A field experiment was conducted at the College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand,Gujarat during kharif season of the year 2021. The soil in the experimental plot was loamy sand that was slightly alkaline (pH 8.18) with good drainage and moisture retention capacity. The experimental soil was low in organic carbon (0.24%), low in available nitrogen (211.02 kg/ha), medium in available phosphorous (29.63 kg/ha), medium in available potash (152.14 kg/ha), medium in available sulphur (10.04 mg/kg) and medium in available iron (5.56 mg/kg). The experiment was laid out in randomized block design with 10 treatments replicated four times and applied ethrel @ 100 ppm as a seed treatment for breaking seed dormancy. The treatments details areT1: RDF (12.5:25:00 NPK kg/ha), T2: RDF + 20 kg S/ha through gypsum, T3: RDF + 20 kg S/ha through gypsum + 250 ppm nano Fe foliar spray,T4: RDF + 40 kg S/ha through gypsum, T5:RDF + 40 kg S/ha through gypsum + 250 ppm nano Fe foliar spray, T6:RDF + 20 kg S/ha through bentonite sulphur , T7:RDF + 20 kg S/ha through bentonite sulphur + 250 ppm nano Fe foliar spray, T8: RDF + 40 kg S/ha through bentonite sulphur, T9:RDF + 40 kg S/ha through bentonite sulphur + 250 ppm nano Fe foliar spray, T10:RDF + 250 ppm nano Fe foliar spray. The effect of sulphur and nano Fe application registered significant impact on the quality parameters of groundnut viz., oil and protein content. Application of treatment T9: RDF + 40 kg S/ha through bentonite sulphur + 250 ppm nano Fe foliar spray was reported significantly higher oil (49.10%) and protein (24.79%) content. However, it did not differ significantly with treatment T3: RDF + 20 kg S/ha through gypsum + 250 ppm nano Fe foliar spray, T4: RDF + 40 kg S/ha through gypsum, T5: RDF + 40 kg S/ha through gypsum + 250 ppm nano Fe foliar spray, T7: RDF + 20 kg S/ha through bentonite sulphur + 250 ppm nano Fe foliar spray and T8: RDF + 40 kg S/ha through bentonite sulphur
