Abstract
- Resource depletion is one of the primary concerns of modern agriculture farmers, which needs to be considered for long term sustainability. To assess the effect of sesame stalk compost on the growth, yield, and quality of sesame under organic cultivation, long-term (four years) field experiments were conducted for eight seasons consecutively from 2020 to 2023. The inoculated composts collected after 90 days of composting contain N (1.45–1.50%), P (0.22–25%), K (0.23–0.25%), Fe (510–514 ppm), Zn (150–154 ppm), Cu (286–288 ppm), and Mn (540–542 ppm), which was higher than the uninoculated sesame stalk. Similarly, the humic acid content (122 mg/g of compost), fulvic acid (23–24 mg/g of compost), total humic substances (145–146 mg/g of compost), and CO2–C evolution (186–188 mg/100 g of compost) were significantly higher with microbial inoculated composts than uninoculated compost. The results of the long-term field experiment indicated that application of sesame stalk compost @ 5 t/ha significantly increased the soil organic carbon (6.30 g/kg), soil organic carbon (SOC) stock (11.8 mg/ha), raised the pH to neutralize the acidic pH in red lateritic soil (6.8 to 7.2), reduced the soil bulk density (1.38 to 1.34), penetration resistance (720 kpa to 630 kpa), and available N, P, and K. As a result, the sesame grain yield obtained with application of sesame stalk compost @ 5 t/ha (778–782 kg/ha) was comparable with recommended doses of chemical fertilizers (794 kg/ha). Significant improvement in grain quality (24.2% of protein, 418–422 ppm of Ca, 12.4–12.6 ppm of Zn, 9.6 ppm of Fe and 2.6 ppm of Cu) and oil yield (364.1–367.5 kg/ha) was also observed due to the application of microbial inoculated sesame stalk compost.
