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.

Ethiopian agriculture is dominated by small holder farmers with an average per capita land holding of less than a hectare. The production system mainly depends on rain fed system and low input including fertilizer and pesticides used. In order to characterize the climate of Mieso, Melkassa, and Adami Tulu located in CRV of Ethiopia daily climate data were obtained from MARC for Mieso, Melkassa and Ademi Tulu and used for characterization using INSTAT V3.37. The mean start, end of season and length of growing season (LGS) are found to be May 26, September 14, and 99 days at Mieso site; May 27, October 1st and 97 days at Melkassa site; May 26, September 11, and 109 days in Adami Tulu site. The rainy days ranged from 92-165, 92-147, and 92-110 days in Mieso, Melkassa and Adami Tulu, respectively. Hence, developing new varieties and use of appropriate soil moisture conserving tillage practices will enhance adaptation capacity of farmers under changing climate in CRV of Ethiopia. The changes in rainfall conditions have a direct and immediate impact on the performance of agricultural sector as well as on the country’s total GDP. In order to characterize the climate of Mieso, Melkassa, and Adami Tulu located in CRV of Ethiopia daily climate data were obtained from MARC for Mieso, Melkassa and Ademi Tulu and used for characterization using INSTAT V3.37. The seasonal mean rainfall at Mieso, Melkassa and Adami Tulu is 438, 577.7 and 430.3 mm. The probability of occurrence of dry spell lengths of 5, 7, 10, and 15 days reaches minimum value during the peak rainy months and then starts to increase after the end of the rains. Generally, for the study periods the probability of longer dry spells increases rapidly from first dekadal of September onwards. To take risks of longer dry spells and decide to plant during earliest months of the season, farmers should get access to irrigation and also other mechanisms that minimize the loss of moisture from the farm land.

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.

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.

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%. These results suggest that standardization of these factors can help in development of a commercially viable tissue culture system for rough lemon. Moreover, it signifies the need of plant variety based in vitro protocol development and optimization across citrus species.
