Abstract/ Executive Summary:

Proper planting methods are important for crop establishment and fertilizer has a beneficial effect on soil physical properties. Keeping this in view a study was carried out at biological science research field, Rajshahi University campus during June to October 2000 to evaluate the planting methods and different N fertilizer effect on yield and yield contributing characters of BRRI dhan39. Three planting methods and two N fertilizer materials with no fertilizer treatment using split plot block design with three replications. The results demonstrated that direct seedling line sowing and transplanting produced significantly higher yield components and grain yields. Grain and grain straw yields of BRRI dhan39 were increased due to different N fertilizer treatment and highest value was recorded with the application of pilled urea in the direct seedling line sowing and transplanting methods that of direct seedling broadcasting methods respectively. The harvest index and straw yield were also higher for the line sowing than broadcast sowing. Fertilizer helps to increase the plant height, straw dry matter, grain weight and fertile tiller number.

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To evaluate the planting methods and different N fertilizer effect on yield and yield contributing characters of BRRI dhan39.

Methodology:

Plant materials and experimental design - The research work was conducted in the Biological science research field, Rajshahi University campus during June to October 2000 to evaluate the planting methods and different N fertilizer effect on yield and yield component of BRRI Dhan 39. The main experimental field was 32.5m X 16m which was divided into 3 replication. Each replication includes 3 plots; in total there were 27 plots and land design were spilt plot design. The treatment randomly assigned to each unit plots. The selected rice variety BRRI dhan 39 was collected from BRRI Regional station, shampur, Rajshahi, Bangladesh. Planting methods - Three planting methods were B=Broadcasting direct seedling, L= Broadcasting line sowing and T =Transplanting were used as parameter to conduct this experiment. Fertilizer treatment - Fertilizer treatment were F₁ (Pilled Urea), F₂ (DAP + Guti Urea) and F_o = No Urea (Control). Fertilizer N rate were applied first in direct seedling methods (B+L) of 40 days after sowing seeds and transplanting methods first 10 days after transplant. Second and third time fertilizer applications were 55 and 70 days after sowing the seeds. The doses of fertilizer per plot were pilled urea 117.39gm, Diamonium phosphate 48gm, and Guti urea 97gm respectively. Management of agronomic characters - The agronomic characters were Plant height(PH), Straw dry matter(DM), Flag leaf Length (FLL), Flag leaf breath (FLB), Total tiller number/m², Fertile tiller number/m², Grain weight/m²(g), 1000-grain weight(g), Straw weight/m²(g). The data were analyzed statistically with Fisher’s analysis of variance technique at 5% probability level; treatments were compared using a protected LSD test.

Achievement/Findings:

The results indicated that BRRI dhan39 responded better to the T method rather than from B. But among the planting method T and L had similar response.
