Comparative Assessement of Organic and Inorganic Fertilizers on the Performance of African Egg Plant (Solanum Macrocarpon) in Ekiti State, Nigeria
Studies were carried out to assess the influence of organic and inorganic fertilizers on the performance of Solanum macrocarpon L. (African egg plant) in Ado Ekiti, Ekiti State Nigeria. Organic fertilizers (Poultry manure and cow dung) were applied at the rate of 150g per pot and the inorganic (NPK 20:15:15 and Urea) at 6g per pot to make a field equivalent of 8t ha¬-1 and 200kg ha-1 respectively. Poultry manure gave the best performance in terms of height, number of leaves, leaf area, shoot biomass, relative growth rate and fruit weight. The relative growth rate, number of leaves and plant height were similar in NPK and Urea applied pots but lower than those of poultry manure. The results obtain from this study indicated that poultry manure could be an alternative source of fertilizer to S. macrocarpon production in place of the inorganic NPK and Urea fertilizers. The study further suggests that poultry manure used for crop improvement is a means of turning waste to wealth in crop production. The leaves and fruits produced from poultry manure fertilized soil supports the current global campaigns for organic food production.

Constraints and Extent of Access to Productive Resources and Agricultural Services among Women Farmers in Awka and Aguata Agricultural Zones of Anambra State, Nigeria
The study investigated constraints and extent of access to productive resources and agricultural services among women farmers in Anambra State, Nigeria. Specifically, it identified income generating activities of women farmers in the state, identified the productive resources and agricultural services available to them and determined the extent of availability of the resources and services and constraints to accessing the resources. Purposive random sampling technique was used to select a total of 120 women farmers. Data were collected with aid of a structured questionnaire. Data were analyzed using mean, percentages and frequencies. Results showed that majority (60%) of the respondents are married and a majority (50%) has formal education. It was further revealed that the respondents had diversified income generating activities with a majority engaging in processing of agricultural products (98.3%) and farming (95.8%). The results also showed that majority of the respondents indicated labour as the most available productive resource in the area. On the extent of access to productive resources, the result revealed that labour (x=3.0) and processing facilities (x = 2.50) are the accessible productive resources. Finally, the result revealed sharing of knowledge (x = 2.56) and marketing facilities (x = 2.98) as the only agricultural services accessible to the farmers. Constraints encountered lack of capital, poor electricity connection, lack of access roads, poor radio signals, illiteracy among others. It was recommended that the existing land ownership policies in the country should be reviewed to promote ownership by women farmers and extension education/visit be improved as well.

Effect of Depot-medroxyprogesterone acetate on the kidney of rat: A Histological Study
Endogenous natural progestins are essential for the initiation and maintenance of pregnancy but exogenous progestins and their derivatives may induce adverse effect on different organ. The kidney beinga vital and highly active organ is affected by most of the drugs. It’s the main organ responsible for excretion of the metabolic products of hormones. Therefore the present study aimed to evaluate the effect of injectable contraceptive, Depot-medroxyprogesterone acetate on the kidney of white albino rat. There was significant increase in the diameter of PCT, DCT, renal corpuscle, glomerulos, and Bowman’s space of experimental rat kidney. Hemorrhage was seen in cortical and medullary region with lymphocytic infiltration in Bowman’s space and necrosis of some renal corpuscles. The study concluded that the more the duration and dose of the DMPA severe the alternation in the histological architecture of kidney. Keywords:DMPA, PCT, DCT, Bowman’s space, hemorrhage. Introduction A contraceptive method is one which helps the women to avoid unwanted pregnancy resulting from coitus and there are many method of contraception but the ideal is one, which is safe effective, acceptable, reliable, and requires less medical supervision.1Several characteristics of injectable contraceptives have led to their widespread use as they provide a highly effective contraception that last for more than 2 month after a single dose of injection and they do not contain estrogen so, they are free from adverse effect of estrogen.2The only injectable contraceptive drugs currently available are Depot-medroxyprogesterone acetate and norethisterone enantate.3 Depot-medroxyprogesterone acetate (DMPA) is an aqueous suspension of medroxyprogesterone acetate (MPA), a synthetic analog of 17?-hydroxyprogesterone and variant of the human hormone progesterone.4This is also classified as sex hormone binding globulin(SHBG).5Depo -Provera, a microcrystalline suspension of medroxyprogesterone acetate (DMPA), is a long-acting, highly effective injectable contraceptive and one of the major means of family planning.6 The primary mechanism of action is the inhibition of gonadotropins hormone (FSH and LH) thus inhibition of ovulation.7 It alsoincreases the viscosity of cervical mucus, making the mucus less easily penetrable to sperm.8 The contraceptive mode is a depot injection containing 150 mg medroxyprogesterone acetate which is administered by intramuscular route at a plasma concentration of about 1ng/ml) given in the gluteal or deltoid muscle within first 5th day of menstruation.9 DMPA has been favored because it creates amenorrhea and reduces cycling in many patients while simultaneously serving as highly effective contraception which protects against the development of uterine fibroids.10 It has been used as a contraceptive agent by more than 68 million women in more than 114 countries worldwide.11 Unlike oral contraceptives, DMPA have been proven to be relatively safe and is free from the adverse effect of estrogen and furthermore, progestogens, unlike estrogens, do not suppress lactation, which is an important consideration for postpartum contraception where infant health is dependent upon breast-feeding.12 Evidence suggests that progestogen-only injectables are more cost-effective than the combined oral contraceptive (COC) pill even after 1 year of use.13 Endogenous natural progestins are essential for the initiation and maintenance of pregnancy but exogenous progestins
