Full text linkThe objective of the research was to inventarize pests and diseases that associate with Xanthosoma undipes K. Koch at Mount Karang, Pandeglang, Banten Province. The research was conducted at field of Xanthosoma undipes K. Koch at Mount Karang and Biotechnology Laboratory of Untirta in Serang from May until July 2015. Samples of the Xanthosoma undipes K. Koch were choosen by purposive sampling methods from several points around Mount Karang. Several types of pests, predators, and diseases were found in the cultivation field of Xanthosoma undipes K. Koch. The pests were mantises, grasshoppers, snout beetles, long-horned grasshopper, big eyes dragonfly, ants, cockroaches, spiders, and butterflies. The predators including parasites were ants, flies, stone flies, and crickets. Two diseases were found i.e. leaf blight caused by Phytophtora colocasiae and sooty mold disease caused by Capnodium sp. The study also revealed that pests and diseases were also found in the storage process (post-harvest). Some warehouse pests such as pillbugs, ants and mites were found. The disease found were stem rot disease caused by Sclerotium rolfsii and soft rot caused by Lasiodiplodia theobromae.Keywords: Xanthosoma undipes K. Koch, Pest and disease

EFEK PEMBERIAN PUPUK HAYATI KONSORSIUM TERHADAP PERTUMBUHAN DAN HASIL TANAMAN SAWI (Brassica juncea L.)
Full text linkFertilizer is one of the important limited factor in plant cultivation system. Biofertilizer is a kind of fertilizer which improve nutrient availability in soil and subsequently plant yield. A research was carried out in village Waiheru, District Baguala, Ambon to determine the effect of different level of mixed biofertilizer on the growth and yield of caisim that grown on Alluvial. The research used Randomized Completely Block Design (RCBD) with three concentration of liquid biofertilizer, namely: 0.1%, 0.5% and 1%. Treatment control was without biofertilizer. The results showed that inoculation of liquid biological fertilizer at concentration of 1% improved growth and yield of caisim higher than the concentration of 0.1% and 0.5%. Inoculation of 1% biofertilizer increased the fresh weight of caisim shoot up to 37.36% compared to that of controls. While, fresh weight of caisim with biofertilizer of 0.1% and 0.5% was 24.52% and 28.94% respectively.Keyword: Ambon, Mixed Biofertilizer, Caisi

No full textThe aims of this research were to identify the effect of concentration growth regulator IAA and BAP as the basic MS medium against multiplication of banana plants by in vitro. The experiment was carried out at Laboratory of Biotechnology, Faculty of Agriculture, University of Sultan Ageng Tirtayasa from November 2013 to May 2014. The experiment used Completely Randomized Design which arranged in with two factors. The first factor was the concentration of growth regulators IAA which consisted of 4 levels (0 mg/L, 0.1 mg/L, 0.2 mg/L, 0.3 mg/L). The second factor was growth regulator BAP which consisted of 4 levels (0 mg/L.2 mg/L, l.4 mg/L, 1.6 mg/L), so that there were 16 treatment combinations, and repeated 3 times. The variables observed were number of shoots and growing percentage of the plant. The results showed that there was significantly interaction in number of shoot in 3 WAP. The best treatment was I1B1 (IAA 0,1 mg/L dan BAP 2 mg/L) for the number of shoot in 5 WAP. Keywords: IAA, BAP, Banana, Multiplicatio
PENGARUH WAKTU PENYIMPANAN BENIH DAN KONSENTRASI LARUTAN ASAM SULFAT TERHADAP PERTUMBUHAN BENIH JARAK (Jatropha curcas Linn.) DI PERSEMAIAN
Full text linkThe aims of the research were to study the growth of plants in the nursery and look for the optimum concentration of H2SO4 solution at certain storage duration that gives the highest dry plant weight in the nursery. Experiments were conducted in the seed laboratory and in the nursery of Faculty of Agriculture, Winaya Mukti University using randomized block design factorial with 2 factors. The first factor was the time and concentration of sulfuric acid solution i.e. Soaking 6 minutes in H2SO4 0.25%, 0.50%, 0.75% and 1.0%. The second factor was seed storage duration i.e. without being stored, 1, 2, and 3 months. The data was analized using linear quadratic regression method. The experimental results showed that there was interaction between seed storage time and concentration of sulfuric acid solution on leaf area and plant dry weight. The treatment without storage time and concentration of 0.75% sulfuric acid solution gave the best effect compared to other treatments. Zero minutes of storage followed with sulfuric acid concentration as much as 0.67% gave the highest dry plant weight of 28.193 g.Key words: Jarak seed, Concentration H2SO4, Seed saving tim

Full text linkCorn seed in the storage can be experience quality and quantity in July 1st 2017 decrease. In fact, it was caused by Sitophilus zeamais M. pest. The level of S. zeamais M. damage at corn seed could be over than 30%. This research was aimed to find the best concentration betel leaf powder to control S. zeamais M. on corn seed in the storage. Research was conducted at the Laboratory of Plant Pests Faculty of Agriculture University of Riau from October until December 2015. The research used a Randomized Completely Design (RCD) consisting of 5 treatments and 4 replications. The treatments tested were giving some concentration of betel leaf powder around 0, 2, 4, 6, and 8 g / 100 g of corn. Data were analyzed by analysis of variance. The result of that variance was tested further by Duncan's New Multiple Range Test. The result showed that S. zeamais M. which was given the betel leaf powder with different concentration showed the initial time of death, lethal time 50, daily mortality, total mortality, depreciation and accretion individual seed weight S. zeamais M. was different. The betel leaf powder with a concentration of 8 g/100 g of corn could control the S. zeamais M. pest.Keywords: Corn seed, Piper aduncum L., Sitophilus zeamais M
PENGARUH PUPUK HAYATI PADAT TERHADAP SERAPAN N DAN P TANAMAN, KOMPONEN HASIL DAN HASIL PADI SAWAH (Oryza sativa L.)
Full text linkOptimization of production rice plants can be achieved if the needs of macro and micro nutrients essential plant fulfilled. To achieve optimal rice yield can be done by proper fertilization based on the type, characteristics and nutrient content of fertilizers applied. Alternative to increasing rice yield can be done by applying biofertilizer in reducing the use of inorganic fertilizers. This experiment aims to determine the effect of Solid Biofertilizer (SBF) on nutrient uptake, growth, and yield and yield components of rice paddy fields. This research was carried out on the planting medium Inceptisols at Jatinangor used a Randomized Completely Block Design (RCBD) with 10 treatment combinations which replicated 3 times. The results showed that a dose of 1 NPK, combined with SBF ranging from ¼ dose, dose ½, ¾ and 1-dose showed gradual improvement to the uptake of N and P as well as yield and yield components of paddy.Keywords: Solid Biofertilizer, NPK Fertilizer, Paddy Yiel

Full text linkThe aim of the research was to determine the effect of the various dose Arbuscular Mycorrihizal fungi on the vegetative growth of soy bean plants (Glycine max L. merr) and to determine the optimal dose of Arbuscular Mycorrihizal fungi affecting the vegetative growth of soybean plants. The research was conducted in Cisonggom, Sajira districts, Parungsari village, Lebak Banten from September to December 2015. This research used Randomize Blocks Design with one factor (several dose mikoriza) with 6 level i.e. 2,5 g/polybag, 5,9 g/polybag, 7,5 g/polybag, 10 g/polybag and 12,5 g/polybag and repeated 4 times. Parameters of plants height, number of leaves, leaf area, root length, dry weight of plants, and the degree of infection of the roots were observed. The results indicated that treatment of Arbuscular Mycorrihizal fungi did not show significat effect on plant height at 1-6 week after plant, number of leaves at 1-6 week after plan, leaf area, and weight of soybeans plants. However, the provison of Arbuscular Mycorrihizal fungi showed significant effect on root length, and degree of infection of the roots with a dose of 7,5 g/polybag.
