Abstract/ Executive Summary:

Organic matter in rice soil in Bangladesh declining day by day and it is only around 1%. It is might be due to scarcity of organic manure to be applied in rice field. On the other hand, use of chemical fertilizers increasing along with intensive cropping significantly that degrading the soil properties. Now a days, poultry industry increased in large that could be the alternative source of organic manure in rice field. Therefore, the trials conducted at farmers field during November 2011 to May 2012 to validate the effect of poultry manure to increase yield. Growth duration of BRRI dhan50 in poultry manure applied and P applied plots were same for a particular location but some variations were found in different locations. Grain yield in poultry manure applied and P applied plots were very similar. The highest grain yield was found in Kapasia for its fertile land under single Boro rice area. Farmers observed that full dose of P fertilizer could be substituted by the application of poultry manure. Total 302 farmers showed their interest to apply poultry manure in their rice field in next season.

Start Date: 00-11-2011

End Date: 00-05-2012

Program Area: Crop-Soil-Water Management

Commodity: Manures, Rice

Objectives:

To validate and demonstrate the performances of poultry manure in rice field
To investigate effect of poultry manure on yield of rice.

Methodology:

Eight demonstrations on use of poultry manure in rice cultivation were conducted at 8 upazilas during Boro 2012. BRRI dhan50 were used for those trials. The plot size was 1 bigha for each of poultry manure and TSP. Thirty days decomposed poultry manure was applied @ 1.5 t/ha in one bigha per variety and recommended amount of TSP @120 kg/ha was applied in another one bigha to demonstrate the benefits of using poultry manure. Other management practices were same for 253 plots. Data on growth duration, grain yield, farmers' opinion and number of interested farmers were recorded.

Achievement/Findings:

Poultry farming is very common in Bangladesh. Due to poultry farming huge amount of poultry manure are available in our country which are the good source of phosphorus. There is a scope of utilizing this poultry manure in rice cultivation for supplying phosphorus. Judicious application of poultry manure may save a lot of foreign exchange that is used for importing chemical P fertilizers as well as help to improve the environmental pollution.
