Keywords:

Abstract
A field experiment was conducted in calcarious Vertisol at the Irrigation Water Management Research Centre(IWMRC) Belavatgi, Navalgund taluk of Dharwad, Karnataka, during kharif 2016-17 and 2017-18. The experiment waslaid out in split plot design. The main plot consisted of irrigation scheduling, whereas the sub-plot included integratednutrients management levels with three replications.The pooled data on sunflower during 2016-17 and 2017-18 revealedthat, irrigation scheduling at 0.8 IW/CPE and application of RPP + PSB + GM (one row of sunhemp between two rowsof sunflower) has significantly noticed higher oil content (41.83), oil yield (764.88), protein content (20.47), gross returns(` 63935 ha-1), net returns (` 26339 ha-1) and BC ratio (1.70). However, the application of RPP + PSB + GM and 0.6 IW/CPE has significantly registered higher WUE (6.64 kg ha - mm-1) of sunflower at harvest.
