Over the past decades rapid growth in industrial and agricultural activities, waste disposal and etc., have significantly contributed to extensive soil contamination. Total petroleum hydrocarbons (TPHs) are one of the most common groups of persistent organic contaminants. To date, many developing countries like Iran have almost completely relinquished remediation of oil-polluted soils due to th...

Barley is integrated with other crops to inhibit weed growth, through allelopathic interactions. Effects of barley on growth of other crops, weeds and autotoxicity among cultivars result primarily from allelopathy mediated by allelochemicals released from plant components and/or exuded from living roots. A limited number of allelochemicals are identified that contributes to allelopathic effecti...

an isolate of fusarium moniliforme, a pathogen of winter wild oat (avena ludoviciana), was obtained from tehran province, iran, in 1994. a host range test performed on wheat, barley, maize, rye, millet, crested wheatgrass, faba bean, red bean, green bean, sunflower, soybean, oilseed rape, cotton, safflower, cucumber, water melon, berseem clover, and sainfoin, resulted in no symptom induction by...

in order to evaluate forage quality in intercropping, two field experiments were carried out based on randomized complete block design with three replications at the agricultural research station, faculty of agriculture, university of tabriz, iran, in 2005-2006 and 2006-2007 growing seasons. two maize (zea mays l.) hybrids (sc704, sc301), vetch (vicia villosa), bitter vetch (vicia ervilia), ber...

Intercropping legumes with cereals for forage production is a practical multi-cropping technique to increase yield and improve land use efficiency. In 3-year cropping sequence, alfalfa (Medicago sativa L.) intercropped corn (Zea mays may overall economic sustainability over either crop alone. The objective of this study was assess productivity corn-alfalfa intercropping system its effect on wee...

Annual medic is an annual crop which performs well in various forage cropping systems. However availability of medic seeds is a major challenge for livestock producers in Iran. This study was conducted to determine if intercropping annual medic with barley can produce supplement medic seeds while barley grain yield as the main crop is not compromised. Two experiments were carried out at the exp...

A field experiment was conducted during 2013-14 to 2015-16 at Central Soil Salinity Research Institute, Regional Station, Lucknow find out the alternate rice (Oryza sativa L.)- wheat (Triticum aestivum L.) cropping system under partially reclaimed sodic soils. Four systems, viz. L.), sorghum (Sorghum bicolor)-berseem (Trifolium alexandrinum), sweet basil (tulsi) (Ocimum basilicum L.)-matricaria...

Certain amino acids induce inhibitory effects in plant growth due to feedback inhibition of metabolic pathways. The inhibition patterns depend on plant species and the plant developmental stage. Those amino acids with inhibitory action on specific weeds could be utilized as herbicides, however, their use for weed control has not been put into practice. Orobanche minor is a weed that parasitizes...

introduction sustainability of agricultural systems may improve due to intercropping as a result of diversity increasing. marigold (calendula officinalis) is a major medicinal plant from asteraceae family, though weeds suppress it because of lower competitiveness against weeds. mungbean (vigna radiata) is a pulse crop from fabaceae family and is one of the major nutritive sources especially in ...
