Abstract

The paitan plant contains allelopathic compounds for other plants so that the utilize of paitan plant as a source of liquid organic fertilizer (LOF) has not been widely applied. This research aimed to study the interaction between LOF dosage and appropriate application method of LOF to increase the growth of kailan plants. The research conducted at experimental garden of UIN Bandung from June-August 2016. The experimental design was a completely randomized design with two factors and replicated four times. The first factor was application methods (A), i.e. a1=direct application to the soil, and a2= spraying. The second factor was LOF dosage (T), i.e. t0: 0 ml plant-1, t1: 20 ml plant-1, t2: 40 ml plant-1, t3: 60 ml plant-1, t4: 80 ml plant-1. The growth parameters observed i.e. plant height (14, 21, 28, 35 and 42 Day after Transplanting (DAT)), leaf area 42 DAT, plant dry weight 42 DAT, and plant fresh weight 42 DAT. The data then analyzed with analysis of variance at a significant level of 5%. If the analysis of variance was significant, the Duncan multiple range test was used at α=5%. The research results showed there was no interaction between method of application with a various dosage of paitan LOF to all of the growth parameters. The application paitan LOF showed similar growth in terms of plant height, leaf area, plant dry, and plant fresh weight. The application method of paitan LOF direct to the soil or spraying to leaves can not increase kailan plant growth.

Abstract

Availability of land is one of the factors that can distract in farming, mostly on the horticultural plants like spinach vegetable. Spinach vegetable contained vitamin and mineral that needed by human. Hydroponic systems are technically can be used as a means of cultivating with such limitations. Hydroponics system with floating raft is able to provide nutrient elements required by plants, because roots can absorb nutrient elements anytime and positions the sub merged direct root nutrient solution. The purpose of this study was to determine the influence of various EC value (Electrical Conductivity) of the optimal fertilizer AB Mix towards growth of spinach (Amaranthus sp.). This research is held at Ciparanje, Jatinangor, Sumedang on May till June 2014. This research uses the random arrangement of a non-factorial group which have the values of EC (e1 = 1,5 mS cm-1 ; e2 = 1,8 mS cm-1 ; e3 = 2,1 mS cm-1 ; e4 = 2,4 mS cm-1 ; e5 = 2,7 mS cm-1 ; and e6 = 3,0 mS cm-1) with 4 replicates. Research results showed the level of e6 is capable of giving the best results against the height parameter, the vast index plant leaves, fresh weight, and dry weight. While on root length parameter, harvest index, and the shoot root ratio root does not significant different results for real. This is caused by nutrient solution pH which was not inaccordance with the needs of the crop of spinach with hydroponic systems. Hydroponic system on the recommended nutrient solution pH 5-6, nutrient solution pH while in the land ranged from 6-10. It became a bench mark growth of plants that were not optimal.
