“…This is consistent with the findings of Nakamoto et al [17] and Gruber et al [32], who suggested capable solutions for reaching or maintaining a tolerable weed infestation level in case of reduced soil disturbance. Chemical weed control on the cereal stubbles was an additional solution for maintaining limited coverage of weeds by the end of summer.…”

“…Weed germination may be limited by the blocking of the illumination of the soil surface and by allelopathic effects of the plant residues [9]. The trend of a gradual decrease was also observed in weed density and biomass in rainfed conditions, when there was an increase in the straw mulch rate [16][17]. However, more effective soil moisture conservation due to the effectual mulch cover may facilitate weed emergence even in dry seasons or in dry areas.…”

“…The better emergence and more tillers in minimum tillage would be attributed to appropriate and sufficient moisture availability being 11.10 * = Significant at p<0.05, ** = Significant at p<0.01, ns = non-significant conserved in reduced tillage (Chiroma et al, 2006;Thomas et al, 2007;Sławinski et al, 2012) for proper sprouting and germination initiation of Phase II seedling stage. The more organic C (Al-Kaisi and Yan, 2005;Guzman et al, 2006;Nakamoto et al, 2006) and/or soil nitrogen (Soon et al, 2001) or slighter N leaching (Sainju et al, 2006) possibly have improved crop stand or establishment in term of shoots and tillers development.…”

The objective of the study was to examine the treatment effects on phenology, establishment and yield of succeeding wheat crop. Result showed that wheat phenology except days to emergence was not affected by different TS however; early emergence (10 days) was observed in minimum tillage rather than conventional and deep tillage system. Nitrogen fertilization (120 kg N ha -1 ) enhanced days to phenological observations, while no significant variation in days to emergence and physiological maturity were recorded among SM practices, however; stubble incorporation delayed the booting and anthesis stage compared to burning and removing. Minimum tillage improved emergence, tillers and grain yield (3134 kg ha -1 ) compared to deep tillage systems. Nitrogen fertilization at the rate of 120 kg ha -1 and maize stubble incorporation prior to wheat sowing also improved emergence, tillers, plant height and grain yield compared to control and stubble removal or burning. It is concluded from current study that maize stubble incorporation with recommended dose of fertilizer N (120 kg ha -1 ) prior to wheat sowing delayed phenology, and improved wheat establishment and yield under minimum tillage in a continuous cereal based cropping system instead of stubble burning and removal.

“…Success with adoption of minimum and no-tillage, as reported in several publications, is attributed to the use of herbicides to control weeds, reduce inherent yield loss and cope with lack of labor in most countries [25][26][27]. Indeed in many cases, in minimum and no-tillage, herbicides are considered as an alternative to the primary tillage, done in tillage-based systems, for pre-planting weed control [28][29][30][31][32][33][34][35][36].…”

Land degradation and soil fertility deterioration are two of the main causes of agricultural production stagnation and decline in many parts of the world. The model of crop production based on mechanical soil tillage and exposed soils is typically accompanied by negative effects on the natural resource base of the farming environment, which can be so serious that they jeopardize agricultural productive potential in the future. This form of agriculture is destructive to soil health and accelerates the loss of soil by increasing its mineralization and erosion rates. Conservation agriculture, a system avoiding or minimizing soil mechanical disturbance (no-tillage) combined with soil cover and crop diversification, is considered a sustainable agro-ecological approach to resource-conserving agricultural production. A major objective of tillage is supposed to be weed control, and it does not require very specific knowledge because soil inversion controls (at least temporarily) most weeds mechanically (i.e., by way of burying them). However, repeated ploughing only changes the weed population, but does not control weeds in the long term. The same applies to the mechanical uprooting of weeds. While in the short term some tillage operations can control weeds on farms, tillage systems can increase and propagate weeds off-farm. The absence of tillage, under conservation agriculture, requires other measures of weed control. One of the ways in which this is realized is through herbicide application. However, environmental concerns, herbicide resistance and access to appropriate agro-chemicals on the part of resource-poor farmers, highlight the need for alternative weed control strategies that are effective and accessible for smallholders adopting conservation agriculture. Farmers in semi-arid regions contend with the additional challenge of low biomass production and, often, competition with livestock enterprises, which limit the potential weed-suppressing benefits of mulch and living cover crops. This paper reviews the applicability and efficacy of various mechanical, biological and integrated weed management strategies for the effective and sustainable management of weeds in smallholder conservation agriculture systems, including the role of appropriate equipment and prerequisites for smallholders within a sustainable intensification scenario.Keywords: smallholder farming; conservation agriculture; sustainable and ecological weed management; preventive; cultural and direct control methods of weed management
