Several growth parameters, including Shoot fresh weight, number of leaves at various weeks after planting, and plant height, were measured to assess development.

Field capacity and water use efficiency significantly increase Shoot fresh weight, while the aeration methods show marginal effects.

The study aims to determine water use efficiency, as well as the effect of water stress on the yield of pepper under drip irrigation system. The study was conducted at the Agricultural and Bio-environmental Engineering Research Farm of the Federal Polytechnic Ilaro, Ogun State, Nigeria. Four irrigation treatments were investigated. The experiment had four irrigation levels. The first irrigation application treatment (A) consists of 100% of actual crop evapotranspiration (ET). The second (B) was 75% ET. The third (C) was 50% ET and fourth (D) consist of 25% ET. The experiment was arranged in a randomized complete block design (RCBD) with four replications and 2 varieties of pepper: Capsicum annum and Capsicum frutescens. Irrigation applications were applied for 3 weeks after transplanting and thereafter continued for the whole growing season. Parameters such as such soil, agronomic and crop’s consumption water use were measured and the results subjected to statistical analysis. The results indicated that there was a significant difference between the WUE, yields and growth parameters under different levels of irrigation in the two pepper varieties. The results showed that water use efficiency, yields and other agronomic parameters such as plant height, number of leaves and fruit length and weight were higher during the studies periods for both pepper varieties under treatments A and B compared with other treatments C and D respectively. However, there was no significant difference in WUE of treatments A and B. Statistical analysis among the agronomic parameters showed a significant difference (p<0.05) in all the treatments. It was concluded that irrigating at 75% ET in the study area will result in water saving and maximum sustainable production of these pepper varieties.

Relying on previous studies and constructs of the two-step hypothesis/opinion leadership theory, it was assumed that voters in rural areas had poor access to the mass media. In addition, they obtained information about presidential candidates and their programmes through opinion leaders who might have greater access to the mass media.

The results revealed that KNN, SVM-RBF, DT, RF, MLP, and the combined model had: accuracy score of 62.99 %, 91.57 %, 52.45 %, 89.93 %, 33.02 % and 49.41 % respectively; the Matthews correlation coefficient (MCC) gave 50.84 %, 88.85 %, 34.76 %, 86.61 %, 6.12 % and 29.95 % respectively; F1 score also gave 59.92 %, 91.24 %, 44.83 %, 89.58 %, 19.58 % and 43.59 % respectively. It can be seen from the results that combining models for machine learning operation does not necessarily give higher performances in all score category but the confidence in individual model to accurately learn on the dataset or from neighbor model on its own.

The study was conducted at the Agricultural and Bio-environmental Engineering Research Farm of the Federal Polytechnic Ilaro, Ogun State, Nigeria. Four irrigation treatments were investigated. The experiment had four irrigation levels. The first irrigation application treatment (A) consists of 100% of actual crop evapotranspiration (ET). The second (B) was 75% ET. The third (C) was 50% ET and fourth (D) consist of 25% ET. The experiment was arranged in a randomized complete block design (RCBD) with four replications and 2 varieties of pepper: Capsicum annum and Capsicum frutescens. Irrigation applications were applied for 3 weeks after transplanting and thereafter continued for the whole growing season. Parameters such as such soil, agronomic and crop’s consumption water use were measured and the results subjected to statistical analysis. The results indicated that there was a significant difference between the WUE, yields and growth parameters under different levels of irrigation in the two pepper varieties. The results showed that water use efficiency, yields and other agronomic parameters such as plant height, number of leaves and fruit length and weight were higher during the studies periods for both pepper varieties under treatments A and B compared with other treatments C and D respectively. However, there was no significant difference in WUE of treatments A and B. Statistical analysis among the agronomic parameters showed a significant difference (p<0.05) in all the treatments. It was concluded that irrigating at 75% ET in the study area will result in water saving and maximum sustainable production of these pepper varieties.

It was concluded that Peer influence has both negative and positive impact on adult’s behavior. Among major recommendation was that Individuals should be encouraged not to give into peer pressure in order for them to be accepted and fit in a group Keywords: Peer Pressure, Middle Adulthood, Independent Decision Organization, Management |

The lateritic soil used in this study was taken from the sedimentary formation located at Abalabi ( 53’ 13.758”N, 7’ 59.994”E), Ajegunle, along Papalanto-Ilaro road, Ogun State, Nigeria and palm kernel shell wastes were taken from oil palm producing plant at Iweke along Ilaro-Owode Road, Ilaro, Ogun State, Nigeria. The palm kernel shells were broken into pieces passing through 5mm sieve and then substituted for lateritic soil in the range of 0% to 50% at 5% intervals with 0% palm kernel shell substitution serving as control experiment. In line with BS 1377 (1990), pressure loads were applied on the composite materials and California Bearing-Ratio tests conducted at different test water contents for all the substitutions. From the results, California Bearing-Ratio value increased gradually as palm kernel shell substitution increases while 25% palm kernel shell substitution has the maximum CBR value at both top and bottom. In addition, for the 40% to 50% palm kernel shell substitutions, maximum CBR values were observed from their initial test water content. The composite material with palm kernel shell at 25% can be used for road base and sub base.

These factors could be examined through the fusion of quantitative and qualitative tradition with a view to helping voters make up their choice of presidential candidates during elections. This study investigates how voters in rural areas of Nigeria sought information about presidential candidates in the 2019 presidential elections. Relying on previous studies and constructs of the two-step hypothesis/opinion leadership theory, it was assumed that voters in rural areas had poor access to the mass media. In addition, they obtained information about presidential candidates and their programmes through opinion leaders who might have greater access to the mass media. The study also identified factors influencing voters on their choice of presidential candidate. Information was obtained from a sample size of one thousand voters and were randomly stratified based on the six geo-political zones of the country. In addition to this, one Focus Group Discussion was held in each of the six zones to enhance the validity and reliability of data obtained. Among other findings, the study revealed that residents of rural and sub-urban areas are gaining more access to the mass media (radio, TV and social media) and are more likely to vote the presidential candidate of the party they are affiliated with, irrespective of the personal qualities of the candidate.

In this study, lateritic soil and plastic were taken from Ilaro, Ogun State, Nigeria. The plastic wastes were grounded into pellets and substituted with laterite. The tests were conducted in line with BS 1377 (1990) to determine the moisture content and compaction. The results were compared with the simulated results of Olarewaju (2013) in the study of the response of underground structures due to blast loads. In the said work, soil and pipes were modeled; loads from accidental explosions were estimated using Unified Facilities Criteria (2008). Various constituents of blast considered are ground media, pipes, intervening medium, blast, blast characteristics and method of analysis (finite element formulation and solution using ABAQUS/Explicit in ABAQUS). From the results, the lowest dry density value is 0.96kg/m3 and 1.130 kg/m3 respectively at 30% plastic pellets mixed with lateritic soil. In the work of Olarewaju (2013), dimensionless deflection at the crown, invert and spring-line of underground pipes in loose material is low compared to dense material. It is clear that at 30% and above plastic substitution, the density is relatively low and this could as soft backfill material reduce the impact of accidental explosions on underground structures.
