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.

The productivity of forage depends on the availability of nutrients in the soil where it is grown, so fertilization to replace harvested produce is absolutely necessary. This study aims to study the response of gamal and indigofera forage on application of inorganic and organic fertilizers. Research using a completely randomized design factorial pattern of two factors, the first factor is the type of plant (G = Gamal; I = Indigofera) and the second factor is the type of fertilizer (T = without Fertilizer; A = Inorganic fertilizer NPK; K = commercial organic fertilizer; O = conventional organic fertilizer; B = bioorganic fertilizer), repeated 4 times so that it consists of 40 experimental units. The variables observed were plant height, number of leaves, stem diameter, leaf dry weight, stem dry weight, total dry weight of leaves, ratio of dry weight of leaves/stems and leaf area per pot. The results showed that there was no interaction between plant species and types of fertilizer in influencing the response of gamal and indigofera plants. Plant species have a significant effect on stem diameter, while fertilizer types have a significant effect on plant height, leaf dry weight, total dry weight of leaves and leaf area per pot. Based on the results of the study it can be concluded that the response of gamal plants is similar to indigofera, all types of fertilizers can improve the response of plants and organic fertilizers produce the same crop response with inorganic fertilizers.

The experiment was carried out to determine the effects of heat stress on some growth parameters like shoot height, leaf area, fresh weight, dry weight as well as the accumulation of chlorophylls in Carica papaya. Seedlings of C. papaya were exposed to prior heat stress at 40 °C. A group of plants was placed in a Gallenkamp oven for four hours; another group of plants was placed in the oven for eight hours while the third group of plants was placed in a dark cupboard for the period of eight hours. Sampling was carried out at weekly intervals starting from seven days after treatment. Plants were randomly picked from each of the three treatments. Three replicates were used for each parameter. The results obtained from the study showed that there was an increment in the shoot height, leaf area, fresh weight and dry weight from the beginning to the end of the experimental period. However, the accumulation of chlorophylls did not follow a particular pattern. The analysis of variance carried out on the data obtained showed that heat stress had a significant effect on the petiole length, shoot height, leaf length, leaf width, leaf area, fresh weight and dry weight. Heat stress, however, did not produce a significant effect on the accumulation of chlorophylls a and b and total chlorophyll.

Reduction Effect

The spindliness of tomato transplants grown at high densities in a greenhouse was reduced by an ethephon spray or intermittent vibration of the seedlings with air movement. Either treatment reduced the following growth parameters: plant height, height-to-stem-diameter ratio, stem diameter, fresh weight, and dry weight. One ethephon spray alone reduced the height and improved the stalkiness of the seedling. Vibration of the plants with air movement had an even greater height-reduction effect while a combination of the two treatments was the most effective in producing the stalkiest transplants.Key words: Lycopersicon esculentum, plant height, stem diameter, tomato, growth regulator

SummaryThe utilization of lignocellulolitic emptyfruit-bunches of oil-palm (EFBOP) material asstraw mushroom (Volvariella volvacea) mediacould produce short chain organic carbon andnutrients which may be available for growth ofplant. This research was aimed to determine theeffect of spent mushroom media amendmentderived from empty fruit bunches of oil palm(SMEB) as organic fertilizer on the growth andnutrient uptake of oil palm seedling. Theexperiment was conducted at greenhouse usingacid soil. Oil palm seedling was grown in 60 x 50cm polybags. The experiment was carried out toexamine 20 treatments i.e. combinations of fourlevel of SMEB (0, 25%, 50%, and 75% w/w) andfive dosages of conventional fertilizer (0, 25%,50%, 75%, and 100%) recommended dosages.The experiment was conducted using completerandomized design with factorial type. Theresearch showed that the amendment of SMEB atthe level of 25% could increase the height ofseedling, fresh weight of root, stem, and seedlingsas well as dry weight of oil palm stem. However,for leaf dry weight, a higher addition of SMEB upto 50% was needed. Fertilizing at 25% ofrecommended dosage could increase the seedlingheight, fresh weight of stem and leaf while forseedling fresh weight and leaf number, higheraddition of fertilizer up to 50% was needed.Significantly higher uptake of K and Mg wasobserved on the amendment of 75% of SMEB.The higher addition of SMEB (up to 75% w/w)did not decrease any growth parameters andnutrient uptake. However, the addition of 100%of recommended chemical fertilizer tended todecrease various growth parameters and uptakeof N, P, K, and Mg of oil palm seedling.RingkasanPenggunaan bahan lignoselulosa sebagaimedium jamur merang (Volvariella volvacea)diketahui dapat menghasilkan senyawa karbonrantai pendek demikian pula hara tersedia,sehingga diduga bahan ini dapat digunakansebagai pupuk organik untuk tanaman.

This study aims to determine the differences in the growth response of green curly lettuce to the differentiation treatment of LED lighting with different spectrum in indoor hydroponics. The research was conducted from October to November 2017. The experimental design used was experimental with 1 lighting factor with 5 levels, there are sunlight (P0), LED 20% blue: 80% red (P1), LED 80% blue: 20% red (P2), 50% blue LED: 50 % red (P3), and 100% white daylight (P4). Observational variables included plant height, leaf number, leaf area, leaf color, total wet weight, leaf wet weight, wet root weight and dry weight of the plant. The result of this experiment showed that LED irradiation have affect the treatment are plant height, leaf number, leaf area, chlorophyll content, fresh weight of harvest, root length, and dry weight of brackets. While those that have no significant effect are the wet weight of the roots. The results showed that between LED irradiation treatment L1, L2, L3, and L4 showed that treatment L2 with 80% blue spectrum composition: 20% red showed better growth based on: high plant, chlorophyll content, and root length. Treatment with L4 with white LED showed better growth based on the number of leaves, leaf area, fresh weight of harvest, root wet weight, and dry weight of total biomass. The results below the sunlight better than the LED irradiation treatment, because the intensity of LED far low and lack of controlled environmental conditions technology and management for growing lettuce. In all of LED treatment still looked etiolation because light intensity was not optimal yet.
