Effects of Sowing Date on Yield and Yield Parameters of Some Groundnut (Arachis hypogaea L.) Cultivar Under Rainfed Condition in Ogbomoso, Nigeria

The study examined the variation in number of flowers, number of nodules, number of pods and seed yield of some groundnut cultivar as affected by planting date in Ogbomoso, Oyo state, Nigeria under rainfed condition. This is necessary to determine when moisture availability will be at optimum starting from the onset of rainfall, to avert loss which could arise from improper timing of planting. Teaching and Research Farm of Ladoke Akintola University of Technology Ogbomoso with average annual rainfall of 1000 mm and temperature ranging from 28 to 33 ºC was used for the experiment. A 4 by 4 factorial experiment with four varieties of groundnut (three improved varieties Samnut-10, Samnut-23, Samnut-22 and Kampala (local variety)) and four planting dates of a week interval (29th April, 6th May, 13th May and 20th May, 2016) were tried without chemical amendment. All the parameters evaluated were affected by the planting date.  Samnut-23 and Samnut-10 planted on 29th April produced the highest mean number of flowers (15.67) and number of nodules (116.00) respectively which were significantly higher than others. Cultivar type did not have significant influence (p≤0.05) on the growth parameters. However, number of pods and seed yield was influenced by the cultivar. The highest number of pods (103.00) from this study was produced by Samnut-23 planted on 29th April. It was observed that the high number of pods produced by Samnut-23 did not translate to seed yield because Kampala produced the highest seed yield (73.51 g/plot) which was significantly higher than yield from other cultivars tried. Groundnut cultivars responded differently to planting date tried, with best planting period being early month of May. It was observed that all the cultivars produced their least seed yield when planted towards the end of month of May, therefore, should be discouraged for the tried cultivars at the trial location.

Mn(II), Co(II), Ni(II), and Cu(II) complexes of amino acid derived Schiff base ligand: Synthesis, characterization and in-vitro antibacterial investigations

Four complexes of Mn(II), Co(II), Ni(II) and Cu(II) with Schiff base ligand (H3L) derived from 2-amino-3-methylbutanoic acid and acetylacetonate were synthesized. All complexes were characterized by elemental analysis, Fourier-transform infrared spectroscopy and electronic spectroscopy. The results confirmed the coordination of the ligand to metals in tridentate fashion via the hydroxyl oxygen, the azomethine nitrogen and the enolic acetylacetonate oxygen. Antimicrobial activities were established for all complexes, free ligand and ciprofloxacin for comparison. Both the ligand and its metal complexes were active against Gram-positive and negative bacterial strains. The Cu(II) complex, showed highest antibacterial activity among the complexes screened. Other complexes displayed considerable antibacterial activity. Octahedral geometry was proposed for the metal(II) complexes with the Schiff base.                     KEY WORDS: Schiff base, Amino acid, Metal Complexes, Antibacterial agents   Bull. Chem. Soc.

Assessing the challenges impeding effective primary health care delivery in Southwest Nigeria

This study seeks to investigate the challenges impeding healthcare delivery in selected Primary Health Care facilities in South West Nigeria. A quantitative approach was adopted with purposive sampling of 241 health workers across PHC facilities in South West Nigeria. Data was analysed using the Statistical Package for Social Science (SPSS version 22). The study revealed seven main challenges which included shortage of manpower, inadequate medical equipment, lack of employee motivation, lack of basic infrastructure, unavailability of drugs, poor funding and cultural belief. Consequent upon these findings, government interventions such as employment of more skilled personnel, improved working conditions, employee motivation, provision of basic facilities/equipment and better financing, is required to enhance the quality of service and sustainability of PHC in Nigeri

Environmental Effects of Processing Marine Clay in Olotu, Ondo State, Nigeria

In this work, analysis of the released gas from calcined marine clay and lime shell was investigated. Study of the emitted gas/air from the calcined clay and shell showed that average concentration of carbon dioxide (CO2: 20.09PPM and 8.12PPM) are below the maximum standard natural concentration 600PPM of carbon dioxide in fresh air and the recommended World Health Organization Threshold Limit Value (TLV) of 500PPM. Average carbon monoxide (CO) concentration (0.004PPM, 0.010PPM) and sulfur dioxide (SO2) concentration (0.002PPM are below the Nigeria Ambient Air Quality Standards (NAAQS) and World Health Organization (WHO) maximum limit of 10PPM-20PPM (for carbon monoxide) and 0.01PPM- 0.5PPM (for sulfur dioxide) for an 8-hourly time. It was established that the average concentration of C0, C02, and S02 is so low and so pose no threat to the environment based on the review of the existing regulation, standards and codes (WHO and NAAQSO).

ANALYSIS OF MULTIMEDIA CHANNELS OF INFORMATION AVAILABLE TO FISH FARMERS IN OGUN STATE, NIGERIA

Fish farmers in Nigeria lack adequate information and their production capacity is low. The study ana- lyzed the multimedia channels of information available to fish farmers in Ogun State, Nigeria. Multi- stage sampling techniques was used to select 120 fish farmers in the study area. Primary data were obtained with interview schedule. Descriptive statistics were used to analyze the data collected. Most of the farmers (97.5%) were male and married. Many (43.3%) had primary education while 30.9% had no formal education. Majority (76.1%) had radio sets while 45.3% and 28.3% had television and phone respectively. Farmers’ accessibility to information was high in radio (79.2%) and extension agents (73.3%) but low in television, flyers, trainings, phone, internet and fellow farmers. Most of the farmers (85.0%) preferred extension agents, radio (71.6%) and television (68.3%) as their source of information on fish farming. Majority (80.0%) preferred Yoruba as the language of broadcast and pub- lications, 16.7% preferred English while 3.3% preferred Igbo. Most (83.3%) of the farmers regarded lack of electricity as the foremost constraint to their access to information on media. Other constraints identified were non-relevance of information to farmers’ felt needs (73.3%), feedback problem (60.0%), inadequate fund (40.8%) and illiteracy (23.3%). Chi-square analysis showed a significant association 2 at p ≤ 0.05 between farmers’ choice of information channels and age (π=19.60), educational level 2 2 2 2 (π=39.82), years of farming (π = 20.48), income (π = 34.03), and media related constraints (π = 6.92). The study established that age, educational level, years of farming, annual income and con- straints experienced by the farmers played significant roles in their choice and use of information channels, and that, farmers have more access to extension agents as channel of information. It was recommended that more information on fish farming should be provided through the multimedia and be based on farmers’ felt needs. More extension workers should be employed and trained while phone-in radio and television programmes should be regularly aired and viewing centres and radio groups established in strategic locations

Influence of Different Fertilizer Types on the Growth and Yield of Two Varieties Cucumber (Cucumis melo)

The growth, yield and nutritional quality of Poinsett and Marketmore varieties of cucumber in response to compost and NPK fertilizer application were evaluated at the Teaching and Research Farm of the Ladoke Akintola University of Technology, Ogbomoso, Oyo State, Nigeria. The six fertilizer combinations are T1 (0 kg N), T2 (100% NPK, 600 kg NPK 15:15:15), T3 (100% Tithonia compost (TC), 5 tons/ha), T4 (75% NPK + 25% TC), T5 (50% NPK + 50% TC) and T6 (25% NPK+ 75% TC). The treatments were arranged as 6 × 2 factorial scheme in Randomised Complete Block Design with three replicates. Data were collected on growth parameters, fruit yield, calcium content and iron content. Data collected were subjected to analysis of variance and difference among treatments means was computed using Least Significant Difference at 0.05 probability level. The results revealed that at the point of maximum growth Poinsett cucumber variety produced significant longer vine (173.78cm); higher number of leaves (23.56) and more robust stem girth (3.01 cm) than the other variety. At 8 weeks after sowing (WAS) the longest vine length (216.67cm) and number of leaves (29.33) were obtained from cucumber plants treated with 5 tons/ha. Varietal effect was not significant (p≤0.05) on cucumber fruit yield and firmness. The vine length, fruit girth, stem girth, number of leaves were significantly influenced by the application of 5 tons/ha. At 8 WAS, the longest vine 216.67cm and highest number of leaves (27.33) were recorded from 5 tons/ha, while the widest stem girth (2.10cm) was gotten from 50% NPK + 50% TC treated cucumber. Fruit yield was significantly improved by the application of different combination of fertilizer. Plant that received fertilizer had significant better fruit yield compared with non-fertilized one. However, the use of 50% NPK + 50% TC gave the highest fruit yield. The study concluded that combine application of 300 kg NPK + 2.5 ton/ha TC would be sufficient for production of the two varieties tried in this study.
