Effect of composts and industrial by-products on yield and yield attributes of sugarcane
Field experiment were conducted in sandy loam soil at Mamangalam Village at Chidambaram Taluk, Cuddalore district, Tamil Nadu. The soils of Mamangalam was classified as Ultic hapludalfs comes under Pattukottai series having sandy loam texture, the available nutrient status was low in N, medium in P and low in K. In plant crop experiment, treatments consisted of main plot treatments M1 –Control, M2 – Farmyard Manure (FYM) @ 25 t ha-1, M3 – Seasoned Pressmud (SPM) @ 25 t ha-1, M4 – Biocompost (BC) @ 5 t ha-1. The sub plot treatments were S1-100% recommended dose of fertilizers (N, P, K @ 275; 62.5; 112.5 kg ha-1) S2 – S1 + Lignite Flyash (LFA) @ 25 t ha-1 S3 – S1 + Humic acid (HA) @ 50 kg ha-1. S4-S2 + Humic acid (HA) @ 50 kg ha-1. The design followed was split plot design. The treatments were replicated thrice. The yield attributes and cane yield (t ha-1) also was recorded.
