Abstract
Bio-fertilizer is low cost, renewable sources of plant nutrients which can supplement of chemical fertilizers. Excessive use of chemical fertilizers and pesticides has either reduces or eliminated such essential microbial populations from the agriculture soils. It has thus become necessary to produce such bio-fertilizers at commercial scale and add to the soil. In the present work the author has prepared three types of bio-fertilizers by using different waste materials. Firstly prepared biofertilizer by using kitchen waste, secondly by using biomass (such as rice husk, rice straw, bamboo leaves, soil, and water) and other types of bio-fertilizer is liquid, prepared by using biomass and Molasses. After preparation of above bio-fertilizers, they were used in different field crops such as ladies finger and study the growth and production of crops after an interval of every five day. Performance of crops under there biofertilizers was also studied.
