Abstract/ Executive Summary:

The experiment was conducted at the Bangladesh Rice Research Institute, Regional Station, Rajshahi during December 2004 to May 2005 to investigate the performance of organic fertilizers compared to inorganic fertilizers on modern rice and determine improvement in yield and profitability. A total of 13 treatments (T₁ to T₁₃) were used in the investigation where T₁ (BRRI recommended practice) was standard check and T₁₃ was without fertilizer (control). BRRIdhan29 was used in the experiment as high yielding long duration (160 days) variety. Grain yield, panicles per unit area, grains per panicle, 1000-grain weight were significantly affected by different treatments, however it had no effect on sterility percentage. The highest grain yield (7.46 t.ha^-1) was obtained in T₄ where 250 kg.ha^-1 Agro meal was applied with reduced amount of inorganic fertilizer. This was followed by T₈ (7.42 t.ha^-1), T₂ (7.37 t.ha^-1) and T₁₂ (7.20 t.ha^-1) that were statistically similar with T₄. On the contrary, the lowest grain yield (3.58 t.ha^-1) was found in absolute control treatment (T₁₃). In general, grain yield was higher in the treatments where inorganic fertilizers were applied along with organic fertilizers. In fact, there was no significant difference among the treatments used only organic fertilizers with no-fertilizer treatments. The highest yield increase (11.5 %) was recorded in treatment T₄ followed by T₈ (10.8 %) and T₂ (10.1 %) over the researcher’s practice (T₁). Grain yield in the treatments T₁₃, T₃, T₅, T₇, T₉ and T₁₁ (where only organic fertilizers applied) was not increased compared to T₁. Net profit was found in most of the treatments where applied organic fertilizer along with inorganic fertilizers. The highest net profit was obtained in T₄ (Tk. 15,368) followed by T₈ (Tk. 12,554), T₂ (Tk. 12190) and T₆ (Tk. 10,420). The benefit cost ratio (BCR) followed the similar trend of net profit.

End Date: 00-05-2005

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To evaluate the organic fertilizers compared to chemical fertilizers
To identify the best nutrient management option for Boro rice.

Methodology:

The experiment was conducted at the Bangladesh Rice Research Institute, Regional Station, Rajshahi, during December 2004 to May 2005 in Boro season. The field was situated in High Gangetic River Floodplain under AEZ 11 having silty loam soil with pH 8.4, Organic matter 2.20 %, K 0.19 me/100 g soil, N 0.12 % and P, S, B & Zn were 1.00, 33.96, 0.39 & 3.60 microgram, respectively. A total of 13 treatments were used in this investigation where T₁ (researcher’s practice) was standard check and T13 was without fertilizer (control). The treatments were T₁ = Researcher's practice: N, P, K, S and Zn @ 124, 26, 60, 12 & k3.6g/ha; T₂ = Mustard cake 75 kg/ha + T₁; T₃ = Agro meal 250 kg/ha as basal; T₄= Agro meal 250 kg/ha + Urea 162 kg/ha + MOP 120 kg/ha + Gypsum 70 kg/ha; T5 = Agro meal plus 300 kg/ha as basal; T₆ = Agro meal plus 300 kg/ha + Urea 162 kg/ha + MOP 120 kg/ha + Gypsum 42 kg/ha; T₇ = Agro fertilizer (Organic) fertilizer 740 kg/ha as basal; T₈ = Agro fertilizer (Organic) fertilizer 740 kg/ha + Urea 162 kg/ha + TSP: 78 kg/ha + MOP 72 kg/ha + Gypsum 42 kg/ha; T₉ = Agro fertilizer (Organo-Inorganic) fertilizer 740 kg/ha as basal; T₁₀ = Agro fertilizer (Organo-Inorganic) fertilizer 740 kg/ha + + Urea 162 kg/ha + TSP 91 kg/ha + MOP 84 kg/ha + Gypsum: 42 kg/ha; T₁₁ = Raj Joibo (Organic) fertilizer: 790 kg/ha as basal; T₁₂ = Raj Joibo (Organic) fertilizer 790 kg/ha + Urea 162 kg/ha + TSP 98 kg/ha + MOP 108 kg/ha + Gypsum 49 kg/ha and T₁₃ = No fertilizer. Randomized Complete Block Design with three replications was followed. A high yielding long duration (160 days) variety BRRIdhan29 was used in the experiment. The unit plot size was 3 m x 5 m. Fifty-day old seedlings were transplanted with 20 cm X 20 cm spacing on 02 January 2005. Fertilizers were applied as per treatments. Standard agronomic and pest management practices were used equally for all the treatments as and when required. Grain yield was taken from 6-m² area. Grain yield was adjusted at 14% moisture. Yield components were recorded from 16 randomly selected hills in each plot (4 hills each from each of 4 corners of the plot). All data gathered in this experiment were analyzed by IRRIStat 7.2.

Achievement/Findings:

Agro fertilizer and mustard cake had responded positively in increasing grain yield in the treatments where organic fertilizers applied along with inorganic fertilizers. Higher yield was obtained in the treatments T4, T8, T2, and T6 over the BRRI recommended practice (T1). However, lower yield in T3, T5, T7, T9 and T11 where applied merely organic fertilizers which was at par with the control plot. It could be concluded that organic matter along with sufficient inorganic fertilizer would be required to attain higher yield.
