| Se desarrolló un grupo de estudios sobre un suelo Ferralsol ródico (FAO UNESCO, 1990) com el objetivo de evaluar la inlluencia de la Irecuencia de inoculación con hongos micorrízicos arbusculares (HMA) sobre las poblaciones de rizobacterias inoculadas y el electo de estas combinaciones sobre los rendimientos en dilerentes secuencias de cultivos. Para ello se Ilevaron a cabo 4 experimentos de campo, establecido con un disefio de bloques ai azar, repetidos durante dos afios, donde se alternaron tres cultivos dilerentes, teniendo en cuenta las características dei sistema radical, las extracciones de cultivos y el aporte ai suelo de massa seca y nutrientes para establecer el orden dentro de cada secuencia. Los resultados mostraron que las poblaciones de... |

| Na busca por métodos de manejo com menor impacto ao ambiente e que se enquadrem nos sistemas orgânicos de produção, este trabalho teve o objetivo de avaliar preparados homeopáticos de plantas de tiririca e o adubo verde mucuna-preta (Stilozobium aterrimum Piper & Tracy) no controle da tiririca. O experimento foi desenvolvido em vasos, em casa de vegetação, na Fazenda Experimental Lageado, FCA-UNESP-Botucatu, no período de abril/maio de 2008. O delineamento experimental utilizado foi inteiramente casualizado, com três repetições, sendo os tratamentos constituídos por extrato aquoso da mucuna-preta, palhada de mucuna-preta em cobertura de solo e incorporada, preparados homeopáticos das plantas de tiririca, e a testemunha. O extrato aquoso da mucuna-preta... |

| Organic farming is challenged by perennial weeds such as Canada thistle. The increasing CO2 concentration levels causing temperature increase may lead to an increased photosynthesis and as a consequence elevated storage in underground perennating organs. In this study, we analyzed fructan, the main storage in Canada thistle, in juvenile and mature plants treated with different temperatures. Low temperatures caused higher concentrations of fructan in four weeks old plants. Proximal root fragments had higher amount of fructan than distal fragments. Regenerative ability from roots with different fructan concentrations was also associated to temperature and age. This implies that the timing of root fragmentation in autumn should occur earliest four weeks... |

| Zonas ripárias são áreas de saturação hídrica, permanente ou temporária, cuja principal função é a proteção dos recursos hídricos de uma microbacia. Essa pesquisa comparou a adequação do uso do solo de dois cenários de planejamento agrícola de uma microbacia: o cenário convencional, representando o método usualmente empregado, que apenas considera as classes de capacidade de uso da terra, e o cenário hidrológico, que inclui a delimitação e avaliação das zonas ripárias. Um estudo de caso foi realizado na Microbacia do Ribeirão São João (3.656 ha), no município de Mineiros do Tietê (São Paulo, Brasil). Mapas de Classe de Capacidade de Uso da Terra e de Adequação do Uso do Solo foram elaborados, utilizando o Sistema de Informação Geográfica (SIG), para a... |

| Feed value in form of FEsv (Feed unit / kg dry matter, for piglets) and FEso (Feed unit / kg dry matter, for sows), EDOM (Enzyme Degradable Organic Matter) and EDOMi (Enzyme Degradable Organic Matter, Ileum) is used in the feed evaluation system for pigs. Analysis of feed value have highlighted that there is a significant variation between varieties as well as due to an environmental variation between regions and the harvest year. The chemical analysis is, however, time-consuming and costly, and it is therefore desirable to have a rapid and less expensive method, which makes it possible to carry out more analyses in-situ. |

| 2012 was het eerste jaar waarin de systeemontwikkeling "PlantyOrganic" in praktijk is gebracht. Op de zes percelen zijn de gewassen geteeld die voorzien waren en zijn metingen verricht aan bodem en gewas. De gebruikte meststoffen waren slechts gedeeltelijk volgens het ontwerp omdat er nog geen voorraad aan maaimeststoffen was opgebouwd. De bodemstikstof is getoetst met metingen die in het stikstofmodel NDICEA zijn ingevoerd. De match tussen metingen en berekeningen is voldoende tot goed, met een enkele uitzondering. De gewassen zijn succesvol geteeld, met in opbrengst peen als uitschieter naar boven en zomertarwe als uitschieter naar beneden. Stikstof lijkt alleen in de bloemkool niet voldoende voorhanden te zijn geweest hoewel ook hier de opbrengst niet... |

| A tree is known by its fruits and a man by his achievements. Dr Phalguni Das Biswas is a scientist with a difference as his inventive genius could find its meaningful expression in delivering a quintessential system that provides a healing touch to the prevailing unstable agriculture by restricting productivity depletion, ecosystem pollution and food toxicity. He has published over 40 articles in international journals like Central European Journal of Experimental Biology and The International Journal of Science and Technology. There is a happy marriage of modern science with his repository wisdom of Vedic philosophy and its logical sublimation. His brain child Inhana Rational Farming (IRF) technology is the only technology in the organic world. More... |

| In intercropping, more than one crop species are cultivated simultaneously on the same piece of land, to promote interaction between species. To determine the effects on yield performance of intercropping of legumes and cereals, a meta analysis has been set up based on data from publications on this kind of field trials as found from an extensive search on Web-of Science. The effect of intercropping has been assessed by comparing yield in pure stand and in the intercrop of each species. Two measures were considered : i) The LER (Land Equivalent Ratio), which is a simple way to compare the pure yield with the intercropping yield by a sum of ratios and ii) the overall effect decomposed into sum of a ”selection effect” and a ”complementary effect” (Loreau... |

| The residual effect of cutting and grazing during the growing season was investigated in the spring and summer growth in an organic crop rotation with 1-4 year-old grass-clover mixtures of white clover (Trifolium repens L.) and perennial ryegrass (Lolium perenne L.) either with or without red clover (Trifolium pratense L.) and with and without slurry. The white clover mixtures had significantly higher yields in spring and summer in swards that were previously grazed compared to previously cut swards, when slurry was applied. The percentage of white clover in spring was considerably reduced by previous grazing and this caused the yield response of slurry application to be highest following grazing. A similar effect on the clover content was not found in the... |

| Karnataka state is a state of India with diverse agro-climatic zones.In 2001 it had a population of 53 million and 66% of population habitants living in villages. Agriculture is still major occupation in the rural areas of Karnataka and more than 90% of rural people are dependent on agriculture and agro-industries. However irregular rainfall patterns,pest attacks and poor nutrient management are resulting more frequently in crop failures. This has resulted in agrarian distress as with crop failures, farmers are unable to repay the loans. The government of Karnataka introduced Karnataka state policy of organic farming to decrease agrarian distress. In order to asses the impacts of this policy on agriculture, economic and ecological... |

| One core idea behind organic production is that cropping systems should be less dependent on resource import than conventional production and minimize negative environmental effects. This study aimed to test novel organic rotations, designed to reduce reliance on external resource import. We compared a conventional system (C) and an organic system relying on manure import (O1) to two rotations (O2 and O3), both relying on autumn cover crops for soil fertility, and in O3 green manure rows were left as intercrops. Resource import differed between 149, 85, 25 and 25 kg N ha-1 year-1 in C, O1, O2 and O3. Crop yields were lower in the organic systems (on average 82% of conventional yields), differing among crops, when based on the area grown with main crops.... |
