Nutrient Uptake and Quality of Sesame (Sesamum indicum L.) as Influenced by Sulphur and Boron

Abstract

At the Agronomy Field Unit, ZARS, UAS, GKVK, Bengaluru, a field experiment was carried out in kharif 2017 to examine the impact of sulphur and boron on sesame yield and quality (Sesamum indicum L.). Twelve treatments were reproduced three times in the experiment, which was set up using a factorial RCBD design. The application of the recommended dose of fertilisers (RDF) with 30 kg sulphur and 5 kg borax per ha resulted in significantly higher seed yield (470.00 kg ha-1) and stalk yield (3126 kg ha-1) than the application of the recommended dose of fertilisers with 40 and 5, 40 and 2.5, 30 and 5 kg sulphur and borax per ha (461.56 and 2826.67, 455.13 and 2733.33, 445.67 and 2626.67 kg per ha, respectively). Increased nutrient uptake of nitrogen (40.23 kg ha-1) phosphorus (15.01 kg ha-1) potassium (45.23 kg ha-1) sulphur (13 kg ha-1) and boron (162.4 ppm) was primarily responsible for increased seed and stalk yield. The application of the recommended dose of fertilisers with 40 kg sulphur and 5 kg borax per ha resulted in higher seed protein (10.72%). This matched RDF + 40 kg sulphur + 2.5 kg borax (10.66%). RDF+30 kg sulphur + 5 kg borax per ha produced the highest C: B ratio (3.5).
