Abstract: A study was conducted to assess the role of tiller height on quality production of palma rosa grass varieties. A field experiment which contains two varieties (Wg-tejisar-I and Wg-tejisar-II) and four levels of cutting height (20, 25, 30 and 35 cm) in RCBD with three replications. There was tow harvesting time with in three months interval all parameters were taken during the course of field experiments. The first cycle data was taken three months later after planting. Even if no significant difference the effects of planting 20 and 35 cm height tiller on the two palmarosa verities have better plant height, number of leaves, number of tillers. The maximum weight of fresh biomass was harvested by planting WG-Tejsar-II variety with 20 cm long tillers (8.89 t/ha) which have no biomass difference with planting WG-Tejsar-I 20 cm long tillers (8.60 t/ha). The highest oil content recorded at the plot which contain WG-Tejsar-I variety with planting 30 long tillers (1.90%) and planting WG-Tejsar-II variety with 35 cm long tillers (1.29%) ranked first and second respectively. The recorded oil yield of planting 20 cm long tillers on the WG-Tejsar-I (109.92 kg/ha) and 35 cm with WG-Tejsar-II (90.44 kg/ha) verities have higher essential oil as compare to planting 25 and 30 cm long tillers respectively. Excluding plant height and survival count all parameters were affected by varying the height of tillers in the time of the two cycle and the value indicated that planting 30 or 35 long tillers for the two palmarosa variety shows a good result in the second cycle relative to the rest of configured height levels. In conclusion planting 20 and 35 cm long tiller had good effect in all physical and quality parameter in the first cycle. Due to small increment of the value of each parameter in the second cycle at 30 and 35 cm long tiller as compare to the first cycle, planting WG-Tejsar-I with 20 cm or WG-Tejsar-II with 35 cm tiller long contribute good palmarosa production.

Abstract: Potato (Solanum tuberosum L.) is an important food and export crop in central highlands of Oromia region. The limiting macro and micronutrients were identified for the production of potato crops in Boneya districts. The rates of these nutrients for high potato yield and disease resistance are not yet determined. Therefore, this research was conducted to determine the effect of blended NPSB fertilizer rates on yield and yield related traits of potato varieties at Boneya Kebele, central highlands of Oromia region. The experiment was conducted as factorial combination of seven levels of blended NPSB fertilizer rates (0, 50, 100, 150, 200, 250, 300 kg ha-1) and three potato varieties (Belete, Gudane and Jalane) in Randomized Complete Block Design with three replications. The results of the study revealed that variety and blended NPSB fertilizer had significant effect on crop phenology, growth, tuber yield and yield components except proportion of medium size tubers which is not influenced by the two main factors. Blended NPSB fertilizer had nonsignificant effect on days to 50% emergence, number of main stem/hill and proportion of large size tubers. Variety and blended NPSB fertilizer interacted to influence days to 50% flowering, average tuber weight (g), average tuber number, unmarketable tuber yield, and proportion of small, medium and large size tubers. The highest marketable tuber yield (30.74 t ha-1) and total tuber yield (32.16 t ha-1) was obtained by the application of NPSB fertilizer at highest rate of 300 kg ha-1 which was followed by the application of 250 kg ha-1. Gudane (29.52 t ha-1) and Belete (29.48 t ha-1) produced significantly higher marketable tuber yield than Jalane variety. Therefore, growing of the two varieties at highest rates of blended NPSB fertilizer could be recommended in the study area for producers, because of gives higher marketable yield.

Abstract: Cashew cultivation is of paramount importance in West Africa because of its economic, social, and environmental significance. Cashew nuts production in recent years has been growing steadily in this part of Africa, making it the largest producer of raw cashew nuts in whole world. Unfortunately, this success has been achieved by expanding the area under cultivation rather than improving yields. To reverse this trend, it is important to understand the causes of this yield gap despite the high potential, to take stock of the research conducted in this way, and to propose perspectives. For that, documents were collected through Agora, Scopus, and Google Scholar over the period from 2010 to 2020, resulting in the selection of 103 relevant documents on the subject, using specific keyword combinations. Review slips were produced for each document to categorize then synthesize information from the documents. Numerous studies have been conducted in West Africa about the improvement of the plant material, diseases and pest management, soil fertilization, impact of climatic variations, pollination, and application of technical production itineraries. It appears that the yield gap observed in West Africa is due to the poor performance of the plant material that we use, the weak or poor application of good agricultural practices, particularly weeding, pruning, and thinning practices, phytosanitary treatments, and lack of fertilization. The implementation of these practices coupled with the combination of intercropping and beekeeping and the use of growth hormones could more improve cashew nuts production performance in West Africa.
