Mixed Fruit Production Using Fuse Locally Soured Citrus Fruits Orange(Citrus Silences)

Mixed Fruit Production Using Fuse Locally Soured Citrus Fruits Orange (Citrus Silences) Tangerine Citrus Reticulate) Lemon C Groups (Citrus Paradox)

Literature Review

The citrus species are small trees and shrubs of about 3.5 meters in height with simple dark green and glossy leaves which have a joint between the leaf and the petiole. The trees are covered with leaves all year round and are replaced after the bloom by the fruits flowers  are abundant mostly white and fragrant bloom  occurs  between February and April and the period between it. Harvest varies for 8 –17months depending on fruit variety and climate condition. Citrus are subtropical and are rich in vitamin C parthocularly in the pithy white layer or albeds found under the peel citrus fruit have a farfel in taste because of their high water content and the presence of citrus acid and sucrose. The relative amount of these two determines whether the fruit is sharp or sweet to the taste. Orange and grape fruit make up most of the citrus while others are produced in good quantity in floods the gulf state, califomia and Arizoma are the main growing areas.

Characterizing Some Selected Abakaliki Rice Genetically Using Rapd.

Genetic Characterization of Abakaliki Rice Using Random Amplified Polymorphic DNA Maker (RAPD)

Introduction

Rice is a cereal given containing high content of carbohydrate (i.e. it is an energy given food). It is a staple food that is commonly consumed in half of the world population. Rice is a nutritional crop contain one-fourth of the calories consumed by humans (Smith and Bruce D, 1998). Rice plant belongs to the grass family whose seeds are used as food when boiled and it is also used for beer production in brewery companies (used as adjuncts). Rice monocotyledon is grown as an annual crop but can also survive as a perennial crop to produce food (Huang et al., 2012). Rice cultivation is favored by countries and areas of high rainfall but it can be cultivated anywhere. Genetic evidence has shown that rice originates from a single domestication 1, 200-13,500 years ago (Molina et al., 2011) in the region of ancient China at the pearl region of ancient rice was spread to southeast and South Asia through East Asia and the Western Asia spread rice to the Europe and was later introduced to American through European colonialism.

Zooplankton And Fish Composition In Ehoma Lake,Afikpo, Ebonyi State

 

Zooplankton And Fish Composition In Ehoma Lake,Afikpo, Ebonyi State

Introduction

Lakes are constantly changing as a result of variation in the physical, chemical, biological and human activity processes. By observing zooplankton community changes, lakes manager have an indication of possible changes happening in the lake ecosystem(brown 1981).lakes are convenient system for studies in community ecology because they are well bounded and replicated across the landscapes(Forbes 1587). The lake, as a result is considered the defacto observational unit for community analysis (Brown 1974). The changes in zooplankton community of a lake transcedes from large Daphnia copepod to mostly small Bosmina and Rotifers; There may have been a change in the predation pressure by fish. Other lake condition influence zooplankton community and size structure such as Cladocerans,Daphnia and Bosmia which require calcium for their carapace. Changes in calcium availability in the water column can affect the Cladoceran community (Tessier and Horwitz 1990).According to the size efficiency hypothesis,larger cladocerans can filter algae from the water column more efficiently than smaller zooplankton(Hulsmann et al 2005).

Phytoplankton, Macrobenthos and Fish Composition of Ehoma Lake, Afikpo

Phytoplankton, Macrobenthos and Fish Composition of Ehoma Lake, Afikpo

Abstract

A study on the phytoplankton, macrobenthos and fish composition of Ehoma Lake, Afikpo was conducted weekly between January and February 2014 using selected stations. The distance of the three (3) stations was 100m apart from each other. The physicochemical parameters tested are Dissolved oxygen (DO), Temperature, pH, Transparency, Conductivity and Depth. The result obtained envisaged that the Lake was within the acceptable level for productive water. The result obtained was subjected to statistical analysis using Completely Randomized Design (CRD). All the stations showed insignificant difference (P>0.05) for all the parameters tested. A total twenty-three (23) species of phytoplankton belonging to four (4) families were identified.

Effect of Housefly Maggot Meal on Gonadal Development in African Catfish

Effect of Housefly Maggot Meal on Gonadal Development in African Catfish (Heterobranchus Longifilis) Brood Stock

Introduction

Effect of Housefly Maggot:Escalating cost of conventional proteinous feedstuff for fish production has immensely contributed to the low level of animal protein intake in Nigeria (FAO 2000). Qualitative feed production is considered to be one of the major factors affecting the success of fish production in aquaculture (Otubusin and Ifili 2000). Fishmeal is one of the most essential feed ingredients in fish feed, due to its high percentage of crude protein and rich essential amino acid (Pauly et al., [Read more…]

Soil Physico-Chemical Properties Along A Toposequence In The Rolling Hill

Soil Physico-Chemical Properties Along A Toposequence In The Rolling Hill Of Ekoli – Edda  In Afikpo South L.G.A. Of Ebonyi State, South-East Nigeria.

 A major factor limiting agricultural development in Nigeria is the lack of information on soil and land characteristics. Soil topography plays a major role as one of the factors that influence pedogenesis and in the process that dictates the distribution and use of soils on the landscape (Hoosebeek et al. 2000, Esu et al. 2008). Toposequence and catena concepts have emanated as slope-soil evolutionary processes.

Landscape position influences rainfall, drainage and erosion. Water velocity on a slope affect deposition of materials in suspension, the largest size particles, like sand, are the first to drop of suspension, fine clay size particles can be carried further away from the base of the slope before they are deposited (Glassman et al. 1980). Hill slope orientation also affects the microclimate of a place, inclined surface facing into the sun tend to be warmer and drier than flatter surface facing away from the sun. [Read more…]
