Description In order to find the ways and means of utilizing brewery wastewater for the
production of crops requiring large quantities of nutrients and water and to study the
response of brewable crops to brewery wastewater irrigation in cereal-cereal cropping
system. Field experiments were conducted on sandy loam soils at the premises of M/s.
United Breweries Ltd., Nelamangala and Agronomy field unit, ZARS, GKVK,
Bengaluru, located in Southern Dry Zone of Karnataka from 2009 to 2011. The
experiments were laid out in RCBD with first two experiments in maize-paddy and
paddy-barley sequence comprising nine treatments and three replications. Out of which
the best two treatments were selected and gypsum was included as an amendment with
four replications in the experiments three and four.
Results revealed that application of 150% recommended N through treated
brewery wastewater as 50% basal and 50% in three irrigations (T8) recorded significantly
higher grain yield of maize (39.6 q ha-1), growth parameters, yield components, quality,
nutrients uptake, soil available nutrients, soil microbial population and B:C ratio (2.47) as
compared to RDF with freshwater. Subsequently, residual and cumulative effect of the
same treatment recorded higher grain yield of paddy (21.3 & 43.8 q ha-1, respectively),
growth parameters, yield components, quality, nutrients uptake, soil available nutrients,
soil microbial population and B:C ratio (2.26 & 2.20, respectively) as compared to RDF
along with freshwater in maize-paddy sequence. Similar trend was noticed in paddybarley
cropping sequence.
Further, application 150% recommended N through treated brewery wastewater
as 50% basal and 50% in three irrigations with gypsum recorded higher grain yield of
maize (50.3 q ha-1), growth parameters, yield components, quality, nutrients uptake, soil
available nutrients, soil microbial population and B:C ratio (3.06) as compared to RDF.
Residual and cumulative effect of the same treatment recorded higher grain yield of
paddy (19.0 & 43.5 q ha-1, respectively), growth parameters, yield components, quality,
nutrients uptake, soil available nutrients, soil microbial population and B:C ratio (2.00 &
2.16, respectively) as compared to RDF in maize-paddy sequence. Similar trend was
noticed in paddy-barley cropping sequence.
