Effectiveness of Fungicides, Micronutrients and Botanicals on Various Cane and Soil Parameters for Managing Red Rot Disease of Sugarcane
摘要
A field experiment conducted during the 2020–2022 cropping seasons evaluated the impact of various fungicides, micronutrients, and botanicals on sugarcane germination, disease incidence, yield, plant growth, juice quality, and soil health. Among the eight treatments tested, the integrated application of seed treatment, drenching, and spraying with Carbendazim, combined with foliar application of boron and zinc (T1), recorded the best performance. This treatment significantly enhanced germination by 60.70%, reduced disease incidence by 80.56%, and increased yield by 67.49% compared to the untreated control. It also showed superior results in key growth parameters such as cane length, girth, weight, and the number of millable canes, alongside the highest juice quality with 20.22% Brix, 17.95% sucrose, and 88.80% purity. While T1 offered the maximum agronomic benefits, botanical treatments—particularly the combination of Neem and Tulsi (T7)—also demonstrated substantial improvements over control, including a 46.42% increase in yield and 54.23% reduction in disease incidence. Additionally, T6 (Tulsi) and T7 improved soil fertility by enhancing nutrient availability and maintaining favorable pH and electrical conductivity. These findings suggest that while chemical treatments are most effective for maximizing yield and crop health, botanical and bio-based treatments are promising eco-friendly alternatives with significant agronomic and soil health benefits.
