Abstract/ Executive Summary:

Results indicated that application of different packages of fertilizers increased grain and straw yields of rice differed significantly over absolute control treatment. The grain and straw yields of T. Aman rice (cv. Binadhan-4) during 2010 ranged from 1.90-5.20 and 3.00-6.83 t/ha, respectively. The highest grain yield of 5.20 t/ha was recorded in treatment T₈ (N₉₀P₁₂K₃₆S₁₀ kg/ha) which was statistically identical with T₉, T₇, T₆, and T₃. On the other hand, treatment T₁ which received no fertilizer produced lowest yields of 1.90 t/ha. The grain and straw yields of Boro rice (cv. Binadhan-5) during 2011 ranged from 2.10– 5.95 and 3.35–7.00 t/ha, respectively. The highest grain yield of 5.95 t/ha was recorded in treatment T₈ (N₁₄₀, P₂₀, K₈₀, S₂₀, Zn₃ and B₂ kg/ha with 2 t/ha press mud based on IPNS) which was statistically identical with with T₉, T₇, T6, and T₃, respectively. On the other hand, treatment T₁ which received no fertilizer produced lowest yields of 2.10 t/ha. Like grain yields, the straw yields also differed significantly due to treatments.

Keywords: Rice yield, Fertilizer, Organic matter

Location: BINA Farm, Mymensingh

Start Date: 10-01-2010

End Date: 30-10-2011

Program Area: Crop-Soil-Water Management

Commodity: Manures

Objectives:

To determine the suitability of different sources of organic materials for integrated use with chemical fertilizers for increasing crop productivity and maintain soil fertility.

Methodology:

The experiment was initiated during 2010-11 at BINA farm, Mymensingh using Rice-Fallow-Rice cropping pattern to determine the suitability of different sources of organic materials for integrated use with chemical fertilizers for increasing crop productivity and maintain soil fertility. The initial soil properties and nutrient content of different organic materials used at different experiments were cowdung, press mud, tobacco dust, rice straw and poultry manure. There were nine treatment combinations. The experiment was laid out in a randomized complete block design with three replications. Organic materials were applied to each crop before rice transplanting.

Achievement/Findings:

Incorporation of press mud and/or tobacco dust @ 2 t/ha along with recommended fertilizer dose for MYG recorded identical grain yield of boro and T. aman rice compared to fertilizers applied for HYG. In case of HYG, IPNS based recommended fertilizers with press mud or tobacco dust @ 2 t/ha performed better compared to those with full dose of chemical fertilizers.
