An investigation was carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University to inspect the effect of vermicompost based nitrogen management and plant spacing on the yield performance of short duration transplant Aus rice (cv. Parija). The study comprised three spacing viz. 20 cm × 20 cm, 20 cm × 15 cm and 20 cm × 10 cm, and five nitrogen management viz. no nitrogen, 75 kg N ha-1, 55 kg N ha-1 + vermicompost @1.25 t ha-1, 35 kg N ha-1 + vermicompost @2.5 t ha-1 and vermicompost @5 t ha-1. The experiment was laid out in a Randomized Complete Block Design with three replications. At harvest, both the spacing of 20 cm × 20 cm and 20 cm × 15 cm produced the tallest plants, the highest number of total tillers hill-1 and effective tillers hill-1. The highest grain yield (3.59 t ha-1) was recorded in 20 cm × 15 cm spacing which was at par with the grain yield (3.52 t ha-1) in 20 cm × 10 cm spacing. The 20 cm × 10 cm spacing also produced the highest straw yield (4.88 t ha-1) and biological yield (8.40 t ha-1). The lowest grain, straw and biological yields were recorded at the wider spacing of 20 cm × 20 cm. In contrast, the highest grain yield (3.79 t ha-1), straw yield (4.99 t ha-1) and biological yield (8.79 t ha-1) were found in 75 kg N ha-1 which was as good as the yields of 55 kg N ha-1 N+ vermicompost @1.25 t ha-1. The highest number of total tillers hill-1 (14.11) and effective tillers hill-1 (12.67) were found in the interaction effect of 20 cm × 20 cm spacing with 75 kg N ha-1. The interaction between 20 cm × 15 cm and 55 kg N ha-1 N+ vermicompost @1.25 t ha-1 gave the highest grain yield (4.58 t ha-1), straw yield (5.71 t ha-1) and biological yield (10.29 t ha-1). The lowest grain yield (2.03 t ha-1), straw yield (3.49 t ha-1) and biological yield (5.52 t ha-1) were found in the interaction between 20 cm × 20 cm and no nitrogen. Therefore, usage of 20 cm × 15 cm spacing fertilized with 55 kg N ha-1 + vermicompost @1.25 t ha-1 appeared as the promising practice of transplant Aus rice cv. (Parija) cultivation.

Plant spacing ensures uniform and optimum plant population and facilitates sufficient natural resources for crop growth which, in turns influences the crop yield positively. An investigation was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, during July to December 2017 to study the influence of plant spacing on the yield of double grained rice cultivar. The study comprised five spacing viz. 25 cm × 15 cm, 25 cm × 10 cm, 20 cm × 15 cm, 20 cm × 10 cm and 15 cm × 15 cm and two rice cultivars viz. a double grained rice cultivar and BRRI dhan49 and a double grained rice cultivar. It was laid out in a randomized complete block design with three replications. The double grained rice cultivar produced taller plant (155.65 cm), longer panicle (23.93 cm), higher 1000-grain weight (25.96) and higher straw yield (6.90 t ha-1), though the higher grain yield (3.68 t ha-1) was found in the test cultivar (BRRI dhan49). Planting at 20 cm × 15 cm produced the highest grain yield (3.70 t ha-1) which was at par with 25 cm × 15 cm, 25 cm × 10 cm and 20 cm × 10 cm while planting at 15 cm × 15 cm produced the lowest grain yield (3.13 t ha-1). The interaction of the double grained rice cultivar with all spacing combinations produced taller plants than the spacing combinations with BRRI dhan49. The higher grain yield (3.52 t ha-1) was found in the double grained rice cultivar with 20 cm × 10 cm spacing which was at par with the spacing of 20 cm × 15 cm and 25 cm × 15 cm, respectively; although BRRI dhan49 always produced the higher yield. The lowest grain yield (3.08 t ha-1) was recorded at the double grained rice cultivar with 25 cm × 10 cm spacing, however, the same treatment produced the highest biological yield (11.23 t ha-1) due to the highest straw yield (8.15 t ha-1). Hence, the spacing 20 cm × 15 cm might be recommended for the higher grain yield in the double grained rice cultivar Res. Agric., Livest. Fish.8(3): 273-279, December 2021

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from July to December 2012 to observe the effect of variety, age of tiller seedling used for transplanting and nitrogen management on the yield performance of transplant Aman rice. The experiment consisted of two varieties viz. BRRI dhan49 and BRRI dhan51, two ages tiller seedling viz. 25- and 35-day old, five nitrogen management viz. control (no urea), application of prilled urea @ 215 kg ha-1 (1/2 at 15 DAT+1/2 at 30 DAT), prilled urea @ 215 kg ha-1 (1/3 at 15DAT+1/3 at 30DAT+1/3 at 45DAT ), urea super granules (USG) 1.8 g and USG 2.7 g four-hill-1 in every alternate row. The experiment was laid out in randomized complete block design with three replications. The results revealed that higher plant characters, straw yield and harvest index were obtained from BRRI dhan49 compared to BRRI dhan51. Older seedlings (35-day old) produced higher grain yield to younger seedlings. The highest yield contributing characters and grain yield were obtained when 1.8g USG was applied. The grain yield was highest in 35-day old tiller seedlings of BRRI dhan51 while fertilized with 1.8g USG. This value was lowest when 25-day old tiller seedlings of BRRI dhan51 were fertilized with prilled urea in two split applications. It may be concluded that 35-day tiller seedlings of BRRI dhan51 fertilized with USG 1.8 g four-hill-1 could be used for achieving higher yield of transplant Aman rice.

A field experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from July to December 2011 to evaluate the effect of variety and placement method of urea super granule (USG) on the yield performance of T. aman rice varieties. The experiment consisted of three aman rice varieties viz., Pajam, BR11, BRRI dhan40 and four placement methods viz., broadcasting method of prilled urea (PU), USG placement by hand, by BAU USG applicator and by BARI USG applicator. The experiment was laid out in a randomized complete block design with four replications. The highest value of grain yield (5.13 t/ha), straw yield (5.90 t/ha) and biological yield (11.04 t/ha) were found in BR11. On the other hand, the lowest grain yield (3.54 t/ha) was produced in variety Pajam. The highest grain and straw yields (5.13 and 5.21 t/ha, respectively) were obtained from the hand placement method of USG. Regarding the interaction of variety and USG placement method, BR11with hand placement method appeared as the best method among others. DOI: http://dx.doi.org/10.3329/jbau.v12i1.21183 J.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during June to December 2014 with a view to finding out the effect of variety and level of nitrogen on the yield performance of fine aromatic rice. The experiment consisted of three varieties viz. Kalizira, Binadhan-13 and BRRI dhan34, and six levels of nitrogen viz. 0, 30, 60, 90 kg N ha-1, USG 1.8 g 4 hills-1 (55 kg N ha-1) and USG 2.7 g 4 hills-1 (80 kg N ha-1). The experiment was laid out in a randomized complete block design with three replications. Variety, level of nitrogen and their interaction significantly influenced the yield of aromatic rice. The highest grain yield (3.33 t ha-1) was obtained from Binadhan-13 followed by BRRI dhan34 (3.16 t ha-1) and the lowest grain yield was found in Kalizira (2.11 t ha-1). In case of N, the tallest plant (140.3 cm), highest number of effective tillers hill-1 (11.40), grains panicle-1 (152.8), and grain yield (3.32 t ha-1) were obtained when fertilized with USG 1.8 g 4 hills-1 and the lowest values were found in 0 kg N ha-1. Therefore, Binadhan-13 fertilized with USG 1.8 g 4 hills-1 (55 kg N ha-1) appeared as the promising practice for appreciable grain yield.J. Environ. Sci. & Natural Resources, 9(1): 41-45 2016

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December 2004 to evaluate the effect of hill spacing on the performance of BRRI dhan40 and BRRI dhan41 as Transplant aman crop. The experiment consisted of five hill spacings viz., 5cm. 10cm, 15 cm, and 25 cm where row to row spacing of 25 cm was kept constant for all treatments. The experiment was laid out in randomized complete block design with four replications. The 25 cm x 5 cm hill spacing produced the tallest plant, highest total number of tillers/hill, bearing tillers/hill lowest number of non-hearing tillers/hill, grain yield and harvest index, while 25 cm x 5 cm hill spacing produced the highest number of sterile spikelets/panicle, straw yield and biological yield. BRRI dhan41 produced higher grain yield (4.7 t/ha) which was the contribution of higher number of grains/panicle and heavier grain weight. Lower yield (4.51 t/ha) was recorded in BRRI dhan40.Key Words: Varietal performance; T. aman rice; hill density.DOI: 10.3329/bjar.v34i1.5750Bangladesh J. Agril. Res. 34(1) : 33-39, March 2009

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, Bangladesh to investigate the influence of plant nutrient management on the yield performance of transplant Aman rice. The experiment comprised two Aman rice varieties viz. Binadhan-15 and Binadhan-16, and ten nutrient management viz. Recommended dose of inorganic fertilizer (RDF) Urea-TSP-MoP-Gypsum-ZnSO4 @ 150-110-70-60-5 kg ha-1, Cowdung @ 10 t ha-1, Poultry manure @ 5 t ha-1, Vermicompost @ 3 t ha-1 , 25% less than RDF + cowdung @ 5 t ha-1, 50% less than RDF + cowdung @ 10 t ha-1 , 25% less than RDF + poultry manure @ 2.5 t ha-1, 50% less than RDF + poultry manure @ 5 t ha-1, 25% less than RDF + vermicompost @ 1.5 t ha-1, 50% less than RDF + vermicompost @ 3 t ha-1. The experiment was laid out in a randomized complete block design with three replications. Binadhan-15 produced taller plants (97.86 cm), effective tillers hill-1 (6.28), grains panicle-1 (101.73), higher grain (3.58 t ha-1) and straw (4.99 t ha-1) yields compared to Binadhan-16. In case of nutrient management, 50% less than RDF + poultry manure @ 5 t ha-1 produced taller plants (101.1 cm), effective tillers hill-1 (7.07), grains panicle-1 (105.1) and grain yield (4.08 t ha-1). The highest grain yield (4.25 t ha-1) was recorded in Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 and the lowest grain yield (2.28 t ha-1) was obtained in Binadhan-16 fertilized with vermicompost @ 3 t ha-1. So, it can be concluded that transplant Aman rice cv. Binadhan-15 fertilized with 50% less than RDF + poultry manure @ 5 t ha-1 appears as the promising practice to obtain the highest grain yield.

Effect Of Age

The experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh during the period from July to October 2016 to study the effect of age of seedling on the yield and yield contributing characters of short duration Aman rice cultivars. The study consisted two factor A: Variety- three- i)    BINA dhan7 (V1),   (ii) BRRI dhan56 (V2) and (iii)  BRRI dhan62 (V3); and factor B: Number of seedlings hill-1- (i)   Single seedling  hill-1 (S1), (ii)  Two seedlings  hill-1 (S2) and (iii) Three seedlings  hill-1 (S3). The experiment was laid out in a randomized complete block design with three replications. The highest grain yield was obtained from the cultivar BINA dhan7 which was statistically identical with BRRI dhan56 and this was the consequences of higher number of total and effective tillers hiil-1 and highest number of grains panicle-1. Grain yield was not significantly affected by the number of seedlings hill-1 but numerically the highest grain yield was recorded from single seedling hill-1. From the interaction it is observed that grain yield was not significantly affected by the interaction of cultivar and number of seedlings hill-1. But numerically the highest grain yield was recorded from the interaction of BRRI dhan56 × single seedling hill-1. From the economic analysis it is observed that the highest BCR (1.64) was recorded from single seedling hill-1 in BRRI dhan56 which was close to single seedling hill-1 in BINA dhan7 and the lowest BCR (103) was obtained from two seedlings hill-1 in BRRI dhan62. From the results of the study it may be concluded that BRRI dhan56 with single seedling hill-1 might be cultivated in AEZ-9 for obtaining higher yield and higher economic return in Aman season.Progressive Agriculture 28 (4): 279-286, 2017
