Vertical or multilayer farming is getting popular and more attention in Malaysia due to its effectiveness of space optimization. Planting density also another focus to maximize the production capacity with compromise of growth and yield. However, uneven lighting and shading was an issue on multilayer planting system in a greenhouse. Therefore, a study on the effect of layer and different planting distance on growth of Fan Pak Choy in a multilayer planting system was studied. This study was conducted in greenhouse at the Malaysian Agricultural Research and Development Institute (MARDI) using two factor factorial Randomized Complete Block Design (RCBD). The first factor is layer (L) which consists of 3 levels, namely below (L1), middle (L2) and top (L3). The second factor is planting distance (S) which consists of 3 distances arranged with 13cm (S1), 18cm (S2), 23cm (S3) in a single row. Parameters observed were plant height, number of leaves, leaf area, plant fresh weight, relative chlorophyll content, air temperature, relative humidity, light intensity and air speed. Top and middle layers show better results compared from below layer on plant height, number of leaves, leaf area, plant fresh weight and relative chlorophyll content. Planting distance of 13cm, 18cm and 23cm was not significantly different for all parameters except for plant fresh weight and leaf area which is 18cm (327.06g, 2482.77m²) gives better results followed 13cm (299.46g, 2181.91m²) and 23cm (229.70g, 1875.67m²) respectively. In summary, combination between layer and planting distance was significantly affect on yield of Fan Pak Choy.

Abstract

Vertical or multilayer farming is getting popular and more attention in Malaysia due to its effectiveness of space optimization. Planting density also another focus to maximize the production capacity with compromise of growth and yield. However, uneven lighting and shading was an issue on multilayer planting system in a greenhouse. Therefore, a study on the effect of layer and different planting distance on growth of Fan Pak Choy in a multilayer planting system was studied. This study was conducted in greenhouse at the Malaysian Agricultural Research and Development Institute (MARDI) using two factor factorial Randomized Complete Block Design (RCBD). The first factor is layer (L) which consists of 3 levels, namely below (L1), middle (L2) and top (L3). The second factor is planting distance (S) which consists of 3 distances arranged with 13cm (S1), 18cm (S2), 23cm (S3) in a single row. Parameters observed were plant height, number of leaves, leaf area, plant fresh weight, relative chlorophyll content, air temperature, relative humidity, light intensity and air speed. Top and middle layers show better results compared from below layer on plant height, number of leaves, leaf area, plant fresh weight and relative chlorophyll content. Planting distance of 13cm, 18cm and 23cm was not significantly different for all parameters except for plant fresh weight and leaf area which is 18cm (327.06g, 2482.77m²) gives better results followed 13cm (299.46g, 2181.91m²) and 23cm (229.70g, 1875.67m²) respectively. In summary, combination between layer and planting distance was significantly affect on yield of Fan Pak Choy.
