Item Assessment of Relationship Between Cane Yield and Component Traits in Sugarcane Accessions(Genetics Society of Nigeria., 2021) TAKIM, F.O; Bankole, F.A; Olakojo, O.O; Olaoye, GItem Economic assessment of tillage methods and integrated weed management for maize production in a Northern Guinea savanna of Nigeria.(Faculty of Agriculture, Bayaro University Kano, Nigeria., 2020) Michael, G.C; TAKIM, F.O; Olaniyi, O.W; Tijani-Eniola, H H.Item EFFECT OF PERIOD OF SUGARCANE CULTIVATION ON THE ABUNDANCE AND DISTRIBUTION OF WEED SEEDS IN THE SOIL PROFILE1(Pakistan sugar journal, 2014-10) ADERETI, R.O.; TAKIM, F.O; ABAYOMI, Y.AThe study was established on three sugarcane growing fields with known cropping history, located in the southern Guinea savanna ecological zone (Latitude 90 29' N and Longitude 40 35' E) of Nigeria during the 2012/2013 and 2014 growing seasons to determine the relationship between weed seedling emergence and soil properties. Soil seedbank was sampled from sugarcane fields to a depth of 0-10cm, 11-20cm, 21-30cm and was estimated using the direct seedling germination method, and the emerged weed seedlings were monitored over a period of 8 months concurrently with a floristic survey conducted on same fields. Data collected on weed seedling emergence were transformed and subjected to analysis of variance, regression and correlation analyses. The results of the study demonstrated that soil properties exert significant influence on the occurrence and distribution of specific weed species in the sugarcane cultivated fields and there was a strong positive correlation (r=0.86, p≤0.003) between seedling emergence in the seedbank and field emergence. Paspalum scrobiculatum, dominant weed species, correlated positively with soil particle sizes and all the chemical properties except Na, K and acidity. This implies that predictable estimate of the sugarcane fields’ weed flora can be made from the soil seedbank and soil properties, with such information; it would be possible to schedule a more appropriate weed management strategyItem Effect of Time of Vine Harvesting on Re-growth and Root Yield of Three Sweet potato (Ipomoea batatas L. Lam.) Varieties(Crop Science Society of Nigeria, 2019) Abimbola, O.O; Olaoye, G; TAKIM, F.O; Afuape, S.O; Alfonso, O.C; Salawu, L.AItem Effect of Weed Removal and Plant Population on Weed Suppression and Performance of Maize (Zea mays L.) in the Southern Guinea Savanna of Nigeria(Library and Publications Committee, University of Ilorin, Ilorin, Nigeria., 2013) Omisore, J.K; TAKIM, F.OItem Effect of Wildfire on Weed Floristic Composition and Soil Status in a Teak (Tectonia grandis L.) Plantation at Ilorin, Nigeria(Faculty of Agriculture, Taraba State University, Jalingo, Nigeria, 2019) TAKIM, F.O; Affinnih, K.O; Falola-Olasunkanmi, J.A; Garuba, I.A; Osatuyi, O.OTeak is widely planted for timber in the tropics, grown in botanical gardens as an ornamental for its large leaves and spreading flower clusters. The study was conducted on a Teak Plantation established in phases between 2008 and 2012 to examine the impact of wildfire on weed seedling emergence and soil nutrients at Ilorin within the southern Guinea savanna of Nigeria. Soil samples were collected within three depths (0-10 cm, 11-20 cm and 21-30 cm) few days after the plantation was burnt by uncontrolled wildfire in 2016 and 2017. The weed seeds present were enumerated and soil properties analysed. Floristic weed survey was conducted on the teak plantation between May and November of each year. Results showed that Andropogon gayanus (18%), Tephrosia pedicellata (17%) and Senna obtusifolia (11%) were the most abundant weed species. Wildfire significantly (p<0.05) influenced weeds emergence. Twenty–five weed species were identified during the floristic weed survey. Twenty-two (22) % and 14 % of the identified weed species emerged on the burnt and unburnt field, respectively. Silt decreases while sand and clay fractions increased in the burn fields. Total N, organic C and available P increased in alternate years and depth of soil sampling. This result is valuable in aiding the prediction of likely weed infestations in a wildfire affected field, provide a valuable input in determining weed control strategy and soil nutrient managementItem Fruit yield and Juice Quality attributes of six exotic tomato introductions under different cropping systems in the southern Guinea savanna of Nigeria(Crop Science Society of Nigeria, 2014-10-01) Olaoye, G; TAKIM, F.O; Bankole, FItem Genotype by Environment Interaction of Early and Intermediate Maturing Maize Varieties in the Southern Guinea Savanna of Nigeria(Crop Science Society of Nigeria, 2017-10-01) Gbadamosi, A; Olaoye, G; Akinwale, R.A; Bankole, F.A; TAKIM, F.OItem Impact of Plant Density, Fertilizer Rate and Weed Control on Grain Yield of Maize (Zea mays L.).(Faculty of Agriculture, Federal University of Oye-Ekiti, 2017-01-01) TAKIM, F.O; Philips, E.O; Olayiwola, O.IField experiments were established to evaluate the effects of fertilizer (NPK) rates, contrasting plant densities and weed control on weed infestation and yields of maize in the Southern Guinea savannah of Nigeria. The first trial (trial I) was laid as a split-split-plot in three replications using three maize varieties (LNTP-Y, BR9928DMRSR-Y and PVA8-Y), three plant densities: 53,333 plants ha-1 (a row on a ridge with 1 plant/stand at 75x25cm), 106,666 plants ha-1 (a row on a ridge with two plants/stand at 75x25cm) and 106,666 plants ha-1 (2 rows on a ridge with plant/stand at 75x25cm) and three NPK 20:10:10 rates (100:50:50, 150:75:75 and 200:100:100). Two best interactions between plant density and fertilizer rate were selected from trial I and laid as main plots in a split-plot design where six weed control methods were the sub-plots in trial II. The results showed that high fertilizer dose and low densely populated maize increased weed seedling population and biomass production. Maize plant density significantly influenced grain yield of maize, seeding at 106,000 plants/ha (2seeds/hill at single row/ridge) with application of NPK at 150:75:75 gave 6.33 tonnes/ha of BR 9928DRM SRY, 6.67 tonnes/ha of LNTP-Y C2 and 6.47 tonnes/ha of PVA8. Pre-application of Primextra Gold(R) at 2.5kg ai/ha and post-application of Guardforce(R) at 1.25kg ai/ha gave significantly higher grain yield, 4.89 tonnes/ha. It can be concluded in this study that seeding maize at two seeds per hill (106,666 plants/ha) with the applications of NPK fertilizer at 150:75:75, pre-Primextra Gold(R) at 2.5kg ai/ha and post Guardforce(R) at 1.25kg ai/ha will lead to 100% increase in maize grain yieldItem Influence of Seeding Pattern on Weed Cover and Yield of Soybean [Glycine max (L.) Merr] in a Southern Guinea Savannah of Nigeria.(Weed Science Society of Nigeria, 2021) Osatuyi, O.O; TAKIM, F.OItem Pattern of field emergence of weeds in an arable field in the southern Guinea savanna ecology of Nigeria(Weed Science Society of Nigeria, 2013-11-04) TAKIM, F.O; Fadayomi, O.Item Performance of Tomato Varieties as Affected by Difference Plant Density(Horticultural Society of Nigeria, 2019) Modupeola, T.O; TAKIM, F.O; Olaoye, G; Akintoye, H.AThe management practice, which greatly influences tomato fruit yield, is plant density. Field trial was carried out to determine the suitable plant densities that would give optimum tomato yield. The trial was laid in a randomize complete block design (RCBD) in a split plot arrangement and replicated three times. Tomato varieties were the main plots (Roma VF and Ibadan local) and plant density (17,777, 26,666 and 53,333 plants/ha-1) was the sub plots. Data collected included plant growth parameters and yield component. All data were analyzed using the analysis of variance (ANOVA) and significant means were separated by the least significant difference at 5% probability level (LSD0.05). Ibadan local with the density of 53,333 plants/ha-1 gave the highest yield. Significant differences among the two varieties for a number of factors confirmed their different genetic background. The growth and yield attribute were affected by the two treatments; variety and plant density. In conclusion, Ibadan local and Roma VF with the density of 53,333 plants/ha-1 gave the highest yield.Item Qualitative and Quantitative Performance of Selected Exotic Sugarcane (Saccharum Officinarum L.) Varieties in Nigerian Southern Ecologies.(Faculty of Agriculture, University of Abuja, Nigeria, 2022) TAKIM, F.O; Olaoye, G; Kawuyo, M.G; Bankole, F.ANigeria currently relies on the importation of over 95% of her sugar requirement due to a combination of factors which include low installed capacity of the existing sugar companies, inefficient factory operation as well as the dependent on the use of old and low yielding sugarcane varieties. One of the ways to ameliorate this situation is the use of high yielding and adapted sugarcane varieties. To this end, 28 of the sugarcane varieties were evaluated for four cropping cycles (2013 - 2017) at two sites in Nigeria. The trials were laid out as a randomized complete block design with four replicates. Each plot was 6 ridges of 10 m long and 1.4 m between the rows. Three-eyed cane setts of 6-7 months old which were disease free were 2 laid horizontally end-to-end. Data were collected from a net plot (60 m ) on brix, yield and yield components and data were analysed. Identification of the top yielding varieties from each site based on selection criterion (cane yield + acceptable brix, rank summation index (∑RSI) values for combination of cane yield and brix as well as ∑RSI value for Kg-brix and cane quality parameters). Results showed significant (p≤0.05) differences among the varieties for cane yield cane brix %, pol %, purity and expected sugar recovery for the selected varieties. Three varieties were identified: B80689, Co9906 and CoC671 with mean yield of 77.99, 61.26 and 59.93 t/ha, respectively. The identified varieties had acceptable cane brix ≥20 %, pol % of 18.00, purity of 90% and expected sugar recovery of 10.00 and above. These varieties exhibited good quality traits and their genetic potential. There are therefore recommended to for adoption by the sugarcane estates for cultivation in southern ecologies of Nigeria.Item Survey of Sedge Weeds for Root–Knot Nematode in Arable Fields in a Southern Guinea Savannah of Nigeria(Weed Science Society of Nigeria, 2021-11-04) Garuba, I.A; Falola-Olasunkanmi, J.A; Affinnih, K.O; TAKIM, F.O
