    ASSESSMENT OF THE COMPOSITION OF SOLID WASTE IN SELECTED SITES OF GWAGWALADA AREA COUNCIL, ABUJA FCT NIGERIA
    (Department of Biological Sciences, Nasarawa State University, Keffi, 2011-05-10) Joshua, Alanana Abu ; Shittu, G.A.
    An assessment of the amount and composition of solid waste generated in four selected sites of Gwagwalada was conducted in October, 2004 and March, 2005. Various types of waste generated were sampled randomly and analyzed. Biodegradable waste accounted for 93.20% of total waste generated during the harvesting season and 92.12% of total waste generated during the harvesting season and 91.12% in planting season. Of the biodegradable waste, 13303.47g was generated in dry season (harvesting) while 13286.99g in wet season (planting). T-test analyzing revealed that significant differences existed both between the type and amount of waste generated in harvesting (dry) season and planting (wet) season (t=03668;P<0.05). From the above findings, it is cleared that more waste was generated during the harvest season than in planting season

    DORMANCY AND GERMINATION OF SEEDS OF TERMINALIA CATTAPA (INDIAN ALMOND) FROM GWAGWALADA AREA COUNCIL, FCT, ABUJA.
    (Department of Biological Sciences Plant Science and Biotechnology Unit Nasarawa State University, Keffi, Nigeria, 2009-02-13) A, Isma'ila.; Joshua, Alanana Abu
    Investigations were made on the dormancy and germination of seeds vt Vcrminalia cattappa, a widely cultivated tree species in the tropics and commonly grow in the savannah ofNign ia. These Investigations were carried out in the laboratory and in the nursery garden. Methods of terminating seed dormancy and standard nursery practices were adopted. Two seed types have been found to occur in the pods based on the colour of the test and these were conveniently designated as dark brown (DBS) and light brown seeds (LBS). Using some of the well known methods of terminating dormancy i.e. dry and wet heat treatments, mechanical scarification and chemical scarification. Both seeds types were found to have dormancy problems. Dormancy in Terminalia cattappa was terminated by dry and wet heat treatment at 10(fCfor two minutes. Mechanical scarification by abrasion with gravel or coarse river sand and chemical scarification by soaking in 0.4% KMnOr The results showed that the dormancy in both seed types (DBS and LBS) were seed-coat imposed. The percentage germination records before and after treatment of dormancy was 0.35% and 60% - 70% germination capacity after chemical scarification and5% after mechanical scarification.

    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi, 2016-10-08) Joshua, Alanana Abu; Iyokpa, A.M.; Yakubu, D.S.
    Effects of NPK, cow dung, and poultry on the growth and yield of fluted pumpkin (Telfairia occidentalis Hook f) was conducted at the research farm, Botanical Garden of the Department of Biological Sciences, Nasarawa State University, Keffi. This experiment consists of three treatments and one control. The NPK, Cow dung, poultry manure were arranged in a Randomized Complete Block Design (RCBD) and three levels of replicates. So that we have a total of twelve (12) in the experiment. It was observed in this research that the vine length was significantly increased with application of poultry manure to the soil, but application of NPK fertilizer increase the number of branches significantly at the 10WAP, also application of poultry manure increase the numbers of leaves significantly when compare to NPK fertilizer application. It was observed that at the 12WAP, there was a significant difference in the leaf diameter due to the application of poultry manure. The experiment showed that the application of poultry manure significantly increases the leaf length, leaf diameter and vine length throughout the research. The use of poultry manure in the cultivation of fluted pumpkin in Keffi Nasarawa state is recommended.

    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 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.

    GENETIC VARIABILITY IN MINERAL COMPOSITION AMONG DIFFERENT STRESS TOLERANT MAIZE (Zee mays L.) GENOTYPES IN KEFFI, NASARAWA STATE
    (Department of Plant Science and Biotechnology, Nasarawa State University Keffi, 2020-01-14) Anadi, A.C.; Onovo, J.C.; Joshua, Alanana Abu ; Idris, A.
    Genetic variability m mineral composition among different stress tolerant maize genotypes was carried out. Thirteen genotypes and two local checks (control) were evaluated in randomized complete block design (RCBD) with three replications. The twelve agronomic characters studied were plant height, ear per plant, anthesissilking interval, days to pollen, days to silking, days to maturity, number of cob per plant, leave length, Zinc, Magnesium, and grain yield. The result obtained from the analysis of variance for all the agronomic traits studied showed significant differences among all the genotypes at (P < 0.01). The highest mean value for zinc was seen in SAM 15 (3.39 mg/kg), followed by SAM 24 (3.26 mg/kg) and L2 (control) (3.16 mg/kg). The least mean value for zinc was found in SAM 37 (2.25 mg/kg). The highest mean values for magnesium was found in LI (control) (6.53 mg/kg), followed by SAM 38 (6.48 mg/kg) and SAM 15 and L2 (control) (6.45 mg/k0). The least mean value was found in SAM 46 and SAM 37 (5.98 mg/kg). The mean performance for Iroi. :!'owed there was significant difference between the genotypes. SAM 48 had the highest mean value (8.35 mg/kg; for iron, followed by SAM 26 (4.05 mg/kg) and SAM 46 (3.83 mg/kg). SAM 24 had the least mean value (2.09 mg/kg). Correlation studies revealed Magnesium to be positive and significantly correlated zinc (r = 0.52). Number of cub per plant was positively correlated to ear per plant (r = 1.00) while ear per plant was significant and negatively correlated to zinc (r = - 0.381) and magnesium (r = -0.341). The results from this research have shown that high genetic variability exist with regards to mineral composition and this warrant effective selection for further improvement. The results from the broad sense heritability estimates for the 12 characters studied showed that all the characters are heritable with values range from 69.11 for leaf length to 100.00 for zinc, magnesium and iron. The information presented in this research should be of value to nutritionists. This paper thus recommend that SAM 48 be giving to children because of its iron content.
