A completely randomized design was used, in a 2x5 factorial scheme, with two varieties of melon (V), namely: Goldmine and Imperial interacting with five concentrations of exhausted peat organic compound (C), that is: zero%; 3%; 6%; 13% and 25% and with four repetitions, totaling 40 plots or plastic vases.</p> <p><strong>Conclusion: </strong>It is recommended to use 15% exhausted peat compound in the composition of the substrate in the initial phase of the melon. The melon varieties showed similar responses in terms of exhausted peat compound concentrations.</p> 2020-05-27T00:00:00+00:00 ##submission.copyrightStatement## Compost Derived from Cattle Manure: Appropriate Organic Amendment for the Regeneration of Afzelia africana under Sudano-Guinean Climate of Adamawa Cameroon 2020-05-29T10:42:56+00:00 Lucien Tatchum Tchuenteu Bonaventure Kampete Marya Clautilde Megueni <p>Experiments in pots were conducted in order to establish appropriate technical route for regeneration of <em>Afzelia</em> <em>africana</em>, which becomes rare because of overexploitation in the Northern Cameroon. Study was conducted within campus of the University of Ngaoundere (Cameroon) from December 2017 to September 2018. A randomised experimental design with 04 treatments (control: unfertilized plant (T), compost derived from 100% cattle manure (CBV), compost derived from 100% poultry litter (CFP) and mixture 50% compost derived cattle manure with compost derived 50% poultry litter (MCBVFP)) was used. There were 45 plants per treatment. Seedling emergence rate and growth parameters (plant height, number of leaves per plant, diameter of stem at collar and total dry biomass of plant) were assessed, and 30 plants were sampled. Seedling emergence rates from treated pots by CBV, CFP and MCBVFP were 2.19, 1.81 and 1.31 respectively fold higher than that from unfertilized pots. There was a significant (p˂0.05) difference between compost qualities used relative to the growth parameters. CBV, CFP and MCBVFP encreased the total dry biomass of plants at 62.40%, 47.81%, 29.93% respectively compared to T. These results suggest that the origin and the quality of composting substrate was important not only for seedling emergence, but also for the growth of <em>A</em>. <em>africana</em>. We recommend the compost derived from 100% cattle manure for the regeneration of <em>A</em>. <em>africana</em> in the Nortern Cameroon.</p> 2020-05-29T00:00:00+00:00 ##submission.copyrightStatement##
