Melfert is the organic fertilizer that has been reported to supply a top quality organic matter and reclaim degraded soils. This study was carried out to evaluate the importance of the product for the seed cotton yield improvement. The experiment was conducted during 2018 main cropping season at Amibara District, Afar region, Ethiopia. The experiment comprised of seven treatments, and designed in randomized complete block design with four replications. Results showed that the mean seed cotton yield was significantly influenced by the application of Melfert organic fertilizer. Application of 1 t ha^-1 Melfert organic fertilizer alone or in combination with full or one-third of the recommended rate of N (46 kg ha^-1) produced significantly higher seed cotton yield (p<0.05) compared to the recommended nitrogen fertilizer level (46 kg ha^-1). However, application of SeaMel^pure organic fertilizer alone or in combination with Melfert or recommended N did not show positive effect on seed cotton yield. Despite the yield increment with the application of Melfert organic fertilizer alone or combined with full (reduced) dose of nitrogen fertilizer, application of 46 kg ha^-1 N, which is the existing recommendation, was still found economically feasible. Therefore, the new products could not be promoted as better management option for seed cotton production unless the cost is reduced and further investigation is advised.
