ABSTRACT

An experiment was carried out at College of Agriculture, Science and Technology, Lafia, Research and Teaching farm in 2019 to ‘investigate the effects of combined treatment of ash+nodumax and Fertiplus 3-2-7 fertilizer on physiological growth and yield of Soybean. Routine analysis was carried out on the field in both cropping seasons using standard analytical procedures. The field was manually cleared and demarcated into plots measuring 2.5m x 2.5 m. Four ridges of 2.5 m long and a spacing of 0.75 m were constructed per plot with a 1m inter plot boundary. Three fertilizer sources; Nodumax+ash (combined), and Fertiplus 3-2-7 that served as treatments, were properly applied based on specifications. There were plots without fertilizer application that served as control. Treatments were replicated two times and laid out in a Randomized Complete Block Design. Soybean seeds of the variety TGX-1935-3f, TGX-1951-3f, and TGX-1904-6f were drilled into the ridges. The crop was grown to maturity within the season and harvested after twelve weeks. Data collected was subjected to the analysis of variance (ANOVA) using gens tat 12.1 edition. Significant difference among means was observed, and Fischer’s least significant difference was used to separate means. Results from this study showed that there was response to treatment application during the period of plant growth.The result showed that the highest records of all parameters were observed in combined treatment of nodumax+ash, which gave the best yield in terms of grain weight, while Fertiplus 3-2-7 treatment gave the best result in terms of vegetative growth.The result was thus concluded in this order: Combined ash+nodumax treatment >;fertiplus 3-2-7 treatment.

Keywords: Fertiplus 3-2-7, Ash, Nodumax,

ABSTRACT

The need to understand black hole formation, property and absorption of other celestial bodies is an interesting issue in Astrophysics and Astronomy. In this short article we avoided complex mathematical difficulty to obtain Schwarzschild’s radius of some planetary bodies, and this radius was computed using Newtonian expression for escape velocity. Results obtained shows that among the planets Jupiter requires a very large amount of gravitational pull to reduce to black hole and was found to be exactly the same with that using Schwarzschild’s metric.

Keywords and phrases: Black hole, Schwarzschild’s radius, Newtonian expression, escape velocity

ABSTRACT

Phytoremediation involves the use of living green plants for in situ risk reduction and or removal of contaminants from contaminated soil. The objective of this study therefore was to evaluate the effectiveness of African spinach (Amaranthus hybridus) in extraction of chromium (Cr) from contaminated soil. The research consisted of the following treatments: 0, 38, 76, 114, 156, 190 (Cr mg/kg). Potassium dichromate was used as the source of chromium. The plant data collected were leaf count, plant height, stem diameter, shoot weight, the root weight and chromium concentration in shoot and roots which were analyzed using analysis of variance and the Fisher’s pairwise comparisons. The result showed that there was no significant effect of treatments on growth parameters. However, there was significance difference in chromium concentration in the shoots of Amaranthus hybridus among the various treatments when compared to the control. Mean maximum extraction of chromium were within the range 58.0 to 63.0 mg/kg. This indicates that Amaranthus hybridus possess great potential in phyto-extraction of chromium and other heavy metals from contaminated soil.

ABSTRACT

The incorporation of culture into developmental policies and projects of rural- urban dwellers is apt at this period in our history as this offers various advantages. Culture is the be all and end all of development (Senghor, 2001) and as such the successful design of a Proposed Delta state cultural centre will satisfy the quest to achieve development. Design strategies that encourage community participation needs to be meticulously explored and employed; a deviation from this will result into a failed approach at taping into the wealth of benefits culture provides. This journal therefore seeks to highlight architectural ways of resolving the issue of ventilation and lighting by adhering to natural principles that will give functional and enhanced design actualization. This study uses analytical approach of research into past innovations; its successes and failures and by extension propose workable solutions.

Keywords: Culture, Development, Strategies, Design, Participation.

ABSTRACT

This paper has investigated the effects of insincere and deceptive promises by politicians on citizens’ voting decision. It starts with a discourse on the promises usually made by politicians during electioneering campaign, the objective of such promises and the deceptiveness inherent in the promises. An empirical study was carried out whose main objectives are: to determine the purpose of making election promises; whether politicians make insincere and deceptive promises or not; if politicians and their parties keep their campaign promises once elected; and the impact that deceptive political promises have on the electorate. Field survey was conducted within four Nigerian cities, Abeokuta, Ago-Iwoye, Ibadan, and Ikeja. Cluster sampling technique was adopted in selecting distinct clusters- campuses, offices, households, and markets, from the population. In all, 300 people were selected for the research while a structured questionnaire was used for data collection. The empirical study confirms the assertion that some promises made by politicians are bogus and/or mostly exaggerated, and insincerely made, with the main purpose of deceiving the electorate to vote for them. The study also shows that women are more influenced by insincere and deceptive political promises than men in their voting decisions. Also, less educated people are more influenced by deceptive political promises than the more educated people. The paper therefore recommends among others that: the public should hold politicians accountable for their promises and appropriate Federal and State laws should be promulgated to make this recommendation effective; politicians should make sincere, realistic, and feasible promises in their election campaign. The paper also recommends that we should make fulfilment of freely-made election promises legally binding on our politicians.

Keywords:  Deception, insincerity, politician, promise, voting decision.
