Abstract/ Executive Summary:

We did the experiments at Bangladesh Rice Research Institute (BRRI), Gazipur during Boro seasons of 2010 and 2011. Fresh (0-3-day-old droppings) and one-month decomposed poultry litter (DPL) was used at variable rates and in combination with chemical fertilizers and compared with absolute control. Plant height, panicles/m² and grains per panicle were found statistically similar among the sole and integrated use of PL with chemical fertilizer treatments. Excessive vegetative growth was observed when fresh poultry litter (FPL) was applied @ 6 t/ha or more. The highest grain yields were recorded when 5 t/ha FPL along with 38 kg/ha N was used in both the years but the highest grain yield was observed when DPL @ 3 t/ha along with 65-11 kg/ha NP was used. The average requirement of FPL and DPL irrespective of its rate, N and P variations, grain yield was about 5.88 t/ha with FPl and 5.91 t/ha with DPL. This implies that both FPL and DPL can be utilized successfully for growing rice in Bangladesh.

Keywords: Fresh and Decomposed poultry litter, Growth and Yield of boro rice

Location: Bangladesh Rice Research Institute (BRRI), Gazipur

Start Date: 00-11-2010

End Date: 00-03-2011

Program Area: Crop-Soil-Water Management

Commodity: Manures

Objectives:

To find out the effect of FPL and DPL on growth and yield of Boro rice.

Methodology:

We did the experiments at Bangladesh Rice Research Institute (BRRI), Gazipur during two subsequent Boro seasons 2010 and 2011. Fresh (0-3-day-old droppings) and one-month decomposed PL was used at different rates and in combination with chemical fertilizers and compared with absolute control. The treatments imposed were, FPL 7 t/ha (T₁); FPL 6 t/ha (T₂); FPL 5 t/ha (T₃); FPL 5 t/ha along with N 38 kg/ha (T₄); FPL 3.5 t/ha along with NP 64-3 kg/ha (T₅); FPL 2.5 t/ha along with NP 82-11 kg/ha (T₆); DPL 3 t/ha along with NP 64-15 kg/ha (T₇); DPL 3.5 t/ha along with NP 64-3 kg/ha (T₈); DPL 2.5 t/ha along with NP 82-11 kg/ha (T₉) and no fertilizer application (T₁₀). In the treatments of integrated use of PL and chemical fertilizer, the amount of NPK in PL were calculated and then N, P and K were adjusted as of soil test based (STB) fertilizer application. The treatments were assigned in a randomized complete block design with three replications. Unit plot size was 4 x 3 m. The FPL and DPL were used before final land preparation as per treatments and seedlings were transplanted after three days of PL application. Forty-day-old seedlings of BRRI dhan45 were transplanted on 04-01-2010 and 07.01.2011 at 20- 20-cm spacing. Urea was top dressed thrice at 20 days after transplanting (DAT), 35 DAT and 5 days before panicle initiation. Triple super phosphate, muriate of potash, gypsum and zinc fertilizers were applied as basal. Initially continuous standing water was maintained for about two weeks and then normal water management practices were followed. Weeds were controlled by applying pre-emergence Butachlor (Vachete 5G) herbicide followed by one hand weeding at 40 DAT. Insecticide was applied as and when necessary. Data on plant height, panicles/m², grains per panicle, sterility percentage; grain and straw yields were recorded. The collected data were analysed following Gomez and Gomez (1984) and means were compared at the 5% level of probability.

Achievement/Findings:

Thus, it concluded that both the fresh and one-month decomposed poultry litter can be used either in combination with fertilizers or alone for satisfactory grain yield of Boro rice.
