“…On the other hand, sunflower extract was activated growth of shoot V. faba values (11.86 cm) while peanut extract was activated growth of shoot B. vulgaris values (13.58 cm). These results are in agreement with Wilson and Rice (1968), Macias et al (1998Macias et al ( , 2002 and Anjum, and Bajwa (2005). Results presented in Table 4 raveled that the differences between crops extracts concentrations were significant for root length (cm) Cheema (1988), has reported similar selective effects of allelochemicals and Leather (1982Leather ( , 1983 and Naseem (1997), who reported that allelochemicals have selective effect against weed germination and dry matter accumulation.…”

“…Anaya reported that soil incorporation of sunflower residues markedly inhibited density of dicot weeds by 66% and controlled 85% of total weed growth. Sunflower possesses chlorogenic acid, isochlorogenic acid, α-naphthol, scopolin and annuionones [56][57][58][59].…”

Objective: This paper mainly discusses the Allelopathic potential of wheat. Methods: This paper is prepared by reviewing the latest academic literatures. Result: The green revolution in the 1960s caused an increase in the demand for food. The agricultural sector and farmers tended to spend more time on the agricultural work but the crop yield was suppressed by the weeds. Hence, the usage of herbicide insecticides, fungicides and others chemicals had been increased. Although herbicides are efficient for weed controls, the continuous uses had gradually stimulated the weeds developing an effecttive resistance to the chemicals. Wheat (Triticum aestivum L.) is known as allelopathic against crops and weeds. Allelopathy of wheat (Triticum aestivum L.) has been extensively examined for its potentials in weeds management. The al-lelopathic activity of wheat has been attributed to hydroxamic acids, the related compounds and phenolic acids. Therefore, it could effectively reduce herbicide uses in order to maintain an eco-friendly environment and a cost-effective weed control.

“…Sunflower contains allelochemicals viz. chlorogenic acid, isochlorogenic acid, á-naphthol, scopolin, and annuionones (Macias et al, 2002;Anjum & Bajwa, 2005). The members of Brassicaceae family contain glucosinolates that upon hydrolysis yield isothicynates (Jiménez-Osornio & Gliessman, 1987), and isoprenoids and benzoids (Tollsten & Bergstrom, 1988) which exert allelopathic effects on germination and growth of other species (Norsworthy et al, 2005).…”

Effect of crop residues applied isolated or in combination on the germination and seedling growth of horse purslane (Trianthema portulacastrum)

-Soil incorporation of crop residues can lead to weed suppression by posing allelopathic and physical effects. Allelopathic potential of the crops sorghum, sunflower, brassica applied as sole or in combination for horse purslane (Trianthema portulacastrum) suppression was evaluated in a pot investigation. Chopped crop residues alone and in combination were incorporated at 6 g kg -1 soil (12 t ha -1), and a weedy check was maintained. Germination traits time to start germination; time to 50% emergence, mean emergence time, emergence index and final germination percentage were negatively influenced by residue incorporation. Crop residues also exerted a pronounced negative influence on the shoot and root length of horse purslane. Significant suppression in leaf and root score and leaf area per plant was also observed. A combination of sorghum and sunflower residues accounted for maximum (71%) seedling mortality. Soil incorporation of allelopathic crop residues can be employed for horse purslane management.Keywords: residues, allelopathic, sorghum, sunflower, brassica, Trianthema portulacastrum, germination/seedling growth, suppression.RESUMO -A incorporação de resíduos vegetais pode levar à supressão de plantas daninhas devido a efeitos físicos, químicos e alelopáticos. O efeito alelopático potencial de resíduos de sorgo, girassol e canola, aplicados isolados ou em combinação, foi avaliado em relação à germinação e crescimento inicial de beldroegas-cavalo (Trianthema portulacastrum) em experimento em vasos. Os resíduos vegetais foram picados e incorporados no solo na quantidade de 6 g kg -1 de solo, que é equivalente a 12 t ha -1 ; manteve-se também um tratamento sem resíduos. O tempo para iniciar a germinação, tempo de emergência de 50% (E50), tempo médio de emergência, índice de emergência e porcentagem final de germinação foram influenciados negativamente pela incorporação dos resíduos. A palhada também exerceu forte influência negativa sobre o crescimento da parte aérea e comprimento radicular de beldroegas-cavalo. Também foi observada supressão significativa na contagem de folhas e raízes e área foliar. A combinação de resíduos de sorgo e girassol causou a máxima mortalidade de plântulas, que foi de 71%. A incorporação de resíduos vegetais de culturas pode ser utilizada para o manejo de beldroegas-cavalo.
