EFFICACY OF USING FUNGUS (Aspergillus niger) AS AN ANTAGONIST AND SYNTHETIC NEMATICIDE (FURADAN) IN THE MANAGEMENT OF Meloidogyne incognita in OKRA

 

           

The experiment was carried out to investigate the effects of Aspergillus niger and synthetic nematicide (furadan) in the control of Meloidogyne incognita population in okra. The experiment was located at Afugiri in Umuahia North Local Government Area of Abia State, Nigeria. The pot experiment consisted of four treatments replicated five times each laid out in completely randomized design (CRD). Each pot received 2000 nematode eggs which served as inoculums. The treatments used included the following combinations: Fungi and Nematode; Furadan, Fungi and Nematode; Furadan alone, which served as control. Results obtained showed that number of galls, nematode eggs in roots and juveniles in soli were drastically reduced (P<0.05) compared to the number of nematode eggs inoculated which indicates the effectiveness of the treatments used. However, no significant difference was observed in plant height and number of leaves. Fungi and nematode treatment compared favorably with treatment furadan and nematode and can be harnessed as a measure to manage the problem of plant parasitic nematode in okra production.

ANALYSIS OF GOVERNMENT INITIATIVES ON RICE PRODUCTION IN NIGERIA

 

           

The study was carried out to review the Nigerian government initiatives or policies formulated and injected into the rice subsector over the years to encourage increased rice production and attainment of self-sufficiency. The databank of the national Bureau of Statistics and information from relevant departments in the Federal Ministry of Agriculture were utilised. The study appraised the performance of government initiatives or policies over the years in the rice subsector, established policy gaps and proffer complementary or alternative policy measures by which increased rice production and attainment of self-sufficiency can be achieved.

THE STUDIES ON DISTRIBUTION AND COMMUNITY STRUCTURE OF FIVE SELECTED SPECIES OF MARINE GASTROPODS ALONG THE ROCKY INTERTIDAL AREA OF VERAVAL, GUJARAT, INDIA

 

           

The present study deals with gastropod community structure along Veraval coast, Gujarat. Total five gastropod species were selected viz., Turbo intercostalis, Turbo coronatus, Cerithium morus, Cellana radiata and Chiton peregrines for present study from October 2012 to April 2013. The physio-chemical parameters viz., water temperature ranged between 23.22 to 25.83 ºC, water salinity between 34.75 to 35.67 ppt, pH 7.87 to 8.28 and dissolved oxygen ranged between 4.23 to 5.39 mg L-1. Cerithium morus and Turbo coronatus showed dominance along the study location. The species diversity (H’) values ranged between 0.99 to 1.21. The species richness (D) values ranged between 0.90 to 0.97 and species evenness (E) values having range between 0.62 to 0.75 bids / individuals.
