Abstract/ Executive Summary:

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 ha ^–1 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 contributi on compared to their respective original manure. Bioslurry was found very useful as manure for crop production.

Commodity: Manures, Potato, Rice

Objectives:

To investigate the usability of bioslurry as manure in the potato-rice cropping system.

Methodology:

The experiment was carried out during 2011 and 2012 at Soil Science Field Laboratory of Bangladesh Agricultural University farm, Mymensingh. The BAU farm soil belongs to ‘Sonatala’ soil series an Inceptisol under the AEZ 9 (Old Brahmaputra Floodplain).The silty clay loam soil had the following properties at 0–15 cm depth: sand 96 g kg ^-1 , silt 700 g kg^-1 , clay 204 g kg ^-1 , 6.4 pH, 2.13% organic matter, 1.1 mg g ^-1 total N, 5.00 mg kg^-1 available P (Olsen), 0.11 cmol kg ^-1 exchangeable K, 12.0 mg kg ^-1 available S, 0.65 mg kg ^-1 available Zn and 0.24 mg kg ^-1 available B contents. The experiment was laid out in a completely randomized block design with three replications, each plot size being 4 × 5 m and was separated by bunds. There were six treatments, namely recommended rate of nutrients from chemical fertilizers (T₁ ), and the next four treatments on integrated plant nutrition system (IPNS) basis i.e. recommended rate of nutrients from chemical fertilizer adjusted from manures - cowdung (T₂), cowdung bioslurry (T₃ ), poultry manure (T₄ ) and poultry manure bioslurry (T₅ ). The control treatment (T₆ ) received no fertilizer or manure. When N, P, K and S we re supplied from organic and inorganic sources based on IPNS basis; the amount of all nutrients was equal for all the treatments except T₆. The rate of manure application was 5 t ha^-1 for cowdung and cowdung bioslurry and 3 t ha^-1 for poultry manure and poultry manure bioslurry. The treatments were tested on potato-rice cropping system in two consecutive years. In each crop cycle, manure was applied to the first crop (potato) and their residual effect was evaluated on the succeeding T. Aman rice. The rate of fertilizer for potato was 135, 25, 95 and 12 kg ha^-1 of N, P, K & S, respectively for T₁ - T₆ . The T. Aman rice received equal amounts of N, P, K & S as chemical fertilizers at a rate of 75, 8, 30, 8 kg ha ^-1 , respectively. A blanket dose of Zn and B @ 2 and 1.5 kg ha ^-1, respectively were applied in all plots of potato crops. Basal application of P, K, S, Zn and B, and treatment wise manures were made dur ing final land preparation. Nitrogen was top dressed at 3 equal splits on final land preparation, 20 and 40 days after planting for potato and on 10, 25 and 45 days after transplanting for T. Aman rice. The potato tubers were planted maintaining spacing of 20×50 cm. For T. Aman rice 25 days old 3-4 seedlings comprising a hill were transplanted in rows maintaining 20×20 cm spacing. The potato tubers were planted on 24 and 23 November of 2010 and 2011 and T. Aman rice seedlings were transplanted on 27 and 29 July of 2011 and 2012, respectively. The crop varieties were Diamant for potato and BINA dhan7 for T. Aman rice. Two weeding cum earthing-up followed by irrigation was made in potato whereas T. Aman rice was grown on rain-fed condition. All crop protection measures were taken to prevent insect and disease attacks. Yields of tuber/grain and stover/straw of each crop were recorded after harvest of a 6 m² area from each plot at physiological maturity. Observation was made in terms of yield and yield components. Total system productivity was calculated through addition of potato yield and potato equivalent rice yield (PERY). Data recorded on crop characters were subjected to statistical analysis through computer based statistical program Mstat-C following the basic principles, as outlined by Gomez and Gomez (1984).

Achievement/Findings:

Poultry manure bioslurry or cowdung bioslurry gave greater amount of tuber/grain and stover/straw yield compared to their respective original state. Poultry manure source produce significantly greater yield than cowdung.
