Item 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 BLENDED NPSB FERTILIZERANDVERMICOMPOST ON GROWTH, YIELD ANDYIELDCOMPONENTS OF GARLIC (Allium sativum L.) UNDERRAINFEDCONDITION IN ENORE DISTRICT, CENTRALETHIOPIA(wolkite university, 2024-03-01) HLINA TILAHUN TEGODAGarlic is economically important, though the productivity is below its potential duetoinappropriate use of soil fertility management practices particularly fertilizer rateandtype had significant role. Therefore, this study was conducted to investigate the ef ect of Blended NPSB and vermicompost fertilizers on the growth, yield and yield componentsof garlic under rain-fed conditions in Enore district, Central Ethiopia. The experiment consisted of four rates of blended NPSB fertilizer (0, 122, 244, and 366 kg ha -1) andfourrates of vermicompost fertilizer (0, 2.5, 5, and 7.5 t ha -1). The treatments were laidout ina Randomized Complete Block Design in a 4×4 factorial arrangement withthreereplications. Data were collected on the phenological, growth, and yield parametersof garlic and analyzed using SAS software version 9.4. ANOVA results showed that all thetested parameters of garlic were af ected highly significantly (p < 0.01) by the interactionef ect, except days to maturity and the number of leaves per plant which was highlysignificantly (p < 0.01) af ected by the main ef ects of blended NPSB and vermicompost fertilizers. Thus, the longest days to maturity of 126.7 and 127.6 were recorded at therateof 244 kg ha -1 NPSB and 7.5 t ha -1 vermicompost fertilizer, respectively. Statisticallythelongest plant height (62.6) and leaf length (55.6 cm) of garlic were recorded fromthecombined applications of 366 kg ha -1 and 7.5 t ha -1 . The highest leaf number of garlic12.98 was recorded from 7.5 t ha -1 VC rate, which is statistically similar with 11.2and10.7 were recorded from 366 and 244 kg ha -1NPSB fertilizer rate, respectively. Similarly, the highest average fresh biomass yield (65.2 g/plant), mean bulb weight (36.8g), number of clove (30.5), biological dry yield (47.5 g/plant) and harvest index (60.7%)were recorded from the combined application of 244 kg ha -1 NPSB and 7.5 tha-1VCfertilizer. The highest marketable bulb yield 13 t ha -1 , total bulb yield 13.3 t ha -1 , andthelowest unmarketable yield 0.32 t ha -1 were recorded from the combined applicationof 244 kg ha -1 and 7.5 t ha -1 . The highest net benefit (3,392,556 ETB ha -1) was recordedfrom the combined application of 244 kg ha -1 blended NPSB and 7.5 t ha -1VCfertilizerwith high MRR (1982.86). The study revealed that the integrated use of 7.5 t ha -1VCand244 kg ha -1 blended NPSB fertilizers improved soil fertility status for sustainable garlicproduction and productivity in the study area. However, more studies needtobeconducted at various agro-climatic conditions to generate more reliable results forconclusive recommendations
