All the collected data were analyzed by using the SPSS software and difference among means were also compared. A total of 280 farmers fi eld were surveyed. 98% of the surveyed farmers used traditional storage structures. Sitophilus zeamais was occurred with a dominant mean number 120, 115 & 116 in Asosa, west Gojam & Hawasa areas, respectively. High mean 31.84% of grains damaged was recorded in the sample collected from Hawasa whereas, low mean 6.03% in the sample collected from Buno Bedele areas. High mean 18.00% of weight losses was recorded in the samples collected from Hawasa. The majority 64% of the surveyed farmers stored their grains for more than eight months. The mean number of weevils, weight loss and grain damage showed an increasing trend as the storage periods increased because of most of the farmers stored their maize with husk and/or unshelled in the house; store with cobs in bare ground which favors moisture development and temperature increment in the store. From this survey, it can be concluded that most of the surveyed farmers used traditional storage structures, stored their grains either shelled or unshelled, heap with stalk in the fi eld for a longer period and used insecticides for the control maize weevils. These insecticides have harmful effect on the environment and human health. Therefore, uses of hermetic storage technology can be suggested to the farmers for, reducing weight loss, grains damage, use of insecticides and providing appropriate grains quality.

The experiment was conducted using eleven potato genotypes with one standard check variety (Belete) and a local check at Kulumsa Agricultural Research Center, Bekoji sub-station during 2020-2021. Data were collected for tuber yield, tuber dry matter content (%), plant height (cm), stem number, specific gravity, and phenological parameters. Since the two seasons had heterogeneous error variance, analysis was carried out separately. In 2020, correlation analysis indicated that the tuber yield was positively and significantly associated with stem height (0.608), marketable tuber (0.997) and positively associated with tuber dry matter content, stem number per plant, days to maturity, while it was negatively correlated with specific gravity, days to emergence and days to flowering at the...

However, amaranths is not popularized and commercialized in our country. The objective of this experiment was to evaluate the yield, yield components and mineral compositions. The experiment was conducted at Assosa agricultural research center in 2018/2019 cropping seasons. The experiment was laid out in RCBD in three replications. Six genotypes of amaranths were evaluated. The analysis of variance showed that no significance difference (P>0.05) among genotypes in terms of yield components and yield. However, there were numerically difference among genotypes in terms of plant height, leaf yield and grain yield. The mineral compositions of genotypes were analyzed. The highest content of essential minerals required for human body was recorded by the genotype of 013/2015. So, tentatively we recommend that the genotype of 013/2015 had good essential minerals for the human body. In future further study should be done over locations and over years.

Data were collected for tuber yield, tuber dry matter content (%), plant height (cm), stem number, specific gravity, and phenological parameters. Since the two seasons had heterogeneous error variance, analysis was carried out separately. In 2020, correlation analysis indicated that the tuber yield was positively and significantly associated with stem height (0.608), marketable tuber (0.997) and positively associated with tuber dry matter content, stem number per plant, days to maturity, while it was negatively correlated with specific gravity, days to emergence and days to flowering at the genotypic level. Total tuber yield was positively and significantly correlated with days to maturity (0.640), stem height (0.791), marketable tuber (0.977) and stem number at the genotypic level. While specific gravity was positively and significantly correlated at the phenotypic level; and negatively at the genotypic level in the second season. Results of path analyses indicated that marketable tubers had the highest positive direct effect (+1.059) on total tuber yield followed by days to flowering (+0.057) and specific gravity (+0.026) in 2020 while marketable tuber (0.7107), stem height (0.2842), tuber dry matter content (0.0078), days to maturity (0.1250) had also positive direct effect in 2021. In addition, most of the indirect effects of yield components on tuber yield were significant and positive. Significant effects of marketable tuber, tuber dry matter content, days to maturity and stem height on total tuber yield, indicated that they could be used as the criteria for potato improvement and breeding programs.

The experiment was set with eight treatments (recommended NP, three different blended rates for each NPSB and NPSBZn and unfertilized plot) laid out in randomized complete block design with three replications using a hot pepper variety Mereko Fana. In the blends since N content was low, supplementary N was applied from Urea to optimize N needs of the crop. The results of the study revealed that the crop phonological parameters (days to flowering and maturity, fruit dry yield and average dry fruit weight) were significantly (p<0.05) affected by blended fertilizer type and rates. The days to flowering and maturity were significantly (p<0.05) improved by application of 100 kg NPSBZn + 29 N kg ha-1. The maximum total dry fruit yields (2.44 t ha-1), the highest fruit uptake of nitrogen (50.1), phosphorus (9.9) and sulfur (4.1 kg ha-1), and the highest apparent nutrient recovery for N (47.91%) were recorded with the application of 150 kg + 44 N kg ha-1 NPSBZn; while higher agronomic efficiency of N (9.59 kg pod kg-1) and P (12.80%) were recorded with the application of 100 kg + 29 N kg ha-1 blended fertilizer rate. In general, the nutrient use efficiency of the blended fertilizers tested was acceptable and high. The uptake of N, P, K and S were significantly and highly correlated (p< 0.01) with total dry fruit yield. Therefore, the study recommends 150 kg NPSBZn + 44 N kg ha-1 blended fertilizer for sustainable hot pepper production in Assosa area of Western Ethiopia.

Jars were opened on day 2, 5, 10, 20 and 40 post ensiling for analysis of nutritive value and silage fermentation characteristics. In addition, samples of day 40 were subjected to a 5 day aerobic test where CO 2 production was measured. After 40 days of ensiling, inoculation reduced (P&lt;0.05) silage pH, butyric acid and ammonia-N while increasing acetic and lactic acids content compared to control. The aerobic stability of silage was improved (P&lt;0.05) with whey and LB as indicated by lower CO 2 production compared to control. It was concluded that silage produced from citrus leaves was poorly fermented as indicated by high pH and low lactic acid contents.

Besides this, different environmentalists complain about the industry because the industry uses too many pesticides and chemical fertilizers which damage the environment. The objective of this paper is to review the ecological implication of floriculture industries on surrounding environment. Environmental implication of floriculture involved the intensive use of water as well as soil, the water, and air pollution because of its intensive and toxic chemical usage and waste disposal system of the industries. The flower industry uses, 90% of groundwater resources. As planting media 40% uses soil bed, hydroponics 30% and the rest 30% also used both planting media. The waste is discharged directly to the water body by 30% of the farm, and 40% are a drain to the land. The land use change is also visible, 30% of the farm is established on local farme...

However, scarcity of high yielding varieties as well as lack of superior planting material seriously constrains productivity of the crop. Research project was initiated aiming at studying adaption of true seed shallot for yield and components. A series of experiments were conducted using the randomized complete block design to identify the appropriate variety for production of bulb yield. The combined analysis of variance results for marketable bulb yield (kg/plot), unmarketable bulb yield (kg/ha), total bulb yield (kg/plot) and total bulb yield (t/ha). The results showed that the mean squares for main factors of genotype and year as well as interaction of genotypes x year were significant for marketable bulb yield (kg/plot). The overall marketable yield range of the shallot varieties was from 256.56- 171.49qtha-1 and the a...

To identifying adaptable coffee varieties that could exhibit higher yield to maximize coffee production and productivity to the environments of mao-komo special distinct, western Ethiopia, in order to diversify their production and to maximize the income of the farmers in the area. Based on this fact, a field experiment was conducted using six released coffee varieties, arranged with a randomized complete block design with three replicates to select varieties which could exhibit relatively better performance at the area. Those varieties were planted at a spacing of 2 m by 2 m between plants and rows, respectively and were evaluated for yield and yield components. They were grown with shade of Susbaniasusben. From the evaluated varieties it was noted that parameters as plant height, height up to primary branch, internodes length on main stem, canopy diameter, clean coffee yield had significant difference (p<0.05) among the varieties and the highest clean Coffee yield (1392.9, 1338.5 and 1100 Kg ha-1) was scored by the 75227, 7440 and F59 varieties respectively. On the contrary 74110 exhibited least mean yields of 860.1 Kg of clean coffee per hectare. Based on the yield performance 75227 and 7440 varieties were recommended to producers of coffee at Mao-komo area and demonstration needs to be investigated.

This may also lead to them delaying or dropping out of school when the combination of being a caregiver and their education program are too demanding. This survey study aims to explore the consequences for students of bachelor or vocational education programs when they are growing up with a chronically ill family member and the influence of various background characteristics and risk factors. Methods: A survey was sent to 5997 students (aged 16-25 years) enrolled in bachelor or vocational education programs in the north of the Netherlands. The content of the survey was based on a literature study and consultation with experts. Descriptive statistics, Chi-square tests, and logistic regression analyses were performed. Results: A total of 1237 students (21%) responded to the survey. A sub group of 237 (19%) students (mean age 21(2.2); 87% female) identified themselves as growing up with a chronically ill family member. More than half (54.9%) of these students indicated that they experienced negative consequences in daily life. A significant association (OR .42, p < .02) was found for these consequences and the level of education for which attending vocational education yields a higher risk. In addition, growing up with a mentally ill family member was associated with a 2.74 (p = .04) greater risk of experiencing negative consequences in daily life compared to students living with a family member with a physical disorder or multiple disorders. Conclusion: Since a substantial number of students growing up with a chronically ill family member indicate serious physical, mental, and social consequences as a result of this care situation, awareness for this specific agegroup is needed. Students with a mentally ill family member and students undertaking vocational education appear to be especially at risk. Further research is required in order to gain insight that is more in-depth into the exact type of problems that these students encounter and the specific needs that they have regarding support.

All the collected data were analyzed by using the SPSS software and difference among means were also compared. A total of 280 farmers fi eld were surveyed. 98% of the surveyed farmers used traditional storage structures. Sitophilus zeamais was occurred with a dominant mean number 120, 115 & 116 in Asosa, west Gojam & Hawasa areas, respectively. High mean 31.84% of grains damaged was recorded in the sample collected from Hawasa whereas, low mean 6.03% in the sample collected from Buno Bedele areas. High mean 18.00% of weight losses was recorded in the samples collected from Hawasa. The majority 64% of the surveyed farmers stored their grains for more than eight months. The mean number of weevils, weight loss and grain damage showed an increasing trend as the storage periods increased because of most of the farmers stored their maize with husk and/or unshelled in the house; store with cobs in bare ground which favors moisture development and temperature increment in the store. From this survey, it can be concluded that most of the surveyed farmers used traditional storage structures, stored their grains either shelled or unshelled, heap with stalk in the fi eld for a longer period and used insecticides for the control maize weevils. These insecticides have harmful effect on the environment and human health. Therefore, uses of hermetic storage technology can be suggested to the farmers for, reducing weight loss, grains damage, use of insecticides and providing appropriate grains quality.

However, amaranths is not popularized and commercialized in our country. The objective of this experiment was to evaluate the yield, yield components and mineral compositions. The experiment was conducted at Assosa agricultural research center in 2018/2019 cropping seasons. The experiment was laid out in RCBD in three replications. Six genotypes of amaranths were evaluated. The analysis of variance showed that no significance difference (P>0.05) among genotypes in terms of yield components and yield. However, there were numerically difference among genotypes in terms of plant height, leaf yield and grain yield. The mineral compositions of genotypes were analyzed. The highest content of essential minerals required for human body was recorded by the genotype of 013/2015. So, tentatively we recommend that the genotype of 013/2015 had good essential minerals for the human body. In future further study should be done over locations and over years.

Total tuber yield was positively and significantly correlated with days to maturity (0.640), stem height (0.791), marketable tuber (0.977) and stem number at the genotypic level. While specific gravity was positively and significantly correlated at the phenotypic level; and negatively at the genotypic level in the second season. Results of path analyses indicated that marketable tubers had the highest positive direct effect (+1.059) on total tuber yield followed by days to flowering (+0.057) and specific gravity (+0.026) in 2020 while marketable tuber (0.7107), stem height (0.2842), tuber dry matter content (0.0078), days to maturity (0.1250) had also positive direct effect in 2021. In addition, most of the indirect effects of yield components on tuber yield were significant and positive. Significant effects of marketable tuber, tuber dry matter content, days to maturity and stem height on total tuber yield, indicated that they could be used as the criteria for potato improvement and breeding programs.

The experiment was set with eight treatments (recommended NP, three different blended rates for each NPSB and NPSBZn and unfertilized plot) laid out in randomized complete block design with three replications using a hot pepper variety Mereko Fana. In the blends since N content was low, supplementary N was applied from Urea to optimize N needs of the crop. The results of the study revealed that the crop phonological parameters (days to flowering and maturity, fruit dry yield and average dry fruit weight) were significantly (p<0.05) affected by blended fertilizer type and rates. The days to flowering and maturity were significantly (p<0.05) improved by application of 100 kg NPSBZn + 29 N kg ha-1. The maximum total dry fruit yields (2.44 t ha-1), the highest fruit uptake of nitrogen (50.1), phosphorus (9.9) and sulfur (4.1 kg ha-1), and the highest apparent nutrient recovery for N (47.91%) were recorded with the application of 150 kg + 44 N kg ha-1 NPSBZn; while higher agronomic efficiency of N (9.59 kg pod kg-1) and P (12.80%) were recorded with the application of 100 kg + 29 N kg ha-1 blended fertilizer rate. In general, the nutrient use efficiency of the blended fertilizers tested was acceptable and high. The uptake of N, P, K and S were significantly and highly correlated (p< 0.01) with total dry fruit yield. Therefore, the study recommends 150 kg NPSBZn + 44 N kg ha-1 blended fertilizer for sustainable hot pepper production in Assosa area of Western Ethiopia.

Jars were opened on day 2, 5, 10, 20 and 40 post ensiling for analysis of nutritive value and silage fermentation characteristics. In addition, samples of day 40 were subjected to a 5 day aerobic test where CO 2 production was measured. After 40 days of ensiling, inoculation reduced (P&lt;0.05) silage pH, butyric acid and ammonia-N while increasing acetic and lactic acids content compared to control. The aerobic stability of silage was improved (P&lt;0.05) with whey and LB as indicated by lower CO 2 production compared to control. It was concluded that silage produced from citrus leaves was poorly fermented as indicated by high pH and low lactic acid contents.

Besides this, different environmentalists complain about the industry because the industry uses too many pesticides and chemical fertilizers which damage the environment. The objective of this paper is to review the ecological implication of floriculture industries on surrounding environment. Environmental implication of floriculture involved the intensive use of water as well as soil, the water, and air pollution because of its intensive and toxic chemical usage and waste disposal system of the industries. The flower industry uses, 90% of groundwater resources. As planting media 40% uses soil bed, hydroponics 30% and the rest 30% also used both planting media. The waste is discharged directly to the water body by 30% of the farm, and 40% are a drain to the land. The land use change is also visible, 30% of the farm is established on local farme...

However, scarcity of high yielding varieties as well as lack of superior planting material seriously constrains productivity of the crop. Research project was initiated aiming at studying adaption of true seed shallot for yield and components. A series of experiments were conducted using the randomized complete block design to identify the appropriate variety for production of bulb yield. The combined analysis of variance results for marketable bulb yield (kg/plot), unmarketable bulb yield (kg/ha), total bulb yield (kg/plot) and total bulb yield (t/ha). The results showed that the mean squares for main factors of genotype and year as well as interaction of genotypes x year were significant for marketable bulb yield (kg/plot). The overall marketable yield range of the shallot varieties was from 256.56- 171.49qtha-1 and the a...

The study was initiated to assess the performance of haricot bean cultivars in relation to growth parameters and to estimate the analysis of growth characteristics. The experiment was conducted during November 2016 up to January 2017 at the compound of Hawassa University in the College of Agriculture during of season. The treatment consists of three Haricot varieties namely; Hawassa Dume, Omo-95 and Red Wolayta were used for test. The experiment was arranged in RCBD with four replications. The data were collected are Days to 50% emergence, Leaf area (cm2), Stem and leaf dry weight (gm) and calculated on Specific leaf area, leaf area ratio, net assimilation ratio and relative growth rate and Biomass dry weight were collected. Analysis of variance showed that the collected data were significantly different with respect to varieties. From the result in terms of (specific leaf...

To identifying adaptable coffee varieties that could exhibit higher yield to maximize coffee production and productivity to the environments of mao-komo special distinct, western Ethiopia, in order to diversify their production and to maximize the income of the farmers in the area. Based on this fact, a field experiment was conducted using six released coffee varieties, arranged with a randomized complete block design with three replicates to select varieties which could exhibit relatively better performance at the area. Those varieties were planted at a spacing of 2 m by 2 m between plants and rows, respectively and were evaluated for yield and yield components. They were grown with shade of Susbaniasusben. From the evaluated varieties it was noted that parameters as plant height, height up to primary branch, internodes length on main stem, canopy diameter, clean coffee yield had significant difference (p<0.05) among the varieties and the highest clean Coffee yield (1392.9, 1338.5 and 1100 Kg ha-1) was scored by the 75227, 7440 and F59 varieties respectively. On the contrary 74110 exhibited least mean yields of 860.1 Kg of clean coffee per hectare. Based on the yield performance 75227 and 7440 varieties were recommended to producers of coffee at Mao-komo area and demonstration needs to be investigated.

This may also lead to them delaying or dropping out of school when the combination of being a caregiver and their education program are too demanding. This survey study aims to explore the consequences for students of bachelor or vocational education programs when they are growing up with a chronically ill family member and the influence of various background characteristics and risk factors. Methods: A survey was sent to 5997 students (aged 16-25 years) enrolled in bachelor or vocational education programs in the north of the Netherlands. The content of the survey was based on a literature study and consultation with experts. Descriptive statistics, Chi-square tests, and logistic regression analyses were performed. Results: A total of 1237 students (21%) responded to the survey. A sub group of 237 (19%) students (mean age 21(2.2); 87% female) identified themselves as growing up with a chronically ill family member. More than half (54.9%) of these students indicated that they experienced negative consequences in daily life. A significant association (OR .42, p < .02) was found for these consequences and the level of education for which attending vocational education yields a higher risk. In addition, growing up with a mentally ill family member was associated with a 2.74 (p = .04) greater risk of experiencing negative consequences in daily life compared to students living with a family member with a physical disorder or multiple disorders. Conclusion: Since a substantial number of students growing up with a chronically ill family member indicate serious physical, mental, and social consequences as a result of this care situation, awareness for this specific agegroup is needed. Students with a mentally ill family member and students undertaking vocational education appear to be especially at risk. Further research is required in order to gain insight that is more in-depth into the exact type of problems that these students encounter and the specific needs that they have regarding support.
