A field experiment was conducted to evaluate the effect of organic manures and industrial by-products on cane productivity. The soil type of experimental site was sandy loam. The treatments consisted of T1 - Seasoned pressmud @ 25 t ha−1, T2 - T1 + Lignite flyash @ 25 t ha−1, T3 - T1 + Vermicompost @ 5 t ha−1, T4 - Vermicompost @ 5 t ha−1 + Lignite flyash @ 25 t ha−1, T5 - Biocompost @ 5 t ha−1, T6 - T5 + Lignite flyash @ 25 t ha−1, T7 - FYM @ 10 t ha−1, T8 - NPK alone (RDF). The results revealed that yield attributes and cane yield improved in addition of organic manures and industrial by-products. The addition of integrating Vermicompost @ 5 t ha−1 + Seasoned Pressmud @ 25 t ha−1 along with RDF (T3) significantly recorded yield attributes of (125.83 × 1000) of millable cane ha−1, 2.57 cm of cane girth, 27.82 internodes cane-1, 1.37 kg of individual cane weight and cane yield of 165.18 t ha−1. It was observed that vermicompost, seasoned pressmud and chemical fertilizers enhanced yield attributes and yield of sugarcane.
