The seeds were subjected to 7 treatments which include cow dung and poultry manures and topsoil only as control treatment. The seeds were sown directly into the polythene pots thoroughly mixed with the organic manures at different levels of application which includes 2.5 g, 5.0 g and 10.0 g with 3 replicates making a total of 21 poly pots. The germination was thoroughly observed for 3 weeks after planting. The experiment was laid in a completely Randomized design with 3 replicates.</p> <p>The parameters assessed were the plant height, the number of leaves and stem girth. The data collected were subjected to ANOVA.</p> <p>The Results of the study showed that treatment T1 with cow dung at 2.5 g had the highest plant height of (49.65 cm), stem diameter of (0.458 m) and Number of leaves (12.27) followed by T5 (5.0g of poultry Manure) with plant height of (45.40 cm) stem diameter (0.435 cm) and number of leaves (12.73). Treatment 7 which is the control treatment had the Least Leaf Number of (24), height of (28.97) and stem diameter of (0.257).</p> <p>Therefore from all the treatments used, cow dung at 2.5 g and poultry manure at 5.0 g are advisable for Raising <em>Zingiber officinale</em>.</p> O.

In Cameroon, it is the main food of the population of the Sudano-Sahelian zone. Its production could decline by up to 20% by the middle of the century, due to climatic disturbances. This climatic disturbance in Cameroon has led to several consequences among which, low crop yields. The comparative effect of the biological fixation of nitrogen and chemical fertilizer on the optimization of yield of two varieties of Sorghum, was conducted from July to October at IRAD (Institute of Agricultural Research for Development) station of Foumbot. The experimental design was a complete randomized block with two factors: varieties of sorghum (V1: S35 and V2: BIOGLOR) and treatments (T<sub>0</sub>: Control, T<sub>1</sub>: 20-10-10 and T<sub>2</sub>: Sorghum / NITU beans). The collar diameter, the number of leaves and plant height were evaluated each week and yield in the end of the cropping season. As a result, treatment T<sub>1</sub> induced very significantly (P ˂ .01) growth (shoot length, leaf and collar diameter). T<sub>1</sub> (V1: 1.30 ± 0.11 t.ha<sup>-1</sup>, V2: 2.01 ± 0.07 t.ha<sup>-1</sup>) and T<sub>2</sub> (V1: 1.12 ± 0.02 t.ha<sup>-1</sup>, V2: 2.15 ± 0.03 t.ha<sup>-1</sup>) showed statistically equal yields, and significantly different from T<sub>0</sub> (V1: 0.50 ± 0.06 t.ha<sup>-1</sup>, V2: 0.55 ± 0.05 t.ha<sup>-1</sup>). The BIOGLOR variety had the highest yield (1.57 ± 0.57 t.ha<sup>-1</sup>) compared to the S35 variety (0.97 ± 0.19 t.ha<sup>-1</sup>). The treatment T<sub>2</sub> is the recommended fertilizer system because of the higher grain yield of sorghum and its ability to protect the environment.</p> Stephane Martial Kamtchoum, Ibrahim Nchoutnji, Carine Nono Temegne, Libert Brice Tonfack, Lucas Fofe, Thierry Gaitan Tchuenga Seutchueng, Christelle Mbieji Kemayou, Frank Kamdem Notche, Christopher Suh, Emmanuel Youmbi ##submission.copyrightStatement## Thu, 12 Sep 2019 00:00:00 +0000 Assessing Seed Vigor Characters of Selected Rice (Oryza sativa L.) Genotypes Using Accelerated Ageing Method <p>Rice (<em>Oryza sativa</em> L.) is an annual grass with the third-highest world production after sugarcane and maize. However, due to losses in vigor caused by poor seed storage, global consumption has surpassed production. Preservation of germ plasma both in-situ and ex-situ is the key to the conservation of rich biodiversity. Seed vigor is a key element of seed quality and high vigor seeds give uniform plants stand and higher yields per area. Accelerated ageing tests enable testing the vigor of stored seeds by subjecting the seeds to a particular temperature and relative humidity over time and then performing standard germination tests. Viability of most seeds normally reduces with the storage period, storage temperature and relative humidity. There is limited information on the duration of storage for rice seeds. Accelerated ageing is considered an excellent option as a vigor test when compared to seedling emergence and index of emergence speed because of the shortest time of acquisition and efficient results. Accelerated ageing tests at 0, 24, 48 and 72 hours (45ºC and 98% RH) were carried out JKUAT post-harvest laboratory using eight rice varieties’ in four replications of 100 seeds each. Data were analyzed using GENSTAT statistical package. ANOVA and T-tests at 5% significant level. Results showed that there was significant variation in both coleorhiza and coleoptile formation among rice varieties (p&lt;0.001), treatments (p&lt;0.001) and interaction between rice varieties and treatment (p&lt;0.001). The difference between all treatments was significant with 72 hours’ treatment having the highest number of days to coleorhiza and coleoptile formation. The present study has shown that prolonged duration of higher temperatures results in a reduction of seed viability. The earliest coleorhiza formation was observed on day 2 and the latest on day 6. Results from this study will guide farmers and seed processors on considerations regarding storage period and storage temperature to ensure high-quality seeds.</p> S. A. Henga, W. M.
