Abstract/ Executive Summary:

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from June to December 2014 with a view to finding out the effect of plant spacing and integrated nutrient management on the yield of Binadhan-14. The experiment consisted of three spacing viz., 25 cm × 15 cm, 20 cm × 20 cm and 20 cm × 15 cm and seven nutrient management viz., recommended dose of inorganic fertilizer @ 180-150-70-65-8 kg ha^-1 of Urea-TSP-MoP-Gypsum-ZnSO₄ respectively, cowdung @ 10 t ha^-1, poultry manure @ 5 t ha^-1, 50% recommended dose of inorganic fertilizer + cowdung @ 5 t ha^-1, 50% recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha^-1, 50% recommended dose of inorganic fertilizer + cowdung @ 10 t ha^-1, 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1. The experiment was laid out in a randomized complete block design with three replications. Crop characters, yield components and yield of Binadhan-14 were significantly influenced by spacing, integrated nutrient management and their interaction. The highest number of effective tillers hill^-1(6.81), 1000-grain weight (22.67 g) and grain yield (4.78 t ha^-1) were recorded at the spacing 20 cm × 15 cm while in case of integrated nutrient management, the highest number of grains panicle^-1 (64.47) was found with 50% recommended dose of inorganic fertilizer + cowdung @5 t ha^-1, on the other hand, 1000- grain weight (22.91g), and grain yield (5.02 t ha^-1) were found with 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1while the lowest values from poultry manure @ 5 t ha^-1. The highest grain (5.53 t ha^-1) and straw (6.23 t ha^-1) yields were found at the interaction of 20 cm × 15 cm spacing fertilized with 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1. It can be concluded that short duration Binadhan-14 can be transplanted at the 20 cm × 15 cm spacing fertilized with 50% recommended dose of inorganic fertilizer + poultry manure @5 t ha^-1to obtain maximum grain yield.

Objectives:

To evaluate effect of plant spacing and integrated nutrient management on the growth and yield of Binadhan-14.

Methodology:

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh with a view to finding out the effect of plant spacing and integrated nutrient management on the yield of Binadhan-14. Geographically the experimental field is located at 24.75° N latitude and 90.50° E longitude at an average height of 18m above the mean of sea level. The experimental site belongs to the Old Brahmaputra Floodplain (AEZ-9). The experiment consisted of three spacing viz. 25 cm × 15 cm, 20 cm × 20 cm and 20 cm × 15 cm and seven nutrient management viz., recommended dose of inorganic fertilizer @ 180-150- 70-65-8 kg ha^-1 of Urea-TSP-MoP-Gypsum-ZnSO₄ respectively, cowdung @ 10 t ha^-1, poultry manure @ 5 t ha^-1, 50% recommended inorganic fertilizer + cowdung @ 5 t ha^-1, 50% recommended dose of inorganic fertilizer + poultry manure @ 2.5 t ha^-1, 50% recommended dose of inorganic fertilizer + cowdung @ 10 t ha^-1, 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1. The experiment was laid out in a randomized complete block design with three replications. The land was first opened with a tractor driven plough, ploughing followed by laddering were done with a country plough and a ladder. Weeds and stubbles were removed from the field as much as possible after leveling. The lands were finally prepared and the plots were laid out on 16 July, 2014. Thirty five-day old seedlings were transplanted on 17 July, 2014 maintaining three different spacings as per experimental specification using 3-4 seedlings hill^-1. Organic and inorganic fertilizers were applied according to experimental treatments. Full dose of triple super phosphate (TSP), muriate of potash (MoP), gypsum, zinc sulphate, cowdung and poultry manure were applied at the final land preparation. Nitrogen fertilizer in the form of urea was applied as per treatment of the experiment in three equal splits at 10, 30 and 45 days after transplanting (DAT). The crop was harvested at full maturity. The date of harvesting was confirmed when 90% of the seed became golden yellow in color. Five hills (excluding border rows and central 1 m² area) were selected randomly from each unit plot and up- rooted for recording data on yield components. After sampling a harvest area of central l m x l m was selected from each unit plot and harvested on 12 October, 2014. The crop was threshed by pedal thrasher and the fresh weights of grain straw were recorded plot wise. The grains were cleaned and sun dried to a moisture content of 14%. Finally grain and straw yields plot^-1 were recorded and converted to t ha^-1. Data on different parameters were compiled and tabulated in proper form for statistical analysis. Analysis of variance was done with the help of computer package MSTAT. The mean differences among the treatments were tested with Duncan's Multiple Range Test (Gomez and Gomez, 1984).

Achievement/Findings:

The highest number of effective tillers hill^-1(6.81), 1000-grain weight (22.67 g) and grain yield (4.78 t ha^-1) were recorded at 20 cm × 15 cm spacing. In case of integrated nutrient management the highest number grains panicle^-1 (64.47) was found with 50% recommended dose of inorganic fertilizer + cowdung 5 t ha^-1 while 1000- grain weight (22.91g) and grain yield (5.02 t ha^-1) were found when fertilized with 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1. The highest grain (5.53 t ha^-1) and straw (6.23 t ha^-1) yields were found at the interaction of 20 cm × 15 cm spacing fertilized with 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1. Therefore, Binadhan-14 can be transplanted at the 20 cm × 15 cm spacing fertilized with 50% recommended dose of inorganic fertilizer + poultry manure @ 5 t ha^-1 appears as the promising combination to obtain maximum grain yield in Aman season.
