Sexual behaviour of in-school adolescents in Ibadan, South-West Nigeria

This study was a crossectional survey conducted among 716 senior secondary school adolescents in Ibadan from March to August 2005. The result of 695 that was analyzed revealed that the mean age of 15±2.6years. 28.3% of the respondents had previous sexual exposure with higher proportions being male (p=0.00043). Majorities\' first sexual exposure was unplanned. Family settings and educational level do not have significant influence on the previous sexual exposure. The methods of sexual activity were mainly through vagina route while some had also practiced oral and anal sex. Most of those that are sexually exposed had more than one partner. About half of the respondents learn about sex from their friends while others through their parents and media. We conclude that in-school adolescents practiced unsafe sexual activity and they are therefore predisposed to STI/HIV and other reproductive health risks.

Effect Of Npk Fertilizer On Fruit Yield And Yield Components Of Pumpkin ( Cucurbita Pepo Linn.)

Pumpkin ( Cucurbita pepo Linn.) is a vegetable crop often grown without fertilizer by peasant farmers in Nigeria. With the increased pressure on land resources for other competing uses, farmers have adopted the use of fertilizers to boost crop productivity. This study was carried out for the purpose of evaluating the influence of NPK fertilizer on fruit yield and fruit yield parameters of pumpkin. The experiment was carried out under open field conditions in 2010 for two seasons at the Teaching and Research Farm, Obafemi Awolowo University, Ile-Ife, Nigeria. The farm is located on latitude 07°28’N and longitude 04°33’E about 244-m above sea level. NPK 15:15:15 compound fertilizer was applied as ring/side dressing at the rates of (0, 50, 100, 150, 200, 250 kg/ha). The experiment was a randomized complete block design and was replicated six times. Each plot size was 10 m X 12 m and consisted of 7 rows. Alley was 3 m, while the plants were spaced 2 m x 2 m. Data were taken on yield and yield parameters such as: fruit height, fruit circumference, fruit fresh weight, fruit dry matter, fruit yield, seed number and seed weight. The fresh fruit yield was 21 t/ha and 7t//ha for early and late seasons, respectively. Fruits number/ha significantly (p=0.05) increased from 7000 in control to over 10,000/ha at fertilizer rates between 100 and 250 kg NPK/ha. Fruit weight also increased from 9 to 17t/ha between control and higher fertilizer rates. Seed yield from the application at 100 to 250 kg/ha were similar and significantly better than control and 50 kg/ha NPK application. Mean seed yield between 100-250 kg NPK was 460 kg/ha. The value was 37% higher than at 50 kg NPK and 57% higher than in control. Increasing fertilizer above 100 kg NPK/ha did not significantly (p=0.05) increase the fruit yield nor the seed yield

Fruit Setting Under Controlled Natural Cross Pollination In Three Populations Of Coconut (Cocos nucifera L.)

Four coconut (Cocos nucifera L.) varieties, West African Tall (WAT), Malayan Green Dwarf (MGD), Malayan Yellow Dwarf (MYD) and Malayan Red Dwarf (MRD), planted in the Main Station of the Nigerian Institute for Oil Palm Research (NIFOR) near Benin City, in an isolated seed garden to produce different types of hybrids through open pollination were used Selected dwarf mother palms were emasculated, while the tall mother palms were not, allowing the tall palms to cross pollinate the emasculated dwarf palms. Controlled natural pollination of these selected dwarf mother palms was carried out for four years, 1996 – 2000. Data collected include number of bunches (NOB), number of buttons (NOBT) and number of nuts (NON). The various cross combinations (populations) studied were MGD x WAT (population 1), MYD x WAT (population 2) and MRD x WAT (population 3). Mean squares from the analysis of variance were significant (P< 0.01) for both palms and years for NOB, NOBT, NON and fruit setting percentage. The significant palms effect indicates that genetic variability existed among the palms, while the significant years mean squares suggested that climatic factors and other factors common to all environments, encounted for a proportion of the variation in the environment. The fruit setting percentage for the four years of investigation was 51.4% with a range between 48.2 – 54.3%. There was no significant difference in fruit setting percentage between the three populations. Maximum setting percentage was 54.3% in population 3, 51.7% in population 1 and 48.2% in population 2.
