Boro Rice

Performance of salt-tolerant Boro rice was investigated under the interaction effect of variety and different doses of potassium fertilizer, which is a part of the research for developing agriculture in coastal areas of Bangladesh. A field experiment was conducted at the research field of Agriculture department, Noakhali Science and Technology University (NSTU), Noakhali-3814. The experiment was carried out in a Randomized Complete Block Design (RCBD) with three replications where two varieties viz. BINA dhan-8, BRRI dhan-28 and three doses of potassium viz. 120 kg/ha, 84 kg/ha and 36kg/ha were used as treatments. Plant height (cm), tillers/hill, grain/panicle, 1000 grain weight (g), grain yield (t/ha), straw yield (t/ha) and harvest index (%) were compared among varieties and treatments. Results revealed that only variety and only potassium fertilizer had non-significant influence but the interaction of variety and potassium fertilizer had a significant effect on the performance of salt-tolerant Boro rice. Therefore, the present study suggests that salt-tolerant BINA dhan-8 variety may be cultivated with 120 kg potassium/ha for obtaining higher yield in the southern coastal area of Bangladesh.

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 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.

BRRI dhan52). The experiment consisted of two ages of tiller seedlings viz. 25 and 35-days old, three levels of tiller seedlings hill-1 viz. 1, 3 and 5 seedlings hill-1 and three levels of USG viz. 0, 1.8 (55 kg N ha-1) and 2.7g USG (80 kg N ha-1) four hill-1 in every alternate row. The experiment was laid out in a Randomized Complete Block Design (Factorial) with three replications. The highest plant height, number of effective tillers hill-1, number of total tillers hill-1, number of total spikelets panicle-1, number of grains panicle-1, grain yield and harvest index were found in 1.8 g USG applied @ one granule 4-hill-1. The highest number of sterile spikelets panicle-1 was found in control treatment and the lowest in 1.8 g USG. The highest number of effective tillers hill-1, number of total spikelets panicle-1 and grain yield ha-1 was found when 5 tiller seedlings were transplanted hill-1 combined with 1.8 g USG. Application of urea super granules 1.8 g (55 kg N ha-1) at 10 days after transplanting @ one granule 4-hill-1 in every alternate row with 25 day old tiller seedlings using 5 tiller seedlings hill-1 was found beneficial for grain yield of transplant Aman rice. Tiller separation could be an alternative source of seedling during seedling scarcity.Bangladesh J. Agril. Res. 40(4): 581-590, December 2015

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during November 2014 to April 2015 to investigate the effect of planting spacing and nitrogen levels on yield attributes and yield of maize cv. Khaibhutta. The experiment comprised three nitrogen levels viz. 50, 100 and 150 kg N ha-1 and five plant spacings viz. 75 cm × 25 cm, 75 cm × 20 cm, 50 cm × 25 cm, 50 cm × 20 cm and 100 cm × 20 cm. The experiment was laid out in a randomized complete block design with three replications. Results revealed that nitrogen levels and plant spacing had significant effect on yield attributes and yield of Khaibhutta. The highest number of cobs plant-1, grains row-1, grain yield and stover yield were recorded with 150 kg N ha-1 followed by 100 kg N ha- 1and the lowest values were observed in 50 kg N ha-1. The highest number of cobs plant-1, grain rows cob-1, grains row-1, grains cob-1, 1000-grain weight, grain yield and harvest index were recorded at 75 cm × 25 cm spacing. In contrast, the closest spacing of 50 cm x 20 cm produced the lowest values of grain rows cob-1, grains row-1, grains cob-1, 1000-grain weight and grain yield. In case of interaction, the highest grain yield and harvest index were obtained at 75 cm × 25 cm spacing fertilized with 150 kg N ha-1. The lowest values of the above parameters were recorded in the closest spacing 50 cm × 20 cm with 50 kg N ha-1. From this study it may be concluded that maize (cv. Khaibhutta) can be cultivated at the spacing of 75 cm × 25 cm with 150 kg N ha-1 for appreciable grain yield.J. Bangladesh Agril. Univ. 14(1): 43-48, June 2016

Boro Rice

The experiment was conducted during December 2012 to June 2013 in the farmer’s field adjacent to Bangladesh Agricultural University (BAU), a village named Boira under Sadar Upazilla of Mymensingh to study the yield performance of Boro rice in response to USG. The experiment comprised two rice varieties viz. Binadhan-5 and BRRI dhan29 and seven levels of USG viz.i) prilled urea (PU) 280 kg ha-1(control),ii)USG 1.8g/4 hills in every alternate row applied at 5 cm depth, iii) USG 1.8g/4 hills in every alternate row applied at 10 cm depth, iv) USG 2.7g/4 hills in every alternate row applied at 5 cm depth, v)USG 2.7g/4 hills in every alternate row applied at 10 cm depth, vi) USG 3.6g/4 hills in every alternate row applied at 5 cm depth and vii)USG 3.6g/4 hills in every alternate row applied at 10 cm depth. The experiment was laid out in a randomized complete block design with three replications. Variety, level of USG and their interaction exerted significant influence on yield contributing characters and yield of Boro rice. BRRI dhan29 produced higher number of effective tillers hill-1 and heaviest grain than that of Binadhan-5. As a result of superior yield parameters, BRRI dhan29 gave higher yield (7.67 t ha-1) than Binadhan-5 (6.52 t ha-1). In case of USG, the highest number of total tillers hill-1, grains panicle-1, 1000-grain weight and grain yield (7.59 t ha-1) were obtained from USG @ 3.6g/4 hills in every alternate row applied at 5cm depth. The lowest values of all the parameters were obtained from PU. Considering their interaction effect, BRRI dhan29 with USG 3.6g/4 hills in every alternate row applied at 5cm depth produced best yield attributes, grain (8.38 t ha-1) and straw yield (9.26 t ha-1). The lowest performance was observed in Binadhan-5 with PU. The overall results suggest that farmers can be advised to cultivate BRRI dhan29 fertilized with USG 3.6g/4 hills in every alternate row at 5 cm depth for getting highest yield in Boro season under the agro-climate condition of the study area.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.
