    This study was conducted to determine the effects of 50% reduced and 50% increased doses of some herbicides used in chickpea cultivation on seed yield and mineral content of the seed. Field experiments were established in Isparta province of Turkey during 2016-2017 plant growing season. Experiments were conducted to the completely randomized block design with 3 repetitions. Fourteen different weed control treatments were tested (control (T1), hoeing (T2) suggested doses and 50% reduced / increased doses of herbicides that contain active substances of linuron (T3-T5), aclonifen (T6-T8), pendimethalin (T9-T11) isoxaflutale + cyprosulfamide (T12-T14)), respectively. As plant material, drought and lodging tolerant ILC 195 chickpea cultivar seeds were used. Results showed that chlorophyll a, chlorophyll b content of green part of plants, phosphorus, potassium, calcium, iron, zinc, protein content of seeds, 100 seed weight and seed yield were significantly affected by the herbicides treatments. The highest positive effects on both the seed yield and the chemical composition of the seed were obtained at the dose of 125 ml/ha and 250 ml/ha of isoxaflutale + cyprosulfamide (240 g/l) and at 1500 ml/ha and 3000 ml/ha of pendimethalin herbicide treatments in chick pea cultivation.
