Effects of Accession and Nutrients sources of Rosselle Production (Hibiscus Sabdariffa L.) in Savanna Agro-ecological zone, Nigeria

The experiment aimed to evaluate the effect of Accession and nutrient sources on the growth and yield of sorrel grown at Makurdi during the 2023 Rainy Season. The treatments used were Accession (NG001, NG002 and NG003), Organic source (Poultry dropping, Cow dung, Goat manure and control) was used. The experiment is a 3 by 4 experiment laid in a randomized complete block design with three replications. The spacing of 20 x 75 cm was adapted for the work. During the investigation, some physiological variables, such as growth, plant height, the number of leaves, number of branches, number of flowers, days of maturity were measured. Other characters like number of calyx per plant, number of calyx per plant, calyx weight, plant weight and dry calyx weight and yield were also recorded. The results of the investigation revealed that sorrel generally responded to both varietal and nutrient source. All the parameters studies have significantly (P ≤ 0.05) responded to NG001, where it was observed to perform higher in both growth character such as plant height (60.23), the number of leaves (80.23), number of branches (7.81), number of flower (74.12), number of calyx per plant (54.63), number of seed per calyx (9.83), calyx weight (258.12), plant weight (582.50) and dry calyx (147.63) weight and yield (6.83) while NG003 had (130.00). On nutrient source poultry droppings was superior in both growth and yield related character such as, plant height (68.91), the number of leaves (88.31), number of branches (7.61), number of flower (73.23), number of calyx per plant (53.83), number of seed per calyx (8.03), calyx weight (257.23), plant weight (582.41) and dry calyx (146.83) weight and yield (6.03) while control plots had (135.22) days of maturity. Based on the results obtained it can be suggested that the use NG001 and poultry dropping will lead to optimum yield for roselle farmers in the study location.
