Abstract/ Executive Summary:

A field experiment was carried out at Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka during the period from December 2007 to May 2008 to study the growth and yield of Boro rice BRRI dhan29 as influenced by N application and seedling types. The experiment was conducted with two levels of treatments viz. A. N application : No nitrogen (control) (N₀), 2 splits at ½ at active tillering stage + ½ at panicle initiation stage (N₁), 3 splits at 1/3 at 15 DAT + 1/3 at active tillering stage + 1/3 at panicle initiation stage (N₂), 3 splits at 1/3 at 15 DAT + 1/3 at active tillering stage + 1/3 at panicle initiation stage+ additional 10 kg N ha^-1 at flowering stage (N₃) and Urea Super Granules (N₄) and B. Seedling types: normal seedling as produced using farmers’ practices (S₁), seedling produced following BRRI recommendation (S₂) and robust seedling from modified mat nursery (S₃). The experiment was laid out in a split-plot design with 3 replications. The experimental result showed that N application had a significant effect on the studied parameters like plant height, number of tillers hill^-1, dry matter weight plant^-1, number of effective tillers hill^-1, number of non-effective tillers hill^-1, total grains panicle^-1, filled grains panicle^-1, unfilled grains panicle^-1, 1000-grains weight, grain yield, biological yield and harvest index. The highest grain yield (7.27 t ha^-1) was obtained from the Urea Super Granules (N₄) and control (N₀) gave the lowest grain yield (3.02 t ha^-1). Seedling types also significantly influenced all the growth and yield attributes. The highest grain yield (6.27 t ha^-1) was obtained from a robust seedling from modified mat nursery and the lowest grain yield (5.10 t ha^-1) was recorded from normal seedling as produced using farmers’ practices (S₁). The combined effect of N application and seedling types had also a significant effect on growth, yield attributes and yield. The interaction of Super Granule Urea (N₄) with robust seedling from modified mat nursery (S₃) gave the highest grain yield (7.84 t ha^-1).

Keywords: Rice, Nitrogen, Rice, Seedling types ,

Location: Sher-e-Bangla Agricultural University, Dhaka-1207

Start Date: 15-12-2007

End Date: 15-05-2008

Program Area: Crop-Soil-Water Management

Commodity: Rice, Fertilizer

Objectives:

To study the growth and yield of Boro rice BRRI dhan29 as influenced by N application and seedling types.

Methodology:

Treatments

The experiment considered two factors.

Factor A: N application -5

i. N₀= No nitrogen (control)

ii. N₁= 2 splits (½ at active tillering stage + ½ at panicle initiation stage)

N₂= 3 splits ( 1/3 at 15 DAT + 1/3 at active tillering stage + 1/3 at panicle initiation stage)
N₃= 3 splits ( 1/3 at 15 DAT + 1/3 at active tillering stage + 1/3 at panicle initiation stage) + additional 10 kg N ha^-1 at flowering stage
N₄= Urea Super Granules (Guti urea)

Factor B: Seedling types - 3

i. S₁= Normal seedling (produced following farmers’ practices)

ii. S₂= Seedling produced as recommended by BRRI

iii. S₃= Robust seedling from modified mat nursery

Experimental design and layout

The experiment was laid out following Split Plot Design with three replications. The layout of the experiment was prepared as per treatment, where nitrogen was assigned in the main plot and seedling type in the sub-plots. There were 15 plots, each measuring 4m × 2.5 m in each block. The total number of plots were 45. The distances between plot to plot and replication to replication were .75 m and 1 m, respectively.

Achievement/Findings:

Grain yield varied significantly due to the application of N splitting. The highest grain yield (7.27 t ha^-1) was found from N₄(Urea Super Granules) and the lowest (3.02 t ha^-1) was observed from N₀(No nitrogen). S₃ (Robust seedling from modified mat nursery) gave the highest grain yield (6.27 t ha^-1) whereas S₁ (normal seedling produced following farmer’s practices) produced the lowest grain yield (5.10 t ha^-1). The maximum grain yield (7.84 t ha^-1) was found from N₄S₃ (Urea Super Granules × Robust seedling from modified mat nursery) and the lowest (2.66 t ha^-1) was recorded from N₀S₁(No nitrogen × normal seedling produced following farmers’ practices). The highest straw yield (7.73 t ha^-1) and biological yield (15.00 t ha^-1) were obtained from N₄(Urea Super Granules). The lowest straw yield (4.52 t ha^-1) and biological yield (7.54 t ha^-1) were observed from N₀(No nitrogen). The maximum straw yield (6.92 t ha^-1) and biological yield (13.19 t ha^-1) were recorded from S₃ (Robust seedling from modified mat nursery) whereas the lowest straw (6.22 t ha^-1) and biological yield (11.32 t ha^-1) was found from S₁(normal seedling produced following farmer’s practices). Interaction N₄S₃ (Urea Super Granules × Robust seedling from modified mat nursery) produced the highest straw (8.09 t ha^-1) and biological yield (15.93 t ha^-1) and N₀S₁(No nitrogen × normal seedling produced following farmers’ practices) gave the lowest straw (4.31 t ha^-1) and biological yield (6.97 t ha^-1) . The seedling types, N splitting and the interaction of N splitting with seedling types showed a significant variation on harvest index. The maximum harvest index (48.43%) was obtained from N₄(Urea Super Granules) and the minimum (39.92%) was observed from N₀(No nitrogen). The highest harvest index (46.93%) was found from S₃(Robust seedling from modified mat nursery) and the lowest harvest index (44.26%) was observed from S₁(normal seedling produced following farmers’ practices). The highest harvest index (49.21%) was found from the interaction N₄S₃(Urea Super Granules × Robust seedling from modified mat nursery) and the lowest harvest index (38.16%) was recorded from N₀S₁ (No nitrogen × normal seedling produced following farmers’ practices).
