Response of Dicoccum Wheat for Row Spacings and Fertigation Levels Under Raised Bed

Experiments was conducted during 2014–2015 rabi season at ARS, Mudhol to probe the response of three row spacings viz., 20, 22.5 and 30 cm and five fertigation levels (100% RPP, 75% RDF, 100% RDF 125% RDF ha⁻¹ under raised bed condition, and single control plot 100% RPP ha⁻¹ under flat bed condition). The row spacing 22.5 cm and fertigation of 125% RDF ha⁻¹ recorded significantly higher growth parameters namely LAI, total dry matter at different phenological stages and number of tillers m⁻¹ row length. Significantly higher grain yield (7783.33 kg ha⁻¹) and straw yield (9004 kg ha⁻¹) was recorded by row spacing 22.5 cm and fertigation of 125% RDF ha⁻¹. The increase in grain and straw yield in row spacing 22.5 cm and fertigation of 125% RDF ha⁻¹ could be the number of grains per ear head (with husk) (46.33), grain weight per ear head (with husk) (3.26 g) and thousand grain weight (with husk) (59.39 g). The row spacing 22.5 cm and fertigation of 125% RDF ha⁻¹ recorded significantly higher gross returns (Rs. 153286 ha⁻¹), net returns (Rs. 125917 ha⁻¹) and B: C (5.60) as compared to rest of the treatment combination.
