Abstract/ Executive Summary:

This study was conducted to evaluate the efficacy of different organic manure and inorganic fertilizer on the yield and yield attributes of Boro Rice (Oryza sativa L.). The experiment consisted of 8 treatments, T₀: Control, T₁: 100% N100P15K45S20 (Recommended dose), T₂: 50% NPKS + 5 t cowdung ha^-1, T₃: 70% NPKS + 3 t cowdung ha^-1, T₄: 50% NPKS + 4 t poultry manure ha^-1, T₅: 70% NPKS + 2.4 t poultry manure ha^-1, T₆: 50% NPKS + 5 t vermicompost ha^-1and T₇: 70% NPKS + 3 t vermicompost ha^-1. At 30, 50, 70, 90 DAT and at harvest stage the tallest plant (24.18, 31.34, 44.67, 67.05 and 89.00 cm) and the greatest number of total tiller per hill (5.43, 11.64, 21.01 and 17.90) at same DAT was recorded from T₅ and the lowest was observed from T₀ in every aspect. The maximum number of effective tillers per hill (13.52), the longest panicle (24.59 cm), maximum number of total grain per plant (97.45), the highest weight of 1000 seeds (21.80 g), the maximum grain yield (7.30 t ha^-1) and straw yield (7.64 t ha^-1) was recorded from T₅ treatment whereas the lowest number of effective tillers per hill (6.07) , the shortest panicle (16.45 cm) , the minimum total grain per plant (69.13) , the lowest weight of 1000 seeds (16.73 g), the lowest grain yield (2.06 t ha^-1) and straw yield (4.63 t ha^-1) was observed from T₀ treatment. Although the highest biological yield was recorded from T₅ treatment but statistically similar result were found from T₃, T₄ and T₇ treatments. The highest harvest index also recorded for T₅treatment. It was obvious that yield of rice can be increased substantially with the judicious application of organic manure with chemical fertilizer.

Location: Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh

Start Date: 00-12-2007

End Date: 00-04-2008

Program Area: Crop-Soil-Water Management

Commodity: Manures

Objectives:

To develop a suitable integrated dose of inorganic fertilizers and organic manures for Boro rice and
To observe the effects of different levels of inorganic fertilizers and organic manures on the yield as well as yield components of Boro rice.

Methodology:

The experiment was conducted in the Farm (23046'16.18” N latitude and 90022'36.54” E longitude) of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during December 2007 to April 2008 to study the efficacy of various organic manure and inorganic fertilizers on the yield and yield attributes of boro rice (BRRI dhan 29). The climate of the experimental area is characterized by high temperature, high humidity and medium rainfall during the kharif season (March-September) and a scanty rainfall associated with moderately low temperature in the rabi season (October-February). The land was first opened on 24 October, 2007 by a tractor and prepared thoroughly by ploughing and cross ploughing with a power tiller and country plough. Finally each plot was prepared by puddling. The experiment was laid out in a randomized complete block design (RCBD), with four blocks. Each block was divided into eight unit plots as treatments with raised bunds around. The unit plot size was 2 m x 2 m (4 m²). The distance maintained between two blocks and two plots were 1.0 m and 0.5 m, respectively. Before land preparation, initial composite soil sample were collected at 0-15 cm depth from different spots and prepared for physical and chemical analysis. The experimental site is fairly level, well drained and belongs to Deep Red Brown Terrace Soil under Madhupur Tract (AEZ- 28). The physical and chemical characteristics of initial soils are given

Achievement/Findings:

Combined application of 70% NPKS and 2.4 t poultry manure ha^-1 produced the highest number of effective tillers, largest panicles, the maximum number to total grain per plant, highest weight of 1000-grain as well as grain yield (7.64 tha^-1) and straw yield(7.30 tha^-1). Therefore, it can be recommended that 70% NPKS and 2.4 t poultry manure ha^-1 combination is best for the yield of boro rice BRRI dhan 29.
