An field experiment was carried out to study the “Effect of foliar spray of biostimulants and chelated micronutrients on yield, quality and nutrient uptake of sunflower” during rabi 2023-24 at Research field of Oilseed Research Unit, Dr. PDKV, Akola. The experiment was framed with seven treatments viz, T₁- Absolute control, T₂ - GRDF, T₃ - GRDF + Foliar spray of chelated micronutrient mixture @ 0.25% at 35 and 55 DAS, T₄- GRDF + Foliar spray of vermiwash @ 10% at 35 and 55 DAS, T₅- GRDF + Foliar spray of humic acid @ 1% at 35 and 55 DAS, T₆- GRDF + Foliar spray of vermiwash @ 10% + chelated micronutrient mixture @ 0.25% at 35 and 55 DAS and T₇- GRDF + Foliar spray of humic acid @ 1% + chelated micronutrient mixture @ 0.25% at 35 and 55 DAS replicated thrice using randomized block design. The results indicated that the yield, quality and nutrient uptake of sunflower were significantly influenced by different treatments. However, yield, quality and uptake of nutrients in sunflower significantly influenced by the application of GRDF + Foliar spray of humic acid @ 1% + chelated micronutrient mixture @ 0.25% at 35 and 55 DAS (T₇). While, lowest yield, quality and uptake of nutrients in sunflower were recorded in absolute control (T₁).
