Abstract/ Executive Summary:

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during November 2016 to April 2017 to study the impact of nutrient management on the performance of aromatic fine rice in Boro season. The experiment comprised three varieties viz., BRRI dhan50, Basmati and BRRI dhan63; and seven nutrient managements viz.,poultry manure @ 5 t ha^-1, recommended dose of chemical fertilizers (i.e. 250, 126, 120, 100 and 10 kg N-P-K-S-Zn, respectively ha^-1), 25% less than recommended dose of chemical fertilizer + poultry manure @ 2.5 t ha^-1, 50% less than recommended dose of chemical fertilizer + poultry manure @ 5 t ha^-1, vermicompost @ 10 t ha^-1, 25% less than recommended dose of chemical fertilizer + vermicompost 5 t ha^-1, 50% less than recommended dose of chemical fertilizer + vermicompost @ 10 t ha^-1. The experiment was laid out in a randomized complete block design with three replications. The results revealed that variety, nutrient management and their interaction exerted significant influence on yield components and yield of aromatic fine rice in Boro season. The highest grain yield (4.09 t ha^-1), straw yield (6.20 t ha^-1) and harvest index (39.37%) were obtained in BRRI dhan63 while the lowest grain yield (3.44 t ha^-1) and harvest index (36.54%) were found in Basmati. In case of nutrient management, the highest grain yield (4.31 t ha^-1) was recorded in recommended dose of chemical fertilizers (i.e. 250, 126, 120, 100 and 10 kg N-P-K-S-Zn, respectively ha^-1) which was as good as 25% less than recommended dose of chemical fertilizer + vermicompost @ 5 t ha^-1 and 25% less than recommended dose of chemical fertilizer + poultry manure @ 2.5 t ha-1 while the lowest one (2.74 t ha^-1) was found in vermicompost @ 10 t ha^-1. In case of interaction, the highest grain yield (5.30 t ha^-1) was obtained in BRRI dhan63 along with 50% less than recommended dose of chemical fertilizer + vermicompost @ 10 t ha^-1 while the highest straw yield (7.20 t ha^-1) was produced in BRRI dhan63 fertilized with recommended dose of chemical fertilizers (i.e. 250, 126, 120, 100 and 10 kg N-P-K-S-Zn, respectively ha^-1). Therefore, it can be concluded that BRRI dhan63 can be grown with 50% less than recommended dose of chemical fertilizer + vermicompost @10 t ha^-¹ in Boro season to obtain the highest grain yield.

Objectives:

Extensive research works are necessary to find out appropriate variety and optimum rate of poultry manure, vermicompost in combination with inorganic fertilizers to obtain satisfactory yield and quality of fine rice.

Methodology:

Description of study site The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, during November 2016 to April 2017. This experimental site is located at 24^°75 ' N latitude and 90^°50'E longitude having an altitude of 18m. The experimental site belongs to the Sonatala series of Old Brahmaputra Floodplain Agroecological Zone (AEZ-9) having non-calcareous dark grey floodplain soils (UNDP and FAO, 1988). Experimental design and treatment details The experiment consisted of three varieties viz. BRRI dhan50, Basmati and BRRI dhan63, and seven nutrient managements viz., poultry manure 5 t ha^-1, recommended dose of chemical fertilizers (i.e. 250, 126, 120, 100 and 10 kg N-P-K-S-Zn, respectively ha-1), 25% less than recommended dose of chemical fertilizer + poultry manure @ 2.5 t ha^-1,50% less than recommended dose of chemical fertilizer + poultry manure @ 5 t ha^-1, vermicompost @ 10 t ha^-1, 25% less than recommended dose of chemical fertilizer + vermicompost @ 5 t ha^-1, 50% less than recommended dose of chemical fertilizer + vermicompost @ 10 t ha^-1. The experiment was laid out in a randomized complete block design with three replications. At the time of final land preparation, respective unit plots were fertilized with different levels of vermicompost, poultry manure according to treatments. The manures were thoroughly mixed with the soil. The amount of nitrogen, phosphorus, potassium, sulphur and zinc required for each unit plot was calculated on ha-1basis and applied in the form of urea, triple super phosphate, muriate of potash, gypsum and zinc sulphate, respectively. Triple super phosphate, muriate of potash, gypsum and zinc sulphate was applied at final land preparation as per treatment. Urea was applied in three equal splits at 15, 30 and 45 days after trans-planting (DAT). Transplantation of seedlings and collection of data Thirty-five days old seedlings were uprooted carefully without causing any mechanical injury to the root. Healthy seedlings were transplanted in the well puddled experimental plots on 21 December 2016. Intercultural operations were done for ensuring and maintaining normal growth of the crop when necessary. Prior to harvest five hills (excluding border hills) were selected randomly from each unit plot and uprooted to record data on crop characters and yield components. After sampling, the whole plot was harvested at maturity when 90% of the grains became golden yellow in color. BRRI dhan63 was harvested on 23 April, 2017 and BRRI dhan50 and Basmati were harvested on 30 April 2017. The harvested crops of each plot was separately bundled, properly tagged and then brought to threshing floor. Threshing was done manually. The grains were cleaned and sun dried to 14% moisture content. Straws were also dried properly. Finally grain and straw yields plot-1were recorded and converted to t ha^-1. Harvest index (%) was calculated with the following formula: Harvest index (100) = Grain yield/Biological yield x 100.

Statistical analysis of data Data were analyzed statistically using “Analysis of Variance” technique and differences among treatments means were adjudged by Duncan’s Multiple Range Test (DMRT) (Gomez and Gomez, 1984).

Achievement/Findings:

The results of this investigation revealed that the highest grain and straw yields were obtained in BRRI dhan63. Application of recommended dose of chemical fertilizers (i.e. 250, 126, 120, 100 and 10 kg N-P-K-S-Zn, respectively ha^-1) produced the high-est grain yield (4.31 t ha^-1) which was at par with 25% less than recommended dose of chemical fertilizer + vermicompost @ 5 t ha^-¹ and 25% less than recommended dose of chemical fertilizer + poultry manure @ 2.5 t ha^-1 while the lowest one (2.74 t ha^-1) was found in vermicompost @ 10 t ha^-1. BRRI dhan63 fertilized with 50% less than recommended dose of chemical fertilizer + vermicompost @ 10 t ha^-1 produced the highest grain yield while the highest straw yield (7.20 t ha^-1) was produced in BRRI dhan63 fertilized with recommended dose of chemical fertilizers (i.e. 250, 126, 120, 100 and 10 kg N-P-K-S-Zn, respectively ha^-1). Therefore, it can be concluded that BRRI dhan63 can be grown with 50% less than recommended dose of chemical fertilizer + vermicompost @10 t ha^-¹ in Boro season to obtain the highest grain yield.
