Item Open Access ASSESSMENT OF GERMINATION AND EARLY GROWTH TRIAL OF Gmelina arborea (ROXB.)(Department of Forestry, Nasarawa State University Keffi., 2015-09-26) Egbewole, Z.T.; Elabora, A. A.; Akinyemi, O.The Gmelina arborea is a multi-purpose tree used daily by the forest industries for pulping, light constructions, furniture's and rural communities as fuel wood. a field experiment was carried out to investigate the provenance germination and early growth trial of Gmelina seedlingd. one thousand eight hundred seeds were sourced from 3 different locations namely Akwanga, Nasarawa Eggon and Lafia for germination tests, while 270 seedlings were examined for growth performance. The study was laid in a 3 x 3 factorial experiment in a completely randomnized design, Analysis of Variance was performed to show the the comparative performance of each treatment. Duncan's Multiple Range test (DMRT) was applied to locate where the significant difference occur among the locations and treatments in the measured variables. The result of germination with respect to locations revealed that Akwanga recorded the highest germination percentage of 70.09+- 25.70%, Nasarawa Eggon 66.90 +- 25.24% and Lafia 64.04 +- 22.20%. Also with respect to treatment ,it revealed that( T2- Sundried for 72hrs and soaked in water for 72hrs) recorded the highest germination with 66.61+22.33* uud (T3,Control, 65M±27.24*.

GAERTN(Department of Forestry, Nasarawa State University, Keffi., 2014-01-01) Egbewole, Z.T.; Kuje, E. D.; Akinyemi, O.Item Open Access TECHNICAL EFFICIENCY OF RATTAN-BASED ENTERPRISES IN SOUTH WESTERN NIGERIA(Department of Forestry, Nasarawa State University Keffi., 2014-09-26) Akinyemi, O.; Oluwalana, S.A.; Momoh, S.; Aduradola, M.; Egbewole, Z.T.The study examined the technical efficiency of rattan-based enterprises in South Western Nigeria. Multistage Sampling technique was adopted to select 121 rattan cane processors in Lagos, Ogun and Oyo States and data were collected through administration of structure questionnaire. Stochastic Frontier production function was used to estimate the technical efficiency of rattan-based enterprises. The result of the maximum likelihood estimate of the stochastic Frontier showed that sigma (S = 0.979) and the gamma (Z = 0.183) were statistically significant at 1% probability level. The estimated gamma value indicated that about 18.3% of the variability in output was not explained by the selected explanatory variables. Findings showed that land area occupied by the enterprise and capital were statistically significant respectively (P<0.05). The technical efficiency indices ranged from 0.67 and 0.98 with a mean of 0.85 implying S5% efficiency level. Education and gender were important determinants of technical efficiency (P<0.05) in rattan-based enterprise. The study recommends the need for upgrading the skills and developing the processing capacity of rattan-based enterprises.
