Abstract
This study investigated the effect of sowing media on the seed germination and subsequent seedling growth of Senna fistula L. Treatments were T1 (Top soil), T2 (River sand), T3 (Grinded coconut husk) and T4 (weathered sawdust), replicated two times for seed germination. The treatments were arranged in a Completely Randomized Design (CRD) and the data generated was subjected to analysis of variance (ANOVA) at 5% level of significance, while mean separation where appropriate was done using Least Significant Difference (LSD). The different sowing media used had positive effect on the seed emergence, the seeds planted in river sand had the highest emergence percentage of 70%. The different sowing media used did not have any significant effect on the vegetative growth parameters, statistically, they had same effect on the parameters measured. Nonetheless, seedlings from river sand produced highest number of leave (20.4), seedlings from topsoil produced highest plant height and largest leaf area of l0.62 cm and 37.l4 cm2 respectively. The seedlings from weathered sawdust produced the highest stem diameter of 0.79 mm, while seedlings from grinded coconut husk had lowest values for all the growth parameters measured. Therefore, it is recommended that river sand or weathered sawdust can be used to propagate Senna fistula seeds.
Highlights
Effect of Different Sowing Media on Seed Germination and Seedling Growth of (Golden Shower Tree) Senna fistula L
The top soil used was collected from the College premises, the grinded coconut husk was collected at a nearby coconut market (Ogunpa market), and the weathered-sawdust was collected from Forestry Research Institute of Nigeria (FRIN), while the river sand was collected from stream within the college
It was removed from the capsule and airdried and the seed boxes was filled with different sowing media such as top soil, river sand, grinded coconut husk, and weathered saw dust respectively, thirty (30) seeds of Senna Fistua L. was sown and watered
Summary
The experiment was carried out at Federal College of Forestry Farm Practical Experimental site, Jericho Hill Ibadan, Oyo State, Nigeria. Seed of Senna fistula L. was collected at Federal College of Forestry, Jericho Hill, Ibadan, Oyo State, Nigeria. The top soil used was collected from the College premises, the grinded coconut husk was collected at a nearby coconut market (Ogunpa market), and the weathered-sawdust was collected from Forestry Research Institute of Nigeria (FRIN), while the river sand was collected from stream within the college. The seed of Senna fistula L. was harvested from a mother tree It was removed from the capsule and airdried and the seed boxes was filled with different sowing media such as top soil, river sand, grinded coconut husk, and weathered saw dust respectively, thirty (30) seeds of Senna Fistua L. was sown and watered. Data collection: Data was collected on the following parameters: Emergence Percentage: this was the total number of seedling emergence over total number of seed planted multiply by 100: Total number of seedling emergence
