WEED MANAGEMENT IN CHICKPEA (Cicer arietinum L.) THROUGH IDENTIFICATION OF POST-EMERGENT HERBICIDES AND HERBICIDE TOLERANT GENOTYPES FOR FOOD SECURITY

Chickpea is very significant among legumes, due to its nutritional value, growing and consuming all over the world. However, due to non- availability of herbicide tolerant chickpea genotypes and selective post-emergent herbicide weeds are effecting upto 80% of grain yield. Series of experiments were conducted from 2017-2020 at two locations Faisalabad (irrigated region) and Kallurkot (Thal, arid region) to evaluate 600 chickpea genotypes both (Desi+Kabuli) for herbicide tolerance and five herbicides (Carfentrazone 20g/A, Flumentusulum 30g/A, Penoxaden 330ml/A, Meteribuzine 250g/A, Isoproturon 800g/A) were tested to identify selective post emergent herbicide. Flumentusulum effectively controlled Asphodelus tenuifolius in Thal region and Chenopodium murale and Chenopodium album in irrigated region without effecting chickpea plant and grain yield. The grain yield losses of chickpea due to weeds in flumentusulum were up to 14.8% and controlled 98.6% of weeds. The Kabuli lines K-16025, K-204015, K-70008 and desi chickpea lines D-16004, D-05002 and D-89129 indicated tolerance against fluementusulum, carfentrazone and isoproturon and indicated high grain yield. The yield comparison at two locations manifested high grain yield at Pulses Research Institute Faisalabad (irrigated region).
