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 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.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from April to August 2011 to find out the effect of spacing and number of seedlings hill-1 on the performance of Aus rice cv. NERICA 1. Four spacing viz. 25 cm × l5 cm, 20 cm × l5 cm. 20 cm × 10 cm and 15 cm × 10 cm and four number of seedlings hill-1 viz. 2, 3, 4 and 5 were included in the experiment. The experiment was laid out in a randomized complete block design with three replications. The highest number of total tillers m-2, number of effective tillers m-2, number of grains panicle-1, grain yield, straw yield, biological yield and harvest index were obtained from 20 cm × 10 cm spacing. Plant height and 1000- grain weight were not significantly affected by spacing. Number of seedlings hill-1 exerts a significant effect on plant height. The highest value of total tillers m-2, number of effective tillers m-2, total grains panicle-1, grain yield, straw yield, biological yield and harvest index were obtained from five seedlings hill-1. The interaction between spacing and number of seedlings hill-1 significantly influenced yield and plant characters. The highest number of effective tillers m-2, grains panicle-1, grain yield, straw yield and biological yield were recorded from the interaction between 20 cm × 10 cm and five seedlings hill-1.

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

Boro Rice

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during the period from November 2010 to May 2011 to study the effect of variety and rate of nitrogen on the performance of Boro rice. The experiment comprised three varieties viz., BRRI dhan28 (V1), BRRI dhan29 (V2) and BRRI dhan45 (V3); and five rates of nitrogen viz., control (N0), 50 kg  (N1), 100 kg (N2), 150 kg  (N3)and 200 kg  (N4) N ha-1. The experiment was laid out in a randomized complete block design with four replications. The growth analysis results indicate that the tallest plant (80.88 cm) and the highest number of total tillers hill-1 (13.80) were observed in BRRI dhan29 at 70 DATs and the highest total dry matter (66.41 g m-2) was observed in BRRI dhan45. The shortest plant (78.15 cm) and the lowest number of tillers hill-1 (12.41) were recorded from BRRI dhan45 and the lowest dry matter (61.24 g) was observed in BRRI dhan29. The tallest plants (84.01 cm), highest number of tillers hill-1 (14.06) and the highest dry matter (69.58 g m-2) were obtained from 200 kg N ha-1. The tallest plants (86.48 cm) and maximum dry matter (72.30 g m-2) were recorded from BRRI dhan28 with 200 kg N ha-1 and BRRI dhan45 with 200 kg N ha-1, respectively. The highest number of tillers hill-1 (15.14) was obtained from BRRI dhan29 with 50 kg N ha-1. The harvest data reveal that variety had significant effect on total tillers hill-1, effective tillers hill-1, non-effective tillers hill-1, panicle length, grain yield, straw yield and harvest index. The highest grain yield (4.84 t ha-1) was recorded from BRRI dhan29. The results of the experiment also indicate that total tillers hill-1, effective tillers hill-1, grains panicle-1, sterile spikelets panicle-1, grain yield, straw yield and harvest index were significantly affected by levels of nitrogen, while plant height, panicle length, 1000-grain weight were not significantly affected by levels of nitrogen. The highest grain yield (5.58 t ha-1) was obtained from 200 kg N ha-1. Interaction effect of variety × 200 kg N ha-1 produced the highest grain yield (5.82 t ha-1). From the results of the study it may be concluded that BRRI dhan29 rice may be cultivated with 200 kg N ha-1 for obtaining higher yield in AEZ 9 of Bangladesh.Progressive Agriculture 26:6-14, 2015

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 carried out at Bangladesh Agricultural University, Mymensingh to evaluate the effect of urea super granule (USG) as a source of nitrogen on the yield and yield components of transplant Aman rice cv. BRRI dhan39, BRRI dhan46 and BINA dhan7. Five levels of N (viz., 0, 60, 120 kg ha-1 as prilled urea and 60 and 120 kg ha-1 as USG) were taken as experimental treatments. The experiment was laid out in a randomized complete block design with three replications. Plant height, effective tillers hill-1, grains panicle-1 and grain yield varied significantly due to different cultivars. All the yield and yield components except 1000-grain weight were influenced significantly by the levels of nitrogen fertilizer. The highest grain yield (4.82 t ha-1) was recorded in BINA dhan7 and the lowest one (4.30 t ha-1) was recorded in BRRI dhan39. Nitrogen @ 120 kg ha-1 as USG performed the best among the treatments in respect of yield and yield components of rice. The highest grain yield (5.46t ha-1) was obtained from BINA dhan7 with 120 kg N ha-1 as USG which was statistically identical with 60 kg N ha-1 as USG. A considerable amount (31.25%) of prilled urea (PU) nitrogen could be saved by using USG. It may be concluded that USG could be used as N management to achieve better nitrogen use efficiency in reducing N loss than the PU.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19095 Progress.

A field experiment was conducted at the Agrotechnology Field Laboratory of Khulna University during the boro season to evaluate the effect of planting density on the performance of rice variety BRRI dhan28. The experiment received twelve treatments, which were divided into two distinct patterns - single row and paired row. The single row had four treatments and paired row had eight treatments. Planting densities were 40, 27, 20 and 16 hills m-2. The experiment was arranged in a randomized complete block design (RCBD) with three replications. Standard management practices were followed in raising crops. Results revealed that closer spacing produced higher yields where 40 hills m-2 produced the most (4.81 t ha-1), which was statistically similar with that of 27 hills   m-2. Paired row planting showed better performance than single row planting. Plant height, grains panicle-1, sterile spikelets panicle-1, 1000-grain weight, grain yield were found better in paired row planting. Paired row planting at a spacing of (35 cm + 15 cm) × 10 cm  i.e row to row distance is 35 cm & 15 cm and hill to hill distance is 10 cm; found the highest grain yield (4.81 t ha-1) and the lowest yield (2.97 t ha-1) was found in single row using a spacing of 25 cm × 25 cm.Bangladesh Agron.

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 of Patuakhali Science and Technology University, Dumki, Patuakhali from June to December, 2013 to find out the effect of variety and planting density on the yield and yield attributing characters of local aromatic rice. The experiment was laid out in a factorial randomized complete block design with three replications, which consisted of three local aromatic rice varieties (Chinigura, Shakhorkhora and Kalizira) and four planting densities were viz. S1 (25 cm × 20 cm), S2 (20 cm × 20 cm), S3 (20 cm × 15 cm) and S4 (20 cm × 10 cm). The results revealed that the local aromatic rice var. Shakhorkhora variety produced the highest number of grains per panicle (131) and 1000-grain weight (13.8 g), consequently higher grain (2.63 t ha-1), followed by Kalizira (2.56 t ha-1) and straw yield (4.21 t ha-1). One the other hand, higher number of tillers per hill (14.8), number of grains per panicle (140 nos.) were found in 20 cm × 20 cm spacing with higher grain yield.Bangladesh J. Agril.

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
