Sesame, traditionally grown in low-input systems, has been modernized and mechanized due to breeding advancements. However, there is a lack of research on fertilization needs for both modern and traditional agricultural systems. A field experiment was conducted to study the impact of organic manure and inorganic fertilizer on the growth, yield, and quality of sesame during the Kharif season of 2022. The experiment was laid out in randomized block design (RBD) with ten treatment combinations viz., T1, Control; T2, 25% N through pig manure + 75% RDN (recommended dose of nitrogen); T3, 25% N through poultry manure+75% RDN; T4, 25% N through FYM + 75% RDN; T5, 25% N through vermicompost+75% RDN; T6, 50% N through pig manure + 50% RDN; T7, 50% N through Poultry manure + 50% RDN; T8, 50% N through FYM + 50% RDN; T9, 50% N through Vermicompost + 50% RDN; T10, 100% RDN which were replicated thrice. The results indicated that maximum plant height at 90 days after sowing (DAS) and at harvest stage was noticed under T10 as compared to the other treatments, respectively. At 70 DAS, significant maximum number of branches per plant and 60 DAS highest leaf area index (LAI) was recorded under T10. Similarly, treatment T10 resulted the highest value of crop growth rate (CGR) and relative growth rate (RGR) at 60 DAS as compared to the control plot. As compared to the T1, significantly higher number of capsules/plant and length of capsule was recorded under T10 followed by T3 and lowest was observed under control (T1). The seed yield and stover yield significantly maximum observed in treatment T10 (100% RDN) but this treatment at par with treatment T3 (25%N through poultry manure+75%RDN). Control (T1) treatment recorded the minimum seed yield and stover yield. In case of quality parameters, maximum value of oil yield and protein content was recorded under T10 as compared to the control plot. However, due to the highest yield obtained under treatment T10, followed by T3, resulting in the highest B:C ratio of 2.60 and 2.17, respectively.
