“…Similarly, allelopathy of some legumes such as black gram (Vigna mungo) [28], mung bean (Vigna radiate) etc. have also been reported [29]. Allelopathy has been used to manage weeds and is considered as natural herbicides that are safer to the environment compared to synthetic herbicides [30].…”

Cereal rye (Secale cereale L.) is widely used as cover crop because of its allelopathic effects and effectiveness in weed suppression. In the Southeastern US, rye is traditionally grown for winter grazing in dormant bermudagrass pastures, where alfalfa (Medicago sativa L.) is increasingly planted as a companion crop. The effect of cereal rye on alfalfa as a succeeding crop is not known. Therefore, the objective of this study was to evaluate the effect of cereal rye on alfalfa seedling emergence, growth, forage yield, and weed suppression in field conditions. Rye was planted in the fall (mid-October) and the biomass was harvested in spring (March) followed by disking and incorporation of the remaining stubble in the soil. Alfalfa seed was planted four weeks later. The experiment design was a split-plot design with the main plots being no-rye and after-rye and the sub-plots being alfalfa cultivars. Ten alfalfa cultivars were planted in three replications after-rye and three replications with no-rye as a previous crop. In the establishment year, weed density was significantly (p < 0.01) lower in the after-rye alfalfa plots by nearly 77%. Alfalfa seedling counts were also significantly lower (p < 0.01) among the cultivars planted in the after-rye block compared to the no-rye, with a seedling count reduction between 35% and 64%. Reduction in total dry biomass yield varied from 15% to 43% among the cultivars planted in the after-rye block. The results of this study also suggest that the allelopathic effect of rye on alfalfa may not persist beyond the establishment season, but the enormous yield reduction in the first production season may constitute a costly economic penalty in terms of forage production. There was variation in the response of different alfalfa cultivars to the effect of rye residue as indicated by the variation in the magnitude of reduction in stand count and forage yield. This warrants more research in multi-location trials with and without rye in order to establish whether there is genetic variation in alfalfa germplasm in their tolerance to cereal rye allelopathy.

“…These bioactive chemicals are often referred to as allelochemicals because they communicate with the surrounding environment (Mondal, Asaduzzaman, & Asao, 2015). Allelopathy is a mechanism in which chemicals produced by plants and released into the environment, which may increase or decrease the associated plant growth.…”

The Mediterranean region is a rich source of bioactive phytochemicals contained in plants and the secret of longevity. Mediterranean region represents an intangible cultural heritage of humanity and it is partially still based upon many wild plants. The use of wild plants possibly emerged in the Neolithic period in the Fertile Crescent and migrated westwards through the Mediterranean area. The genus of Prangos has 30 species distributed from the Mediterranean to central Asia, 14 of them are found in Turkey while 7 of them are found in the different areas of the Kurdistan region of Iraq. Prangos platychlaena Boiss. (family: Apiaceae) abundantly found in the mountains of Halgurd. P. platychlaena has been reported as potent antioxidant plant, and traditionally used as carminative, and diuretic. Prangos also traditionally used in the treatment of burning and wounds, kidney, and urinary disorders. P. platychlaena have been reported to cause toxicological effects in animals, and shows potential cytotoxic activities in invitro studies. The current review has covered comprehensively habitats, ethnopharmacology, phytochemistry, toxicological and pharmacological actions of P. platychlaena.

“…Perennial crops and monocultures of these families are common in many parts of the world, and they cause a number of problems due to soil sickness, regeneration failure and replant problems. Allelochemicals from legumes are mainly polyphenols and propanoids [41]. Crops from the family Brassicaceae contain compounds called glucosinolates, which break down during the decomposition of post-harvest residues into powerful volatile allelochemicals-isothiocyanates, which can affect plant growth and microbial activity [42][43][44].…”

Soil Contamination - Current Consequences and Further Solutions

View full text Add to dashboard Cite

Contamination of the soil environment mostly is identified with industry, especially mining and road transport. Unfortunately, also in the commercial horticulture, there are numerous problems concerning the contamination of soils and substrates. Sources of contamination can be fertilizers and waste materials polluted by heavy metals, particularly by cadmium. In the greenhouses where traditional methods of cultivation are used, the soil pollution due to the application of excessively high doses of fertilizers constitutes an environmental hazard. Much faster similar effect occurs in greenhouses where an open system of fertigation is used. In addition to mineral impurities, organic compounds emitted by the plant or that are formed during decomposition of organic matter are the problem. This phenomenon is called allelopathy. In practice, it concerns the monoculture and perennial crops and especially is observed in nurseries, orchards, plantations of berries and asparagus. For this reason, in the later section, the soil sickness, replantation problem and toxicity of mulches in green areas are also discussed.
