Evaluation of options for increasing yield and water productivity of wheat in Punjab, India using the DSSAT-CSM-CERES-Wheat model

Timsina, J.; Godwin, D.; Humphreys, E.; Yadvinder-Singh; … - In: Agricultural Water Management 95 (2008) 9, pp. 1099-1110

The DSSAT-CSM-CERES-Wheat V4.0 model was calibrated for yield and irrigation scheduling of wheat with 2004-2005 data and validated with 13 independent data sets from experiments conducted during 2002-2006 at the Punjab Agricultural University (PAU) farm, Ludhiana, and in a farmer's field near...

Yield and water productivity of rice as affected by time of transplanting in Punjab, India

Mahajan, G.; Bharaj, T.S.; Timsina, J. - In: Agricultural Water Management 96 (2009) 3, pp. 525-532

Early planting of rice crop during the period of peak evaporative demand results in substantial mining of ground water and threats the sustainability of rice production in Punjab, northwest India. In order to increase yield and water productivity, arrest the mining of ground water, and achieve...

Simulation of the evaporation of soil water beneath a wheat crop canopy

Balwinder-Singh; Eberbach, P.L.; Humphreys, E. - In: Agricultural Water Management 135 (2014) C, pp. 19-26

The evaporation of soil water (Es) is an important component of the water balance in cropping systems. Although Es is considered to be non-beneficial (not directly related to crop production), it may indirectly influence water availability for transpiration which is directly related to crop...

The effect of rice straw mulch on evapotranspiration, transpiration and soil evaporation of irrigated wheat in Punjab, India

Balwinder-Singh; Eberbach, P.L.; Humphreys, E.; Kukal, S.S. - In: Agricultural Water Management 98 (2011) 12, pp. 1847-1855

Soil evaporation (Es) is considered to be a non-productive component of evapotranspiration (ET). So, measures which moderate Es may influence the amount of water available for transpiration (T), the productive component of ET. Field experiments investigating the effects of rice straw mulch on...
