Item GROWTH AND YIELD RESPONSE OF FOOD BARLEY (Hordeum vulgars L.) VARIETIES TO SEEDING RATES IN CHEHA DISTRICT, GURAGE ZONE, CENTRAL ETHIOPIA(wolkite university, 2025-05-02) TIZAZU ANKTAWE GORAGABarley (Hordeum vulgare L.) is an important food security and cash crop in Central Ethiopia. The productivity of the crop is very low in many parts of the Gurage zone, including the Cheha district. Several factors are responsible for the area's low crop yield. There is limited information on the response of various barley genotypes and seed rates for optimal production. Hence, a field experiment was conducted to evaluate the effects of seeding rate and genotypes on growth, yield, and yield components of barley in Cheha District. Factorial combinations of four food barley varieties, namely HB-1307, HB1966, HB1965, and Local genotype, and four seeding rates (75, 100, 125, and 150 kg ha- 1 ) were used. The experiment was laid out in a randomized complete block design with three replications. The result showed that seeding rate and varieties significantly affected the majority of food barley growth and yield parameters. The highest days to 50% heading (82 days), and days to physiological maturity (139 days), were recorded on 75 kg of seeding rate ha-1 with variety HB1966, while, the highest plant height (96 cm) was recorded with the use of 150 kg ha-1 of food barley seeding rate on HB1966 variety. The highest spike length (8 cm), total number of tillers (8), number of productive tillers (7), and number of kernels spike- (66) were recorded on the use of a 75 kg ha-1 seeding rate with the HB-1307 variety. The highest biomass yield (13.18 t ha-1 ) and straw yield (8.95 t ha-1 ) were recorded on 150 kg of seeding rate ha-1 with variety HB-1307. The highest grain yield (4.89 t ha -1 ), thousand seed weight (57g), and harvest index (43%) were recorded on variety HB-1307 with a 125 kg ha-1 seed rate. Net benefit of 129375.5 ETB ha-1 was obtained from the treatment combination of 125 kg ha-1 food barley seed rate with Variety HB-1307. The result indicated that the food barley variety HB-1307 with a seeding rate of 125 kg ha-1 is economically feasible and profitable for the study area. Since the present study was conducted only in a single season and location, it is necessary to conduct similar experiments further in different seasons and locations to come up with concrete and workable recommendation for varieties and seeding rates of food barleyItem EFFECT OF DIFFERENT TYPES OF FERTILIZERS ON YIELD AND YIELD COMPONENTS OF ONION (Allium cepa L.) VARIETIES IN ENEMORE WOREDA OF GURAGE ZONE, ETHIOPIA(wolkite university, 2022-06-03) MESFIN WONDIMU HABTEOnion is one of the most important vegetable crops produced as a condiment for home consumption and income sources in many parts of Ethiopia. However, the productivity of onion is low due to various limiting factors, among which low soil fertility and lack of improved site specific varieties are the major ones. Hence, this study was initiated to evaluate and determine the effects of different types of fertilizers on the yield and yield components of nationally released onion (Allium cepa L.)Varieties in Enemore Woreda (district) of Gurage zone. A combination of four fertilizer treatments and four varieties were used. These were: 200kg ha-1NP, 242kg ha-1NPS, 244kg ha-1NPSB and 257kg ha1NPSZn; and Bombay Red, Nafis, Red Creole and Nasik Red of onion verities. The experiment was laid out in Randomized Complete Block Design, under factorial arrangement and with three replications. There were a total of 16 treatment combinations and 48 experimental units. Data were collected on various parameters of growth, yield and yield components using standard procedures. The data were analyzed using a SAS software version 9.3. The analysis of variance revealed that the main effect of both the different types of fertilizers and onion varieties influenced plant height, date of maturity and bulb dry weight. However, the unmarketable bulb yield was highly significantly (p<0.001) affected only by varieties. There was also statistically highly significant (p<0.001) interaction effect on leaf length, leaf number, bulb diameter, average fresh weight, marketable bulb yield, and total bulb yield. Accordingly, the treatment combination of 244 kg ha-1 NPSB fertilizer and variety Red Creole recorded the highest plant height (68.25cm), bulb diameter (6.1cm), leaf length(59.9cm),leaf number (13.66), average bulb fresh weight (103.66g), marketable yield (31.64 t ha-1 ) and total bulb yield(32.25 t ha-1 ). On the other hand, correlation analysis showed that almost all the tested yield and yield component parameters were highly significantly and positively correlated with the marketable bulb yield of onion. Besides, as revealed by the partial budget analysis, plants supplied with 244 kg ha-1 NPSB and variety Red Creole recorded the highest net benefit if Birr 462412.00 with acceptable Marginal Rate of Return (MRR,3441.7%), which can be recommended for economical production of onion at Enomore Woreda. Nevertheless, since, the study was conducted only for a single season and one location, further research is recommended to be carried out at different seasons of the year and multiple potentially representative locations.Item POST-HARVEST LOSS FACTOR ASSESSMENT AND TUBER STORABILITY EVALUATION OF POTATO (Solanum tuberosum L.) VARIETIES UNDER DIFFERENT STORAGE STRUCTURES IN GUMMER DISTRICT, CENTRAL ETHIOPIA(wolkite university, 2024-06-03) SISAY SIFIR ZEMEDIn the study area,there is huge potato production with high post harvest loss . Therefore, the current study was initiated to assess the main factors responsible for postharvest losses of potatoes and to evaluate tuber storability using different storage structures. For the survey, a total of 120 farmers and 6 key informants were interviewed from four (4) kebeles which were selected purposively. A descriptive research design was employed and quantitative data were measured and analyzed by using SPSS software version 20. The results indicated that inadequate awareness, lack of appropriate harvesting materials inappropriate harvest maturity determination and storage facilities as well and market uncertainty were as the main factors that contribute to the prevailing high level of postharvest losses of potatoes in the area. The result indicated that 62% of the respondents have no awareness, 23% have medium awareness and 15% have low awareness of postharvest losses and postharvest handling methods for potato tubers. For harvesting, majority of the respondents (63.3%) use rake to dugout tubers. For the experiment, four storage structures (pit, bamboo baskets, floor, and loft) and two potato varieties (Gudene and ‘Key dinch’) were laid out in 4×2 Complete block Block design, and data were collected frequently in a time interval. The analysis of variance showed that the main effect of variety, storage structure, and time was significantly influenced all the postharvest parameters except variety and pH content of the tuber. The lowest weight loss (6.11 and 6.22) was recorded from pit storage and at 30 days of storage, respectively. The longest days to 50% sprouting were obtained from all treatment interactions except from the variety Gudene interacted with the floor (72 days) and with basket storage (72 days). None of the tubers were sprouted by the interaction of Gudene with the loft method and were stored for 30, 60, and 90 days after storage. The highest dry matter content (24.5%) was obtained from tubers stored in the pit after 90 days of storage whereas the lowest dry matter content (21.5%) was obtained from tubers stored on the floor for 90 days after storage. for better storage stability of potato tubers, loft storage method with Gudene variety were found to be more ideal for extending the storage or shelf-life of the tubersItem RESPONSE OF GARLIC (Allium sativum L.) VARIETIES TO TYPES OF BLENDED FERTILIZERS IN MIHUR-AKLIL DISTRICT OF GURAGE ZONE, ETHIOPIA(wolkite university, 2023-07-02) HABTEMARIAM FIKADU BEREKAGarlic (Allium sativum L.) is one of the major vegetable and cash crops cultivated throughout the world including Ethiopia. Garlic productivity in Ethiopia (9.18t ha-1 ) is very low compared to the world average (18.4t ha-1 . Its production is constrained by several factors including lack of productive varieties, improved agronomic practices, diseases and insect pests. Among these, inappropriate type of fertilizer and lack of improved varieties are the major ones. Hence, this experiment was conducted in 2023 at Mihur-Aklil District of Gurage zone, Ethiopia with the objective of investigating the effect of blended fertilizer type on growth, yield and yield attributes of garlic varieties. The experiment was laid out in a randomized complete block design in three replications using 20 treatments formed from factorially combined five garlic varieties (Tsedey, Kuriftu, Chefe, Holeta and local) and four types of blended fertilizers (0, NPS, NPSB and NPSZn ). Data on different Phenological, growth, yield and yield related variables were collected and analyzed using SAS, version 9.3. The analysis of variance showed that most of the studied parameters were significantly affected by the interaction of the two factors. The highest total bulb yield (17.08t ha-1 ), marketable bulb yield (14.94 ha-1 ), bulb weight (37.27g), bulb diameter (24.27mm), plant height (77.8cm), leaf length (52.33) and leaf area (38.80cm2 ) was recorded from Tsedey variety at NPSB blended fertilizer type while the widest leaf width (1.04cm) was recorded from Tsedey variety treated with NPSZn blended fertilizer type and the highest clove weight (2.70g) was recorded from Kuriftu variety treated with NPSZn blended fertilizer type. The partial budget analysis result showed that the highest net benefit of 963881.281Eth-Birr ha-1 was obtained from variety Tsedey and NPSB fertilizer. Thus, from the present study, the variety Tsedey and NPSB fertilizer are recommended for economic production in the study area and areas with similar agro-ecological settings. However, since the study was carried out only for one cropping season and in single location, it is as well recommended that to be repeated across seasons and locations.Item STUDY ON THE COMBINED EFFECT OF NPSB FERTILIZER RATES AND VARIETIES ON GROWTH, YIELD AND YIELD COMPONENTS OF GARLIC (Allium sativum L.) IN GUMMER DISTRICT OF GURAGE ZONE, ETHIOPIA(wolkite university, 2022-02-01) JADU KIBRET AGERCHUGarlic (Allium sativum L.) is one of the major horticultural crops known worldwide with respect to its production and economic value. It is also the main bulb crop produced in Ethiopia, including the southern region. However, farmers are producing garlic from locally available varieties without or with low rates of fertilizer input which results in low yield. Therefore, this experiment was conducted to evaluate the response of garlic varieties to different rates of NPSB. Three improved garlic varieties (Kuriftu, HL and Tseday) and one local cultivar (‘Tuma”) and four levels of NPSB fertilizer rates (0, 144, 244, 344 kg NPSB ha ˡ ) were used. The experiment was arranged in a 4 X 4 factorial experiment under a Randomized Complete Block Design (RCBD) with three replications. Plant height (cm) and leaf number were significantly influenced by the interaction effect of varieties and NPSB fertilizer except leaf length (cm) that was significantly influenced only by the main effect of variety and NPSB. All yield and yield related traits were significantly influenced by the interaction effect of varieties and NPSB fertilizer rates except days to 50% emergence and bulb weight (g) that were significantly influenced only by the main effect of variety and NPSB. The highest total bulb yield was obtained from variety Kuriftu (8.81 t ha ˡ ) at the NPSB rate of 244 kg ha ˡ , and the lowest recorded from the local cultivar (5.52 t ha ˡ ) without NPSB (0 kg) fertilizer application. The maximum plant height (74.17cm) was recorded from variety HL at 244 kg/ha NPSB and the highest number of garlic leaves (10.33) were obtained from variety Kuriftu that received the highest NPSB rate of 344 kg/ha. The longest leaf was recorded from variety Tsedey (34.875cm) which was followed by variety Kuriftu (34.154cm) and HL (32.596cm). The highest statistically significant bulb weight was recorded equally from variety Kuriftu, Tsedey and HL 43.42g, 42.77g and 41.92g respectively. Marketable bulb yield was very highly significant (P<0.001) and positively correlated with leaf number (r =0.68***), bulb weight (r =0.64***), bulb diameter (r =0.72***), and highly significant (P<0.01) and positively correlated with plant height (r =0.41**) and leaf length (r =0.46**). The cost benefit analysis indicated that variety Kuriftu with the application rate of 244 kg NPSB ha ˡ gave the maximum MRR (1974.3%).Item EFFECT OF INTER ROW SPACING AND VARIETIES ON GROWTH AND YIELD OF FENUGREEK (Trigonella foenum-graecum L.) AT WOLISO DISTRICT, SOUTH WEST SHOA ZONE, ETHIOPIA(wolkite university, 2024-05-02) LETA ABEBE BEDADAFenugreek (Trigonella-foenum-graecum L.) is a legume crop which is used as a spice, vegetable, animal feed and medicinal plant. Inter row spacing is one of the yield limiting factors on fenugreek production. A field experiment was conducted at Woliso Polytechnic College during the 2023/2024 cropping season. To evaluate and determine the combined effect of inter-row spacing (10cm, 20cm, 30cm and 40cm) and varieties (Burqa, Chala, Ebbisa, Wereilu and one local variety for check) on yield and yield components fenugreek. The experiment was laid out under Randomized Complete Block Design with Factorial arrangement and three replications. Based on the data analysis, the higher yield and yield components were recorded from planting of fenugreek with the wider inter-row spacing of 40cm. The shortest days for 50% flowering (44.6 days), the shortest days for 90% maturity(117.9), the highest number of primary branches (6.73), the highest number of pods per plant-1 (29.33), the highest number of seeds per pod-1 (21.6), the highest pod length (19.3), the highest 1000g seed weight (20.6), the highest above ground biomass (3568.33Kg ha-1 ), the highest harvesting index (40.2% and the highest seed yield (1586) were recorded from the 40cm inter-row spacing followed by 30cm. On the other hand, the lowest yield (324.66 kg ha-1 ) and yield attributes were recorded when the crop was grown under the smallest inter-row spacing of 10cm. The higher number of primary branches, number of seeds pod-1 (21), pod length (19.3), 1000g seed weight (20g) and seed yield (1586 kg ha-1 ) were recorded from Burka inter acted with 40cm followed by Chala, Wereilu, and Ebbisa verities whereas the lower grain yield and yield component was recorded from with the interaction of 10cm. From the current research-based yield and yield component planting of Burka variety with 40 cm inter row spacing is performing well and recommended to the local farmer to increase the yield of fenugreek crop.
