A field experiment to evaluate blended fertilizer types and validation of soil fertility map based on fertilizer recommendation was conducted at 10 sites on-farmers’ fields in Lemu Bilbilo and Asasa districts during 2014 and 2015 cropping seasons. The experiment was conducted to compare the effects of multi-nutrient blends that included macro- and micro-nutrients (N, P, K, S, B, and Zn) among each other and against the conventional N and P rate recommendation from Urea and DAP fertilizers. The experiment consisted of six treatments viz. recommended NP and five different types of blended fertilizers laid out in randomized complete block design (RCBD) with three replications. The P and S containing fertilizers were drilled along seed line at planting while N was split applied in such a way that half was applied at planting and the remaining half was applied at tillering stage. All management practices in respect of sowing, seed rate, weed control, pest and disease control were done according to agronomic best practices. Combined analysis over locations and years indicated that wheat grain yield, test weight and hectoliter weight were not significantly increased by blended fertilizer application at both Lemu Bilbilo and Asasa areas. The highest wheat grain yield of 4694 kg/ha and 4286 kg/ha were recorded from application of recommended rate of fertilizer at Lemu Bilbilo and Asasa, respectively.

Response of Guava (Psidium guajava L.) trees of six years old planted on clay loam soil to farm residues compost , Humic acid or Humic either alone or together and supplemented with the half dose of traditional chemical fertilizers was studied during 2010 and 2011 seasons. The obtained results indicated that organic fertilizers supplemented with the half dose of traditional chemical fertilizers (1.75 kg ammonium sulphate 20.6% N, 0.75kg Potassium sulphate 48% K2O and 0.75 kg calcium super phosphate 15.5% P2O5 per tree) significantly increased tree fruiting and improved fruit physical and chemical quality characteristics. Also, leaf area, dry weight and NPK content of leaves were increased, as well as shoot length and thickness. The treatment of 4 kg compost associated with 20 gm Humic acid in combination with the half dose of traditional chemical fertilizers per tree was superior to other treatments, while organic fertilizers without chemical fertilizers exerted low effect.

Carrot is the most important root vegetable of Apeaceae families and it is cultivated in many parts of the world. Its production is increasing from time to time mainly due to its ease of production, and the increases in small-scale rain fed and irrigation areas. However, the production level is too low according to its potential. This is due to the case of poor Agricultural practice including spacing. Plant spacing is one of the important factors for the increased production of carrot. The objective of this review articles was to review the growth and yield response of carrot to intra row spacing. Different researchers reported that different plant spacing, have different effects for the growth and marketable yield of carrot concerning the ecology of area. So based on different scholars reports carrot plants have different response for different plant spacing ranging from 5 cm up to 7.5 cm intra row. Therefor investigation of the effect of plant spacing on carrot yield and yield component on different agro ecology is mandatory.

In the A field experiment was carried out to determine the effects of varying concentrations of Moringa oleifera leave aqueous extract on growth, yield and control of insect Podagrica spp. The experiment was set up in a Randomized Complete Block Design (RCBD) consisting of five treatments replicated three times. The varying treatment concentrations were; 1:10, 1:20, 1:30 and 1:40. Okra seeds of Clemson spineless variety was planted at a spacing of 60 cm by 30 cm. Plant growth parameters of plant height, stem girth, leaf area and number of leaves were taken at 1, 2, 3, 4, 5 and 6 weeks after bio-pesticides application while yield parameters of number of fruits and pod analysis were taken at harvest with harvesting carried out at four days intervals. Insect count was observed at 1, 2, 3, 4 and 5 weeks after bio-pesticides and percentage defoliation of leaves evaluated. It was observed during the experiment that plant height and stem girth did not show significant differences in the mean value of treatments at 1 and 2 weeks after bio-pesticides application (WAB) while at 3 to 6 WAB, the differences became evidence with treatment 1:30 and 1:40 having significantly higher mean values. Plots treated with 1:30 and 1:40 had significantly higher fruit numbers. The yield in kg/ha also shows significantly higher mean values with treatment concentrations of 1:30 and 1:40 and the control having a low yield. Also, treatment concentration of 1:30 and 1:40 had significant control effect on the population of Podagrica spp and therefore gave lowered percentage defoliation. The different concentration of Moringa oleifera leave aqueous extract had significant control effect on insect Podagrica spp.

In the present experimental study, we evaluated some tomato cultivars in greenhouse and field conditions in order to determine superior cultivars for yield and yield component traits. The experimental lay out adopted was the Randomized Complete Block Design (RCBD) which was replicated three (3) times. The combined analysis of variance showed significant (p<0.01 and p<0.05) variability among the genotypes, locations and genotype-location interactions (G × L) for almost all the traits. The relative performances of the genotypes differed with location. Among the genotypes evaluated, Mongal F1, Platinum F1, Nkansah HT, Wosowoso, Roma and Sumo F1 displayed superior performance for fruit yield across all locations

Togo’s semi-deciduous forest zone has a great diversity of plants and ecosystems that constitute a natural heritage that should be well studied for sustainable and efficient management. Thus, the main objective of this study is to determine the environmental factors responsible for the vertical stratification of Orchidaceae epiphytes. This study investigated the diversity of these epiphytes and their hosts in the semi-deciduous forest zone of Togo. A habitat characterization of these epiphytes has been done to define the adaptive strategies of these species to their natural environment. The floristic inventory identified 37 species of Orchidaceae and 50 species of phorophytes. These epiphytes are found particularly at 36.36% in position IV and 26, 46% in position V on phorophytes. Perceived luminosity, moisture content and anthropogenic pressure are the indicators responsible for the dispersion of Orchidaceae epiphytes according to different positions on phorophytes. The inventoried phorophytes are 40% mesophanerophytes and the megaphanerophytes represent only 27%. The chorology of phorophytes indicates a high proportion of introduced species represented at 20% and rank second behind those of Guinea- Congo which are represented at 49%.

Okra and water spinach are traditional vegetables that are vital for healthy diets. Major variations in germination response have been observed among genebank entries. This study was undertaken to elucidate the effect of various seed treatments on the germination of fresh and stored seed of okra and water spinach. Freshly harvested fruits of two okra and two water spinach accessions with contrasting geographical origin and breeding status were dried in a screenhouse prior to manual seed extraction and cleaning. Cleaned seeds were dried to 6% seed moisture content in a dehumidified drying room. Various seed treatments were conducted after a 6-month storage period at 5oC and -15oC. Our studies confirmed previous results that both okra and water spinach are difficult to germinate and to obtain good field establishment due to physical, seed coat-imposed dormancy. Moreover, significant genotypic variation among genebank entries/cultivars was found for both crops, making germination response difficult to predict. Improved varieties showed much better germination response than landraces and did not require seed treatments for satisfactory germination. Hydropriming, i.e. soaking of seed in water for 24 hours, did not have an impact on seed germination. Partial removal of the seed coat, followed by 24 hours soaking in water consistently resulted in high germination percentages (>80%) of genotypes of both crops that had not undergone dedicated breeding (landraces), under laboratory and screenhouse conditions and during two subsequent growing seasons. When distributing seed samples of semi-domesticated accessions or landraces, genebanks should advise seed recipients that scarification methods may be necessary to obtain satisfactory seed germination and field establishment.

This investigation had been implemented for checking Osmanthus fragrans Resources. In this paper, 29 classified characters were selected based on our preliminary research foundation of O. fragrans in Jingzhou city parks, then O. fragrans quantitative classification of 24 cultivars was carried out by SPSS analysis. The results showed principal component contribution rate was scattered, which is not an ideal method for quantitative classification of O. fragrans cultivars. The method of Walder was the best among seven clustering methods. The clustering results showed that there was a long relationship between autumn Osmanthus and Asiaticus Group. In addition, flowering season, flower color and fertility were very important for O. fragrans cultivars classification. The evolution of O. fragrans petals color might be complex and multi-way. The O. fragrans cultivars classification should not be too entangled with their color, but mainly based on flowering date. The comprehensive evaluation of inflorescence type, flower color, leaf color and other morphological characteristics played necessary reference role for the traditional variety classification method and the modern quantitative classification method.

Copper ions at proper levels are essential for plant cell growth and excess copper ions are toxic to root cell growth. The one meter height Theobroma cacao L. plants have roots in 10-15 cm depth nursery pots. “SpinOut®” high in Cu+2 and painted inside the plastic container mitigates against root encircling. Evidence is presented that a similar physicochemical effect can be obtained by incorporating copper ions into a keratin biopolymer matrix extruded into pellets and injection molded into a pot. Sustained controlled release of Cu+2 is obtained for at least six months. The same technology enables highly uniform delivery of the same amount of micronutrients self-consistently pot to pot. This approach would be useful in urban agriculture in which the biomass formulated composition of a soil matrix is especially non-uniform and in which both the plant and the surrounding soil matrix can be competing from among the same micronutrients.

This approach would be useful in urban agriculture in which the biomass formulated composition of a soil matrix is especially non-uniform and in which both the plant and the surrounding soil matrix can be competing from among the same micronutrients.","PeriodicalId":15920,"journal":{"name":"Journal of Horticulture","volume":"1 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88867214","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}

Alternative splicing (AS) produces multiple mRNA splicing variants from a single precursor transcript. Recent genome sequencing analyses and increasing experimental evidence in flowering plants have revealed that AS is far more prevalent than previously thought and plays crucial roles in the diversification of gene regulation. Despite numerous studies, the extent and complexity of mRNA variants in plants remain poorly characterized from a global perspective. In present study, 589,034 mRNA variants from 442,541 annotated genes of 12 plant species were investigated. All AS genes were classified into four groups on the basis of the numbers of mRNA variants, namely, 2V (two variants), 3V (three variants), 4V (four variants), and 5V+ (five or more variants). Interestingly, our analysis indicated that more than 50% AS genes generated only two variants in higher plants. A global analysis of gene structure revealed that AS genes contained more but shorter exons and introns as the number of mRNA variants increased. The results also suggested that AS elicited different effects on the improvement of transcriptome and proteome diversity. Taken together, cross-species analysis provided the most comprehensive set of annotated splicing variants in higher plants thus far and extended the current view about mRNA variants.
