Influence of Jeevamrutha and Panchagavya on Beneficial Soil Microbial Population and Yield of Organic Fieldbean (Dolichos lablab L.)

摘要

A study on influence of organic liquid manures, panchagavya and jeevamrutha on soil microbial population and yield of fieldbean {Dolichos lablab L.) was conducted at research and demonstration block of Research Institute on Organic Farming, Universityof Agricultural sciences, GKVK, Bengaluru. Twelve different treatments with three different levels of Jeevamrutha (0,500,1000 liters /ha) and Panchagavya (0,2.5,5 and 7.5%) were considered with fieldbean {Dolichos lablab L.) as a test crop. The soil samples from rhizosphere were analysed at initial and final stages of crop growth for different groups of micro-organisms by serial plate count method. Among different treatments tested, the treatment 12 (J1000 P7 50) recorded maximum population of generalbacteria, fungi andactinomycetes (Initial: 40.33X105 CFU/g, 20.33X104CFU/g, 15.33X103CFU/g and Final: 50.33X105 CFU/g, 32.33X104CFU/g, 20.33 X103 CFU/g), respectively compared to control (JP0). Significant difference in yield of fieldbean was observed with different levels of Jeevamrutha and Panchagavya at 7.5 per cent application. Higher yield of 1472.4 kg per ha was recorded with higher levels of Panchagavya and Jeevamrutha (7.5% and 1000 liter/ ha) application when compared to control treatment. Theresults indicated that the liquid manures i.e., Jeevamrutha and Panchagavya have supported the multiplication of different beneficial microbial population and yield of fieldbean crop.
