At present, a large amount of biogas slurry (BGS) is produced in India. Discharging them unprocessed will lead to environmental pollution, while disposing of them as sewage will cost a great deal because of its large pollution load. Moreover, replacing chemical fertilizers with biogas slurry can not only achieve resource utilization of biogas slurry, but also reduce the amount of chemical fertilizer. So resource utilization of biogas slurry seems to be potential and necessary. Therefore, in the present investigation we had made an effort to examine the effectiveness of biogas slurry as a nitrogen source for the production of baby corn. Results showed that 50% BGS along with 50% chemical fertilizer gave 20% more yield in terms of cob as well as biomass. Thus a farmer could save the 50% inorganic fertilizer and generate 20% additional revenue with the application of biogas slurry. Results showed that 50% BGS along with 50% chemical fertilizer showed higher plant height, leaf area, number of leaves and harvest index over control. Based on these results, it may be concluded that the combination of 50% biogas slurry with 50% chemical fertilizer (Urea) will improve the production of baby corn in environmentally sustainable manner.
