The Study was carried out at Federal Polytechnic Nekede, Student Research Farm. The Nekede soil is sandy loam textured, with pH value as low as 4.8 and very deficient in OM and N. Amelioration treatments were carried out by adding organic supplements (palm bunch ash and wood ash) to the soil. The study used a randomized complete block design with 10 t/ha palm bunch ash (PBA), 10 t/ha wood shave ash (WA), 5 t/ha PBA + 5 t/ha WA and a control (no additives added), making a total of four treatments. The treatments were replicated three times. The experimental works were undertaken in field plots. The growth parameters examined were: Plant height, leaf number and vine length and shoot/root ratio, fresh weight. Data collected were subjected to statistical analysis using least significant difference (LSD). Results of the studies showed that sole application of 10 t/ha PBA and 10 t/ha WA and halved their rates in combination, increased soil pH, N, OC, P, K, Ca and Mg in relation to the control treatment. Combination of palm bunch ash (PBA) and wood ash (WA) significantly enhanced yield in fluted pumpkin (Telfairia occidentalis). The study reveals that soil acidity could be neutralized; soil fertility improved and crop yield enhanced with a combination of organic amendments on the ultisols of south-eastern Nigeria.","PeriodicalId":260376,"journal":{"name":"Global Journal of Agricultural Research","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114184029","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}

Four experimental diets were formulated such that the diets contained pearl millet (T2), Finger millet (T3, Douro millet (T4) and the control diet (T1) contained maize. The diets were fed to Four hundred and eighty (480) Anak 2000 strain day old broiler chicks in a 56 days feeding trial. The diets were randomly assigned to four groups of 120 birds in a completely Randomized Experimental Research Design (CRD) replicated 3 times with 40 birds per replicate. Feed and water were provided ad libitum. The results obtained showed no significant differences (p<0.05) in all the parameters measured on haematological parameters. The serum biochemical indices showed that total protein (22.67-34.00), albumin (9.67-15.00), urea (0.23-0.96), creatinine (21.33-35.00), cholesterol (1.70-2.38) were significantly (p>0.05) affected by the experimental diets. Althogh, the values for glucose (9.56-9.86) and bilirubin (7.5-9.43) were statistically similar. It was concluded that Dauro and finger millet varieties can favorably replace maize in broiler diets without adverse effects on blood haematology and biochemistry of broiler chickens and thus, will help reduce the cost of broiler production especially for farmers in the millet production areas.","PeriodicalId":260376,"journal":{"name":"Global Journal of Agricultural Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129702854","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, some of the local varieties have become almost extinct; this calls for the need to revive interest in these crops. This study was undertaken to characterize six cocoyam accessions collected from Cross River and Akwa Ibom States, Nigeria, using 13 qualitative and 6 quantitative Agro-morphological descriptors as well as simple sequence repeat (SSR) primers. The crops were laid out in a field using the Randomized Complete Block Design (RCBD) in 4 replications. Analysis of variance (ANOVA) test showed that the 6 accessions were not significantly different (P>0.05) in crop span, crop height, number of leaves, leaf width and leaf length. This indicates that these features cannot be used to distinguish between Colocasia and Xanthosoma spp. The qualitative traits were more useful in distinguishing between the two cocoyam species. Three of the primers used for molecular studies successfully amplified a few of the cocoyam accessions, indicating their suitability for genetic diversity studies in Colocasia esculenta and Xanthosoma spp.","PeriodicalId":260376,"journal":{"name":"Global Journal of Agricultural Research","volume":"692 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132234899","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 aimed to determine the residual effect of lime and P fertilizer on the acid properties of soils and to develop models whereby the change in acidity indicators of soils can be predicted as a result of lime application. The experiment was laid out in a randomized complete block design with three replications. Five levels of lime (0, 1.15, 2.3, 3.45, 4.6 t ha-1) and four levels of Phosphorous (0, 10, 20, and 30 kg ha-1) were combined in a complete factorial arrangement. The study was conducted for three consecutive years from 2015 to 2017 main cropping seasons at Banja district. Mean grain yield and yield components as affected by different levels of lime and phosphorus fertilizer. Analysis of variance showed that all limed treatments were higher mean values of grain yield and yield components relative to control plot (no lime and P) in all over combined cropping years. Moreover, over year combined mean the highest grain yields (1115.9 kg ha-1), biomass yields (3591.2 kg ha-1), number of seeds per plant (21.54), plant height (64.50 cm) and spike length (5.24 cm) were recorded under 4.6 t ha-1 of lime application of plot. The lowest grain and biomass yields were recorded in control plots. However, over year mean 4.6 t ha-1 of lime application plot the grain yield and biomass yield of wheat were increased by (151.1%) and (123.3%) related to the control plot, respectively. Hence, lime application at the rate of 3.45 t ha-1 (150% of the lime requirement of the soils based on its exchangeable acidity) coupled with 20 kg ha-1 P fertilizer could serve as a reference to boosting wheat production in the study area and similar areas with possible re-liming of the soils in every five years.","PeriodicalId":260376,"journal":{"name":"Global Journal of Agricultural Research","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128309952","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}

However, to improve palatability and organoleptic qualities, most grains undergo further processing to yield better product, this processing includes dehulling, winnowing which may alter the nutritional composition of the resultant products to varying degree. The present study investigated the effect of dehulling on mineral content of cereals. Mineral elements composition in the undehulled and dehulled millet were: potassium (18.89 and 18.91) mg/kg, magnesium (14.13 and 14.26 mg/kg), calcium (44.12 and 48.15 mg/kg), zinc (5.28 and 5.33 mg/kg), iron (5.64 and 5.82 mg/kg) and copper (18.00 and 18.00 mg/kg) respectively. Undehulled and dehulled guinea corn were: potassium (17.45 and 15.29 mg/kg), magnesium (15.22 and 14.32 mg/kg), calcium (40.14 and 34.14 mg/kg), zinc (4.45 and 4.04 mg/kg), iron (4.49 and 5.37 mg/kg) and copper (17.02 and 18.48 mg/kg) respectively.

This review was intended to collect research works on white mango scale with special focus on research works done in Ethiopia. Different findings of research works on the insect were carefully studied. The white mango scale insect, Aulacaspis tubercularis (Hemiptera: Diaspididae) is a recent threat to mango production in Ethiopia which was introduced the first time in 2010 in western part of the country. It has spread to all mango producing areas of the country within a short period of time reducing the production and quality of mangos. Control measures taken against the white mango scale include use of chemical insecticides, quarantine, cultural practices, biological control using parasitoids and predators and integrated pest management. Quarantining the insect is the management method recommended in many cases. Generally, the current reports revealed that mango production in Ethiopia will be under serious threat which can even destroy total mango production in the future.","PeriodicalId":260376,"journal":{"name":"Global Journal of Agricultural Research","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116469375","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}

It takes advantage of genetic variation among individuals within a plant species and combines desired traits to produce new and improved varieties. Plant breeding depends on genetic variety, and new variation is critical for introducing interesting characteristics into breeding programs. Genetic erosion is a term used to describe the loss of variation in crops as a result of agricultural modernization. Plant breeding has had a significant impact on food production and will continue to play an important role in ensuring global food security. Plant breeding can be broadly described as changes in plants caused by human use, ranging from unintended modifications generated by the introduction of agriculture through the use of molecular tools for precision breeding. Plant breeding based on observed variation by selection of plants based on natural variants appearing in nature or within traditional varieties; plant breeding based on controlled mating by selection of plants presenting recombination of desirable genes from different parents; and plant breeding based on monitored recombination by selection of specific genes or marker profiles. Continuous use of traditional breeding methods in a given species may reduce the gene pool from which cultivars are derived, making crops more susceptible to biotic and abiotic challenges and impeding future advancement. Plant breeding's primary objectives are 'high yield, high quality, and quantity, extension of climate and soil adaptability ability, and tolerance or resistance to pests and diseases.' Plant breeders achieve these goals by exploiting genetic differences between plants. The range of the genetic base, as measured by genetic diversity, is a limiting factor in successful adaptation to environmental conditions and plant breeding. Many challenges in plant breeding require genetic variation, which can be found in the biodiversity of plant genetic resources such as breeding lines, landraces, primitive forms, wilds and wild relatives, and weed races.","PeriodicalId":260376,"journal":{"name":"Global Journal of Agricultural Research","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134630526","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}

These physiological responses are triggered by the fluctuation of endogenous ABA levels in accordance with changing surroundings or developmental stimuli. Endogenous ABA levels are largely controlled by the balance between biosynthesis and catabolism. ABA is produced by cleavage of a 40-carbon carotenoid precursor that is synthesized from isopentenyl diphosphate via the plastid terpenoid pathway. ABA is synthesized in almost all cells that contain plastids and is transported via both the xylem and the phloem. ABA in tissues can be measured by bioassays based on growth, germination, or stomatal closure. Abscisic acid plays primary regulatory roles in the initiation and maintenance of seed and bud dormancy and in the plant’s response to stress, particularly water stress.","PeriodicalId":260376,"journal":{"name":"Global Journal of Agricultural Research","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116650134","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}
