The field experiment was carried out at the teaching and research farm, Joseph Sarwuan Tarka University Makurdi, the experiment was to study the effect of organic manure on the growth and yield and the postharvest storage of fresh jute mallow in Makurdi. The experiment was laid out in a randomized complete block design (RCBD) replicated three times and the treatments were poultry droppings, cow-dung, goat dung and control. The data were observed and collected from growth parameters on leaf length, numbers of branches, leaf area, leave weight and yield for analysis. Data collected was subjected to analysis of variance (ANOVA) using GENSTAT statistical software version 17.1DE (2015) and significant means were separated using fisher's least significant differences at 5% level of probability. Significant differences (P<0.05) were observed among the organic manure for all parameters both for growth and yield. Poultry droppings, cow dung, goat dung and control from the result obtained, poultry droppings had the highest growth parameters on plant height (23.70) leaf length (5.01), numbers of branches (14.00), leaf area (66.50), leave weight (0.41) and yield (0.0727) kg/ha while control had the least increase and on weight lost and decay tray had the highest with (10.25) and (14.94) respectively. I therefore recommend the application of poultry droppings at 15t/ha for jute mallow production which gave the highest value of 0.0727 kg/ha. Jute mallow was protected from microbial assault and spoiling for eight days while maintaining its color and other physicochemical characteristics by treatments applied at a tropical ambient temperature of 30 ± 2°C and a liter of water.
