Yield Response to Six Plant Populations in Chickpea Under Drip Irrigation.

Six plant populations were evaluated in chickpea cv ‘Blanco Sinaloa 92’ under drip irrigation in a semiarid  environment. Populations were 5, 7.5, 10, 12.5, 15 and 17 plants m^-2, planted under raised beds 1.6 m apart in a two-rows planting at 0.4 m apart. There were significant differences among plant populations for grain yield. The highest yield was obtained from 10 to 15 plants m². Higher plant populations decreased grain yield in 14%, whereas in lower plant population grain yield decreased between 12 and 17%. There were no differences among plant populations for 100 seeds weight and percent of exportable grain.
