Aims: The aim of this study was to evaluate the performance of Annona muricata under four different treatments of organic manure in a screen house. Study Design: The study was laid out in a completely randomized design (CRD) with four replicates. Place and Duration of Study: The experiment was conducted in the Screen House of the Department of Forestry and Wildlife, Nnamdi Azikiwe University, Awka, Nigeria, from March to August 2018. Methodology: Four treatments of organic manure were applied to the seedlings of A. muricata, namely T1 (Topsoil + River sand (control)), T2 (sheep dung), T3 (decomposed sawdust) and T4 (cow dung). Data on plant height, leaf count, collar diameter, root length, and leaf area were collected and analyzed using analysis of variance and Duncan Multiple range test (DMRT) at 0.05 level of significance. Results: The results showed that all the growth parameters improved with increasing time. Plant height and leaf count were significantly higher in T4 with mean values of 11.79c ± 0.29 and 4.58b ± 0.22, respectively, and T1 (11.25 ± 0.26 cm and 4.58 ± 0.22 respectively) and lowest in T3 (9.01 ± 0.24 cm and 3.74 ± 0.18 respectively). Leaf area was higher in T4 (10.87 ± 0.43 cm2) and lowest in T2 (8.55 ± 0.35 cm2). Root length and collar diameter were highest in T3 (17.15 ± 0.53 cm and 0.25 ± 0.03 cm respectively), root length was least in T1 (12.93 ± 1.72 cm), while collar diameter was lowest in T2 (0.21 ± 0.00 cm). Conclusion: Cow dung potting media shows the greatest potential to promote robust vegetative growth of Annona muricata seedlings. Cow dung could be considered an accessible, affordable, and effective alternative to standard potting mixes for nursery propagation of A. muricata. These findings contribute valuable insights for optimizing plant growth practices in soursop cultivation.

The processes of mineralisation and immobilisation of nitrogen are defined, and the contribution of mass isotope (16N) studies to our knowledge of these simultaneous transformations in soil is briefly reviewed.Studies of immobilisation of nitrogen in soils treated with organic materials are reviewed with particular reference to the nitrogen content and carbon/nitrogen ratio of the added substances. Laboratory studies on carbon/nitrogen relationships in glasshouse soils incubated with mixtures of sucrose and inorganic nitrogen are summarised, together with comparative data for a wide range of other soils. The amounts of nitrogen immobilised in acid ' maiden ' soils on incubation with sucrose were increased by the addition of lime and phosphate, but did not reach the levels of activity of old glasshouse soils ; these findings are discussed in relation to the carbon/nitrogen ratios of the untreated soils and to their rates of evolution of carbon dioxide.Recent studies on the simultaneous mineralisation of carbon, nitrogen and phosphorus are briefly described. Data are presented for 32 soils showing relationships between initial soil pK and the percentages of the total soil nitrogen mineralised after liming or hydrolysed by autoclaving with acid. The observation that acid soils appear to contain a reserve of nitrogenous constituents which is readily mineralised on liming is discussed with reference to recent views on the chemistry of the nitrogenous components of soil organic matter.Reference is made to some recent work on laboratory incubation tests as a guide to the availability of soil nitrogen and the prediction of crop response to nitrogenous fertilisers.
