Abstract

Litter is the main source of organic matter and nutrient entrance in shade grown coffee agroecosystems.Shade trees provide ecological and economic benefits in coffee agro-ecosystems thatindicate the key factor for sustainable coffee production. This study examined the role of litter onnutrient (N and P) returning in coffee agro-ecosystems. The experimental plots of Coffea canephorawere constucted at benchmark site of Conservation and Sustainable Management of Below-GroundBiodiversity (CSM-BGBD), in Sumberjaya Subdistrict, West Lampung, Indonesia, during 2007-2010.Types of shade trees to be examined were legume shade trees of Gliricidae sepium and Erythrinasububrams, non-legume tree of Michelia champaca, and no shade tree. The results showed that: (1)kind of shading determined litter productivity of coffee agro-ecosystems. Litter productivity of coffeeagro-ecosystems with shade trees increased coffee bean yield, (2) litter was an important source of Nand P that returned into the soil. Amount of nitrogen from litter biomass has linier effect on coffee beanyield.

Abstract

To improve yield and cup quality, mature coffee tree as rootstock could be grafted with scion of selected genotype. This research aimed to study growth performance of mature trees resulted from intra and inter-specific grafting on Robusta coffee. The research was arranged in Randomized Complete Block Design with 3 replications. There were 12 treatments of entrees/under-stump genotype for coffee grafting including 8 treatments of intraspecific local Robusta/Robusta grafting and 4 treatments of interspecific coffee grafting of Robusta/Liberica and Arabica/Robusta. The results showed that intraspecific grafting of Robusta/Robusta, Robusta/Liberica, and Arabica/Robusta resulted in grafting mortality of 9.8%, 10.9%, and 24.8%, respectively. Until 28 weeks after grafting, branch growth variables were significantly affected by scion/rootstock of Robusta/Robusta, Robusta/Liberica, and Arabica/Robusta grafting. Grafted Arabica/Robusta coffee showed the poor growth performance. In second year of Robusta/Robusta and Robusta/Liberica growth, generative growth of cherry inflorescence per branch and number of cherries per inflorescence were not affected by scion and rootstock genotypes. Leaf and branch growth were very important variables correlating with other variables.

Abstract

Organonitrofos is one type of organic fertilizer capable of providing macro nutrients that more than other organic fertilizers, particularly nitrogen and phosphorous from the compost of a mixture of fresh manure and rock phosphate using Microbial N2-fixer and P-solubilizer. Research purpose was to study the effect of organonitrophos combined with inorganic fertilizer on the growth, production, yield of sugarcane, and determining the most effective combination of agronomically and economically in up landsugarcane. Research consisted of 5 treatments with 3 replications arranged in a randomized complete block design. The treatment were A (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl), B (300 kg ha-1 Urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl, 5,000 kg ha-1 Organonitrophos), C (150 kg ha-1 Urea, 75 kg ha-1 TSP, 150 kg ha-1 KCl, 10,000 kg ha-1 Organonitrophos), D (10,000 kg ha-1 Organonitrophos), and E (without fertilization). The results showed that the dose of fertilizer recommendation (300 kg ha-1 urea, 150 kg ha-1 TSP, 300 kg ha-1 KCl) supplemented with 5 ton ha-1 Organonitrofos compared to the doses of fertilizer recommendation (300 kg ha-1 Urea, 150 TSP kg ha-1, 300 kg ha-1 KCl) was not significantly different on growth, yield, productivity of sugarcane and sugar. While the addition of 10 ton ha-1 Organonitrofos at half dose of recommendation (150 kg ha-1 urea, 75 kg ha-1 TSP, and 150 kg ha-1 KCl) produced 106.11 tons ha-1of sugarcane and 7, 95 ton ha-1sugar being lower than the dose of fertilizer recommendation that produced 133.02 tons ha-1sugarcane and 10.72 ton ha-1 sugar resulting macro nutrients derived from half dose of fertilizer recommendation are not able to increase the productivity of sugarcane and sugar.Dose of fertilizer recommendation plus 5 ton ha-1 Organonitrofos was an effective dose of fertilizer agronomically while fertilizer dosage recommendation was the most efficient dose of fertilizer economically.Keywords :dry land, fertilizer, inorganic, Organonitrophos, sugar cane

Abstract

Oil palm (Elaeis guineensis Jacq.) is one of the important excellent crop plantations which have significance for the development of national farm and country source of foreign exchange earnings.Oil palm cultivation is mostly done on the ground of ultisol that have constraints phosphorus deficiency that needed improvement in the quality of the nursery with the utilization of arbuscular mycorrhiza fungi (AMF). The study aimed: (1) determine the best type of AMF in enhancing the growth of oil palm seedlings, (2) determine dose of NPK fertilize most appropriate for the oil palm seedling, (3) determine whether the response of oil palm seedlings to type AMF influenced by dose NPK fertilizer, and (4)determine the best dose of NPK fertilizer for each type of AMF. The treatment design is a factorial (6x2) arranged in randomize completely block design with 5 replications. The first factor is the type of AMF, design as without AMF, Glomus sp. Isolate MV 23, Glomus sp. Isolate MV 26, Entrophospora sp. Isolate MV 22, Entrophospora sp. Isolate MV 25, Entrophospora sp. Isolate MV 28.The second factor is number of NPK fertilize design as p1 (100 % from recomendation) and p2 (50 % from recomendation). Means homogeneity among the treatments were tested using Barlett test and the aditivity data were tested with Tukey test. Separation of means value were analyzed using Least Significant Difference (LSD) at 5% significance level. The results showed the interaction between the type and dose of NPK fertilizer AMF is can be concluded that (1) oil palm seedlings response to AMF inoculation type is determined by the dose of NPK fertilizer on the variable plant height, dry weight of root, and number of primary roots, 2) the optimum dose for each type of AMF are used based on the data root dry weight is a combination of 100% NPK fertilizer with each type of AMF, excepton the AMF types Entrophospora sp.

Abstract

Ethno-agronomy of Coffee Plantation Management in Sumberjaya West LampungDistrict.Study of ethno-agronomy is important for policy making to support sustainable coffee plantationand ecological services in cathment area. This paper reviewed tradition across ethnic in Sumberjaya,West Lampung on coffee plantation management. It showed that the ethno-agronomy of coffee plantationsin Sumberjaya was a unique local wishdom. Coffee agronomic practices in Sumberjaya were evolutingand integrating with shifting cultivation system. Coffee treeswere rotated with vegetables crop or shrub.In Sumberjaya, land uses were dynamic between forests, coffee field, crop field, and shrubs. Pre-cropping and inter-cropping ofvegetables in coffee fieldwas source of income for farmers before coffeehad attainedphase of yielding. So far coffee plantations in Sumberjaya were managed by traditional andless intensive practices including by planting shade trees, timber and multi-purposes treespecies. Coffeeagroforestry was alocal wishdom that impotant for land conservation of the catchment area.

Abstract

Legume nodulating bacteria (LNB), known also as rhizobia, are soil bacteria, which are able to form rootnodules and fi x nitrogen in the leguminous plants. The LNB availability in the soil depends on the type ofagroecosystem, where plant grows. In this study, we isolated LNB from the shrub agroecosystem in Sumatera,Indonesia, and obtained four selected bacterial strains. Among them, the isolate UGM48a formed root nodulein Macroptilium atropurpureum and showed highest number of nitrogenase activity. UGM48a also contains nifHand nodA genes. An analysis of the PCR-amplifi ed 16S rDNA and BLASTn analysis showed that UGM48adisplayed 96% similarity with Achromobacter xylosoxidans.

Abstract

Variability of Coffee Cultivars in Lampung. Province of Lampung is production region of Robusta coffee in Indonesia. Farmer plant seedling of progeny resulted in high variability of coffee bean production. High yield clones then were used as grafting material to improve coffee production. The research aimed to study variability of coffee cultivars in Lampung and factors affecting its production. Respondent farmers and coffee fields to be surveyed were determined by purposive sampling method from 3 district of West Lampung, Tanggamus, and North Lampung. Three sub-districts were taken from each district to choose a farmers group. The results showed that there were 27 cultivars found in location including 25 cultivars were Robusta coffee and the rest were Arabica and Liberica. In each district, the compositions of dominant cultivars were different. Farmers were able to describe the cultivars based on characteristics of fruits and beans, leaves, shoots, and branches. Some cultivars come from other province of outside Lampung. Dominance indices and richness of cultivars together with elevation level of coffee field had significant negative effects on coffee productivity, while fertilize doses had positive effects.

Abstract

Preliminary test on the effect of water extract from plants on rust incidence on coffee leaf disks at the latroratory. The objective of this study was to determine the influence of several water extract from plants on rust incidence on coffee leaf disk a laboratory condition. The study was done from March to June 2003. Treatments were arranged in a randomized complete block design with four replications, One experimental unit consisted of eight leaf disks with 2 cm in diameter. To prepare water extract, 1 00 g of plant or its part was homogenized with 100 ml sterilized distilled water.  After being passed through four layers of sterilized cheesecloth, the mixture was defined as the aliquot. Ten percent of the aliquot was sparyed on leaf disks before inoculation. As inoculum, uredospores developed on leaves under field condition were taken with sterilized scalpel and placed in sterilized distilled water and counted with hemacyometer to get suspension (4x105 uredospores per ml) spores per ml). Data on disease incidence were analyzed with ANOVA and Duncan test. The results showed that disease incidence was significantly reduced by water extract processed from the leaves of Piper betle, Azadirachta indica, and Eugeni aromatica, the rhizomes of Zingiber afficinale and Curcumq longa, stem of Cymbopogon citratus, Allium ascalonium, A.sativa, and copper fungicide. Disease was not significantly reduced in leaf disks sprayed with extract prepares from the leaves of Piper retrofractum, P. nigrum,  the rhizomes of Imperata cylindrica and Alpina galanga, A. cepa,Ageratum comysoides, and Elephantopus scaber.
