Abstract:
A field experiment was carried out at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari (Gujarat) during the rabi seasons of 2021–2022 and 2022–2023 to investigate the impact of biogas slurry on sugarcane growth under south Gujarat conditions. The treatments, viz., T₁: 100% RDF + 10 t/ha biocompost; T₂: STCR-based fertilizer + 2.5 t/ha LBGS (liquid biogas slurry); T₃: soil test-based fertilizer + 2.5 t/ha LBGS (liquid biogas slurry); T₄: 100% RDF + 2.5 t/ha LBGS (liquid biogas slurry); T₅: 100% RDF + 5 t/ha LBGS (liquid Biogas slurry); T₆: 100% RDF + 7.5 t/ha LBGS (liquid Biogas slurry); and T₇: 100% RDF + 10 t/ha LBGS (liquid Biogas slurry) were applied to the sugarcane crop in the rabi season and replicated four times in randomised block design. Germination percentage at 30 DAP and 45 DAP as influenced by different treatments did not exert any significant effect during both the years of experimentation and the pooled study. Tillers per plant at 180 DAP, numbers of internodes per cane and cane girth were not significantly affected due to different treatments at harvest during individual years and in pooled analysis.
