Mode Of Application

The effect of zinc (Zn), boron (B) and sulphur (S) on the yield and quality of groundnut in a field experiment with three levels of Zn (0, 5, 10 kg Zn ha<sup>−1</sup> as Zn-EDTA as basal), two levels of B (0 and 0.25% boric acid as foliar spray) and three levels of S (0, 25, 50 kg S ha<sup>−1</sup>as CaSO<sub>4</sub>.2H<sub>2</sub>O) in a factorial RBD were studied. Basal application of Zn @ 5 and 10 kg ha<sup><sup></sup>1</sup> caused an increase in nut yield by 3.7% and 28.3% respectively over control, whereas, application of S @ 25 and 50 kg ha<sup>−1</sup> increased the nut yield by 38.3% and 56.6% respectively over control. Conjoint application of Zn @ 10 kg ha<sup>−1</sup> and S @ 50 kg ha<sup>−1</sup> caused an increase in nut yield up to 73.4% over the control. Results, therefore, revealed that conjoint effect of S and Zn towards nut yield was more effective than that of B application. Application of Zn, S and B significantly increased their nutrient uptake in nuts. On an average, S, Zn and B uptake by groundnut ranged from 11.4 to 21.0 kg ha<sup>−1</sup>, 0.14 to 0.40 kg ha<sup>−1</sup> and 0.12 to 0.25 kg ha<sup>−1</sup>, respectively. Integrated mode of application of Zn, B and S showed a positive interaction as yield increase with their uptake in groundnut. Oil content in nuts ranged from 45.3 to 54.4%, while iodine value ranged from 97.8 to 90.5%. Application of S and Zn significantly increased the oil content, while it significantly decreased the iodine value in groundnut. So, application of micronutrients <italic>viz</italic>. Zn and B as well as S fertilization could be a useful strategy not only to increase the yield but also the quality of groundnut.

The objectives of this study were to establish the impact order of the oil-palm kernel processing variables, namely: kernel moisture content (KMC), kernel heating temperature (KHT), kernel heating duration (KHD), and kernel particle size (KPS) on the palm kernel oil (PKO) yield; to develop an empirical model for the PKO yield as influenced by the KMC, KHT and KHD; to investigate the effect of the KMC, KHT and KHD on the PKO quality; and to specify levels of the kernel variables for the maximum PKO yield with minimum variability. The study was undertaken using oil-palm kernels of unidentified variety from Nsukka, Nigeria. The statistical analysis of data was performed with Design-Expert 8P and Minitab 19 Software at P = 0.05.  The impact order of the studied kernel variables on the PKO yield, using an expeller (MS-100), was found to be the KPS, KMC, KHD, and KHT. For the maximum PKO yield with minimum variability in the PKO yield, a KMC of 5% (wb), a KHT of 80 °C, a KHD of 10 min, and a KPS of 11 mm and above is recommended.

The main purpose of this research was to observer effect co-solvent type (n-Hexane, chloroform and without co-solvent)  toward yield and quality of biodiesel via in situ transesterification process using microwave irradiation. The process was studied at microwave power 450 watt, reaction time 4 minutes, methanol to seed ratio 25:1 and catalyst concentration 5%. The physicochemical parameters of the biodiesel produced such as viscosity, density and acid value were analysed and compared with the SNI 7182-2012 standard. The experimental result showed the maximum yield biodiesel 78,32% obtained by using co-solvent chloroform.Test result of physicochemical properties (viscosity, density and acid value) of biodiesel products using co solvent n-Hexane, chloroform and without co solvent showed that these products conform to the SNI 7182-2012 standars. The type of co-solvent only affectedon biodiesel yield dan not affected on biodiesel quality (viscosity, density and acid value).  ABSTRAKTujuan penelitian ini adalah untuk mempelajari pengaruh jenis co-solvent (n-Hexane, chloroform dan tanpa co-solvent) terhadap rendemen dan mutu biodiesel secara trasesterifikasi in situ menggunakan radiasi gelombang mikro.
