In Malaysia, pineapple has been identified as a high-value non-seasonal tropic fruit, which is one of the top five fruits that shows a promising potential in the local and export markets. The variety of pineapple chosen in this study was MD2 hybrid. This variety is promoted for industrial cultivation by Malaysian Pineapple Industry Board (MPIB) because of its uniqueness as in uniformity and consistency for the size and ripeness compared to other varieties. Statistically, 90% of the pineapples in Malaysia are cultivated on peat soil while another 10% are cultivated on mineral soil. Highly weathered mineral soil lead to unfertile soil which inhibit crop growth. Thus, a field experiment was conducted to compare early growth performance of pineapple crop cultivated on mineral soil and peat soil. Based on t-test, growth performance including plant height, leaves length and leaves number showed no significant difference (p>0.05) except for leaf width. The leaf width of pineapple grown on mineral soil was significantly wider than cultivated on peat soil with significant difference of p = 0.015. The chemical analysis showed peat soil was significantly more acidic compared to mineral soil. Mineral soil was significantly higher in nutrients compared to peat soil especially the calcium (Ca) and magnesium (Mg). Meanwhile, peat soil was significantly higher in phosphorus (P) and potassium (K) content compared to mineral soil. From this study, it is found that with additional fertilizer, pineapple can be grown on mineral soil since the properties of soil can support the growth.
World is facing an increase of environmental concerns recently regarding on natural and synthetic fibers problems. Producing synthetic fibers may cost highly and create a few financial issues on the production matter. Moreover, synthetic fiber products have several disadvantages such as they are non-biodegradable. Some of them may cause health related problems and expose a significant risk. Researchers aimed to find the replacement for synthetic fibers with less cost production and renewable sources which lead to development of biomaterials-based composites production. Luffa is an eco-friendly crop, has been added as the new fibrous fruit with short harvest period. This study have applied a few practices using direct seeding and transplanting methods for low cost luffa production that aim for composites production. On the other hand, this study showed that transplanting (TP) method is better than direct seeding (DS) method based on the growth performance. TP method showed highest average of plant height (cm) and average total dry weight (g) of luffa fruits with 74.42±0.68 and 91.08±2.26 respectively whereas lower growth yield performance showed by DS method. Other parameters observed are the number of leaves and number of fruits which is a competent sources to the current composites sources, synthetic fibers. Hence, the results showed that luffa has the potential as a low cost and short harvest duration production plant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
