Abstract: Weed interference can reduce chickpea growth and, therefore, productivity depending on the period of coexistence and the nutritional status of the crop, among other factors. A study was performed over two crop years to estimate the critical period of weed interference (CPWI) during chickpea production under three doses of nitrogen (N) fertilizer topdressing (0, 50, and 75 kg N ha-1). The experiments were conducted at 0, 7, 14, 21, 28, 35, 42, 56, 63, and 140 days after emergence (DAE) of chickpea/weed coexiste… Show more

“…Bio-chemicals in the weeds that are growing with crops, have a specialized mechanism which can cause inhibition on growth and metabolism, fresh and dry matter along with decreasing level of carbon content of crop plants (Zhu et al 2010). Weed manure incorporated into soil could decrease the soil essential elements due to the presence of certain phenolic compounds that have been resulted in the reduction of plant height, biomass content and yield of leguminous crops i.e., Chickpea (Amaral et al 2018). Amounts of biochemicals vary from one part to another part of the same weed, and their effects could also be variable within the same crop species (Khan et al (2018).…”

“…In chickpea cultivation, studies on the inoculation of Bacillus spp. under Brazilian tropical conditions as well as on plant response after mineral nitrogen (N) application are scarce (Amaral et al, 2018;Almeida Neta et al, 2020). N is considered an essential nutrient for legume crops without high symbiotic efficiency.…”

“…When present in areas of chickpea cultivation, weeds cause losses in production of from 25 to 97% (Al-Thahabi et al, 1994;Mohammadi et al, 2005;Paolini et al, 2006;Tepe et al, 2011). In Brazil, losses in chickpea yield due to weed interference have been estimated at 70%, on average, irrespective of nitrogen fertiliser management (Amaral et al, 2018).…”
