Integrated management of diluted distillery effluent and fly ash as a potential biofertiliser: a case study on the vegetative growth and chlorophyll content of the marigold plant, Tagetes patula

Distillery effluent as a liquid fertilizer: a win–win option for sustainable agriculture

“…Email: onlinekanchan1@gmail.com zero discharge into the surface water body from December 2005 and distillery units had to opt from any one of the three options, that is, ferti-irrigation, bio-composting and incineration. [3] Most of the distillery units in India have opted for ferti-irrigation. In ferti-irrigation, the yield of wheat (Tritium aestivum) increased by 33% [1] as compared to the control using Di-ammonium phosphate (DAP) and urea suggesting that the diluted distillery effluent is capable of replacing the application of chemical fertilizer when used under controlled conditions without any adverse effect on the soil and ground water quality.…”

[3] After the introduction of chemical fertilizer in the last century, farmers were happy of getting increased yield in agriculture and brought green revolution in 1960s with a substantial increase in National average yield of food grains. [4] In subsequent years, the application of high doses of nitrogen, phosphorus and potassium, high yielding varieties and excessive irrigation in certain cases have added to the problems of salinity, alkalinity, etc.…”

“…The beneficial effects of post-methanated diluted effluent post-methanated distillery effluent (PDME) have also been reported. [3,[8][9][10][11][12][13][14][15] As a matter of fact, fertiirrigation evoked a better ecological approach in agriculture at Mokamah Tal in Bihar (25°26.6 N 85°58.8 E), India, which is a water-deficient area with alluvial soil. Due to ferti-irrigation, the farmers are not only getting free water but also high content of macronutrients present in diluted PDME emanating from the distillery unit.…”

“…Earlier, the farmers were growing only one crop but due to ferti-irrigation, they are now growing two crops. [3] In the present study, mustard plant (Brassica compestris) was selected to study the effectiveness of diluted PDME on the vegetative growth of the plant as well as yield of the mustard seeds. Mustard seed is a good alternative cash crop to traditional grains, in India.…”
