The aims of this research is to get the best concentration of cow urine as liquid organic fertilizer on rubber seed growth, to get the best fermentation time for cow urine as liquid organic fertilizer on the growth of rubber seedlings, and get the best interaction between concentration and cow urine fermentation as liquid organic fertilizer on the growth of rubber seedlings. The experiment was conducted in teaching farm of State Polytechnic of Lampung from January 2016 until June 2016. The treatments arranged in Randomized Block Design (RBD) with the factorial pattern consisting of two factors. The first factor was the concentration of cow urine, consisting of four levels: 15 cc.l-1, 30 cc.l-1, 45 cc.l-1 and 60 cc.l-1. The second factor was the duration of cow urine fermentation, consisting of five levels: 0 day, 7 day, 14 day, 21 day and 28 day. Rubber seedlings were used as plant indicator. Observations included plant height, number of petiole, stem diameter, stem girth, and dry weight of biomass. The results showed that the treatment of cow urine concentration had significant effect on plant height and number of petiole, but very significant effect on stem diameter, stem girth and dry weight of biomass. Likewise, the treatment of cow urine fermentation has significant effect on all observed variables except on the dry weight of biomass has a very significant effect. The interaction between treatment of cow urine concentration and cow urine fermentation did not significantly affect all variables except on dry weight of biomass had significant effect, i.e. cow urine concentration treatment of 45 cc.l-1 and fermentation of cow urine for 28 days resulted in dry weight of biomass higher rubber seedlings.Â Â Keywords: cow urine, fermentation, rubber seedlingsPermalink:Â http://jurnal.polinela.ac.id/index.php/AIP/article/view/651

The efforts to achieve optimal results in the development of oil palm cultivation one of which is the use of the planting medium. Palm oil seedlings require planting medium that has the chemical and physical properties are good. Media palm nurseries generally consist of topsoil are mixed with sand and organic matter which is expected to obtain a good medium fertility premises. Top soil needs more difficult, so we need to look for alternative media to growing media prenursery palm oil. This study used randomized complete design and experiment arranged in seven media with four replications. The applications method of media: 100 % topsoil (A), topsoil and salvinia compost (1:1) (B), topsoil and coir palm oil (1:1) (C), topsoil and salvinia compost (1:2) (D) , topsoil and coir palm oil (1:2) (E), coir palm oil and salvinia compost (1:2) (F) , topsoil , salvinia compost, and coir palm oil (1:1:1) (G). All data were analyzed for variance. Data analysis followed by separation of means using LSD test with significance level of 5%. The resulted showed that both time and applications method of topsoil have affect on growth component. The best application method was topsoil, salvinia compost, and coir palm oil increased dry weight and root dry weight. Keywords: Prenursey, topsoil , salvinia compost, coir palm oil

The effort to increase productivity of coffee plants in long dry season upland of Ultisol include application of Vesicular Arbuscular Mycorrhizae (VAM) on coffee plants, because its application only one time and its affect along a life time of coffee plant in the field. This study aims to determine the exact time and applications method of VAM on growth coffee seedlings. This study used 10 g VAM/polybag or 800 spores as basic treatment. This study used randomized block design and experiment arranged in factorial 3 x 5 with three replications. The first factor was the time of VAM application: given at nursery seedlings (W1), given at transplanting (W2), and combine of given at nursery seedlings and transplanting (W3). The second factor was the applications method of VAM: without VAM inoculant (C0), VAM inoculant placed around the coffee seedling root up to a depth of 2 cm below root (C1), up to a depth of 4cm below root (C2), up to a depth of 6 cm below root (C3), and VAM inoculant mixed with media planting (C4). All data were analyzed for variance. Data analysis followed by separation of means using LSD test with significance level of 5%. The resulted showed that both time and applications method of VAM have affect on growth component and root infection rate. The best application time was double application, i.e. combine of given at nursery seedlings and transplanting, and the best applications method was VAM inoculant placed around the coffee seedling root up to a depth of 2 cm below root, both of them increased plant height, stem diameter, leaf amount, long of root, and root infection rate.
