Abstract

The purpose of this study was to determine the effect of fertilizer application types such as wasted tea fertilizer, leaf litter fertilizer, and market wasted fertilizer on growth and yield of pakchoy mustard. The experimental design was Mono factorial Complete Randomized Design with 8 treatments and 3 replications. The treatments were without fretilization (A0), Tea Wasted fertilizer (A1), Leaf Litter fertilizer (A2), Market Wasted fertilizer (A3), Tea Wasted fertilizer + leaf litter fertilizer (A4), Tea Wasted fertilizer + Market Wasted fertilizer (A5), leaf litter fertilizer + Market Wasted fertilizer (A6), Urea fertilizer 300 kg/ha (A7). Each treatment was replicated in three times and produced 24 experimental units with experimental plots area of 1 m x 1.5 m. The observed parameters were plant height, number of leaves, leaf area index and fresh canopy production. Data were analyzed by Analysis of Variance and continuedby Duncan Multiple Range Test (DMRT) 5%. The results showed that fertilizer treatment of various types of organic waste fertilizer Tea Wasted fertilizer, Leaf Litter fertilizer, Market Wasted fertilizer, Tea Wasted fertilizer + leaf litter fertilizer, Tea Wasted fertilizer + Market Wasted fertilizer, leaf litter fertilizer + Market Wasted fertilize resulted in plant height, number of leaves, fresh leaf canopy production significantly different from treatment without fertilization and urea fertilization. The best result of fresh canopy production was found in the treatment of market waste fertilizer weighing 2,778.47 g / m², the fertilizer application of market waste fertilizer and the combination treatment of tea and market waste fertilizer yielded the best plant height with 31.16 cm, the combination treatment of waste fertilizer Tea and market produces the best leaves as much as 12.44 leaflets, and fertilizer treatment of tea waste fertilizer, market waste fertilizer, tea waste fertilizer + market waste fertilizer, and leaf litter fertilizer + market waste fertilizer yield value index of leaf area 1.23. Keywords : Organic Fertilizer, Organic Wasted Fertilizer, Pakchoy

Abstract

This research has an aim to observe the production of lettuce (Lactuca sativa L.) on hydroponic technology of floating system with red and blue LED (Light Emitting Diode) at night. This research was conducted inside the Screenhouse in which located on the top of Griya Kads House building, Bulusan Village, Tembalang Sub-district from May to June 2017. The research was conducted by 3x3 factorial experiments in Nested Design with 3 replications. The first factor was 0, 1.5 and 3 hours irradiation of red and blue LED lights at night. The second factor was 3, 5 and 7 ml/liter of AB mix nutrient concentration which was nested in the first factor. The data collected were fresh weight, dry weight and root canopy ratio. The results of the study showed that the treatment of AB mix nutrient concentration had no significant effect on all parameters. The production of lettuce with level of 5 ml concentration of AB mix was quite good, yet 3 ml and 7 ml levels didn’t improve lettuce production. The duration of red and blue LED irradiation only resulted in an increase in the production of canopy fresh weight. This research can be concluded that 3 hours was sufficient to give the good results to improve the results of lettuce plants production. Keywords : Lettuce Production, AB Mix Nutrition, Red and Blue LED.
