Abstract
Minimum tillage is proposed for saving water or increasing water productivity of crops. Here we compare the yield, irrigation water use and water productivity of wheat in strip planting (SP), bed planting (BP) and conventional tillage (CT). SP and BP were carried out using a versatile multi-crop planter mounted on a 2-wheel tractor. Residue treatments were 20% or 50% of rice straw retained. The study was carried out on long-term replicated plots at Rajshahi, Bangladesh (silty clay loam soil), which were established in 2010. The current experiment was conducted in cool dry seasons of 2015-2017. In 2015, the yield of wheat under SP (5.10 t ha-1) and BP (5.03 t ha-1) were significantly higher (P<0.05) than under CT (4.34 t ha-1). Over the three years, SP saved 11-33 % water compared to CT; while water input was 16-27 % lower in BP. Water productivity of wheat was higher in SP and BP compared to CT in three years. In 2015, water productivity of wheat was 2.06, 2.01 and 1.25 g grain kg-1 water for SP, BP and CT respectively. Similarly, water productivity of wheat in 2016 and 2017 was highest (2.32 and 1.95 g grain kg-1 water respectively) in SP. Water productivity of wheat in 2016 and 2017 was intermediate for BP between SP and CT. Minimum tillage approaches have the potential to increase production and water productivity in the northwest region of Bangladesh; however, the challenge will be to apply them in the annual crop rotations on smallholder-farms.
