Abstract:

This study assessed the effect of acid scarification and organic manure on seed germination and early seedling growth of Vachellia nilotica. Seeds of V. nilotica were soaked in tetra-oxo-sulphate (vi) acid at 25%, 50%, 75%, and 98% concentration for 5, 10 and 15 minutes for each concentration respectively. After soaking, the seeds were removed, washed and rinsed in running tap water to remove the acid. Sixty seeds for each treatment and untreated seeds (control) were sown in a bowl previously filled with topsoil and watered for germination. Number of seeds germinated per day was monitored and recorded for each treatment. For early growth experiment, seedlings with relatively uniform height were selected from all the treatments and transplanted into polythene pots filled with topsoil amended with different organic manure viz: poultry dropping, cow dung, poultry dropping +cow dung and control. Watering was done once a day throughout the duration of the experiment. Growth parameters (i.e heights, stem diameter, number of leaves, and leave area) were measured over a period of 8 weeks. Results on germination showed that seeds treated with 98% acid concentration for 15 minutes had the lowest mean germination time (MGT) of 5.96 days and highest germination percentage (GP) of 51.7%, while results on seedling growth showed that soil amended with cow dung had the highest mean value of growth performance for all the parameters examined. It was recommended that soaking for 15minutes in 98% acid concentration should be adopted for optimum seed germination while cow dung should be used as organic manure.
