Growth and Present Status of Organic Farming in India and Global Level

Organic agriculture is growing rapidly as an alternative strategy to modern farming methods. India is home to 30% of total organic producers in the world having 2.30 million hectares. There has been a gradual increase in organic agricultural land in all the regions. According to the latest FIBL survey on organic agriculture worldwide, organic farming increases by 1.1 million hectares. Many countries are now focusing on organic farming because of healthy crops, fruits, vegetables that are produced purely by organic means, free from any harmful chemical fertilizers and pesticides and also eco- friendly. Organic farming is another way to overcome the problem of sustainability, global warming and food security.The present study attempts to analyse the Growth and Status of Organic Farming in India and Global level.

Organic onion growth, yield and storage improved by foliar sprays of microalgae and fulvic acid as a natural biofertilizer

The use of microalgae as natural biofertilizer in horticulture has recently been reported, while the use of humic substances is widespread. However, the combined use of microalgae with humic substances applied to plant leaves is still unexploited. Thus, the objective of this work was to combine fulvic acid (FA) with the Scenedesmus subspicatus microalga biomass (SC) as a natural biofertilizer applied via leaf in two onion cultivars in organic system. Four experiments were conducted: i) bioassays to verify the bioactive effect of FA, SC and combinations using the Vigna radiata model plant; ii) greenhouse pot experiment with foliar applications of FA, SC and combination in two onion cultivars; iii) field experiment in organic system with foliar applications of FA, SC and combination in two onion cultivars; and iv) onion bulb storage experiment. The bioactive effect of SC, FA and their combinations was identified by promoting changes in root growth of V. radiata. In pots, treatments containing FA, SC and combination promoted increase in fresh and dry leaf mass. The foliar application of FA, SC and combination promoted an increase in field bulb productivity, reduced mass loss in stored bulbs and increased carbohydrate, amino acid and protein contents in onion bulbs.

Conversion to organic farming: a dynamic opportunity for Pakistani smallholders of fresh fruit / Conversão para a agricultura orgânica: uma oportunidade dinâmica para pequenos produtores de frutas frescas do Paquistão

ABSTRACT: Exporting the organic fresh fruit (FF) to Europe and America could be regarded as great opportunity for smallholders and suppliers of Gilgit Baltistan, Pakistan. Yet, the global organic farmland and the number of organic producers are continued to grow. To date, little is known about the behavior of Pakistani farmers towards organic fresh fruit production. This study examined the factors that influence the decision-making of fresh fruit smallholders concerning the conversion to organic farming (COF). This study uses Ajzen's theory of planned behavior (TPB) to predict the behavior of Pakistani smallholders of fresh fruit. Path analysis examined the utility of the extended version of the TPB model to anticipate 277 small-scale farmers' behavioral intentions towards the adoption of organic farming (AOF) and their prospect of converting their farm to organic produce within the next three years. The present study reported that the smallholders' attitude (ATT), subjective norms (SN), perceived behavior control (PBC), and farmer's group participation (FGP) were positively correlated with farmer's intention to adopt organic farming, while group participation of farmers has significant correlation with their behavior regarding production of organic fruits. The present study justifies using the model of farmers' group participation in policies that deliberately cheer up smallholders of fresh fruit to adopt organic farming, to raise farm incomes and to alleviate poverty.

RESUMO: Exportar a fruta fresca orgânica (FF) para a Europa e América pode ser considerada uma grande oportunidade para pequenos proprietários e fornecedores de Gilgit Baltistan, Paquistão. No entanto, as terras agrícolas orgânicas globais e o número de produtores orgânicos continuam a crescer. Até o momento, pouco se sabe sobre o comportamento dos agricultores paquistaneses em relação à produção de frutas frescas orgânicas. O objetivo deste estudo, portanto, foi examinar e determinar os fatores que influenciam a tomada de decisão dos pequenos produtores de frutas frescas sobre a conversão para a agricultura orgânica (COF). Este estudo usa a teoria do comportamento planejado de Ajzen (TPB) para prever o comportamento dos pequenos produtores de frutas frescas do Paquistão. A análise de caminho examinou a utilidade da versão estendida do modelo TPB para antecipar as intenções comportamentais de 277 agricultores de pequena escala em relação à adoção da agricultura orgânica (AOF) e sua perspectiva de converter sua fazenda em produtos orgânicos nos próximos três anos. O presente estudo descobriu que a atitude dos pequenos proprietários (ATT), as normas subjetivas (SN), o controle do comportamento percebido (PBC) e a participação do grupo de agricultores (FGP) foram positivamente correlacionadas com a intenção do agricultor de adotar a agricultura orgânica, enquanto a participação do grupo de agricultores correlação significativa com seu comportamento em relação à produção de frutas orgânicas. O presente estudo justifica o uso do modelo de participação de grupos de agricultores em políticas que encorajam deliberadamente os pequenos produtores de frutas frescas a adotar a agricultura orgânica, para aumentar a renda agrícola e diminuir a pobreza.

Productivity and profitability assessment of organically grown vegetables embedded in rice based cropping sequences in Sikkim Himalayas, North East India

Aim: The objective of the present study was to identify economically viable, profitable and resource efficient vegetables embedded rice-based cropping sequences under organic management for marginal and small farmers of Sikkim Himalayas, India.Methodology: Three-year fixed plot study was conducted to evaluate seven rice–based cropping sequences viz., rice–fallow (farmers’ practice), rice–fenugreek (leafy vegetable), rice–coriander (leaves), rice–radish, rice–broccoli, rice–potato and rice–vegetable pea were replicated four-times in a completely randomized block design. Results: Among the various rice – based cropping sequences, cultivation of rice–coriander (leaves) recorded higher production (67.3 kg ha-1 day-1), system productivity (24.6 t ha-1), relative economic efficiency (1040%) and net returns (376.1x103). However, rice-broccoli and rice–vegetable pea sequences recorded 8.6 and 4.4% higher B: C ratio, respectively, over the rice–coriander system. With regards to soil health, rice – vegetable pea cropping sequences resulted in maximum improvement in soil organic carbon (SOC) (1.26%), available soil N (415.2 kg ha-1), P (22.8 kg ha-1) and K (411.5 kg ha-1), soil microbial biomass carbon (SMBC) (344.7 µg MBC g-1 soil), dehydrogenase activity (DHA) (24.0 µg TPFg-1 soil h-1) and fluorescin di acetate (FDA) (38.8 µg FDAg-1 soil h-1) among the cropping sequences. Interpretation: Induction of vegetables in rice–fallow system under assured irrigation condition of Sikkim Himalayas, India not only enhances the farm productivity and profitability but also sustain the soil health on long term basis. Thus, rice-vegetable pea/coriander/broccoli based production systems under organic management hold great promises for sustaining livelihood of organic growers in Sikkim Himalayas over conventional rice– fallow system.

Effect of pigeon pea intercropping or shading with leucaena plants on the occurrence of the coffee leaf miner and on its predation by wasps in organic coffee plantings / Efeito da consorciação com feijão-guandu ou sombreamento com plantas de leucena na ocorrência do Bicho-mineiro e sua predação por vespas em lavouras de café orgânico

ABSTRACT: The infestation of coffee leaf miner and its predation by wasps were assessed in commercial organic coffee plantings shaded with leucaena or intercropped with pigeon pea. Plantings in northern Paraná were assessed every two weeks from June 2011 to December 2012. The percent of infested leaves, number of mines per leaf and the percent of predation by wasps (indicated by lacerations) were determined. Fewer coffee leaf miners and fewer mines per leaf were found in pigeon pea intercropped plantings (28.4% and 0.3, respectively) than in shaded plantings with leucaena (48.1% and 0.8, respectively). More predation by wasps was found in the shaded (27.2%) than in the intercropped (13.2%) plantings. Suggestions for new studies are presented along with suggestions for managing the leaf miner in coffee plantings.

Effects of Arbuscular Mycorrhizal Fungi and Soil Conditions on Crop Plant Growth

We investigated the effects on various crops of inoculation with species of arbuscular mycorrhizal fungi (AMF) in soils from different sources and selected AMF species suitable for domestic environment-friendly farming. Effects on plants varied with the AMF species used. In carrot, Scutellospora heterogama, Acaulospora longula, and Funneliformis mosseae had a positive effect on growth of the host, whereas AMF had only weak effects on the growth of red pepper and leek. AMF inoculation had positive effects on the growth of carrot and sorghum. The results of this study indicate the nature of the relationship between soil, plants, and AMF; this study therefore has important implications for the future use of AMF in environment-friendly agriculture.

Impact of sugarcane cultivation on the biological attributes of an oxisol in the brazilian savannah / Impacto do cultivo da cana-de-açúcar nos atributos biológicos em latossolo no cerrado brasileiro

Sugarcane is fundamental for the energy matrix in Brazil. The evaluation of biochemical attributes in different sugarcane production systems provides information on their environmental sustainability. Altogether, soil biochemical attributes are considered very sensitive indicators of changes in soil properties and of alterations caused by soil management and land-use systems. The aim of this work was to study the effect of organic and conventional sugarcane cultivation systems on microbial soil properties. Changes in carbon (C) and nitrogen (N) microbial and microbial activity were evaluated in a Cerrado Oxisol in the state of Goiás, Brazil, cultivated with sugarcane in three different production systems: organic (Organic Cane - OC), conventional with burning (Burned Cane - BC), and conventional without burning (Raw Cane - RC). The native Cerrado (NC) and other cultivated pasture (PT) were used as references. The soil samples were collected during the dry and rainy seasons from two depths: 0-10 and 10-20 cm. The chronological order of the implementation of the land-use (NC, PT and sugarcane) and cultivation (RC, BC, OC) systems were: NC, PT, RC/BC, OC. The microbial biomass C (CSMB), microbial biomass N (NSMB), basal respiration (Br), metabolic quotient (qCO2) and the CSMB/Corg, NSMB/Ntotal and CSMB/NSMB ratios were determined. The different land-use and cultivation systems influenced microbial biomass and activity. The replacement of conventional tillage for organic system recovered CSMB and NSMB levels and improved recycling of nutrients in the microbial biomass (NSMB/Ntotal). The conventional tillage system with burning (BC) was less efficient in use of energy and carbon (high qCO2), resulting in a loss of C-CO2 to the atmosphere.

A cana-de-açúcar é de suma importância na matriz energética brasileira. A avaliação dos atributos bioquímicos do solo nos diferentes sistemas de produção da cana-de-açúcar fornece informações sobre a sustentabilidade ambiental destes sistemas de produção. Os atributos bioquímicos do solo são considerados indicadores muito sensíveis às alterações causadas nas propriedades do solo, em função do manejo nos diferentes sistemas de produção agrícola. O objetivo deste trabalho foi estudar o efeito do cultivo de cana-de-açúcar em sistema orgânico e convencional nas propriedades microbiológicas do solo. As alterações no carbono (C) e nitrogênio (N) microbiano e na atividade microbiana foram avaliadas em um Latossolo Vermelho sob Cerrado no estado de Goiás, Brasil, cultivado com cana-de-açúcar em três diferentes sistemas de produção: cultivo orgânico (CO), convencional com queima (CQ) e cultivo convencional sem queima da palhada e cana crua (CC). Uma área de cerrado nativo (CN) e outra cultivada com pastagem (PT) foram usadas como referências. As amostras de solo foram coletadas em duas épocas: seca e chuvosa; e em duas profundidades: 0-10 cm e 10-20 cm. A ordem cronológica de implementação do uso da terra foram: CN, PT e cana-de-açúcar; os sistemas de cultivo foram: CN, PT, CC/CQ, OC. O carbono da biomassa microbiana do solo (CBMS), nitrogênio da biomassa microbiana do solo (NBMS), respiração basal (Rb), quociente metabólico (qCO2) e as razões CBMS/Corg e NBMS/NTotal foram determinados. Os diferentes sistemas de produção da cana-de-açúcar alteraram a biomassa e a atividade microbiana. A substituição do sistema de cultivo convencional pelo sistema de cultivo orgânico recuperou os teores de CBMS e NBMS e melhorou a reciclagem de nutrientes na biomassa microbiana (NBMS/NTotal). O sistema de cultivo convencional com queima (CQ) foi o menos eficiente na utilização do carbono como energia (alto qCO2), resultando em perdas de C-CO2 para a atmosfera.

Manejo de parasitoses em sistema orgânico de produção de leite / Parasites management in dairy organic system

Os sistemas agropecuários de produção orgânica respondem às necessidades do mercado e às crescentes preocupações dos consumidores, relacionadas à qualidade dos alimentos, ao respeito ao meio ambiente e ao bem-estar dos animais. Em tais sistemas de produção animal, o emprego de produtos químicos de síntese é severamente limitado. Assim, a conversão de um sistema de produção animal convencional em sistema de produção orgânica é acompanhada de alterações relacionadas à intensidade e à diversidade de infestação/infecção dos animais por ecto e endoparasitos, tornando indispensável o emprego de medidas profiláticas. O presente trabalho tem como objetivo expor as principais questões relacionadas ao manejo de parasitoses em sistemas orgânicos de produção de leite, assim como suas perspectivas de controle...

Organic farming systems should meet the needs of markets as well as satisfy the emerging concerns of consumers about food quality, environmental issues and animal welfare. In such production systems, the use of synthetic chemical products is severely restricted. The conversion of conventional animal production systems into organic ones should encompass changes in the diversity and intensity of infection by parasites. Moreover, the use of prophylactic practices becomes imperative. The aim of this article is to set forth the main questions associated to parasite management in organic dairy production systems as well as their control perspectives...

Controle de plantas invasoras em cultivo orgânico e convencional de capim-limão (Cymbopogon citratus (DC) Stapf. ) / Weed control in organic and conventional crops of lemongrass

O cultivo orgânico é preconizado para o capim-limão (Cymbopogon citratus (DC) Stapf.) como planta medicinal promissora ao desenvolvimento de fármacos no Brasil. Objetivou-se avaliar técnicas de controle de plantas invasoras sobre componentes de produção de capim limão em cultivos orgânico e convencional. Dois experimentos foram instalados sob delineamento inteiramente casualizado, com quatro repetições, em esquema fatorial 2x2x3, considerando-se duas áreas (orgânico e convencional) e os tratamentos combinando cobertura morta (presente e ausente) e técnicas de controle de plantas invasoras (capina manual, roçada e nenhuma). Altura, perfilhamento, teor e rendimento total de óleo essencial de capim-limão no cultivo orgânico foram superiores ao convencional, mas a produtividade de biomassa aérea seca não diferiu entre ambos. A capina, com ou sem cobertura morta, favoreceu o rendimento de óleo no cultivo orgânico.

Organic farming is recommended for lemongrass as a promising medicinal plant for drug development in Brazil. The purpose of this paper was to evaluate the effect of the techniques to control weed on the plant height, tillering, biomass productivity, content and yield of the essential oil of lemon grass in organic and conventional crops. Two experiments were set in a completely randomized design with four replications, at a 2x2x3 factorial scheme, considering two areas (organic and conventional) and treatments combining mulching (present and absent) and weed control techniques (hoeing, skimming and none). Plant height, tillering, content and yield of the essential oil of lemongrass were better in the organic crop, but the biomass productivity did not differ between both areas. The biomass production was better in the conventional crop as to weed control, with or without mulching, and for organic crop under hoeing or skimming with mulching. Hoeing or skimming with no mulching improved the oil content in organic crops. Hoeing or skimming with mulching was better than any other weed control technique with no mulching, and hoeing was better than skimming, justifying its recommendation as a technique for this crop system.

Effect of Organic Farming on Spore Diversity of Arbuscular Mycorrhizal Fungi and Glomalin in Soil

In this study, eight soil samples were collected from organic and conventional farms in a central area of South Korea. Spore communities of arbuscular mycorrhizal fungi (AMF) and glomalin, a glycoprotein produced by AMF, were analyzed. Spores of Glomus clarum, G. etunicatum, G. mosseae, G. sp., Acaulospora longula, A. spinosa, Gigaspora margarita, and Paraglomus occultum were identified at the study sites, based on morphological and molecular characteristics. While Acaulospora longula was the most dominant species in soils at organic farms, Paraglomus occultum was the most dominant species in soils at conventional farms. Species diversity and species number in AMF communities found in soils from organic farms were significantly higher than in soils from conventional farms. Glomalin was also extracted from soil samples collected at organic and conventional farms and was analyzed using both Bradford and enzyme-linked immunosorbent assays. The glomalin content in soils from organic farms was significantly higher than in soils from conventional farms. These results indicate that agricultural practices significantly affect AMF abundance and community structure.

Effects of Organic Farming on Communities of Arbuscular Mycorrhizal Fungi

Red pepper (Capsicum annum L.) roots and soils representing different agricultural management practices such as conventional (CON), no-chemical (NOC), and organic farming systems (ORG) were collected from 32 farm field sites in Kyunggi, Korea to investigate the effects of these agricultural practices on arbuscular mycorrhizal (AM) symbiosis. ORG inoculum significantly increased plant growth compared to inoculum from CON and NOC. A community analysis of AM fungi (AMF) using morphological features of spores revealed that AMF spore abundance and species diversity were significantly higher in ORG than in CON. Additionally, a community analysis of AMF colonizing roots using a molecular technique revealed higher AMF diversity in ORG than in CON. These results suggest that agricultural practices significantly influence AM fungal community structure and mycorrhizal inoculum potential.
