An experiment was carried out at student farm, College of Agriculture, Rajendranagar, Hyderabad, Telangana, in sandy loam soils during rabi 2020 to study the effect of hormones on growth and yield of mustard under Southern Telangana Agro-climatic conditions. The experiment was laid out in randomized block design with ten treatments. The treatments comprised were: T1-Control (RDF 60:40:40 N, P2O5, K2O kg ha-1), T2 (RDF + foliar spray of GA3 @ 45 ppm at flowering), T3 (RDF + foliar spray of GA3 @ 45 ppm at pod development), T4 (RDF + foliar spray of GA3 @ 45 ppm at flowering and pod development), T5 (RDF + foliar spray of humic acid @ 1.5% at flowering), T6 (RDF + foliar spray of humic acid @ 1.5% at pod development), T7 (RDF + foliar spray of humic acid @ 1.5% at flowering and pod development), T8 (RDF + foliar spray of GA3 @ 45 ppm fb humic acid @ 1.5% with 2 days interval at flowering), T9 (RDF + foliar spray of GA3 @ 45 ppm fb humic acid @ 1.5% with 2 days interval at pod development) and T10 (RDF + foliar spray of GA3 @ 45 ppm fb humic acid @ 1.5% with 2 days interval at flowering and pod development). Results indicated that, application of RDF + foliar spray of GA3 @ 45 ppm fb humic acid @ 1.5% with 2 days interval at flowering and pod development (T10) and application only at flowering (T8) gave the similar and higher yields and economic returns. As the cost of cultivation of T10 was higher than T8, BC ratio was higher for T8.
