Water productivity of spring maize under modified soil microenvironment

In addition to warming scenarios, the state of Punjab is suffering from limiting water availability for agriculture as the water table is depleting at an alarming rate in most parts of the state. [...]a dual challenge of warming climate and low input water availability is being faced while popularizing spring maize in the state. Various other studies have also reported that subsurface application of farmyard manure is useful for improving soil health, water productivity and reducing emission of green house gases to the atmosphere (Dell et al, 2011; Maguire et al, 2011 and Way et al, 2012).T hus, from the study it can be concluded that need based irrigation scheduling and water application (I2, IW/CPE=1.00) in combination with sub-surface manuring can be helpful in managing crop water productivity in view of limiting water availability and changing climatic scenarios under Punjab condit ions.
