EFEK BIOCHAR DAN TEH KOMPOS TERHADAP PERTUMBUHAN DAN HASIL SELADA DARAT (Lactuca sativa L) DI TANAH VERTISOL SEMIARID
No full textImproving soil and plant productivity in semiarid regions was challenged by the climatic factors such low rain fall and high temperature in addition to limited availability of appropriate agricultural technologies. The objective of this field trial was to assess the effect of biochar and compost tea on the growth of curly leave lettuce grown in a semiarid region of West Timor. Two types of biochars (rice husk and sawdust) in combination with two types of compost teas namely Chromolaena odorata stem and guano at two rates (150 ml/plant and 250 ml/plant) were arranged in a factorial randomized completely block design 3 x 3 x 3 with 4 replicates. Soil parameters such as pH and electrical conductivity, and plant parameters such number of leaves, fresh weight were measured to indicate the treatment effects. The results indicated that soil temperature and soil bulk density were decreased, and soil moisture, soil electrical conductivity, number of leaves, total fresh weight, and root length were increased by added biochars and compost teas. Application of rice husk biochar at 10 t/ha in combination with guano compost tea at 250 ml/plant in increase the lettuce shoot fresh weight almost twice compared to the control. This results could be attributed to the improving soil productivity by added biochars and nutrients supply by the teas

No full textThe purpose of this study was to determine the dose of urea fertilizer and proper watering frequency on the growth of patchouli cuttings Aceh and whether there is interaction between the two factors. Factors urea fertilizer consists of 3 levels: 1 g/polybag, 2 g/polybag and 3 g/polybag. Watering frequency factor also consists of 3 levels: 2 times a day, 1 time a day and 2 days of watering.The results showed a significant effect of urea fertilizer on plant height at 15 DAP, however no significant effect on plant height age of 30, 45 and 60 DAT, the number and percentage of shoots grown at 15, 30, 45 and 60 DAP. Patchouli better growth obtained in the treatment of urea fertilizer dose of 2 g / polybag. The frequency of watering did not significantly affect plant height, number of shoots, a growing percentage of the age of 15, 30, 45 and 60 DAP. Better growth likely to be obtained at the frequency of watering treatment 1 a day.There is no real interaction between the dose of urea with the frequency of watering on plant height, number of shoots and the percentage is growing at 15, 30, 45 and 60 DAP

No full textThe study was conducted at Screen house of Department of Agrotechnology, College of Agriculture Petra Baliem Wamena. Altitude of place 1680 m asl June - July 2017. This research is a factorial experiment with the basic design of Randomized Completed Block Design (RCBD). This study consists of two factors that are arranged factorially. The first factor is the concentration of liquid organic fertilizer BioMethaGreen consisting of: without liquid organic fertilizer BioMethaGreen, 15 cc / l, 30cc / l. The second factor is caisim crop varieties which include: Tosakan varieties, Shinta varieties, Local varieties. The variables observed were plant height, leaf number, leaf area, wet crop weight, dry plant weight, and root volume. The results showed that the use of liquid fertilizer BioMethaGreen does not give effect to all growth variables and caisim plant yield. The use of three caisim varieties has a very real effect on all variables. There is no interaction between the use of BioMethaGreen liquid organic fertilizer and the use of three caisim varieties

No full textSelection of 3rd generation soybean mutants (M3) of Kipas Putih has been selected for tolerance of drought stress. The research was conducted at the Tissue Culture Laboratory of Faculty of Agriculture, Syiah Kuala University, Darussalam - Banda Aceh. Gamma ray irradiation was performed at Puslitbang Teknologi Isotop dan Radiasi BATAN, Pasar Jumat Jakarta. Seed of Varietas Wilis and Dering soy bean was used as control for drought tolerant and Kipas Putih was used as original variety. Selection was performed in vitro by using 20% Polyethylene Glycol (PEG). The results showed there were 8 genotype mutants categorized as tolerant to drought stress, ie KP100-26, KP100-28, KP200-31A, KP200-38, KP200-51, KP200-62, KP300-34, and KP300-47. Eleven mutan genotypes were categorized as medium tolerant and six genotypes were sensitive to drought. Selection of M4 generation selected lines are needed to find the drought tolerant and high-yielding mutant
EFISIENSI PEMUPUKAN NPK DENGAN APLIKASI FUNGI MIKORIZA ARBUSKULAR (FMA) TERHADAP P-TERSEDIA, SERAPAN P DAN PERTUMBUHAN BIBIT LADA LOKAL ACEH PADA MEDIA TANAH INCEPTISOLS
No full textThis research is aimed to analyze the efficiency of NPK fertilization by application of Arbuscular Mycorrhiza Fungi (AMF) to p-available, uptake p and growth of local pepper seeds in Aceh on soil media inceptisols. The research was conducted Agriculture Experimental Garden, Malikussaleh University. Implementation of the research was also conducted at Agroecotechnology Laboratory, Faculty of Agriculture, Malikussaleh University and Laboratory Center for Assessment Agricultural Technology (BPTP) Aceh. The study was conducted from January to December 2017. The study design was arranged in a Randomized Block Design with three replications. The first factor is dose of FMA with dose levels 0, 12,5; 25; and 37.5 g / plant. The second factor is NPK fertilizer with dose levels 0, 10, 20, and 30 g / plant. The observed variables included AMF infections in plant roots, analysis of soil chemical properties (pH H2O, and P-available); P-uptake, and plant growth (dry weight of the roots and dry weight of the canopy). The observed data were analyzed by using F test. The average comparison of treatments were analyzed by BNT test at 0.05 level. The results showed that the dose of AMF had no effect on soil pH value, P uptake and dry weight of canopy. The research revealed that the best NPK fertilizer dose was 10 g polybag-1 which increases the nutrient uptake of P and the dry weight of the canopy. The higher the doses of NPK fertilizer we used, it lowered the growth of the plant. We found that the best interaction happened in combination between the dose FMA 37.5 g polybag-1 with the dose of NPK 10 g polybag-1 The combination can increase the AMF infection, P-available and dry weight of roots. The higher the dose of AMF, the lower the need for NPK fertilizer. The use of AMF was efficient in the use of NPK fertilizer on local pepper cuttings in Aceh in soil media inceptisols in Reuleut
