Okra plays an important role in human diet, medicine and industrialization. However, productivity is low due mainly to the use of unimproved cultivar and low native soil fertility among others. This study was conducted in 2020 and 2021 raining seasons at the Teaching and Research Farm of Faculty of Agriculture and Life Sciences, Federal University Wukari, Taraba State, Nigeria to evaluate the effect of cattle manure rates on growth and yield of okra varieties. The treatments involved three varieties of okra (local, Clemson and Basanti 447) and four rates of cattle manure (0, 15, 20 and 25 t ha-1) laid out in 3 x 4 factorial arrangement fitted into a randomized complete block design (RCBD) and replicated three times. Data were collected on growth characters (plant height, stem girth and number of leaves) and fruit yield (number of fresh okra and weight of fresh fruit). The results obtained showed that growth characters varied among varieties. Taller plants were observed in Clemson and Local than in Basanti 447. Plants emerging from Clemson had the thickest stem and highest number of leaves. Cattle manure application influenced growth characters positively as plants without its treatment had the lowest plant height, stem girth and number of leaves values. The tallest and highest numbers of leaves were observed on plants which received 25 t ha-1 of cattle manure. Plants which received 25 t ha-1 of cattle manure also produced the thickest stems but comparable with 20 t ha-1 cattle manure fertilized plants. Basanti 447 plants had the highest fruit yield components but not significantly higher than those of Clemson plants. Plants supplied with 25 t ha-1 of cattle manure had the highest number of fruit, heaviest fruit weight and yield but at par with plants which were fertilized with cattle manure at the rate of 20 t ha-1. Clemson variety treated with 20 t ha-1 of cattle manure are hereby suggested for farmers in Wukari area of Taraba State for profit maximization and sustainable production of okra.
