Aim: To investigate the early growth response of Morinda citrifolia to varying levels of Aleshinloye compost and N:P:K 15:15:15 in a degraded Alfisol in a tropical Nigerian environmental condition. Study Design: The study was laid out in a completely randomized design (CRD) with twelve (12) treatments replicated six (6) times with a total of seventy two (72) experimental units. Place and Duration of Study: The study was carried out in the greenhouse of Soil and tree Nutrition department of the Forestry Research Institute of Nigeria Ibadan (FRIN) and it lasted for a period of 6 month. Methodology: Degraded top soil used for the experiment was collected within FRIN arboretum. The soil was air dried and passed through a 2 mm diameter sieve before being filled into polythene pots of 15 cm x 20 cm dimension having a 3 kg soil capacity. The organic fertilizer was applied at 4 weeks before transplanting while the inorganic fertilizer was applied at 2 weeks after transplanting and pre-germinated seedlings of Noni were transplanted at four leaves stage. The data collected include Stem Girth (mm), plant height (cm) and Number of leaves starting from 30 Days After Transplanting (DAT). Results: The result revealed that the soil sample used for this study had pH value of 6.06 and the total N value of 0.11%. Noni plant with treatment T11 (N:P:K 15:15:15 at 80 Kg Nha-1 + Aleshiloye compost (AC) at 80 Kg Nha-1) had the highest plant height  values of 48.17, 65.67 and 77.87 cm respectively which are significantly higher (P = .05) than  T1 (control) with 37.17, 47.50 and 55.33 cm respectively that are the least values observed from 120 DAT to 180 DAT. The Plant Dry Matter (PDM) for leaves, stem and root (3.593, 2.720 and 4.220 g/plant) respectively from the control (T1) plant was the least when compared to every other treatment in the study. Conclusion: The use of composted manure in combination with N:P:K 15:15:15 ensured early and continuous supply of nutrient with resultant higher growth performance of Noni over a period of six months as shown in the study.

Background and Objective: Arbuscular Mycorrhizal Fungi (AMF) plays a role in the structural stability of soil which governs most soil activities. Stable organic manure such as compost may provide a suitable habitat and energy source for mycorrhizal growth, which is also a benefits in view of soil productivity. The impact of a combination of compost and mycorrhizal on plant growth was assessed in this study. Hence, experiment was conducted to investigate the influence of compost and mycorrhizalon the early growth response of Parkia biglobosa under a greenhouse condition. Materials and Methods: In the greenhouse of the Department of Bioscience, Forestry Research Institute of Nigeria. A 2 × 5 factorial experiment in a complete randomized design was conducted; two levels of mycorrhizal (with and without); five levels of compost (10t/ha, 20t/ha, 30t/ha, 40t/ha and no amendments) in two (2) kilogram soil under four (4) replications was set up. Laboratory analyses of soil and organic amendment incorporated in the soil were done. Data on growth variables were taken fortnightly. The data was statistically analyzed and mean were separated using Duncan Multiple Range Test (DMRT). Results: The results showed that, there was significant difference (p<0.05) in the plant height of Parkia biglobosa between mycorrhizal and non-mycorrhizal plants across all weeks after transplanting (WAT),compost application with the interaction of AMF at 40 t/harecorded the highest plant height and number of leaves at 16WAT with 35.14 cm  and 29.75 respectively, which are relatively comparable to other treatments used, the least plant height  and number of leaves were observed when -AMF 0 t/ha ( control) was used as an amendment with 23.00 cm and AMF 0t/ha (15.05) respectively. For collar diameter, all the treatments were comparable to one another except + AMF 30t/ha which produced the lowest collar diameter with mean value of 2.97mm. Conclusion: Based on the description of results above, it can be concluded that: The Inoculation of the AMF and compost significantly affect the early growth performance of Parkia biglobosa, thus providing optimum soil physical conditions for it growth.

Plants, unlike animals are naturally able to synthesize whatever compounds they need, require more than a dozen different elements [majorly Nitrogen, Phosphorus and Potassium (NPK)] as such. This study investigated the effect(s) of application of cow dung (CD) and NPK fertilizer on the early growth response of Irvingia gabonensis. Top soil samples of between 0 – 15 cm depth (control group I), top soil + NPK (Group II), top soil + cow dung (Group III) and top soil + NPK + cow dung (Group IV) were collected at varying combinations. The soils were then taken to the laboratory for physio-chemical analysis of key components [pH, N, P, K+, Ca2+, Mg2+, Na+, Org. C, sand, silt and clay]. Prior to and after actual experimentation, the N, P, K, Ca, Mg, Na, pH constituents of the cow dung were also analysed. For every two weeks (in twenty weeks duration) after application, plant heights, leaf area, number of leaf, stem girth were obtained and noted. By way of a sensitive weighing machine, 20 WAP destructive sampling was conducted to determine the weights of the shoot and root after oven-drying for three days in an oven sets at 75°C. In any case, these samples were then analysed for the nutrient content of the stem, root and leaf. Following data collection, comparisons of mean differences was performed using the Fishers protected least significant test and Duncan Multiple Range Test (DMRT) at 5% level of probability. Upon careful observation of result, study found that Irvingia gabonensis seedlings grown with cow-dung and NPK combination (Group IV) performed better in growth (height, diameter and leaf area) than seedlings grown in only top soil medium (TS) with single fertilizer use (Group II). However, NPK 3 CD 3, NPK 3 CD 2 and NPK 2 CD 3 best support the early growth phase of Irvingia gabonensis seedlings as compared to others. Study therefore showed Cow dung to contain substantial amount of essential elements that may be beneficial for the physio-chemical growth of Irvingia wombolu seedlings and combating reports of deforestations across the globe. It is recommended that for better results, cow-dung and NPK mixtures should be used than single use of the either treatments. Further studies aimed at corroborating this research are also recommended.

An experiment was conducted in the nursery of Department of Forestry Technology at the Federal College of Forestry Ibadan, Oyo state, Nigeria to determine the effect of organic and inorganic fertilizers on early growth response of Afzelia africana. Seedlings were collected from Forestry Research Institute of Nigeria, Ibadan, Oyo State and were transplanted into 2kg perforated polythene pots. The experiment was laid out in a completely randomized design with five treatments replicated three times. The treatments were: 20 t ha-1  water hyacinth compost (T1), 20 t ha-1  water hyacinth + poultry manure compost (T2), 20 t ha-1  poultry manure (T3) and 50 kg ha-1 NPK 20:10:10 (T4) and T5 - control (no fertilizer application). The compost was applied two (2) weeks before planting, while NPK 20:10:10 was applied two 2 weeks after planting. The experiment was monitored for eight (8) weeks after transplanting (WAT), while growth parameters were measured. The results of the study showed that application of fertilizers gave significant (p=0.05) increase in plant height (cm), stem diameter (mm), leaf production, and leaf area (cm2) of A. africana. Plant height ranged from 41.43 cm in the control to 47.96 cm in the pots where 20t ha-1 water hyacinth compost was applied. Stem diameter also increased across treatments, while leaf production ranged from 9 in the control treatment to 14 in the pots with 20t ha-1 poultry manure. These results suggested that the incorporation of organic and inorganic fertilizers increased productivity of A. africana. However, application of 20 t ha-1 water hyacinth compost is recommended because it is available, affordable and environmentally friendly for the production of A. africana especially in the study area.

The research work examined the effect of horse dung and pig dung on the early growth of Nauclea diderrichii seedling. The experiment was carried out at the back of library of Federal College of Forestry, Ibadan. The experiment consisted of five treatments which were replicated nine times in a completely Randomized design (CRD). The following materials were used: Topsoil, Polythenepot, seeds of Nauclea diderrichii, Horse dung and pig dung, sieve, wheel barrow, venier caliper, ruler, field record book and pen. Data on the number of stem girth, height, leave production and leave area were recorded fortnightly starting from a week after transplanting. The data collected were analyzed through Analysis of Variance (ANOVA). The result revealed that 15g of horse dung + 2kg of top soil had the  highest mean number of height value of 12.49cm followed by 10kg of horse dung +2kg of topsoil,(10.15cm). While topsoil only had the least mean number of height (8.25cm). The result further showed the highest mean stem girth (0.30cm) followed by 0.27cm and produced least mean stem girth of 0.24cm in treatments T12, T1 and T5 respectively. Also, in the leaf production the result revealed that 15g of horse dung +2kg of topsoil had the highest mean number of 16.69cm followed by treatment one 12,56cm and topsoil only produce the least mean leaf production of 9.40cm. The result further showed highest mean leave area (134.50cm2 ) followed by treatment one 124.60cm2 and (T5) produced the least mean leaf area of 108.06cm2. Analysis of variance (ANOVA) for plant height, stem girth, leaf production and leaf area also indicated that the treatment applied Nauclea diderrichii seedlings showed no significant effect. Generally 15g of horse dung + 2kg of topsoil produced the best result in terms of plant height, stem girth, leaf production and leave area of Nuclea diderrichii seedlings, hence treatment two (T2) is best suitable for raising Nuclea diderrichii seedlings.
