Mungbean crop due to short duration and has a distinct advantage over other legumes to be grown in both summer and kharif season has a good potential to be used in the intensive cropping system. A field experiment was conducted at the research farm of the Department of Soil Science, Punjab Agricultural University, Ludhiana during summer seasons 2016, 2017 and 2019 to study the deep tillage and irrigation effects on water productivity of summer mungbean. Treatments included three irrigation regimes (I0.75, I0.50, and I0.25) in the main plots and two tillage systems (conventional tillage-CT and deep tillage-DT) in the subplots. Penetration resistance was observed to be lower in DT than CT throughout the depths of measurement. Root growth was measured at podding and least frequent irrigation regime I0.25 and DT increased root growth (root mass density) more so in the deeper layers (i.e. from 60-90 cm). Yield attributes were much influenced by deep tillage and effects were more pronounced in 2019. Profile moisture storage was about 3 cm higher in more irrigated regimes (I0.50 and I0.75). Increase in irrigation frequency increased the mean seasonal water use by the crop and it varied from (25.2 cm to 39.2 cm) during the three cropping seasons. It was also higher under DT in less and medium frequent regimes (I0.25 and I0.50) compared to CT. Grain yield was influenced by both irrigation and deep tillage. Medium irrigated I0.50 regime had maximum grain yield followed by I0.75 and I0.25 irrigation regimes. DT enhanced the mean grain yield over CT by 0.03 t/ha in 2016 and 0.06 t/ha in 2017 and 2019 respectively. An increase in irrigation frequency reduced mean water productivity and it varies from 3.57 kg/ha/mm to 2.00 kg/ha/mm; DT had a tendency to increase water productivity during the three cropping seasons.
