Effect of Computer-Aided Instruction on Chemistry Students’ Achievement in Organic Chemical Nomenclature in Enugu Education Zone of Enugu State, Nigeria (Published)
This study investigated the effect of Computer-Aided Instruction on chemistry students’ achievement in organic chemical nomenclature in Enugu Education zone of Enugu State, Nigeria. One research question and one hypothesis guided the study. The design of the study adopted was quasi experimental, pretest-post test, non equivalent control design. The sample for the study comprised of 308 chemistry students (122 male and 186 female) purposively sampled from a population of 2,734 SS1chemistry students in Enugu Education zone of Enugu state. The instrument used for data collection was Teacher Made Organic Nomenclature Achievement Test (TMONAT) with 20 items multiple choice test. The instrument was constructed by the researchers and validated by two experts, one from the department of science education and one from the department of mathematics computer education (measurement and evaluation unit, Enugu State University of Science and Technology, (ESUT). TMONAT achieved a reliability of 0.87 calculated using kuder Richardson 20 (KR-20). Treatment lasted for six weeks. Mean and standard deviation were used to answer research questions while hypothesis was tested at 0.05 significance using Analysis of Covariance (ANCOVA). Males and Females were taught using computer-aided instruction (CAI). The findings of the study revealed that male and female chemistry students taught organic chemical nomenclature (OCN) with Computer-Aided Instruction (CAI) were almost at par in their achievement in OCN. Gender has no significance influence on students’ achievement in OCN with CAI. Based on the findings, it was recommended among others that Curriculum planners should include CAI as a model of instruction that promotes gender-equity.

Effect of Organic (Cow Dung Slurry) and Inorganic (N: P: K 15:15:15) Fertilizer on the Growth and Yield of Tomato (Lycopersicon Lycopersicum) in Anyigba, Kogi State, Nigeria (Published)
A pot experiment was conducted in April 2018 in faculty of Agriculture, Kogi state university, Anyigba. The experiment was laid in a completely randomized design (CRD) with five treatments in four replications and results obtained were subjected to analysis using ANOVA and means were separated at 5% level of probability using Fisher Least Significant Difference Test. The treatment consisted of a control (T0), 2 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T1), 4 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T2), 6 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T3), 8 tonnes/ha of cow dung slurry + 50 kg/ha of NPK 15:15:15 fertilizer (T4).Data were collected on plant height, number of leaves, stem girth, number of branches, number of fruit per plant, and fruit diameter respectively. It was observed that the organic and inorganic manure used increased the soil physical-chemical properties as well as the performance parameters of the test crop (Tomato). Recommendation was made at the rate of 6t/ha of cow dung slurry +50kg of NPK 15:15:15 (T4) for optimum yield and performance of tomato.

Business Development Strategy of Organic Vegetables in Agribusiness Development Station (Ads) IPB (Published)
Agribusiness Development Station (ADS) IPB is one of the agribusiness companies that rely on organic vegetables one of their main traded commodities. ADS IPB has been a high daily demand, but limited production area causing low production capacity and weak farmer partnership system make the company unable to reach market demand. This study aims is identify the performance has been running to develop the ADS organic vegetable business, analyze the internal and external factors that affect the development of organic vegetables business in ADS, formulating to improve it is development using descriptive method, Internal Factor Evaluation (IFE), External Factor Evaluation (EFE), SWOT Matrix and Architecture Strategy. The SWOT Matrix results is 12 alternative strategies chosen as ADS IPB to develop organic vegetable business strategy. Based on architecture strategic results, the sequence of strategies for the next five years starting from provide farmer partner distribution facilities to ADS IPB up to marketing and selling online.

Organic Black Tiger Shrimp Farming System (Iso 65 Ifoam): Strategy Through Open Spirit Reap Back To Nature (Published)
The strategy is very logical considering cultured shrimp is for export, not to meet the domestic market demand. . The object studied is the traditional shrimp farmers and organic shrimp farmers.The purpose of research is to find a strategy of foreign exchange earned through the implementation of organic shrimp farming systems (ISO 65 IFOAM). The study used a descriptive approach. To find a strategy using SWOT analysis of foreign exchange earned by weighting the Balanced Score Card. While the effects of the implementation of shrimp farming organic systems analysis with Snow Ball Effect Matrix Balanced Score Card. The results showed that through the implementation strategy organic shrimp farming systems following priority actions are: strengthening the bargaining power in the international market through the supply of organic shrimp exports were stable throughout the year, improving the quality of the supply of organic shrimp.

Growth and Fruit Yield of Tomato As Influenced by Combined Use of Organic and Inorganic Fertilizer in Kabba, Nigeria (Published)
Field experiments were conducted to investigate the effects of integrated use of chemical and organic fertilizers on growth and fruit yield of tomato in Kabba College of Agriculture. The experiment involved five treatments which are as follows: 125kh/ha NPK+3t/ha poultry manure, 125kg/ha NPK+3t/ha cow dung, 125kg/ha NPK+3t/ha kitchen waste, 125kg/ha NPK 15:15:15 and Control. The treatments were laid out in a Randomized Complete Block Design (RCBD) and replicated four times. The parameters taken on soil chemical properties are soil pH, total nitrogen, available phosphorus and soil organic matter. Growth and yield parameters taken are as follows: plant height (cm), number of leaves, and stem girth (cm), number of fruit per plant, fruit length (cm), fruit diameter (cm) and yield per land area (kg/ha). Result obtained from parameters studied (Plant height, leaf numbers, branch number, stem girth, fruit number per plant and fruits weight) revealed that tomato performed better (P<0.05) with the application of 125kg/ha NPK+3t/ha poultry manure application. The also, study showed that use of inorganic and organic fertilizer had better effects on growth and yield of tomato. Therefore, for good yield and better productivity of tomato, a combination of 125kg/ha NPK fertilizer + 3t/ha poultry waste is recommended for tomato production in the study area.

FACTORS INFLUENCING THE APLICATION OF ORGANIC VEGETABLE FARMING IN SAMARINDA CITY (CASE STUDY AT NORTH SAMARINDA SUBDISTRICT, EAST KALIMANTAN) (Published)
The objectives of research are to understand the application rate of organic vegetable farming and to analyze factors influencing the application of organic vegetable farming in Samarinda City. Research is carried out in North Samarinda Subdistrict, Samarinda City, from April to June of 2013. Method of research is survey and the sampling technique is simple random sampling. Result of research has shown that (1) the application of organic vegetable farming in Samarinda City is classified into four categories, which include conventional category for very low application rate, knowing-organic category for low application rate, interest-in-organic category for moderate application rate, and toward-organic category for high application rate; (2) some factors such as age, land width, number of training, farmers’ general knowledge about organic, farmers’ knowledge about the principle and benefit of application, and farmers’ knowledge about organic agriculture technique, will give significant influence on the application of organic vegetable farming; and (3) the application rate of organic farming has significant influence on the production and income of vegetable farmers. Farmers with toward-organic application rate of vegetable farming have higher production and income than those with conventional, knowing-organic and interest-in-organic farming.
