - representing 941 genotypes and 19 species or interspecific hybrids of Malus - for their resistance or tolerance to apple replant disease (ARD) in a mixture of five New ... -
Effect of time of pruning and lungs on non-structural carbohydrates of tea (Camellia sinensis L.).
(2003-03)An experiment was conducted at Kipkebe Estate, Sotik, Kenya, with the aim of establishing the effects of pruning time and resting period on total non-structural carbohydrate (TNC) reserves, regrowth and yield of tea. In ... -
Effect of pruning time and resting period on total non-structural carbohydrates, regrowth, and yield of tea (Camellia sinensis L.).
(Taylor and Francis, 2015-11-07)An experiment was conducted at Kipkebe Estate, Sotik, Kenya, with the aim of establishing the effects of pruning time and resting period on total non-structural carbohydrate (TNC) reserves, regrowth and yield of tea. In ... -
Rapid micropropagation of passion fruit (Passiflora edulis Sims.) varieties.
(2004-02)Lack of adequate, healthy plants can hamper production of passion fruits (Passiflora edulis Sims.). Seed propagation results in undesirable variability, inadequate and seasonal supply. This research aimed at rapid generation ... -
Current characteristics of cassava mosaic disease in post-epidemic’ areas increase the range of possible management options.
(Association of Applied Biologists, 2006-06-05)As a case study to document the current characteristics of cassava mosaic virus disease (CMD) in postepidemic areas, surveys were carried out, in 2003 and 2004, in Siaya District of western Kenya. This was an area affected ... -
Effects of mulch and cultivar on strawberry productivity under tropical highland conditions.
(2006)A study was conducted to determine effects of four mulches (cut grass, clear polyjilm, black polyjilm, and none) on productivity of four strawberry (Fragaria x ananassa Duch) cultivars (Pajaro, Aiko, Fern and Douglas) under ... -
Effects of integrated nutrient sources on growth and yield of strawberry grown under tropical high altitude conditions.
(Horticultural Association of Kenya, 2008)Strawberries are popular both in fresh and processed forms because of their enormous values. Low soil fertility is among major factors constraining strawberry productivity in Kenya. Consequently, effects of cattle farmyard ... -
Growth of ranunculus cutflower under tropical high altitude conditions.
(Horticultural Association of Kenya, 2009)Cutflower production and marketing is partly challenged by lack of new, exciting and improved varieties to satisfy customer needs of a different flower. Ranunculus (Ranunculus asiaticus L.) is a bulbous plant that originated ... -
Growth of ranunculus cutflower under tropical high altitude conditions. 2: Effects of GA3 and shade on light intensity and temperature modification
(Horticultural Association of Kenya, 2009)Customer needs of a different flower are increasing over time worldwide. Many bulbous plants including ranunculus fit the category of a different flower because they are not known. Ranunculus(Ranunculus ... -
Response of strawberry quality and profitability to farmyard manure and triple super phosphate under tropical high altitude conditions
(2011)Quality of strawberries in the tropics is partly limited by poor soil fertility, while profitability of different nutrient management strategies has not been established. The present study determined the effect of 0, 18, ... -
Effectiveness of phytosanitation in cassava mosaic disease management in a post-epidemic area of western Kenya
(2011-07)The effectiveness of phytosanitation in managing cassava mosaic disease (CMD) was studied in a post-epidemic area of western Kenya. Four varieties [MM96/4466 (resistant), TMS 30572 (Migyera, moderately resistant), Bukalasa ... -
Irrigation rate and mulch type significantly affect growth and flowering of purple passion fruit (Passiflora edulis f. edulis Sims).
(2011)Purple passion fruit (Passiflora edulis f. edulis Sims.) is an important fruit in the tropics, but its growth can be adversely affected by drought stress. This study evaluated effects of irrigation rate and mulch type on ... -
Irrigation and mulch significantly enhance yield but not quality of purple passion fruits
(2011)Purple passion fruit (Passiflora edulis f. edulis Sims.) is an important fruit in the juice industry but its yields can drastically decline under drought stress. The present study evaluated the effects of irrigation and ... -
Irrigation rate and mulch type significantly affect some physiological processes of purple passion fruit (Passiflora edulis f. edulis Sims.) under drought stress.
(2011-12)Purple passion fruit (Passiflora edulis f. edulis Sims.) is an important fruit in the tropics, but its growth can be adversely affected by drought stress. This study evaluated effects of irrigation rate and mulch type on ... -
Climate change adaptation of potato (Solanum tuberosum L.) 2: Influence of Biozyme® rate on potato growth and development.
(2013-07-31)Potato is an important food crop worldwide. Growers adopt potato production due its short growing season and poor soils tolerance. They use agrochemicals to improve growth under unreliable rainfall. Biozyme® foliar feed ... -
Climate change adaptation of potato (Solanum tuberosum L.): Influence of Biozyme® rate on potato yield, quality and mineral nutrient uptake
(2013-07)Potato (Solanum tuberosum L.) is an important food crop worldwide. Growers prefer potato because of its short growing season and tolerance to poor soils. Growers are using different agrochemicals so as to improve tuber ... -
