Efficacy of Biological Soil Amendments and Biocontrol Agents for Sustainable Rice and Maize Production

摘要: Exploiting the agroecosystem services of soil microbes appears as a promising effective approach to alleviate negative impacts on systems and crop production. Lack organic matter (SOM) is prevalent feature degraded soils. Different biological amendments, such manure, compost, vermicompost, indigenous microbes, residues, are widely used in reclamation The amendments also furnish valuable source fertilizer for growing rice maize boost physicochemical parameters water holding capacity, moisture content, electrical conductivity, carbon population beneficial which directly correlates health fertility. However, efficiency applied based variety factors including composition characteristics, microflora, environmental conditions can accelerate initial lead self-sustaining primary productivity crops. On other hand, high cost chemical fertilizers, pesticides, agricultural inputs their harmful legacy have encouraged researchers explore use microbial-mediated play central role raising inhibition/suppression pathogenic below levels at they cause economic effects crops well environment. Biological control be achieved through one or more mechanisms, viz., antibiosis, competition nutrients and/space, induced resistance, plant growth promotion, rhizosphere colonization ability. Potent biocontrol agents Bacillus sp., Pseudomonas Tricoderma sp. prove very controlling soilborne diseases employing both antibiosis induction host resistance. Determination modes action obligatory provide higher level protection under particular condition that exists divergent agroecosystems. This chapter reviews an insight mechanisms emphasis amelioration with goal sustainable system.
