abstract
A field trial was conducted during Rabi season of 2020-21 and 2021-22 to study the "Optimizing emmer wheat yield: Strategies for lodging prevention with plant growth regulators". The study was organized using a split-plot design, employing three replications. The experimental treatments included four genotypes in the main plot and five treatments in the sub-plots. The results indicated that the genotype of MACS 2971 with foliar application of ethephon @ 30 ppm l^-1 of water (V₁G₅) recorded significantly lower plant height (66.00 cm), lodging score (0.83%), higher number of effective tillers (391.83 m^-2), grain yield (44.24 q/ha), straw yield (72.99 q/ha), biological yield (117.73 q/ha), gross returns (₹. 1,62,851 ha^-1), net returns (₹. 1,27,530 ha^-1) and B:C ratio (4.61) followed by V₁G₃, V₂G₃, V₂G₅, V₃G₃ and V₄G₅. Where, as significantly higher plant height, lodging score, lower number of effective tillers, grain yield, straw yield, biological yield and lower economic returns was (V₄G₅) recorded in without foliar application of plant growth regulators in gokak local genotype.
