Crop sequence is an important management practice that may affect durum wheat (Triticum durum Desf.) production. Field research was conducted in 2007-2008 and 2008-2009 seasons in a rain-fed cold Mediterranean environment to examine the impact of the preceding crops alfalfa (Medicago sativa L.), maize (Zea mays L.), sunflower (Helianthus annuus L.), and bread wheat (Triticum aestivum L.) on yie...

At least 16 nutrient elements are required by plants for growth and survival, but the factors affecting element concentration and their temporal evolution are poorly understood. The objective was to investigate i) element concentration pattern in winter wheat as affected by crop developmental stage and weather, and ii) whether, in the short term, element stoichiometry reflects the type of prece...

> Sowing crops following cover crops on forage may cause injuries andproductivity reduction, due reasons as allelopathy or glyphosate residues. Theobjective of this study was to evaluate the influence of differing periods betweencover crop (Urochloa ruziziensis) desiccation with glyphosate and sunflower(Aguará 4) sowing in a no-tillage system on crop development and productivity.Two assays were...

Striga hermonthica remains one of the greatest biological threats to cereal production in the savannahs of sub-Saharan Africa. Control efforts at the International Institute of Tropical Agriculture (IITA), Nigeria, focus on developing integrated S. hermonthica management (ISM) options such as legume-cereal rotation, use of host–plant resistance, soil-based biological control exploiting enhancem...

Background There is little information on how different soil cover systems influence the residual effect of pre-emergent herbicides used in soybean cultivation Brazil. Objective The objective was to compare persistence a Latosolic Dystrophic Red Nitosol presence or absence black oat straw surface. Methods were chlorimuron-ethyl (40.0 g ai ha-1), diclosulam (70.1 flumioxazin (100.0 ha-1) and saf...

In sorghum and mungbean – lentil cropping system, field experiments were conducted for three successive years to assess the effect of mung bean residue incorporation on sorghum and succeeding lentil productivity along with different doses of phosphorus (P; 0, 30, 60 kg ha−1) applied to these crops. The level of soil fertility was also tested with or without incorporation of mung bean residue. T...

Habitat disturbance affects numerous ecosystem components and processes, but its effect on continuous soybean system is less available. Soybean was seeded following six preceding crops, including grain soybean (Glycine max L. Merill.), wheat (Triticum aestivum L.), sugar beet (Beta vulgaris L.), tobacco (Nicotiana tabacum L.), corn (Zea mays L.) and hemp (Cannabis Satia L.), on a Mollisol ...

Nine cultivars of winter wheat were compared in organic and conventional crop rotation systems. Bread-making quality was evaluated using three parameters [thousand-kernel weight (TKW) in g, volume weight in g/l, protein content in %]. Grain yield, TKW and protein content of winter wheat in organic cropping system were significantly lower as compared to any intensity in conventional cropping sys...

A pronounced residual effect of organic and inorganic fertilizers, applied in maize crop was observed on yields of maize-gobhi sarson cropping system. The experiment was conducted with 10 treatments of N, P, K, FYM, crop residue and zinc sulphate nutrients. The highest growth, yield and yield components of maize crop were recorded with 100% recommended fertilizer dose-RFD + ZnSO4 20 kg/ha and t...
