| Abstract The glycerin by-product of the production of biofuels (biodiesel) has possibility of agricultural use, but the scientific information is restricted. The objective of this study was to assess the effect of glycerin rates in the absence and presence of potassium fertilization on soil microbial activity, nutrition and production of beet (Beta vulgaris). The experiment was carried out in a greenhouse at Universidade Estadual Paulista, Jaboticabal, Brazil, using beet cv. Early Wonder, grown in pots with samples of Alfisol. The experimental design was randomized block, treatments were 0, 50, 100, 200 and 400 m3 ha-1 of glycerin, in the absence and presence of potassium (150 mg dm-3), with four replicates. Electrical conductivity, respiratory activity,... |

| Village level root crop processing system in the Philippines was evaluated using sweetpotato (cv. Kogane sengan and Shiro satsuma) as materials. The PRCRTC chipper/grater had more pronounced power fluctuation in grating than in chipping and peaking during the loading of the roots. The grinder had the highest energy requirement than the other machines，but the power fluctuation was relatively stable regardless of the amount of materials loaded. The finisher had a stable power fluctuation，and its power increased as either the loading rate or rpm was increased. Size and weight of chips and fineness modulus of grates were affected by the rpm of the blades. Percent recoveries of dried chips，fine flour and dried grates for Kogane sengan，at 12% moisture content，... |

| Voraussetzungen für einen erfolgreichen Anbau von Verarbeitungskartoffeln sind außer einem hohen Ertrag vor allem die von der Kartoffel verarbeitenden Industrie geforderten produktspezifischen Qualitäten für Pommes frites und Chips. Für die Verarbeitung zu Pommes frites muss z.B. ein hoher Anteil großfallender Knollen realisiert werden oder bei Chipskartoffeln bestehen strenge Vorgaben für die Gehalte an reduzierenden Zuckern. Um hohe Zuckergehalte zu vermeiden, erfolgt die Kartoffellagerung bei 8°C, was erhöhte Ansprüche an die Lagerfähigkeit bedeutet. In dem gemeinsam von der Universität Kassel (FG Ökologischer Land- und Pflanzenbau, Projektleitung), der FAL (Institut für ökologischen Landbau), der Universität Kiel (Institut für Pflanzenbau und... |

| Kann im Ökologischen Kartoffelanbau die Verunkrautung bis zum Bestandesschluss mechanisch erfolgreich kontrolliert werden, so bleibt nach Absterben der Bestände durch Krautfäulebefall oder geringe Nährstoffnachlieferung das Problem der einsetzenden Spätverunkrautung. In früheren Untersuchungen von Kainz et al. (1997) und Haas (1999) wurde die Reduzierung von Nährstoffverlagerung und Erosion durch Untersaaten in Kartoffeln geprüft. Im Projekt „Leitbetriebe Ökologischer Landbau in Nordrhein-Westfalen“ wurde in den Jahren 2005 bis 2007 auf insgesamt acht Standorten die Wirkung verschiedener Untersaaten (u.a. Ölrettich, Senf , Buchweizen) zu unterschiedlichen Saatzeitpunkten („letztes Häufeln“ und „Beginn Krautfäule“) auf die Spätverunkrautung insbesondere mit... |

| Biodynamic farming is the oldest organic farming movement in Germany. Since Dr. Rudolf Steiner’s “Course on Agriculture” held in 1924, the number of biodynamic farmers in Germany has grown continuously, with 1,317 farmers currently producing on 47,592 ha. One of the most distinctive aspects of biodynamic farming is the use of the so-called biodynamic preparations, which are applied in homeopathic doses. Biodynamic preparations are supposed to improve plant growth and food quality, minimising natural variations. This paper deals with investigations of influences of these preparations and increased manure application on potato yield and tuber quality. The results are drawn from extensive research on organic potato production carried out by several institutes... |

| A batata-doce é uma hortaliça que se destaca pela versatilidade no uso, podendo ser empregada tanto na alimentação humana como animal. Seu cultivo é relativamente fácil e barato, o que, juntamente com sua adaptabilidade a variadas condições edafo-climáticas, viabiliza sua produção pelos agricultores familiares. Objetivou-se avaliar a produção de massa verde e massa seca da parte aérea para utilização na alimentação animal e a produtividade e a qualidade das raízes tuberosas de clones de batata-doce para utilização na alimentação humana. O delineamento experimental utilizado foi em blocos casualizados, com doze clones e quatro repetições. Foram avaliados clones de batata-doce pertencentes ao banco de germoplasma da UFVJM juntamente com as cultivares... |

| The aim of this study was to quantify the water consumption and the crop coefficients (Kc) for the potato (Solanum tuberosum L.), in Seropédica, Rio de Janeiro (RJ), Brazil, under organic management, and to simulate the crop evapotranspiration (ETc) using the Kc obtained in the field and the ones recommended by the Food and Agriculture Organization (FAO). The water consumption was obtained through soil water balance, using TDR probes installed at 0.15m and 0.30m deep. At the different stages of development, the Kc was determined by the ratio of ETc and reference evapotranspiration, obtained by Penman-Monteith FAO 56. The crop coefficients obtained were 0.35, 0.45, 1.29 and 0.63. The accumulated ETc obtained in the field was 109.6 mm, while the ETc... |

| Potatis angrips lätt av potatisbladmögel, särskilt vid ekologisk odling eftersom möjligheterna att bekämpa sjukdomen är sämre. Då potatisen angrips av bladmögel måste den blastdödas för att förhindra smittspridning till knölar, mark och omgivning. I och med att potatisen har blastdödats kan det inte längre ske någon ytterligare inlagring och knöltillväxten avbryts. Det har naturligtvis stor betydelse när angreppet sker. Är det tidigt på säsongen kan skördeförlusten bli mycket stor. Målet med projektet är att ta fram tillväxtkurvor för olika potatissorter, dels i en frisk gröda och dels i en potatisgröda som angripits av bladmögel. Avsikten är att med hjälp av dessa kurvor beräkna effekten av olika grader av bladmögelangrepp och beräkna knölskördens storlek... |

| Estudaram-se os efeitos do plantio direto em cobertura morta de aveia-preta e do consórcio com Crotalaria juncea, em sistema orgânico de produção de inhame, em ensaio na EE de Nova Friburgo(Pesagro-Rio), região serrana do estado do Rio de Janeiro. Utilizouse o delineamento de blocos ao acaso com quatro repetições, em esquema fatorial 2 x 2, onde os tratamentos corresponderam ao: modo de plantio (direto ou convencional) e modo de cultivo (monocultivo ou consórcio com crotalária). O cultivo consorciado com a leguminosa promoveu maior altura nas plantas do inhame, assim como reduziu a queima de folhas pelos raios solares. A população infestante de ervas espontâneas foi mais efetivamente controlada com a combinação entre consórcio e plantio direto. Nenhum dos... |
