Abstract
Establishment of huge number of biogas plant in the recent years in Bangladesh creates a burden to disposal of bioslurry. An attempt was undertaken to explore the usability of bioslurry in agricultural crop production under potato-rice system as well as to reduce bioslurry induced pollution. The experiment involved a sole chemical fertilizer treatment, four treatments based on integrated plant nutrition system with 5 t ha-1 cowdung and cowdung bioslurry and 3 t ha1 poultry manure and poultry manure bioslurry, and a control. The potato crops received manures or slurries, and its residual effect was evaluated on the succeeding T.Aman crop. Poultry manure bioslurry, poultry manure, cowdung bioslurry and cowdung gave 22.5, 20.0, 9.9 and 2.9 % increase in total system productivity, respectively over sole chemical fertilizer treatment. Bioslurries had higher contribution compared to their respective original manure. Bioslurry was found very useful as manure for crop production.Res. Agric., Livest. Fish.2(1): 27-33, April 2015

Stem length across the treatments ranged from 15.5 - 46.2 cm in 2011 and 21.8 - 52.5 cm in 2012.The tallest plants were found in Poultry manure (PM) bioslurry + integrated plant nutrition system (IPNS) basis chemical fertilizer (T5) treatment in 2011
In 2012, the tallest plants were recorded with the T4 treatment (PM + IPNS basis chemical fertilizer), it was statistically similar with T6 treatment
Summary
Establishment of huge number of biogas plant in the recent years in Bangladesh creates a burden to disposal of bioslurry. To cite this article: MA Haque, M Jahiruddin, MM Rahman and MA Saleque. In both years higher number of tubers was produced by the T3 treatment (CD-bioslurry + IPNS basis chemical fertilizer) compared to the original manure (T2).
