This study examined the economics of cocoa production in Irewole Local government Area, Osun State, Nigeria. 90 cocoa respondents were selected using a well-structured questionnaire while descriptive and inferential statistics used to analyze the data collected. The study showed that 39.99% of the respondents in the study area were within the age range of 41 and 50 years, while the mean age is 46 years. 78.89% of the respondents were male, while the remaining 21% were female. 78.89% of the respondents were married while 11.11% were divorced and 10% were widowed. 63.33% of the respondents were muslims, while 36.67% were Christians. 49% of the respondents were within the range 1-5 of family size. 57.77% of the respondents have a farming experience that is between the range of 10 and 20 years and 50% had their capital from cooperative. It also showed that 66.67% got their farmland by inheritance and 38.89% of the respondents had a major problem of lack of funds. It was also discovered that farm size, family size, level of experience, cost of labour and transportation cost were significant factors affecting the output of cocoa in study area, while sex, age, cost of land, cost of weeding were not significant in determining the output of cocoa production. The study suggests that government should come up with programs aimed at improving farm size, make credits available at little or no interest, provide basic amenities in the rural areas and development of locally made farm machineries at affordable prices to the farmers.
A comparative study on the effect of chemical fertilizers and bio-fertilizers was done on the quality of soil in Agricultural land. An experiment was conducted in randomized completely blocks design (RCBD) with four replicates. The treatment were (T1= Untreated, T2= Chemical Fertilizer, T3= Bio-Fertilizer at Agricultural land near Besa (Nagpur District), Maharashtra in 2016. The bio-fertilizer used in this study was Azoto barwar1 and chemical fertilizer was Urea (46% N). The results indicated that there were significant difference between the application bio-fertilizer and chemical fertilizer. All the physical and chemical parameters of soil indicates the significant difference after the application of chemical and bio-fertilizers. the study shows that the major nutrients are in higher concentration in case of bio-fertilized soil.
A simple, cheap and accurate method was developed and validated for the determination of trace Mercury (II) ion in real samples. Conditions such as temperature, contact time, concentration of reactant, pH were optimized. The method was based upon the reaction of Mercury (II) ions with the pit shells of sour cherry ( Prunus Cerasus Rock )(PCR) and after completing the adsorption the mixture was filtered and Mercury (II) ion concentration was determined in filtrate after adding KI, NH3 and KOH (Nessler’s reagent) by UV-visible the formed complex (K2HgI4) is pallid yellow but in presence ammonia is deep yellow shows an absorption maximum at λmax=355 nm in borate buffer of pH 5-10. Beer’s–Lambert law of the colored Hg–adsorbent complex was obeyed in the concentration range of 0.05–20µgmL−1Mercury (II) ions, with a relative standard deviation in the range of 1±0.28%. The limits of detection (LOD) and quantification (LOQ) of the procedure were 0.010 and 0.030µgmL−1 Hg2+, respectively. The proposed method was applied for the analysis of mercury (II) in aqueous solution samples. The validation of the method was experimented by comparison with the data obtained by the inductively coupled plasma-mass spectrometry (ICP-MS). The statistical remedies of data in terms of Student’s t-tests and variance ratio f-tests have revealed no importance differences.
The present study was aimed to explore the preliminary phytochemical constituents of Sargassum linearifolium (Turner) J.Ag. from Koothankuzhi coast, Tirunelveli district, the south east coast of Tamil Nadu, India. The preliminary phytochemical analysis was conducted in three extracts namely methanol, chloroform and benzene by Harborne method. The preliminary phytochemical analysis showed the presence of anthocyain, alkaloids, cardiac glycosides, coumarins, flavonoids, phenols, phlobatannins, quinones, saponins, steroid, tannins and terpenoids. alkaloids, phenols, steroid, tannins and terpenoids showed the maximum presence, being found in three different extracts and anthocyain, cardiac glycosides, coumarins, flavonoids, phlobatannins, quinones and saponins in two extracts. From the results, it was concluded that the extracts of Sargassum linearifolium (Turner) J.Ag. was found to be the presence of a number of active secondary metabolites. This report will lead to the isolation and characterization of these active secondary metabolites for bioefficacy and bioactivity.
A low grade siliceous ferruginous fine grained rock phosphate analysing18.07% P2O5, 46.31% SiO2, 23.93%CaO, 1.70%MgO, 1.61%Al2O3, 7.74% Fe2O3, 1.03% F, 0.09% Cl, 0.09% C and 2.85%LOI was subjected to a process comprising of wet high intensity high gradient magnetic separation( WHIHGMS) at D80 50 microns followed by differential soap flotation (DSF) of non magnetic fraction employing 1.5 kg/t of Sodium silicate, 1.5 kg/t of caustic starch and 1.2 kg/t of Sodium oleate ( saponified oleic acid) followed by 2 cleanings. Either DSF or WHIHGMS at essential very fine MOG of D80 50 microns could not produce SSP grade concentrate due to dilution by SiO2, Fe2O3 and Al2O3. A process comprising of wet high intensity high gradient magnetic separation( WHIHGMS) at D80 50 microns followed by differential soap flotation (DSF) of non magnetic fraction employing 1.5 kg/t of Sodium silicate, 1.5 kg/t of caustic starch and 1.2 kg/t of Sodium oleate ( saponified oleic acid) followed by 2 cleanings, produced a concentrate assaying 33.53% P2O5, 9.68% SiO2, 46.93%CaO, 1.40%MgO, 1.45%Al2O3, 1.96% Fe2O3, 1.85%LOI at70% P2O5 Dist., at 39 wt. % yield meeting the SSP specifications. Detailed tests are recommended.
