Physico-chemical analytic comparison between normal compost, swift compost and PSN compost at Lawngtlai district, Mizoram

The present study was taken to compare the physical and chemical characteristics of three composts namely normal compost, swift compost and Phospho-sulpho-nitro (PSN) enriched compost during Rabi of 2023 at Krishi Vigyan Kendra Research farm, Lawngtlai district, Mizoram. The treatments consisted of T₀ Control (normal compost), T₁ (Swift compost) and T₃ (PSN enriched compost). The design followed was RBD and replicated thrice. The result revealed that there is no much physical difference among the three composting processes, however, the nutrients nitrogen and phosphorus content in PSN enriched compost was significantly higher than the other treatments with least CN ratio. Therefore, enriching compost by following Phospho-Sulpho-Nitro composting method could be recommended for farmer's practice.
