Abstract:
The field experiment was conducted during the cropping season of 2024 at the Teaching and Research Farm, Department
of Crop Science, Faculty of Agriculture, University of Uyo. The aim was the production of Okra (Abelmoschus esculentus(L) as
affected by priming in Uyo, Nigeria. The farm is located on latitude 05°2` North and longitude 07°58`East, with an elevation of–52 m
above sea level. Mean annual rainfall of the area stands at about 2,500mm, with mean monthly relative humidity of 79.8%. Seeds of
lady finger, a variety of okra were obtained from the National Seeds Centre, National Root Crops Research Institute, Umudike, Abia
State for the experiment. The experimental treatments were four levels of priming: 0 (control), 12 hours, 24 hours and 36 hours. The
experiment was laid out in a Randomized Complete Block Design (RCBD), and replicated three (3) times. The experiment consisted
of four plots per replicate, totaling 12 plots for the entire experiment. The parameter measured during the research work are
germination percentage, plant height, leaf area, number of leaves, number of fruits, fruit length, fruit diameter, fruit weight and yield.
Each plot (flat) measured 2.25 m × 2.25 m. Each replicate was separated from one another by 1 m while plots were separated by 1 m
paths. The experiment consisted of four treatment factors as follows; Treatment A - (Control; 0 hours priming) Treatment B - (12
hours priming), Treatment C - (24 hours), Treatment D - (36 hours). The land which measured 13 m x 9.75 m was cleared with the aid
of machete and the trash packed to the borders of the farm. Significant difference (p<0.05) on both growth and yield parameters where
36 hours of priming recorded higher in both germination percentage (80.33), plant height (67.44), leaf area (311.59), number of leaves
(11.79), number of pod per plant (34.64), number of seeds (26.71), fruit length (12.11), fruit diameter (6.00), fruit weight (3.51), dry
pod weight (0.32) and yield 700.45). From the research finding, recommendation is hereby made for farmers within the locality, to
prime their okra seeds 36 hours before planting for fast germination and over-all yield.
