This journal is published twice a year (April and October). This journal is published online and in print. Open Science and Technology has the philosophy that this journal is open to anyone, including students, lecturers, researchers, consultants, and practitioners in the field of science and technology in general, to publish the results of their studies or research in this journal. This journal is also expected to become a fast-response journal, fast review, and fast publication. And in the future, it can be accredited nationally and indexed globally.

The treatments were organic fertilizers (goat manure, cow dung, and wood ash) and recommended dose of inorganic fertilizer (250 kg/ha NPK), and control (no soil amendment). The experiment was laid out in a randomized complete block design and replicated thrice. Soil, growth, and yield data were collected and subjected to analysis of variance. Significant means were compared with the least significant difference at 5% probability level.</p> <p><strong>Result:</strong> Results showed that cow dung had the highest organic matter content after harvesting, 2.55 and 2.43 % in 2021 and 2022, while the least organic matter content of 0.71% and 0.65 % was recorded in the control. Wood ash had significantly higher K levels after harvesting, while cow dung had the highest Ca. Goat manure had significantly higher Mg and Na than the other soil amendments. Treatment of NPK had significant fruit yield of 21.12 and 22.54 t/ha in both cropping seasons, respectively. The fruit yield recorded in goat manure was 20.23 and 20.81 t/ha in both cropping seasons, while 19.80 and 17.99 t/ha fruit yield were recorded in the wood ash treatment. The fruit yield obtained from NPK treatment was not significantly different when compared with yields obtained from goat manure and cow dung treatments. The least fruit yield, 5.12 and 6.03 t/ha in 2021 and 2022 was recorded in the control treatment.</p> <p><strong>Conclusion:</strong> Based on the study findings, the application of organic soil ameliorations (cow dung and goat manure) was recommended for higher fruit yields and sound soil conservation practices for sustainable crop production in an ultisol.</p> Angus Onwudiwe Ikeh, Helen Udoma Sampson, Maduabuchi Ekeoma Ukabiala, Nkechinyere Kate Anonaba, Juliana Nkiru Okamigbo, Chiamaka Gloria Akuwueze Copyright (c) 2025 Angus Onwudiwe Ikeh, Helen Udoma Sampson, Maduabuchi Ekeoma Ukabiala, Nkechinyere Kate Anonaba, Juliana Nkiru Okamigbo, Chiamaka Gloria Akuwueze https://creativecommons.org/licenses/by-sa/4.0/ https://www.opscitech.com/journal/article/view/146 Tue, 08 Apr 2025 00:00:00 +0700
