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 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 Grain yield and weevil (Sitophilus zeamais Motsh.) resistant potential of 10 maize (Zea mays L.) varieties and their inter-varietal hybrids(The Genetics Society of Nigeria, 2019) Olufade, H.T; Musa, A.K; Bankole, F.A; Olaoye, G; Olakojo, S.AItem PERFORMANCE OF MAIZE INBRED LINES OF DIFFERENT MATURITY GROUPS UNDER DIFFERENT SOIL NITROGEN LEVELS(University of Abuja, Nigeria, 2023) Aboderin, O.S; Bankole, F.A; Oyekunle, M; Olaoye, G; Saminu, ZEvaluation of Per Se performance of inbred lines is crucial for assessing their inherent genetic potential and their prospective utility in population improvement and hybrid development. This study assessed 79 newly introduced maize inbred lines over two consecutive years (2018 and 2019) in Zaria, focusing on yield performance and low-nitrogen (N) tolerance under varying soil N conditions and N-fertilizer application rates. The results emphasized the substantial impact of nitrogen availability on various agronomic traits, including significant reductions in grain yield (35-95%), prolonged anthesis-silking intervals, and decreased plant and ear height, adversely affecting plant and ear morphology. Twelve screening indices were computed for each inbred line, revealing variations in the identification of tolerant lines, though some indices agreed on classifying certain lines as tolerant. The study identified 35 inbred lines as low-N tolerant, with consistent classification for SMLW5, SMLW156, and SMLW159 across multiple screening indices Line SMLW156 and SMLW5 recorded the highest yield under low-N, with a yield advantage of 71% and 48.5%, respectively, over the best check. The highest-yielding inbred lines under optimum-N conditions were SMLW156 and SMLW21, with yield advantages of 40% and 39.2%, respectively, over the best check. These identified lines hold promise as parents for population improvement and high-yielding low-N tolerant hybrids. Correlation results and Genotype x Trait Biplot analyses underscored the significance of ear aspect, stay-green characteristics, plant height, and ear height in achieving high grain yield under low-N conditions.Item Physical and Biochemical Attributes of Seeds for Screening Cowpea Genotypes for Resistance to Cowpea Weevil (Callosobruchus maculatus (f.))(Obafemi Awolowo University, Nigeria, 2022) Bankole, F.A; Musa, A.K; Olaoye, G; Takim, F.O; Olajide, O.OCowpea weevil {Callosobruchus maculatus (F.)} is an important field-to-store pest responsible for post-harvest loss of cowpea {Vigna unguiculata (L.) Walp.} seeds. One of the most economical and environment-friendly ways of preventing losses from the beetle is through the use of resistant cowpea genotypes. Physical and biochemical attributes of seeds play a key role in conferring resistance to the pest. Therefore, seeds of twenty-three cowpea genotypes were assessed for resistance to weevil infestation, nutritional and anti-nutritional factors. Relationship between the resistance parameters and the biochemical components of the seeds were also examined with the use of correlation analyses. Results showed that variability existed among the cowpea genotypes for seed physical resistance parameters such as initial seed weight, residual seed weight, seed weight loss, number of damaged seeds and weight of undamaged seeds. Association of reproductive efficiency with carbohydrate content, crude fibre and moisture content in the cowpea was positive and significant (r = 0.43*, 0.45* and 0.73**) while its relationship with protein content was negative and significant (r=-0.46*). The ash content correlated negatively and significantly (r=-0.46*) with the median developmental period. Cowpea genotype IT08K-125-107 exhibited the highest degree of tolerance to C. maculatus infestation, having suffered neither weight loss nor damaged seed and also had very low reproductive efficiency of the C. maculatus. The study concluded that while biochemical components played very little role in conferring resistance to C. maculatus in cowpea, increased carbohydrate content, crude fibre as well as reduced ash and protein content in the cowpea seeds decreased the reproductive efficiency and intensity of the C. maculatus infestation.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.
