A rigorous random selection process was used to pick 480 households from cross-sectional data. For this investigation, both primary and secondary data were used. Stata version 16 was used to examine both qualitative and quantitative data using descriptive (mean, standard deviation, and percentages) and econometric (three-stage least square technique) analyses. According to the descriptive data, the majority of respondents used their remittances for consumption, to acquire agricultural inputs, and to pay back their debts and tax payments. According to econometric studies, rural-urban migration has little influence on agricultural productivity. Remittances, cultivated land, livestock ownership, and extension services, on the other hand, have a positive and significant effect on agricultural productivity. In a nutshell, the link between migration, remittances, and agricultural output in agrarian and rural families is remarkable. Agriculture is the major source of income and mostly handles the liquidity issue. Agriculture production in the study region is labor intensive, and it is influenced by the amount of effort utilized in production as well as the socioeconomic characteristics of the household. As a result, it must address the major conundrum of agricultural productivity, particularly rural-urban migration and remittances. Address a knowledge gap, begin activities, and develop and implement multiple initiatives by various responsible stakeholders that are essential for the research topic. Furthermore, agricultural extension service delivery should be improved by timely recruiting, frequent agent training, and appropriate logistics.","PeriodicalId":30608,"journal":{"name":"Advances in Agriculture","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88453536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the objective of this study was to evaluate selected cowpea genotypes for herbage dry matter yield and nutritional quality in two agro-ecologies of the Benishangul-Gumuz region. The study was conducted at Kamashi and Assosa forages research stations of Assosa Agricultural Research Center, and the sites were purposively selected to represent lowland and midland agro-ecologies, respectively. Four cowpeas’ accessions (V. Unguiculata ILRI-11114, ILRI-12688, ILRI-12713, and ILRI-9333) and one check (Melka (ILRI-9334) as a check) were evaluated in a randomized complete block design with three replications. Herbage dry matter yield, plant height at forage harvesting, and days to maturity were significantly affected by location (L). Longer plant heights, shorter days to maturity, and higher dry matter yield (\u0000 \u0000 P\u0000 <\u0000 0.001\u0000 \u0000 ) were recorded at Kamashi than at Assosa. Herbage dry matter yield was significantly \u0000 \u0000 P\u0000 <\u0000 0.05\u0000 \u0000 affected by year (Y), Y\u0000 \u0000 ∗\u0000 \u0000 L (Y and L interaction), G\u0000 \u0000 ∗\u0000 \u0000 L\u0000 \u0000 ∗\u0000 \u0000 Y (genotype (G), L and Y interaction), and G\u0000 \u0000 ∗\u0000 \u0000 L. Hebage dry matter yield was similar between years at Assosa, whereas at Kamashi significantly (\u0000 \u0000 P\u0000 <\u0000 0.001\u0000 \u0000 ) different and more yields were obtained in 2015. The genotypes did not differ in nutritional quality parameters such as ash, acid detergent fibre, crude protein, and organic matter digestibility (\u0000 \u0000 P\u0000 >\u0000 0.05\u0000 \u0000 ). However, neutral detergent fibre and acid detergent fibre were significantly (\u0000 \u0000 P\u0000 <\u0000 0.05\u0000 \u0000 ) influenced by genotype.

Estimating genetic parameters are momentous in deciding breeding method to be followed for crop genetic improvement including Arabica coffee. The study was conducted with the intention to gauge genetic gain trend in coffee yield and to select advanced promising lines of Yayo coffee landrace for the next breeding step. The study was laid down at Metu research subcenter in 2013, using 124 coffee accessions that were established in simple lattice design under two sets each comprising 62 accessions including two checks. The over six year’s pooled analysis of variance indicated the handiness variability in yield performance among accessions. Moderate genotypic variance (15.46 to13.56%), heritability (56.16–81%), and expected genetic gain (15.52–20.8%) were observed. The genetic parameters and the superiority of check in yield over accessions elucidated that high yielder variety development by selection is difficult unless heterosis attaining breeding method followed, particularly for these Yayo coffee landrace origin. Common high genetic gain trend (49.19 and 100 kg·ha−1) and response to selection (196.76 and 400 kg·ha−1), selection differential 471.9 and 739.23 kg·ha−1 were revealed in over four harvesting seasons mean value for both sets. Thus, selection is more effective in earlier season than late. High yielding accessions, Y27 and Y93, gave 3013.1 and 125.8 kg·ha−1 yield gain over the high yielder check correspondingly. Despite the top 15 and 10 high yielders were selected from set-I and set-II, respectively, a total of 20 accessions with contrasting desirable traits were selected and established in crossing block for genetic improvement purposes via heterotic hybrid variety development program.

It is highly susceptible to insect pests and microbial pathogens. The tomato leafminer moth, Tuta absoluta Meyrick, is the current impediment to tomato production in the world. The insect showed invasive and notorious behavior and was affecting tomato production. To control this insect, the application of synthetic insecticides is seen as the primary solution. However, during the feeding stage, larvae hide within mined leaf mesophyll and bored fruits from chemical spray, besides fast developing resistance to several insecticides. Such characteristics of the insect reduced the effectiveness of the chemical control efforts. Currently, the natural, or ecofriendly pest control method is gaining the momentum to minimize the application of synthetic insecticide against this devastating insect. Studies showed that botanical extracts (phytochemicals) and natural enemies such as parasitoids, predators, entomopathogenic nematodes, entomopathogenic fungi, and entomopathogenic bacteria are effective for controlling T. absoluta. As a result, the basic attributes of the above-mentioned natural agents and their potential to control T. absoluta have been briefly discussed in this review. However, due to disease (pests), the expected outcome for the subsectors is still low. Therefore, the pinpointing of major diseases and pests and their control measures would help to significantly improve the crop production technology used by smallholder farmers and thereby sustainably improve tomato production in Ethiopia.","PeriodicalId":30608,"journal":{"name":"Advances in Agriculture","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91216982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The bread wheat production in Ethiopia is low compsssared to the national average yield, mainly due to the lack of high-yielding genotypes. This study was conducted during the 2019-2020 growing season to assess genetic variability and estimate the association of traits among bread wheat genotypes. The experiment consists of 49 bread wheat genotypes and is laid out in 7 × 7 simple lattice designs. The results showed significant differences (\u0000 \u0000 p\u0000 \u0000  < 0.01) among genotypes for most of the studied traits. Moderate genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) values were estimated for yield plant −1, thousand seed weight, and biomass yield. High heritability coupled with a high GAM was observed for thousand seed weight and yield plant –1. The grain yield showed a highly significant (\u0000 \u0000 p\u0000 \u0000  < 0.01) correlation with many yield-related traits at the phenotypic and genotypic levels. The biomass yield and the harvest index exerted the highest positive direct effect on grain yield at the genotypic level. The highest intercluster distance was observed between clusters I and IV (D2 = 31.86\u0000 \u0000 \u0000 \u0000 \u0000 ∗\u0000 ∗\u0000 \u0000 \u0000 \u0000 ), followed by clusters II and IV (D2 = 29.21\u0000 \u0000 \u0000 \u0000 ∗\u0000 \u0000 \u0000 ), and clusters II and III (D2 = 28.24\u0000 \u0000 \u0000 \u0000 ∗\u0000 \u0000 \u0000 ), which indicated the chance of selecting a member of these clusters for hybridization. This experiment’s result indicates sufficient genetic variability among the tested genotypes, which provides ample scope for selecting superior and desired genotypes. Best-performed genotypes should be included in the future breeding program for further yield improvement. In conclusion, attention should be given to traits with moderate to high heritability and GAM, exerting a positive direct effect on the grain yield.

Nonetheless, the sector keeps on confronting production challenges as a result of frequent and extended droughts, and these necessitate the use of drought-resistant crops such as sorghum. This review initiates one of the most common food grains grown in the poorest countries and the most food-insecure regions of the nation. We used deductive logical reasoning to develop a comprehensive scientific understanding of the crop that can be used to inform future research and policies. Various exclusion and inclusion criteria were used to filter the most prominent findings. Sorghum has the highest utility for its climatic adaptability and has grown for multiple purposes: From staple to industrial outcomes, its economic, social value, and health outcomes, and for animal silage. It is a gluten-free crop, has high nutritive value, and is preferred by healthy consumers. It is among the top five cereal crops worldwide in both production and acreage. This has necessitated the development of coping measures, such as the cultivation of drought-tolerant crops suitable for the affected areas. Therefore, this crop is used to ensure productivity, food security, and availability of food when other crops fail and food deficit and famine are affected in the region. This will contribute to the ongoing discussion on how to better inform private and public sector policy and investments in Ethiopia to increase sorghum and other drought-tolerant crop production, transform agriculture, improve nutrition, and food systems, and end hunger, food insecurity, and poverty.","PeriodicalId":30608,"journal":{"name":"Advances in Agriculture","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75737750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The treatments consisted of a factorial combination of two varieties (Jalenie and Gudenie): five levels of tuber size (20–35, 36–50, 51–65, 66–80, and 81–95 g) and five levels of intra-row spacing (20, 25, 30, 35, and 40 cm). The treatments were arranged in a split-split plot design (variety on main plot, intra-row spacing on subplot, and tuber size on sub-sub plot) with three replications. There were significant interaction effects of variety, intra-row spacing, and tuber size (\u0000 \u0000 P\u0000 <\u0000 0.05\u0000 \u0000 ) on plant height, number of main stems per plant, average tuber weight, tuber number per plant, total tuber yield, marketable tuber yield, unmarketable tuber yield, large tuber mean yield, medium tuber mean yield, and small tuber mean yield. Variety of tuber size and intra-row spacing was also influenced by dry matter content and tuber specific gravity. The interaction effect of intra-row spacing and seed tuber size was significantly (\u0000 \u0000 P\u0000 <\u0000 0.05\u0000 \u0000 ) influenced by the number of days to emergence. The day to flowering was also significantly (\u0000 \u0000 P\u0000 <\u0000 0.05\u0000 \u0000 ) influenced by the interaction effect of variety and intra-row spacing. The maximum plant height (80.38 cm) was recorded with variety Gudenie with a tuber size of 66–80 g and planted at an intra-row spacing of 35 cm. The maximum (9.79) number of main stems was recorded in variety Jalenie with a tuber size of 81–95 g and planted at intra-row spacing of 40 cm. The maximum of total tuber yields (24.84 to/ha) was recorded from Jalenie variety with tuber size 66–80 g and planted at intra-row spacing of 25 cm. The maximum (10.18 t/ha) larger tuber was recorded with variety Gudenie with a tuber size of 66–80 g and planted at 25 cm. Variety Jalenie with tuber size of 66–80 g and planted at 25 cm produced the maximum (8.04 t/ha) medium-sized tubers. The maximum small tuber (8.59 t/ha) was recorded from both varieties with intra-row spacing of 20 cm and tuber size 81–95 g. Variety Gudenie planted at intra-row spacing of 40 cm gave higher (19.98%) dry matter content, and variety Gudenie with a tuber size of 66–80 g gave higher (20.61%) dry matter content. The higher (1.077) tuber specific gravity was obtained with variety Gudenie planted at intra-row spacing of 35 and 40 cm, and the higher (1.074) tuber specific gravity was registered with variety Gudenie with a tuber size of 66–80 g and/or 81–95 g and planted at intra-row spacing of 40 cm.

However, due to abiotic and biotic stresses, its productivity is low as compared to the world average. Among these, soil fertility and unbalanced application of plant nutrients are the major constraints that limit the productivity of the crop in sub-Saharan African countries especially Ethiopia. As a result, an experiment was carried out at the Gitilo Dale Research Site of Wallaga University to determine the combined impact of blended NPSB and urea fertilizers on the growth, yield, and yield-related variables of bread wheat. The experiment used a factorial-arranged in randomized full block design with two factors with four levels each: NPSB (0, 100, 150, and 200 kg·ha−1) and nitrogen (urea) (0, 31.1, 71.65, and 112.2 kg·ha−1) (RCBD). With three replications, there were sixteen treatments. A test crop of the bread wheat variety liben (ETBW 5653) was grown. The phonological and growth parameters of bread wheat were significantly affected by NPSB and nitrogen applications as well as their interactions except for days to 50% emergence. The primary and interaction impacts of NPSB and nitrogen rates affected the yield and all of its constituents, except the number of kernels per spike. The application of 200 kg·ha−1 NPSB plus 112.2 kg·ha−1 nitrogen treatment resulted in the highest above-ground biomass production of bread wheat (12481.00 kg·ha−1), grain yield of 5182.51 kg·ha−1, and a straw yield of 7298.40 kg·ha−1. Hence, to maximize the yield of bread wheat, applying 200 kg·ha−1 of chemically blended NPSB with 112.2 kg·ha−1 nitrogen is recommended rather than applying any straight and complex fertilizers having only macronutrients.","PeriodicalId":30608,"journal":{"name":"Advances in Agriculture","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88445361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
