The experiment was carried out at the research field of the Department of Crop Science and Technology, Rajshahi University, Rajshahi during the period from November, 2021 to March, 2022. The experiment consisted of three spacing i.e. 50cmX30cm, 50cmX40cm and 50cmX50cm as well as three levels of nitrogen fertilizers viz. 50kg/ha, 100kg/ha and 150kg/ha. The results revealed that different treatments significantly affected the growth and yield attributes of cabbage. The combination of wider spacing (50cmX50cm) combination with highest level of nitrogen fertilizer (150kg/ha) produced the maximum plant height, no. of leaves per plant, largest leaf length, largest leaf breadth, head diameter, head thickness, individual head weight and yield whereas50cmX30cm spacing and lowest level of nitrogen fertilizer (50kg/ha)required maximum days required for head maturity. On the other hand, all the studied parameters except days required for head maturity found to be lowest in the treatment combination of 50cmX30cm spacing with lower level of nitrogen fertilizer (50kg/ha).The study concluded that cabbage need to be cultivated at 50cmX50cmspacing and 150kg/ha nitrogen fertilizer is to be applied for getting the targeted yield as well as desired return from cabbage cultivation in “High Ganges River Floodplain zones” of Bangladesh.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207315","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}

Its infestations represent a threat to the cattle industry since they generate a negative economic impact on cattle production and animal welfare. The method par excellence for tick control is based on applying chemical agents. However, their use has had limited efficacy, often accompanied by environmental contamination and the selection of tick’s resistant to most chemical agents, rendering them ineffective. One of the alternative methods to combat R. microplus infestations is the development of vaccines. Two commercial vaccines are based on the Bm86 antigen, TickGARD®, and Gavac®. However, the efficacy is highly variable between different geographical regions. While it is true that other alternatives have been tested, the search for vaccine antigens that provide high protection against R. microplus remains a challenge in which genomic, transcriptomic, and proteomic studies are required. This review briefly summarizes the current situation regarding the discovery of candidate antigens for vaccines against ticks in cattle, as well as the methodologies employed for their search and development.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"113 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207100","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}

Therefore the aim of the study is to assess the responsiveness of maize varieties to four rates of nitrogen fertilization in the formation of grain yield and other agronomic traits. The study area was at the Teaching and Research Farm of Ladoke Akintola University of Technology, Ogbomoso, Nigeria. The test period was between 2021 and 2022 where six varieties of maize (sub-plot factor) were included in an experiment with four rates (0, 30, 90 and 150 kg N/ha) of nitrogen fertilizer (main plot factor) laid down in a randomized complete block design with six replicates. Analysis of variance indicated that there were significant (P < 0.01) differences among maize varieties, nitrogen fertilizer rates, variety × year interaction as well as between the years of evaluation for grain yield and other agronomic traits. Growth parameters and grain yields differed significantly (P < 0.05) between varieties at all nitrogen fertilizer rates. SC 719 produced the highest yield (2512.03 kg/ha), whereas the lowest yield (1721.41 kg/ha) was found in SAMMAZ 27. The shortest anthesis-silking interval (2.4 days), lowest ear aspect score (4.9), highest grain yield (2734.6 kg/ha), plant (167.3 cm) and ear (72.3 cm) heights was recorded from plots fertilized with 150 kg N/ha. All the maize varieties performed better than the widely grown adapted local check (Oba super 6) under 0 kg N/ha. The application of nitrogen fertilizer improves yield and other agronomic traits of the maize varieties. Treatment of 90 kg N/ha gave comparable performance with 150 kg N/ha for most traits. Moreover, judicious nitrogen fertilizer management could ensure high grain yield production and profit.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207312","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}

This study was carried out to understand the genetic nature of yield and its components on which selection can be made. The seed of each accession was sown in a plot laid out in randomised complete block design with three replications. Data were collected on fifteen agronomic characters and analysed. The magnitude of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were highest for number of pods and lowest for number of days to germination respectively. The PCV was moderately higher than GCV in most of the traits studied, which indicated that environment played a little role in the expression of these traits. Low heritability was recorded for number of leaves and number of branches which indicated more influence of environmental effect, which may be due to the presence of non-additive gene action in the expression of the traits. High heritability and high genetic advance as percent of mean were recorded for plant height at flowering, days to 50% flowering, plant height at maturity, internode length, number of pods and days to maturity, indicating that these traits were less influenced by environment and presence of additive gene action. NGB00378A, NGB00299, NGB00304 and NGB00302 had higher fruit yields; flowered earlier, had longer harvesting period. Therefore, selection can be made on these for further improvement of this crop.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136208394","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}

In order to overcome all these issues, there is a need for advanced farming technologies for growing the most demand food crops. Smart farming also known as precision agriculture has evolved which uses the advanced technology to optimize the efficiency and productivity of the farming operations. It involves the integration of various technologies such as IoT sensors, drones, robotics and machine learning technologies, big data analytics to gather data on crop growth, environmental conditions and weather patterns. Vertical framing (VF) is one such precision framing efficient crop growth practices which adapts the integration of Internet of Things (IoT) and machine learning (ML) technologies in easier manner. Since, the vertical farming is completely an indoor farming technique, they do not depend on the particular geographical locations and outdoor growth parameters (like soil) for crop cultivation; hence, vertical farming is also known as controlled environment agriculture. This article explores the significance of different indoor vertical farming practices under controlled environment with the comparative analysis, efficiency, productivity, advantages and their potential benefits highlighting the need for sustainable agricultural practices that can meet the growing demand for food while minimizing the negative environmental impacts.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"363 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207960","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}

Appropriate farming systems and soil conservation measures are the only opportunity to reduce the high risk of crops yield losses. The aim of this study was to evaluate the effect of three farming systems; Conventional Farming (CF), Conservation Agriculture (CA), and in-field rain Water Harvesting (WH); on the yield and water productivity of sorghum, sesame and cowpea crops. Field experiments were conducted in semi-arid area of Sennar State, Sudan for two consecutive seasons (2015 and 2016). Three different planting machines were used. The CA recorded higher crop yield for sorghum (2594 kg/ha) followed by in-field rainwater Harvesting (WH) which gave 2362 kg/ha, while CF has the lowest crop yield (2072 kg/ha). For the sesame crop the WH gave the highest crop yield (740kg/ ha) followed by CA (718 kg/ha) and the lowest crop yield was obtained by CF (602 kg/ha). The highest cowpea crop yield was obtained by WH (927.kg/ha) followed by CA farming system (847 kg/ha) and the lowest crop yield was obtained by CF (785kg/ha). The CA farming system recorded the highest water productivity for sorghum (1.081 kg/m3) compared to the WH and CF, while the WH farming system recorded the highest water productivity (0.32 and 0.366 kg/m3) for sesame and cowpea respectively compared to the CA and CF. WH is best recommended farming system in semi-arid areas and CA the best recommended practice where annual rainfall is relatively high.","PeriodicalId":497825,"journal":{"name":"Open access journal of agricultural research","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136207961","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}
