Survey of plant parasitic nematodes were carried out in some sweet potato growing areas of Nigeria. The research was design to assess the plant parasitic nematode pests of sweet potato in sweet potato growing areas in Nigeria. Soil samples and sweet potato tubers were randomly sampled from selected farm sites in Oyo, Osun, Kaduna, Kwara, Kogi, Abia, Cross Rivers, Benue, Taraba and Plateau States of Nigeria. Plant parasitic nematodes were extracted from soil and sweet potato tubers following standard methods and identification key for agriculturally important plant-parasitic nematodes was used for the nematode identification. Nematodes were extracted and identified in the laboratory. The plant parasitic nematodes identified in the soil samples and sweet potato tuber were root knot nematode Meloidogyne incognita, reniform nematode Rotylenchulus reniformis, lesion nematode Pratylenchus species, brown ring nematode Ditylenchus destructor and D. dipsaci, stubby root nematode Paratrichodorus spp. and dry rot nematode Scutellonema bradys. Plant parasitic nematodes infected sweet potato tubers have unappealing appearances, cracks, internal lesions and dry rot. Keywords: Sweet potato, plant parasitic nematodes, Nigeria ...

Analysis Of Breach Of Dormancy Of Jurema Preta And Mororó

Research Article of American Journal of Agricultural Research ANALYSIS OF BREACH OF DORMANCY OF JUREMA PRETA (Mimosa hostolis Benth.) AND MORORÓ (Bauhinia cheilantha (Bong.) Steud) José Crisólogo de Sales Silva,1* Lívio Kelver Martins da Silva,2** João Paulo Silvério da Silva,3***José Iran Sousa e Silva,4 Alex Romualdo Nunes,5 1. Prof. Dr. Titular Zootecnia, Universidade Estadual de Alagoas – Santana do Ipanema / AL - Brazil 2,3,4,5. Zootechnist of Universidade Estadual de Alagoas – Santana do Ipanema / AL - Brazil; The seed dormancy limits seedling production and the potential for using them. This study aimed to determine the best method for breaking dormancy in seeds of Mimosa hostilis Benth. and Bauhinia cheilantha (Bong.) Steud. The experiment was conducted at the Laboratory of Food Science, State University of Alagoas (UNEAL) Campus II, located in the municipality of Santana do Ipanema, Alagoas State, Brazil. Five treatments were studied (T): T1 - immersion in water at 100 ° C until cooling thereof; T2 - immersion in water at 50 ° C until cooling thereof; T3 - immersion in sulfuric acid for 5 minutes, followed by washing in water for 10 minutes; T4 - mechanical scarification by sandpaper for 2 minutes, and T5 - Witness. Where it came to evaluating the germination speed index (GSI) and germination percentage (G%). Data were subjected to analysis of variance and the means compared by Tukey test at 5% significance level. The immersion in sulfuric acid was the best method to break seed dormancy of Mimosa Hostilis Benth., now for Bauhinia cheilantha bong. Steud in the chiseling was the best method for breaking dormancy. Keywords: Germination. Seeds. Mechanical scarification ...

Effect of wastewater irrigation of sweet sorghum on soil and plant

Research Article of American Journal of Agricultural Research Effect of wastewater irrigation of sweet sorghum on soil and plant  A.Almodares*1, Z. Beheshtian2 1 Biology Department, College of Sciences, University of Isfahan, Iran. 2 Former graduate student, Biology Department, College of Sciences, University of Isfahan. Iran. The experiment was conducted at Isfahan East Waste Water Treatment in 2011 growing season by using a randomized complete block design with three replications. The treatments were managed for irrigation: municipal water, untreated waste water and treated waste water. Results showed irrigation with untreated and treated waste water had significantly higher biomass (86.00 t/ha) than municipal water (66.00 t/ha). Highest ethanol yield (6540 l/ha) was obtained for sweet sorghum irrigated with raw waste water. Both pH and P was accumulated in the soil irrigated with untreated and treated waste water. At the end of growing season the amount of Cd, Pb and Ni were accumulated in these soils. The amount of measured heavy metals in sweet sorghum grain, leaf and stem were significantly higher in untreated waste water than both municipal water and treated waste water. Number of coliform in untreated waste water was significantly higher than treated and municipal water. The number of coliform in grain, leaf and stalk for surface non- sterilized was higher than surface sterilized but it was less than 100 MPN 100 ml-1. Based on the results, in order to produce bioethanol without accumulation of heavy metals in the soil, it is suggested to plant sweet sorghum and irrigated with treated waste water.

Bio-stimulant of seaweed source as an organic alimentative to Bellary onion

Research Article of American Journal of Agricultural Research Bio-stimulant of seaweed source as an organic alimentative to Bellary onion: Bulb yield and Pyruvic acid levels Kosalaraman Karthikeyan, Munisamy Shanmugam Research and Development Division, AquAgri Processing Private Limited, B5, SIPCOT Industrial Estate, Manamadurai, Sivagangai District, Tamil Nadu, India. The influence of bio-stimulant Aquasap powder derived from the red seaweed Kappaphycus alvarezii was applied at 0.2% through foliar application on bellary onion at the establishment, vegetative, bulb formation and bulb development stage. Bulb yield and quality parameters such as total soluble solid, moisture content, ash content, organic content, pyruvic acid content, physiological loss and rotting percentage were studied. The crop yield in terms of bulb in treated plant was 31.65% over control with no statistical significant in the content of pyruvic between treated and control plants. Keywords: Kappaphycus alvarezii, Onion, Bio-stimulant, Pyruvic acid, Organic nutrient, Aquasap powder ...

Effect of storage condition on seed quality and health in jute O-9897

Research Article of American Journal of Agricultural Research Effect of storage condition on seed quality and health in jute O-9897 S. M. A. Haque1*, I. Hossain2 and M. A. R. Khokon2 1. Senior Scientific Officer, Plant Pathology Department, Pest Management Division, Bangladesh Jute Research Institute, Dhaka-1207, 2. Professor, Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh. The experiments were conducted in the laboratory of Plant Pathology Department, Bangladesh Jute Research Institute. The experiments were conducted during the period 15 January 2010 to 5 March 2012. Nine different types of containers viz. tin pot, plastic pot, poly bag, gunny bag, gunny bag lined with polythene, earthen pot, cloth bag, brown paper and IRRI poly bag, two level of moisture contents viz. farmers’ condition (13%) and recommended moisture condition (9.5%) by Bangladesh Gazette (2010) and seed treatment with Provax-200 and control (untreated) were used for the present study. Seeds were stored for 12 months and examined after 4. 8 and 12 months of storage. Among the nine containers, tin pot was found better in respect of moisture content, germination, mean germination time, vigour index and 1000- seed weight. Health condition of seeds was also superior compared to other containers. The poorest performance was observed in earthen pot regarding moisture content, germination, mean germination time, vigour index, 1000- seed weight and seed borne infection. The findings of the present study also reveal that recommended moisture content was better than farmers’ condition. Provax-200 treated seed also resulted better performance than non treated seed. So, Quality of jute seeds can be maintained by storage in tin pot with provax-200 treated and recommendation moisture content (9.5%). Keywords: Effect, storage container, seed quality and health ...
