Abstract
Sowing of chickpea in the heavy textured soils of the High Barind Tract of Bangladesh with minimum tillage technology aims to increase the timely planting of large areas during a relatively short sowing window before soil water limits germination and emergence. However, the seedbed conditions into which chickpea is sown needs to be better quantified, so that limiting factors which affect germination and emergence can be identified. The soil physical characteristics of importance are soil water, strength and aeration. Growth cabinet studies have identified the fastest germination and emergence of chickpea to be in soils which have gravimetric water contents of 17 to 18 %, at soil water contents above and below this germination and emergence are delayed. Field experiments in Bangladesh have been monitored to determine in-field conditions at sowing. These field and laboratory experiments will be used to quantify the soil physical properties which limit the germination and emergence of chickpea in the HBT of Bangladesh.
