Vermiculture and organic farming has attracted the attention on naturalists, ecologists and workers in applied sciences such as Agriculture, Pest Management, Horticulture, Sericulture etc., at global scenario. Agricultural chemicals increase tremendous pressure on agroecosystem. Increasing use of chemical fertilizers and pesticides lead to serious problems in agroecosystem such as air, water and soil pollution, pest resistance, pest resurgence, secondary pest out break, killing of beneficial and non target organisms, destruction of ecocycles and endemic soil fauna, drying of soil, etc. The use of biofertilizers, vermicompost, biological pest control technique will certainly add great relevance in solving the above problems. Therefore, in the present book, attempts have been made on Vermiculture and Vermicomposting, Biofertilizers and their Production and Production of Biological Pest Control Agents. Importance of biofertilizers, species diversity, applications and production technique for Rhizobium, Azotobacter, Azolla, Blue-green algae, Mycorrhizae, Azospirillum, Green manure, Organic composting have been described under the chapter Biofertilizers and their Production, while, under the chapter production of biological pest control agents, emphasis is given on the importance of biological pest control technique and mass production techniques of various BCA such as Trichogramma, Chilonus blackburni, Cryptolaemus montrouzieri and Crysoperla carnea. This book is need of modern agriculture and useful guide to naturalist, students, teachers, farmers, researchers and industrialist. Contents Chapter 1: Vermiculture and Vermicomposting; Chapter 2: Biofertilizers and their Production; Phosphate solubizing microorganisms, Rhizobium production, Azotobacter production, Azospirillum production, Blue green algae (BGA) production, Azolla production, Mycorrhiza production, Green manure, Organic matter and composting; Chapter 3: Production Techniques for Biological Pest Control Age
