Abstract

Hydroponic crop cultivation generally uses AB mix nutrient. However, the expensive price of AB Mix nutrient caused increasing production costs. In addition to the expensive price, the availability of AB Mix is also limited. As an alternative, there is a need for more affordable fertilizer such as compound fertilizer and foliar fertilizer. The purpose of this study was to (1) determine the best compound fertilizer concentration to growth and yield of Pakcoy; (2) determine the best foliar fertilizer concentration to growth and yield of Pakcoy; (3) determine the interaction between compound and foliar fertilizer to growth and yield of Pakcoy. This study was used Split Plot Randomized Block Design consist 2 replicated. Main plot was compound fertilizer concentration and sub plot was foliar fertilizer concentration.The resulted of this study was (1) 2.5 g/L compound fertilizer concentration provide the best growth and yield of Pakcoy; (2) there was no significant effect of foliar fertilizer concentration; (3) there was no interaction between tho treatnments.

Abstract

Curly red chilies are one of the horticultural products that have the potential to be developed because they have high economic value, however the production of curly red chilies in Lampung Province has continued to decline in the last 4 years. One way to increase production value is to increase soil fertility by increasing fertilization. Fertilization is carried out to replace nutrients lost due to rainwater by using fertilizer containing the elements N, P and K, one of which is KNO3 and KH2PO4 fertilizer. The aim of this research is to find out which combination of KNO3 and KH2PO4 is better and to find out whether the single application of KNO3 and KH2PO4 is good for the growth and yield of curly red chili plants. The research used a factorial randomized block design consisting of 2 factors. The first factor is the concentration of KNO3 fertilizer, with 3 levels, namely 3; 4; 5g/l. The second factor is the concentration of KH2PO4 Fertilizer, with 3 levels of 3,5; 4,5; 5,5g/l. Each treatment was repeated 3 times, so there were 9 treatment combinations and 27 experimental units. The variables observed were plant height, stem diameter, number of shoots, fruit weight per plant, number of fruit per plant and root length. Potassium nitrate (KNO3) fertilizer treatment with a concentration of 5 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth in plant height. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth including the number of branches and stem diameter. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 4,5 g/l had a significant effect on plant yields including the number of fruit/plants and the weight of the fruit/plant.

Abstract

NFT hydroponic is a plant cultivation technology that allows plant roots to grow on a shallow nutrient layer on the narrow field. The goal of this study was to evaluate the best NPK 16-16-16 fertilizer concentration and planting media, as well as the combination of the best NPK 16-16-16 fertilizer concentration and planting media, on the growth and yield of pakchoy (Brassica rapa L). This study used a split plot in factorial randomized block design. The first factor is the concentration of AB mix fertilizer as a control at 1400 ppm (N1) and the concentration of NPK fertilizer, namely: 758 ppm (N2), 1000 ppm (N3). The second factor element is the type of planting medium, which consists of 6 media: rockwool (M1), cotton (M2), sponge (M3), fern (M4), charcoal husk (M5), and cocopeat (M6), with 2 repetitions and 18 treatment combinations. Plant height (cm), number of leaves (pieces), leaf width (cm), leaf length (cm), wet weight of sample plants (grams), and dried weight of plants (grams) were the observation variables. In comparison to an NPK nutrient concentration of 1000 ppm, providing an NPK fertilizer concentration of 758 ppm resulted in better growth and yield in the parameters of number of leaves, wet weight, and dry weight of pak choy plants. Using husk charcoal as a planting medium resulted in superior growth and results in the plant height, number of leaves, leaf width, leaf length, and wet weight of pakchoy plants.
