Prior integration of any tree/shrub species in a given land use system, there is always the need of undertaking a field trials to assess their adaptability and growth performance under a particular environment. Study was planned and conducted to evaluate the adaptability potential and growth performance of six nitrogen fixing tree/shrub species in Dello-menna district of Bale zone, southeast Ethiopia. The considered species in the study are Cajanus cajan, Flemingia macrophylla, Gliricidia sepium, Sesbania sesban, Calliandra calothyrsus, and Leucaena leucocephela. Seedlings were produced in a nursery site and transplanted to the experimental site. The experiment was laid out in RCBD design with three replications, and the management practices employed uniformly for each species throughout the stud period. In the study the necessary growth performance data parameters; plant height, root collar diameter and survival rate were measured and recorded. Thereafter, the data was analysed by GenStat (15th ed) and Excel computerized programs. Results obtained showed that, these growth performance data parameters were significantly (p < 0.05) varied among the tested species. In this respect, F. macrophylla, S. sesban, G. sepium and C. cajan attained the higher mean values in survival rate, plant height and root collar diameter. While L. leucocephela and C. calothyrsus attained the lowest mean values for the entire growth performance parameters. Hence, it can be inferred that the study site matched well with the environmental requirement of F. macrophylla, S. sesban, G. sepium and C. cajan. The species therefore offers much promise for future use in any of agroforestry practices in the area. However, evaluation of their contribution to soil fertility improvement and crop yield needs to be further investigated as this may insights to know their nutrient provision potential while integrated together with annual and/or perennial plants in agroforestry land use system.

Background. Lowland Bamboo (O. abyssinica) is an indigenous multipurpose species in Ethiopia and endemic to Africa.Aims. The present study was aimed at investigating provenance variation on early survival rate and growth performance ofO. abyssinicaseedlings so as to obtain suitable provenance for production of high quality seedlings.Methods. Seeds were collected from Pawe and Sherkole districts. Following raise of seedlings data on survival count, culm height, root collar diameter (RCD), number of leaves, and biomass were recorded.Results. Pawe provenance had slightly higher survival rate (91%). Except seedlings RCD, rhizomes length, and roots fresh and dry weights, higher mean values of other morphological parameters were recorded in Sherkole provenance. Biomass of leaves and culms was higher in Shekole provenance, while root biomass was exceeded by the Pawe provenance. However, significant variations (P<0.05) between provenances were observed in RCD, rhizomes length, weight of fresh culms, and fresh and dry root system. Seedlings growth parameters (height and RCD) were positively and significantly correlated with Biomass variables and hence could be considered as better evaluation criteria for seedling quality at green house.Conclusion. Sherkole provenance should be considered for raisingO. abyssinicaseedlings at green house.

We measured the initial growth performance of a young plantation of European beech treated with a brassinosteroid compound prior to planting and compared it with a control treatment: we assessed heights, root collar diameters and mortality rate during the period 2012–2015. The trees showed posterior damage by ground frost after a substantial late frost event on the night of 4–5 May 2014. Therefore, we evaluated the post-stress vitality of trees, subsequent height increment from spring to August, and the height range of the damage.<br />Mean height, root collar diameter, and mortality rate did not show any significantly better performance in the brassinosteroid treatment over the control treatment. Neither did the application treatment have a significant positive effect on the resistance of beech to late frosts. The severe frost damage was most intense at 30 cm above ground, and rapidly declined with increased height.

The effect of stocking density on growth performance and survival rate of endangered Labeo bata, was conducted in nursery ponds from 14th June to 13th August, 2013. Three different stocking densities viz. 500, 600 and 700 piece-1 decimal were assigned as treatment T1, T2 and T3, respectively. The initial average weight of L. bata was 0.15±008 g. Hatchlings in all the nursery ponds were fed indigenous feed (26.95% crude protein) for 8 weeks. Temperature, ammonia nitrogen, pH had no significant differences (P<0.05). Final weight (g) was found to be the highest (4.06±0.06) in T1 and the lowest (3.20±0.03) in T3. The mean values of weight gain (g) was the highest (3.91±0.06) in T1 and the lowest (3.05±0.03) in T3. SGR was highest (5.49±0.02) in T1 and lowest (5.09±0.02) in T3. Yet again, survival rate was highest (70.33±0.88) in T1 where stocking density was the lowest among those aforementioned three treatments and lowest (61.00±0.58) in T3 where the stocking density was the highest among the treatments. And finally production (kg-1ha) was found highest (352.66±4.42) in T1 and lowest (337.50±3.19) in T3. Rearing of the Labeo bata fry in those three different stocking densities showed significant (p<0.05) variation both in highest survival and growth performance. Overall production of L. bata in treatment T1 was significantly higher than that of the other two treatments T2 and T3. Despite of this, consistently higher CBR was found from treatments T1 (1:1.78) than from treatment T2 (1:1.25) and T3 (1:1.06).J. Environ. Sci. & Natural Resources, 9(1): 67-73 2016

Khaya ivorensis A. Chev. (African mahogany) is one of the most economically important forest species, since it is used in the international furniture market. However, little is known about its culture and nutritional requirements. This study aimed to assess the development of K. ivorensis plants subjected to different base saturations, as well as to different N, P and K levels. An 8-ha area was used, wherein 4 ha had base saturation increased to 55% and the remaining 4 ha to 75%. The experimental design adopted was randomized blocks with eight repetitions in a factorial scheme (4 × 4 × 4), being four N doses, four P doses and four K doses. The base saturation was assessed through the block effect. The root collar diameter and the plant height were measured 12 months after planting. Each experimental plot comprised six plants. The root collar diameter showed statistical differences between blocks and N doses. Only the NPK association showed statistical variation in plant height. However, a growth decreasing trend resulting from increased N doses was observed, as well as a growth increasing trend resulting from increased P and K doses. All treatments favored African mahogany growth. The most indicated base saturation was 55%, since there was no plant growth improvement when V% was increased to 75%. The excess of N impaired the growth of the species. The best treatment comprised 60 g urea, 240 g triple superphosphate, and 168 g potassium chloride.

Scots pine (Pinus sylvestris) is an economically important source of timber in Mongolia and has been widely used in reforestation programs. In this study, we investigated the effects of mycorrhizas on the growth of pine (Pinus sylvestris) seedlings. Inoculation with ectomycorrhizas and endomycorrhizas increased the height, root length, and root collar diameter of the pine seedlings compared to the non-inoculated seedlings. Furthermore, the results of the study showed that the percentage survival rate is higher in mycorrhizal inoculated pine seedlings than control seedlings. These results demonstrated that inoculation could effectively form ectomycorrhizas with pine seedlings and promote its growth, which can be used to restore Mongolian forest.

ABSTRACT The use of organic fertilizers can increase the production of forest species for the extraction of wood from monoculture stands or integrated systems. This study aimed to evaluate the effect of applying doses of sheep manure on the biometric traits of Mimosa caesalpiniifolia (‘sabiá’) in a silviculture system in an area previously occupied by native degraded pasture in an Albaquult. The experimental design was randomized blocks with four repetitions, with treatments corresponding to five doses of sheep manure per plant: 0, 2, 4, 8, and 12 kg in the first year, while in the second year the double of the doses (0, 4, 8, 16 and 32 kg per plant) were applied as topdressing under the canopy. The following biometric variables were evaluated: height (H); root collar diameter (RCD); diameter at breast height (DBH); above-ground dry weight (AGDW); accumulation of nutrients (aerial part); and soil fertility. The plants were responsive to the organic fertilization regarding the variables H, DBH, and AGDW. The sheep manure increased the mean values of pH, P, K, Ca, Mg, SB, CEC, BS, S-SO4 2- and Zn, and reduced the potential acidity in the 0-0.20 m soil layer. The organic matter variable increased up to the dose of 13.70 kg per plant. The accumulation rates of macro and micronutrients in the ‘sabiá’ plants were N > Ca > K > Mg > P > S and Fe > Mn > B > Zn > Cu, respectively.

The survival and growth of ectomycorrhizal and ectendomycorrhizal red pine (Pinus resinosa Ait.) seedlings transplanted from a nursery onto iron tailings were examined. Seedlings were inoculated with the E-strain fungus BDG-58 (Complexipes sp. Walker emend. Yang & Korf), Phialophora finlandia Wang & Wilcox, Pisolithus tinctorius (Pers.) Coker & Couch, or Suillus subluteus (Peck) Snell ex Slipp & Snell. The first two isolates are ectendomycorrhizal fungi and the last two ectomycorrhizal fungi. Two-year field data on the tailings indicated a mycorrhizal treatment effect only in root-collar diameter at the end of the first growing season. The mycorrhizal treatments had a higher survival rate than the controls, with BDG-58 and Ph. finlandia seedlings having the greatest percent survival. Results from freehand root sections indicated that ectendomycorrhizae persisted in young roots of 4-year-old red pine seedlings that had been transplanted 2 years previously.

Declining soil fertility is a main reason for the slow growth in food production in Africa. However, the practices of incorporating fertilizers could potentially improve soil fertility and productivity. This experiment was carried out to determine the efficacy of inorganic fertilizer on the early growth performance of Vitellaria paradoxa under a greenhouse condition set up at the Department of Forestry Technology, Federal College of Forestry Ibadan, located within the Government Reserve Area (GRA) Jericho Ibadan. The treatments included two fertilizer types, (Urea and NPK 15:15:15) at different concentration levels which were; Urea at three (3) levels; 50 mg kg1, 100 mg kg1and 150 mg kg1: NPK (15:15:15) at three levels; 50 mg kg1, 100 mg kg1 and 150 mg kg1, combination of Urea + NPK and Control (no application). The results showed that application of inorganic fertilizer at any rate produced higher growth in plant height and collar diameter than the control experiment. Application of different rates of fertilizer on leaf production was comparable with the control experiment. Though, there was no appreciable variation in all fertilizer rates, the highest value was obtained with the combination of NPK and urea at 150/100 mg kg1 for plant height, leaf production and leaf area while the application of NPK/Urea: 150/150 mg kg1 produced the highest collar diameter. From this study, nutrient supply from NPK and Urea could help enhance the growth performance of Vitellaria paradoxa seedlings and help improve the mass propagation of target species in the nursery. Further studies are recommended to validate the optimum fertilizer requirements of the plant species.
