Macho F1) to Combined Application of Organic and Inorganic Fertilizers 2021-05-11T15:27:58+08:00 Enrique Biñas, Jr. ulycagasan@vsu.edu.ph Ulysses A. Cagasan ulycagasan@vsu.edu.ph <p>Fertilizer application does not only influence the growth and yield of sweetcorn but also its physicochemical and sensory attributes. This study was conducted to determine the effects of the combined application of organic and inorganic fertilizers on the total soluble solids (TSS), titratable acidity (TA), pH and sugar contents of freshly harvested sweetcorn, and on the sensory qualities of newly cooked and five (5) day stored sweetcorn. The treatments were designated as follows: T<sub>0-</sub> Control (without fertilizer applied), T<sub>1 </sub>- Inorganic fertilizer at 90-60-60 kg ha<sup>-1</sup> N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O, T<sub>2</sub>- 5,000 kg ha<sup>-1</sup> of vermicompost + 45-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O, T<sub>3</sub>- 5,000 kg ha<sup>-1</sup> of poultry manure + 45-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O, T<sub>4</sub>- 5,000 kg ha<sup>-1</sup> of cow manure + 45-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O, T<sub>5</sub>- 5, 000 kg ha<sup>-1</sup> of goat manure + 45-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O, T<sub>6 –</sub> 5,000 kg ha<sup>-1</sup> of mudpress + 45-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O, T<sub>7 -</sub> Foliar spray (Fermented Golden Snail applied five times at 150ml/16liters of water) + 45-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>O<sub>5</sub>, K<sub>2</sub>O<sub>. </sub>These were laid out in RCBD with three replications. Results showed that the highest pH values and sugar contents were detected from plants applied with 5,000 kg ha<sup>-1</sup> regardless of organic fertilizer and half of the recommended rate of inorganic fertilizers. Likewise, sweetcorn stored for five days in an ambient condition maintains its color, taste, aroma, and texture when applied with organic and inorganic fertilizer regardless of the sources of organic materials.&nbsp; It is advisable not to dehusk the sweetcorn during harvest to preserve its marketing potential, especially when it is to be stored. Likewise, only the sweetness/taste of sweetcorn was reduced after five days of storage but still acceptable by the consumers` preference.&nbsp; These results suggested that fertilizer, either pure inorganic or in combination with organic, can significantly increase the yield and also influence its sweetness.</p> 2021-01-01T00:00:00+08:00 Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/162 PERFORMANCE OF PROMISING PEANUT (Arachis hypogaea L.) GENOTYPES GROWN IN DRY AND WET SEASON CROPPING 2021-05-11T15:28:41+08:00 Ulysses A. Cagasan ulycagasan@vsu.edu.ph Rogelio N. Coral ulycagasan@vsu.edu.ph <p>The development of promising genotypes is a continuing activity by the breeders to give the farmers more choices of varieties to plant. This study aimed to evaluate, determine, and select promising peanut genotypes to be recommended to NSIC as new peanut varieties. There are 10 treatments, including the 3 check varieties, used in this study: T<sub>1</sub>-JONES, T<sub>2</sub>- ILOCOS RED, T<sub>3</sub>- LG Pn 06-36-2, T<sub>4</sub>- LG Pn 08-4a-2, T<sub>5</sub>-LG Pn 06-3-4-3a, T<sub>6</sub>-CVRC Pn 2011-002, T<sub>7</sub>- CVRC Pn 2011-001, T<sub>8</sub>-NSIC Pn19, T<sub>9</sub>- NSIC Pn14, T<sub>10</sub>- NSIC Pn18. <sub>&nbsp;</sub>The experiment was arranged in a Randomized Complete Block Design (RCBD) having the &nbsp;10 treatments replicated 3 times. Results showed that genotypes LG Pn 06-3-4-3a (T<sub>5</sub>), CVRC Pn 2011- 002 (T<sub>6</sub>), and CVRC Pn 2011-001 (T<sub>7</sub>) matured the earliest at 82-90 days comparable to check variety NSIC Pn14. &nbsp;Moreover, LG Pn 06-36-2 (T<sub>3</sub>), LG Pn 08-4a-2 (T<sub>4</sub>), LG Pn 06-3-4-3a (T<sub>5</sub>), CVRC Pn 2011- 002 (T<sub>6</sub>) attained the shortest plant height at 84-94 cm, comparable to the 2 check varieties NSIC Pn14 and NSIC Pn18. Genotypes planted during dry season produced a significantly higher weight of pods at an average of 2,862 kgha<sup>-1 </sup>and average total seed yield of 1,796 kgha<sup>-1</sup> than wet season cropping at 2,361 kgha<sup>-1 </sup>mean pod yield and 1,523 kg ha<sup>-1</sup> seed yield. Moreover, all peanut genotypes are resistant to moderately resistant to insect pests and diseases. Hence, it is recommended to plant peanuts during dry season cropping as it provides a higher grain yield than wet season cropping under Leyte conditions.</p> 2021-01-01T00:00:00+08:00 Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/264 Design of a Concentrated Solar Power System Using Computational Fluid Dynamics 2021-12-14T08:39:52+08:00 Renyl B.

Moran aristotle.ubando@dlsu.edu.ph Aristotle T. Ubando aristotle.ubando@dlsu.edu.ph <p>Concentrated solar power (CSP) is an alternative approach to harnessing the sun's power to generate renewable energy. As the requirement for the generation of energy grows, the demand for concentrated solar power also increases. Recently, efforts in using CSP technology to generate renewable energy have been adopted globally, with a 6.45 GW capacity installed. With plans of the Philippines to further strengthen the country's energy production and enhance the production of renewable energy in Mindanao, this study proposes to design a CSP specifically for Davao City using a computational fluid dynamics approach. The parabolic dish and a receiver can accommodate a concentrator dish of 10 meters in aperture diameter for installation in Davao City. The design scale-up of the concentrator is then assessed with its efficiency using ANSYS Fluent. In addition, SolTrace and the fluent discrete ordinates radiation model can predict the potential thermal energy extracted from solar radiation. The results show the heat flux pattern in the CSP receiver entrance.</p> 2021-12-14T00:00:00+08:00 Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/266 The Simulation of Water Level Using Delft3D Hydrodynamic Model to analyze the case of coastal Inundation in Pontianak 2021-12-14T08:48:25+08:00 Kuntinah tina.kuntinah@gmail.com Imma Redha Nugraheni tina.kuntinah@gmail.com Randy Ardianto tina.kuntinah@gmail.com <p>Several Indonesian coastal areas are prone to tidal flooding, one of which is Pontianak. High tides can trigger floods due to astronomical and meteorological factors. This study discusses the Delft3D hydrodynamics model’s performance in alluding to sea level and wave height in 4 cases of tidal flood events. Final Data (FNL) Global Operational Analysis from NOAA and tidal component data from oceananomatics are used to the Delft3D model. The model output consists of sea level is verified using tide gauge observation data from BIG. This is then used to analyze sea level to 4 flood events with the accumulated rainfall data from GSMaP, wind, pressure from ECMWF, and rainfall observations to describe the hydro-meteorological conditions. Based on four sea-level simulation cases, the Delft3D hydrodynamic model can perfectly reproduce the sea-level rise pattern. This can be seen from the correlation value of 0.93 - 0.96.&nbsp; Even though the simulated seawater level's value has a high error, it was significantly resolved after the datum correction (with a decrease in error of ±7-11 cm). Generally, the most dominant hydro-meteorological conditions affecting the level of flood events are waves and the direction (45°-90° towards the Pontianak Coast) and speed (4-16 knots) of the wind.</p> <p>In some cases, heavy rain can exacerbate tidal flooding conditions if it coincides with high sea-level conditions. It can obstruct the river's flow into the sea and cause water to overflow on land. This research can be used to consider making early warnings of tidal flooding in coastal areas, especially Pontianak. In addition, it is better to use forecast data (GFS) to make predictions and early warnings of tidal flooding.</p> 2021-12-14T00:00:00+08:00 Copyright (c) https://journal.evsu.edu.ph/index.php/itmj/article/view/269 Effects of Vermicompost Amelioration on the Soil Properties, Yield, and Profitability of Mungbean (Vigna radiata L.) 2022-01-05T11:59:22+08:00 Cornista Delliah ulycagasan@vsu.edu.ph Ulysses A. Cagasan ulycagasan@vsu.edu.ph <p>Vermicompost amelioration is essential to the development of any crop. Mungbean does not need more nutrients, especially Nitrogen, because it can produce N through microbial nitrification. This study aimed to determine the effects on the soil properties, appropriate rates, and the profitability of vermicompost amelioration on mungbean production. The treatments were as follows; T<sub>1 </sub>- no vermicompost (control); T<sub>2 </sub>- 1 t ha<sup>-1</sup> vermicompost; T<sub>3</sub>- 2 t ha<sup>-1</sup> vermicompost; T<sub>4 </sub>- 3 t ha<sup>-1</sup> vermicompost; T<sub>5 </sub>- 4 t ha<sup>-1</sup> vermicompost and T<sub>6</sub>-30-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>0<sub>5,</sub> K<sub>2</sub>0 as the positive control. The study was laid in RCB Design with three (3) replications. The results revealed that the application of 4 tha<sup>-1</sup> of vermicompost significantly increased the number of days from planting to flowering but high in LAI. Likewise, the weight (g) of 1,000 seeds and the total grain yield (tha<sup>-1</sup>) were also increased. The heaviest weight of 1,000 seeds was obtained with 4 t ha<sup>-1</sup> of vermicompost and 30-30-30 kg ha<sup>-1</sup> N, P<sub>2</sub>0<sub>5</sub>, K<sub>2</sub>O resulted in obtaining the highest grain yield. Application vermicompost 4 t ha<sup>-1</sup> vermicompost obtained a higher gross margin of PhP28,300.00 among the vermicompost applied plants comparable to the positive inorganic control plants of PhP30,410.00. Therefore, it is recommended that the farmers use an organic fertilizer at 4 tha<sup>-1</sup> of vermicompost for legume production to sustain the soil's fertility and productivity.</p> 2021-12-20T00:00:00+08:00 Copyright (c)
