POULTRY MANURE

The proliferation of Urban Agriculture in sub-Saharan Africa is occurring due to the surging population, which has led to a demand for alternative crop cultivation methods. Consequently, there is a necessity to cultivate yams in containers as a means to enhance food security. Hence, a study was carried out to evaluate the effect of different combinations of garden soil and poultry manure potting media on the growth and yield of four cultivars of yam
(Dioscorea spp.). The study was carried out in containers (cement bags) in a field plot in Benin City, Nigeria. The treatments included: (i) garden soil alone (1:0), (ii) one part garden
soil and one part poultry manure (1:1), (iii) two parts garden soil and one part poultry manure (2:1), while four cultivars of yam including white yam (Ada Onitsha and Fakasa), water yam
and yellow yam were used. The experiment was a 3 × 4 factorial laid out as a Completely Randomized Design with three replicates. At nine weeks after planting, data was collected and recorded. At four months after planting harvest was done for only one cultivar (ada onitsha). The data collected was subjected to Analysis of Variance (ANOVA) to test the significance of the treatment means using Genstat Statistical Package. The results indicated that there were no significant differences observed in the growth characteristics of the different potting media. However, significant cultivar differences were observed in number of vines, leaf area, number of leaves, stem girth, and petiole length. The potting media treatments showed significant differences in tuber length, tuber girth, and tuber yield per bag with 2:1 garden soil and poultry manure producing the highest tuber yield per bag(1.47kg) while (1:1) and (1:0) produced (0.50kg) and (0.47kg) respectively. Therefore, the combination of garden soil and poultry manure with a ratio of 2:1 would be suitable for cultivating yam in containers

Yam (Dioscorea spp.) is a major staple crop in West Africa, particularly in Nigeria, where it serves as a vital source of food security, income, and cultural significance. Despite its importance, yam production faces numerous challenges, including declining soil fertility, high labor requirements in traditional mound cultivation, the prohibitive cost of inorganic fertilizers and security challenges across Nigeria. Bag propagation has emerged as an innovative alternative, enabling efficient soil and nutrient management, reduced pest and disease incidence, and suitability for limited land areas. Poultry manure, a nutrient-rich organic fertilizer, offers a sustainable means of enhancing soil fertility for yam production. It improves soil structure, microbial activity, and nutrient availability, thereby promoting vegetative growth and tuber yield. However, limited research exists on its application in bag-propagated yam. This study, therefore, evaluates the effect of poultry manure on the growth and yield of bag-propagated yam, aiming to identify a cost-effective and environmentally friendly practice that enhances productivity and supports sustainable yam cultivation. The experimental site was a private farm in Ogida quarters. The experiment comprised two treatments, each treatment had six (6) replications. At outset, date of planting was recorded. Number of days to sprouting, vine lengths, stem diameter, number of leaves were recorded at subsequent intervals. At harvest, tuber weight and vine weight were recorded. Data collected were analyzed using excel, the two means were compared using t-test method with the probability of 0.05 and unequal variance. Yam grown with poultry manure recorded higher vine length and greater tuber weight at harvest compared to those without manure. In conclusion, the study demonstrated that the application of poultry manure significantly improved the growth and yield of bag propagated yam.
