Scientific Journal of Pure and Applied Sciences https://sjournals.com/index.php/sjpas <p>The Scientific Journal of Pure and Applied Sciences (SJPAS) is a peer reviewed multi-disciplinary specialist international journal aimed at promoting research worldwide in Agricultural Sciences, Biological Sciences, Chemical Sciences, Computer and Mathematical Sciences, Engineering, Environmental Sciences, Medicine and Physics (all scientific fields).</p> EuroPub Publishing Company en-US Scientific Journal of Pure and Applied Sciences 2322-2956 Defense Styles, approaches to learning and the mediating role of academic procrastination https://sjournals.com/index.php/sjpas/article/view/1711 <p>The present study belongs to the research that concerns the investigation of the relationship among academic procrastination, defense styles and approaches to learning. Specifically, it aims to explore the mediating role of academic procrastination in the relationship between defense styles and approaches to learning. The sample comprises 628 Greek university undergraduates (78% women and 22% men) who attend a four-year degree program. The questionnaires Defense Style Questionnaire-88, Procrastination Assessment Scale Questionnaire, Flourishing Scale, and HowULearn are used in the study. Results reveal the mediating role of academic procrastination in the relationship between maladaptive and adaptive defense style and approaches to learning. Academic procrastination seems to be a self-handicapping/defensive role between mental health variables and learning. Findings are discussed in the context of recent literature.&nbsp;</p> Patra Vlachopanou Evangelia Karagiannopoulou Copyright (c) 2024 Patra Vlachopanou, Evangelia Karagiannopoulou https://creativecommons.org/licenses/by-nc-nd/4.0 2023-01-28 2023-01-28 Effects of Farm Yard Manure and NPS Fertilizer Rates on Growth and yield of Garlic (Allium sativum L.) at Bale Highlands and mid-altitude, South-Eastern Ethiopia https://sjournals.com/index.php/sjpas/article/view/1774 <p><strong>&nbsp;</strong></p> <p><strong>ABSTRACT</strong></p> <p><em>Garlic is one of the most important crops worldwide ranking second after onion in order of importance and cultivation. </em><em>&nbsp;However, the productivity per hectare is low due to poor agronomic practices, lack of improved varieties, diseases and insect pests. Therefore, an on farm experiment was conducted to determine the effect of farm yard manure and NPS fertilizer rates on growth and yield of garlic and to identify economically feasible rates of farm yard manure and NPS fertilizer for garlic production. The treatments are consisted of factorial combinations of four levels of farm yard manure (0, 0.5, 1 and 1.5 tons’ ha<sup>-1</sup>) and five rates of NPS (0, 50, 100, 150, and 200 kg ha<sup>-1</sup>) and was laid out as a Randomized complete block designs (RCBD) in three replications. Analysis of variance showed that the plant height was significantly affected by NPS fertilizer while clove length was significantly influence by farm yard manure. On the other hand, the days required to reach 90% physiological maturity, number of leaves per plant, leaf length and number of cloves per bulb were significantly influenced by both FYM and NPS fertilizer.</em> The shortest days (130.8 days) and (131.2 days) to reach days to 90% maturity was observed without application of fertilizers.<em> The maximum plant height (70.50 cm) was recorded from 150 kg NPS ha<sup>-1</sup> which statistically at par with 200 and 100 kg NPS ha<sup>-1</sup>. The highest number leaves per plant (9.23) and (9.65) were obtained from 0.5 tone FYM ha<sup>-1</sup> and 150 kg NPS ha<sup>-1</sup> fertilizer respectively while the maximum leaf length (48.91) and (48.75) were recorded from 1.5 tones FYM ha<sup>-1</sup> and 150 Kg NPS ha<sup>-1</sup> respectively. The highest number of cloves per bulb (18.21) and (18.23) were recorded from 1 tone FYM ha<sup>-1</sup> and 100 kg NPS ha<sup>-1</sup> while the maximum clove length (2.49) was recorded from 0.5 tone FYM ha<sup>-1</sup>. The interaction effects of FYM and NPS fertilizer were significantly affected bulb weight, clove weight and total bulb yield. The highest bulb weight (30.77g) was obtained from 0.5 tone FYM ha<sup>-1</sup> and 150 kg NPS ha<sup>-1</sup> while the highest clove weight (2.83 g) was obtained from 0.5 tone FYM ha<sup>-1</sup> and 100 kg NPS ha<sup>-1</sup>. The highest yield (12.91 tone ha<sup>-1</sup>) was obtained from 0.5 tone FYM ha<sup>-1</sup> and 150 Kg NPS ha<sup>-1</sup> whereas the minimum yield (9.76 tone ha<sup>-1</sup>) was obtained from no application of FYM and NPS on garlic. The economic analysis also revealed that the highest net return of (</em><em>2316300 ETB </em><em>ha<sup>-1</sup>) with marginal rate of return (</em><em>308.84</em><em>%) was obtained at application of 0.5 tone FYM ha<sup>-1</sup> and 150 Kg NPS ha<sup>-1.</sup> Therefore, based on the results of the yield, growth, yield parameters and economic analysis use of 0.5 tone FYM ha<sup>-1</sup> and 150 Kg NPS ha<sup>-1.</sup> can be tentatively recommended for farmers for production of garlic in the study area.</em></p> <p><em>&nbsp;</em></p> <p><strong>Keywords</strong>: garlic, NPS, cloves, &nbsp;FYM, bulb yield</p> Chala Gutema Copyright (c) 2024 Chala Gutema https://creativecommons.org/licenses/by-nc-nd/4.0 2024-12-14 2024-12-14
