    EVALUATION FOR DIVERSITY IN GROWTH AND YIELD OF TOMATO (SOLANUM LYCOPERSICUM L.) GERMPLASM
    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi, 2023-03-12) Musa, U.H.; Isa, H.; Joshua, Alanana Abu; Dasikwo, S.Y.
    The tomato {Solarium lycopersicum L.) fruit is quite popular and consumed in a variety of dishes across the globe. Despite the popularity, there is scarcity of information regarding characters that distinguishes varieties and often difficult to identity the germplasm with the best set of phenotypic characters from fruits available in the local market. In this study, five tomato germplasm, namely Roma Savannah, Tima, UTC, Dan Zaria and Tagino were collected from the Nasarawa State College of Agriculture, Lafia were evaluated at morphological levels in a Randomized Complete Block Design (RCBD) with five replications at the Plant Science and Biotechnology Research Garden, Nasarawa State University, Keffi. The mean performance of five tomato varieties studied yield (fruits) and other agronomic traits were significantly different (P >0.05). The average results clarified that the Dan Zaria lines recorded the highest flowering values, as well as some fruit and vegetative growth traits. Furthermore, Tima, Tagino and UTC had the minimum number of fruits/plants, number of leaves, sub branches and flowers. In conclusion, the application for morphological techniques could be considered to provide suitable parameters for studying the evolution of the genetic divergence between the studied tomato lines.

    EVALUATION FOR YIELD OF SOME SELECTED GROUNDNUT (Arachis hypogaea L.) CULTIVARS GROWN AT KEFFI, NASARA WA STATE NIGERIA
    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi, 2020-02-14) Dasikwo, S.Y.; Joshua, Alanana Abu; Abdullahi, M.H.; Ombugadu, N.A.
    Evaluation for yield of selected groundnut cultivars was earned out; nine cullivars were evaluated in a Randomized Complete Block Design (RCBD) with three replication at the Department of Plant Science and Biotechnology Research/ Experimental Garden Nasarawa State University Keffi. Plant nutrient analysis were significantly different (P^TO.05), Ca (3.35-5.05%), P (0.41-0.49%), N (4.00-4.54%) and K (3.62-5.58%). Fresh mass per plant, dry mass per plant, number of pods per plants, number of seed per plants, pod formation per plants without seeds, 100 seed weight, fresh yield mass and dry yield mass was studied for yield determination were significantly different (P.T0.05). Two genotypes, ICGV 15-5891 and ICGV 15-07947, displayed a significantly high number of seeds produced per pod. ICGV 15-07999 produced fewer seeds per pod compared to all other genotypes. ICGV 15- 5891 was the least performing genotype when compared to ICGV- 15-09932 with respect to dry matter and pods produced. ICGV-12991 produces significantly higher seed yield of 936kg ha-1. Genotype ICGV-12991 has a moderate dry matter and high number of pod per plant at harvest which makes it high yielding for the location to which they were evaluated. Therefore, ICGV-12991 is highly recommended for farmers as well as useful for breeding programme.

    EVALUATION OF THE PHENOTYPIC CHARACTERIZATION OF PHYSICS NUTS {Jatropha curcas L.) SEEDS MORPHOLOGY IN SOME SELECTED LOCATIONS OF KEFFI LOCAL GOVERNMENT AREA, NASARAWA STATE
    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi, 2017-06-04) Joshua, Alanana Abu; Kwon-Ndung, E.H.; Dasikwo, S.Y.
    Jatropha curcas L. is a multipurpose shrub that has acquired significant economic importance for its seed oil which can be converted to biodiesel, as an alternative to petrol-diesel. This study was carried out on the phenotypic characterization of the seed morphology of Jatropha curcas from eight locations of Keffi Local Government area for providing support for the breeding and allocation of seeds. Five morphological traits were investigated which include: seed weight, seed length, width lateral diameter and seed length and width ratio. The results revealed that the seed morphology had significant variation at 1% and 5% of levels of significance among the locations of the different populations of Jatropha curcas with high level of phenotypic diversity and therefore provenance selection has great potentiality.

    PROXIMATE COMPOSITION FOR PROTEIN AND OIL CONTENTS OF SOME SELECTED GROUNDNUT (.Arachis hypogaea L.) CULTIVARS GROWN AT KEFFI, NASARAWA STATE NIGERIA
    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi, 2020-02-11) Dasikwo, S.Y.; Joshua, Alanana Abu; Abdullahi, M.H.; Ombugadu, N.A.
    The proximate composition for protein and oil contents of some selected groundnut cultivars showed that among all the genotypes evaluated, only ICGV-15-07947 has the highest oil content of 46.26% while others ranges from 35.03 - 39.02% . ICGV-15-07947 has the highest protein content of 29.42% than other cultivars. ICGV-15-09932 has 26.74%, ICGV-15-5891(26.47%), ICGV-15-09992(25.77%), ICGV-15-07999 and ICGV-12991 (25.23%), ICGV-15-09994(24.89%), ICGV-15-86024(24.36%) and the lowest with the protein content is ICGV-15- 07803(24.02%) showing significant difference (p<0.05) between them. Cultivar ICGV-15-07947 has the highest protein contents and oil contents therefore its highly recommended because that makes it good for human consumption, usefulas animal feeds as well it could be used in soap making and when product which requires high protein content are to be developed it will be useful.
