Effect of dumpsite organic manure soil on growth, nutrient content, and yield of Curcuma longa L.(turmeric) in Owerri, Imo State

Curcuma longa L.(turmeric) is one of the most essential available spices in Nigeria. The field study was conducted at Teaching and Research Farm of Faculty of Agriculture and Veterinary Medicine, Imo State University, Owerri, Nigeria. During the planting season of 2019 to assess effect of different levels of Dumpsite Organic Manure Soil on Growth parameters, nutrient content and yield of turmeric. The experiment was laid in Randomized Block Complete Design with three replications. T­1: Control, T2: 05 tons; T3 10 tons, T4: 15 tons of Dumpsite Organic Manure Soil. The result of the study revealed that high doses (T­4­) of Dumpsite soil significantly influenced maximum growth parameters viz; plant height, leaf area, leaf length, leaf area index.15 tons of Dumpsite Organic Manure Soil (T4) recorded the maximum yield per hectare (17.66kg/h) while the lowest (6.863kg) was obtained from control. The result of proximate composition showed that 15 tons (T4) of dumpsite organic manure soil significantly improve the Ash, Fibre, Protein and carbohydrate contents compare to control. Moisture content (81%) and fat content (0.6369%) were higher in control compare to other treatment levels. The result has shown that Dumpsite Organic Manure Soil has potential to improve growth of Turmeric (Curcuma longa L.) and other crops
