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. |
