Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015) Musyimi, D.M.; Okelo, L.O.; Okello, Victor Samuel; Sikuku, P.S.
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 (Samuel et al., 2005; Imeokpara and Okusanya, 1994; Ayeni et al., 1997). Allelopathy is the inhibitory or stimulatory effect of a plant on another by chemicals released from the donor plant to the environment (Taiwo and Makinde, 2005; Bano et al., 2012). Allelopathy is a process by which plants release chemical compounds in their vicinity (Rice, 1984). Studies have shown that different plant parts release toxic metabolites into the soil that affect adversely germination and growth of plants (Kumar et al., 2008).
Responses of slenderleaf rattlebox (crotalaria ochroleuca) to water deficit
(2017) Sikuku, P.A.; Musyimi, D.M.; Kariuki, S.; Okello, Victor Samuel
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 mainly causes reduction in plant growth and development. Crotalaria ochroleuca is an important indigenous leafy vegetable which is a legume grown and consumed in Kenya and Tanzania and other parts of Africa. The slender leaf rattlebox is very rich in protein, calcium, iron, Beta carotene and ascorbic acid and therefore can contribute to good human health therefore increased production of this vegetable should be used to solve the problem of malnutrition in the country and also act as food security. A study was conducted to evaluate the responses of slender leaf rattlebox to Water deficit.
