The field experiments was carried out at Bore Agricultural Research Center (BOARC) on Adola Sub-site, during 2015 and 2016 short rainy season with the objective of determining the most suitable time of introducing common bean and select the best common bean variety into maize and common bean intercrop. The experiment was laid out in randomize complete block design (RCBD) with three replications of factorial combination of three common bean varieties (Haramaya, Ibbado and Hawassa Dume) and four time of intercropping (Simultaneously with maize, 2 WAME, 4 WAME and 6 WAME) along with respective sole crops of common bean varieties and maize BH-661. Highly significant interaction effect of variety and time of intercropping were observed on days to flowering, maturity and plant height, whereby simultaneous intercropping of common bean variety provide longer days to flowering and maturity with taller and vigorous growth than delayed intercropping. A highly significant effect of time of intercropping was observed on number of pod plant-1 and seed pod-1, in which the highest mean number were recorded when common bean was simultaneously planted with maize compared to subsequent interseeding. Highly significant interaction effect of variety and time of intercropping were also observed on common bean varieties on hundred seed weight and grain yields, where drastic reduction of hundred seed weight and grain yields were observed due to delayed intercropping. In regards to maize components, only plant height and grain yield were significantly affected by main effect of time of intercropping, in which the highest mean plant height and grain yield were recorded in delayed time of intercropping common bean. On other hand total LER and GMV of Common bean and maize were significantly affected by main effect of time of intercropping. Simultaneous intercropping of common bean with maize proved LER and GMV of 1.36 and 20246 ETB ha-1, respectively. Therefore, simultaneous intercropping of common bean with maize could be recommend for midland of Guji and similar agro-ecology, based on the observed productivity and economic benefit.
本试验于2015年和2016年短雨季在波尔农业研究中心(BOARC)阿多拉分站进行,目的是确定普通豆引进玉米和普通豆间作的最佳时机和选择最佳普通豆品种。试验采用随机完全区组设计(RCBD),对3个普通豆品种(原屋、伊巴多和哈瓦萨杜姆)进行因子组合3个重复,4次间作(同时与玉米、2个WAME、4个WAME和6个WAME),分别与普通豆品种和玉米bh661单作。品种与间作时间对开花、成熟天数和株高的互作效应极显著,其中普通豆品种同期间作比延期间作的开花和成熟天数更长,生长更高、更健壮。间作时间对豆荚-1和种子-1的数量有极显著的影响,其中与玉米同时种植的豆荚-1的平均数量最高。在普通豆品种中,间作品种和间作时间对百粒重和籽粒产量也有极显著的互作效应,其中由于间作延迟,百粒重和籽粒产量显著降低。在玉米各组分中,间作时间的主效应仅对株高和籽粒产量有显著影响,其中平均株高和籽粒产量最高的是间作延迟时间的普通豆。间作时间的主效应对大豆和玉米的总lerv和GMV有显著影响。普通豆与玉米同时间作的LER和GMV分别为1.36和20246 ETB ha-1。因此,根据观察到的生产力和经济效益,在谷集中部地区和类似的农业生态系统中,可推荐普通豆与玉米同时间作。

Potato is one of the most important food crops grown in mid and high altitude areas of Ethiopia. To meet the increasing demand of potato several potato genotypes have been introduced and evaluated at different areas of the country. However, the performances of different released potato varieties were not yet assessed in the study area. To this end, the present study was undertaken with the focus on determining the adaptability of Irish potato varieties for yield and yield components. It was conducted at Kaffa zone Adiyo District in Alarigeta experimental sub-station in 2013 and 2014 Belge cropping season. Seven improved potato varieties; namely Bule, Marachare, Wochecha, Dancha, Jallanie, Gudanie and Belete were used as treatment. Treatments were arranged in randomized complete block design with three replications. Average tuber diameter, average tuber number, average tuber weight, marketable tuber number, unmarketable tuber number, total tuber number, marketable tuber yield, unmarketable yield and total tuber yield data were recorded and submitted to SAS software version 9.0. Analysis of variance for each year showed significant (p<0.05) difference among the varieties for all studied traits except Average tuber diameter and marketable tuber number in 2013 and Average tuber diameter and unmarketable tuber yield in 2014. The highest and consistent tuber yield was found in variety Belete (40.54 t/ha and 39.98 t/ha) in 2013 and 2014 respectively. Therefore, variety Belete, which was given high yield in both years, could be used instated of currently cultivating varieties to increase production and productivity of the crop for better enhancement of food security and livelihood income of the locality.
马铃薯是埃塞俄比亚中高海拔地区最重要的粮食作物之一。为了满足日益增长的马铃薯需求,在全国不同地区引进和评价了几种马铃薯基因型。然而,在研究区尚未对不同的马铃薯品种进行性能评价。为此目的,本研究的重点是确定爱尔兰马铃薯品种对产量和产量组成部分的适应性。试验于2013年和2014年比利时种植季在Alarigeta试验分站的Kaffa区Adiyo区进行。7个马铃薯改良品种;分别为blue、Marachare、Wochecha、Dancha、Jallanie、Gudanie和Belete。处理采用随机完全区组设计,3个重复。记录平均块茎直径、平均块茎数、平均块茎重量、可售块茎数、滞销块茎数、总块茎数、可售块茎产量、滞销块茎产量和总块茎产量数据,并提交至SAS软件9.0版本。各年份方差分析表明,除2013年平均块茎直径和可售块茎数、2014年平均块茎直径和不可售块茎产量外,各品种间差异均显著(p<0.05)。块茎产量最高和稳定的品种分别是2013年和2014年的Belete (40.54 t/公顷和39.98 t/公顷)。因此,这两年都获得高产的Belete品种可以代替目前种植的品种,提高作物的产量和生产力,更好地提高当地的粮食安全和生计收入。

The objective of this review work was to explore scientific facts on some of the key climatic and agronomic factors that affect production of quality bread wheat seed. Since it was impossible to cover all production factors once, selection of some of the factors was done. The selected factors for this review were rainfall and temperature among climatic factors while, seed rate and nitrogen fertilization were from agronomic factors. From the investigations of various workers, it could be concluded that rainfall, temperature, seed rate and nitrogen fertilization are some of the key factors that highly influence the state of the physiological processes in seeds and finally affect the yield and quality of seeds.

Kava (Piper methysticum) production is decreasing very rapidly on a yearly basis. Kava is the traditional ceremonial drink and one of the major sources of income for the farmers in Fiji Islands. Kava farming is practiced by many Fijians in the highlands of Fiji. Fiji is a tropical country, prompt to cyclones and adverse weather conditions, these adverse weather conditions has continuously contributed towards decreasing kava production in the country and other Pacific Islands. There are 12 cultivars of kava distributed across the Pacific Island and Fiji itself acquires 12% of the total cultivars, besides Vanuatu which acquire 82% of the cultivars. Kava takes minimum of 3 years to attain its full maturity and in that 3 years plants go through various kinds of survival pressure and apart from weather conditions, Kava farmers face crop management issues such as Kava pests and diseases.
卡瓦胡椒(Piper methysticum)的产量每年都在迅速下降。卡瓦是传统的仪式饮料,也是斐济群岛农民的主要收入来源之一。卡瓦种植是斐济高地上许多斐济人的习俗。斐济是一个热带国家,容易受到旋风和恶劣天气条件的影响,这些恶劣天气条件不断导致该国和其他太平洋岛屿的卡瓦产量减少。卡瓦有12个品种分布在太平洋岛屿上,斐济本身获得了总品种的12%,瓦努阿图获得了82%的品种。卡瓦树至少需要3年才能完全成熟,在这3年里,植物经历各种生存压力,除了天气条件外,卡瓦农民还面临作物管理问题,如卡瓦病虫害。

Snap bean is one of the newly introduced legume crops in Ethiopia and it is an important crop in the provision of food security and earing forging currency. It responds much better to the application inorganic fertilizer especially N and P fertilizers due to lack of nodule forming bacteria in the soil and low in building of fertile soil. However, information concerning the production package of snap bean at Jimma was scares and due to this there is limited evidence in the response of snap bean to inorganic fertilizers (N and P fertilizers) which can increase yield and quality. Cognizant to this fact, the experiment was conducted to realize the effect N and P fertilizers rates on yield and yield components of snap bean at Jimma, Southwestern Ethiopia. The experiment consisted of two factors, five levels of N (0, 41, 82, 123, and 164 kg/ha) and four levels of P (0, 46, 92 and 138 kg/ha) arranged 5 × 4 in randomized complete block design with three replications. N as urea was applied in split application (50% at sowing and 50% at flowering) whereas the full dose of P was applied at sowing as triple super phosphate. There was a significant difference (P ≤ 0.05) for main effects of N and P fertilizer rates for all yield and yield component variables. Out of the whole variables tap root length were significant by the interaction effects of N and P fertilizers rate. The result showed that the maximum marketable pod yield was obtained from 123 kg/ha N and 92 kg/ha P2O5 fertilizer application rates. While, the minimum marketable pod yield was recorded from the application of 0 N and P fertilizer rate. So, form this experiment application of 123 kg/ha N and 92 kg/ha P2O5 increased the marketable pod yield of snap bean at Jimma. Since, the experiment was conducted in a single location and season. So, repeating the experiment for more seasons and similar location would help us draw sound conclusive recommendations to the end users.
豆角豆是埃塞俄比亚新引进的豆科作物之一,是保障粮食安全和铸造货币的重要作物。由于土壤中结瘤细菌较少,土壤肥力较低,对施用无机肥尤其是氮、磷的反应较好。然而,关于吉马豆角生产包装的信息很少,因此,关于豆角对无机肥料(氮和磷肥料)的反应的证据有限,无机肥料可以提高产量和质量。认识到这一事实,在埃塞俄比亚西南部的Jimma进行了氮肥和磷肥施用量对豆荚产量和产量组成的影响试验。试验采用2个因素,5个水平N(0、41、82、123和164 kg/ha)和4个水平P(0、46、92和138 kg/ha), 5 × 4随机完全区组设计,3个重复。氮肥作为尿素分次施用(播期50%,开花期50%),全量磷作为三倍超磷酸盐在播期施用。氮磷肥施用量对各产量及产量构成变量的主效应差异显著(P≤0.05)。在所有变量中,根长受施氮量和磷肥量的交互作用显著。结果表明,施用123 kg/ hm2氮肥和92 kg/ hm2 P2O5时,豆荚产量最高。氮磷肥用量为0时,可售豆荚产量最低。因此,在本试验中,施用123 kg/ hm2氮肥和92 kg/ hm2 P2O5可提高吉马菜豆的可销荚果产量。因为,实验是在一个地点和季节进行的。因此,在更多的季节和类似的地点重复实验将有助于我们向最终用户提出合理的结结性建议。

Standardization of a reproducible protocol for in vitro rough lemon rootstock mass propagation was conducted at Tigray Biotechnology Center Plc., Plant Tissue Culture Laboratory, Mekelle, Ethiopia in 2015/2016 cropping season. Rough lemon is the frequently used rootstock both in the world and Ethiopia citrus fruit production, particularly in the Tigray region due to its superior performance over other rootstocks. However, seedlings produced through conventional ways are not recommended to be used in orchards due to variability problems caused by its polyembrony nature. To overcome such variations, in vitro regeneration of rough lemon rootstocks was performed using nodal segments and shoot tips as explant types. The explants were inoculated on MS medium supplemented with 5% scurose and 250 mg/L streptomycin followed to surface sterilization. The most effective and reproducible auxin (NAA), cytokinin (BA) and gebrillenllic acid (GA3) for in vitro shoot and root induction in rough lemon rootstocks were determined. Almost all IBA and BA treatments resulted in almost 100% shoot induction except for at 0.0 and 0.1 mg/L IBA and at 1.5 and 2.0 BA mg/L. Nodal segments induced a higher percentage of explant response with longer shoots in a shorter period of time than shoot tips, which produced more shoots and leaves than nodal segments. The effect different BA and IBA concentrations on various parameters of proliferation were studied. Full strength medium produced more regenerated shoots and leaves per shoot than half-strength MS medium. In addition, longer shoots formed with 0.1 mg/L GA3 than culture medium without this plant growth regulator. Root length decreased with higher concentration of NAA and the longest root (2.5 ± 0.22 cm) was found in the 1.0 mg/L NAA and followed by (1.95 ± 0.22 cm) at 0.5 mg/L of NAA. The rooted plants were successfully established in the greenhouse on the substrate called coco-peat and sand, and their survival rate was found to be 98%.

在Tigray生物技术中心进行了柠檬粗砧木离体大量繁殖的可重复性方案的标准化。2015/2016种植季,埃塞俄比亚Mekelle植物组织培养实验室。粗柠檬是世界和埃塞俄比亚柑橘类水果生产中经常使用的砧木,特别是在提格雷地区,由于其优于其他砧木的性能。然而,由于其多胚性造成的变异性问题,不建议在果园中使用传统方法生产的幼苗。为了克服这种变异,采用节段和茎尖作为外植体进行了柠檬粗砧木的离体再生。将外植体接种于添加5%蔗糖和250 mg/L链霉素的MS培养基上,进行表面灭菌。测定了生长素(NAA)、细胞分裂素(BA)和黄黄烯酸(GA3)对粗柠檬砧木离体诱导芽和根的最有效和最具重复性。除了0.0和0.1 mg/L IBA和1.5和2.0 BA mg/L IBA处理外,几乎所有IBA和BA处理的诱导率都接近100%。茎节段在较短的时间内诱导的外植体响应率高于茎尖,茎尖比茎节段产生更多的芽和叶。研究了不同BA和IBA浓度对细胞增殖各项参数的影响。全强度培养基比半强度MS培养基每枝再生芽和叶片更多。此外,添加0.1 mg/L GA3的培养基比不添加该植物生长调节剂的培养基形成的芽长。随着NAA浓度的升高,根长逐渐减小,在1.0 mg/L NAA处理下,根长为2.5±0.22 cm,在0.5 mg/L NAA处理下,根长为1.95±0.22 cm。生根植株在温室中成功地建立在名为可可豆和沙子的基质上,其成活率为98%。这些结果表明,这些因素的标准化可以帮助开发一个商业上可行的粗柠檬组织培养系统。此外,这也表明了基于植物品种的柑桔种离体方案开发和优化的必要性。

Rough lemon is the frequently used rootstock both in the world and Ethiopia citrus fruit production, particularly in the Tigray region due to its superior performance over other rootstocks. However, seedlings produced through conventional ways are not recommended to be used in orchards due to variability problems caused by its polyembrony nature. To overcome such variations, in vitro regeneration of rough lemon rootstocks was performed using nodal segments and shoot tips as explant types. The explants were inoculated on MS medium supplemented with 5% scurose and 250 mg/L streptomycin followed to surface sterilization. The most effective and reproducible auxin (NAA), cytokinin (BA) and gebrillenllic acid (GA3) for in vitro shoot and root induction in rough lemon rootstocks were determined. Almost all IBA and BA treatments resulted in almost 100% shoot induction except for at 0.0 and 0.1 mg/L IBA and at 1.5 and 2.0 BA mg/L. Nodal segments induced a higher percentage of explant response with longer shoots in a shorter period of time than shoot tips, which produced more shoots and leaves than nodal segments. The effect different BA and IBA concentrations on various parameters of proliferation were studied. Full strength medium produced more regenerated shoots and leaves per shoot than half-strength MS medium. In addition, longer shoots formed with 0.1 mg/L GA3 than culture medium without this plant growth regulator. Root length decreased with higher concentration of NAA and the longest root (2.5 ± 0.22 cm) was found in the 1.0 mg/L NAA and followed by (1.95 ± 0.22 cm) at 0.5 mg/L of NAA. The rooted plants were successfully established in the greenhouse on the substrate called coco-peat and sand, and their survival rate was found to be 98%.
