“…[63,64] Liebman and Dyck [64] suggested that intercropping offers weed control advantages over sole crops in two ways; they (i) suppress weed growth through competition and allelopathy and thus more effectively use available resources at the expense of weeds, and (ii) provide yield advantages either using resources that are not exploitable by weeds or using converting resources to harvestable material more efficiently than sole crops.…”

Conventionally bred (CHT) and genetically modified herbicide-tolerant (GMHT) crops have changed weed management practices and made an important contribution to the global production of some commodity crops. However, a concern is that farm management practices associated with the cultivation of herbicide-tolerant (HT) crops further deplete farmland biodiversity and accelerate the evolution of herbicide-resistant (HR) weeds. Diversification in crop systems and weed management practices can enhance farmland biodiversity, and reduce the risk of weeds evolving herbicide resistance. Therefore, HT crops are most effective and sustainable as a component of an integrated weed management (IWM) system. IWM advocates the use of multiple effective strategies or tactics to manage weed populations in a manner that is economically and environmentally sound. In practice, however, the potential benefits of IWM with HT crops are seldom realized because a wide range of technical and socio-economic factors hamper the transition to IWM. Here, we discuss the major factors that limit the integration of HT crops and their associated farm management practices in IWM systems. Based on the experience gained in countries where CHT or GMHT crops are widely grown and the increased familiarity with their management, we propose five actions to facilitate the integration of HT crops in IWM systems within the European Union.ARTICLE HISTORY

“…A number of leguminous cover crops have been screened for weed suppression. Cowpea has been identified as an effective cover crop for suppression of weed biomass and density (Bilalis et al, 2010). Its effectiveness is attributed to its prostrate growth habit which can reduce light interception by weeds and hence reduce weed germination and growth (Zaviehmaradat et al, 2013).…”

The use of herbicides amongst smallholder farmers is minimal because herbicides are expensive and they require specialized application equipments. Weeds are problematic in conservation agriculture where herbicides are expensive for smallholder farmers. The use of cover crops can help to suppress weed growth and development by creating an environment which is not suitable for weeds survival. Cowpea (Vigna unguiculata (L.) Walp) dolichos lablab (Lablab purpureus L.) and velvet bean (Mucuna pruriens (L.) DC) were evaluated for biomass accumulation and weed suppression under conservation agriculture system in two contrasting experimental sites: Ukulinga and Bergville in KwaZulu-Natal. Bare plot and herbicide treatments served as controls. Treatments were laid in a randomized complete block design, replicated three times. Mucuna pruriens (L.) DC had the highest biomass accumulation in both sites Bergville (0.72 t/ha) and Ukulinga (1.59 t/ha). Cowpea had the lowest biomass accumulation in Bergville (0.59 t/ha) and lablab was the lowest in Ukulinga (0.88 t/ha). Lablab was effective in suppressing weed biomass in Bergville (P < 0.05). Cowpea performed best in suppressing weed biomass in Ukulinga (P < 0.05). The results suggest that cowpea and lablab can be effective for weed suppression and therefore can be recommended for use in conservation agricultural systems.

“…In organic agriculture, intercropping is receiving increasing attention as it offers potential advantages for increasing sustainability in crop production [8].Intercropping is a cultural practice which increases competition between crops and weeds. It can increase light interception in a weakly competitive crop and can contribute to weed suppression in a long-term strategy for weed management [9] Eroded Agriculture Land Conservation Method Based on Dose Response Economic Valuation for Sustainable Land Maintain: A Case Study in Bompon Watershed, Magelang, Central Java II.…”

Abstract-Central Java has unique watershed that located in Magelang. Bompon watershed has kind of material that decayed of volcano dust parental material which the material was influence by alteration process, placed at hilly morphology, and produce very thick soil. Erosional process cause loss of some nutrients, especially nitrogen potentially occur in this type of soil. Erosion and data survey processed by dose response method are the main procedure of the research. Dose response method can be used to determine the financial loss occur by the erosional process, and Rp 12,934,024 (around 994.923 USD) is financial loss because of the erosional process in each hectare of agricultural land. Conservations are better chosen as the solution to maintain the sustainability of the agricultural land in order to protect from decreasing productivity, besides it has cheap price equal to the financial loss occur. Best conservations suggested to be applied are combining the vegetative and physical method, which are planting peanut and making tight ridges.
