Effect of Compost Derived From Decomposed Fruit Wastes by EffectiveMicroorganism (EM) Technology on Plant Growth Parameters of Vignamungo

S. Karthick Raja Namasivayam, R.S. Arvind Bharani

In the present study, the plant growth promoting effect of compost derived from decomposed fruit wastes by
commercial formulation of Effective Microorganisms (EM-1) on plant growth parameters of Vigna mungo discussed. Effective Microorganisms (EM), a culture of co-existing beneficial micro organisms predominantly consisting of lactic acid bacteria, photosynthetic bacteria, yeast, fermenting fungi and actinomycetes that are claimed to enhance the decomposition of organic matter which in turn improves the soil fertility. In the present study ,the fruit wastes were effectively decomposed by applied effective microorganisms with complete reduction of volume of wastes, development of pleasant odour and formation of finely dispersed nutritious compost with 672.0, 708.0, 2927.0, 13.02 mg/kg and 35.1% of total nitrogen, phosphorous, potassium , humic acid and organic carbon. The plant growth parameters such as shoot length, leaf surface area, and total chlorophyll, height of the plant, total leaves and branches emerged in the plant, total foliage density/plant was increased in compost treated plants and distinct reduction in pest infestation and disease spots were recorded. As in plant growth parameters, compost treated plot reveals maximum phyllosphere, soil heterotrophic microbial population and soil nutrients via total nitrogen, phosphorous, potassium, organic carbon and humic acid. Total yield and cost benefit ratio was also increased in
compost treated plots.
