Weed species diversity and population indices in irrigated and rain-fed chickpea (CicerarietinumL.)
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 7, Issue 4
Abstract
This study was conducted to evaluate the species diversity and population indices of weeds in irrigated and rainfed chickpea (Cicerarietinum L.) fieldsof Kermanshah Iran, in 2014.The irrigated, spring and winter rain-fed fields of chickpea were selected for sampling of weed species population. The field surveys were made during the chickpea flowering stage. The weeds in 0.25 m2quadrats were harvested and the frequencyindex, uniformity, density, averagedensityandabundance indexwas calculated.The results showed that in irrigatedchickpea fields thejohnsongrass(Sorghum halepense(L.) Pers.)andlambsquarters (Chenopodium albumL.) had the highest frequency, uniformity, density and abundance index.In the winter rain-fed chickpea the common hedge parsley (Torilisarvensis (Huds) and wild oat (AvenaludovicianaDurieu.) and inthe spring rain-fed chickpea the common liquorice(GlycyrrhizaglabraL.) and Torilisarvensis(Huds) had the highest frequency, uniformity, density and abundance index. Generally we can conclude that the cropping system could affect the weed species diversity and composition.
