The present investigation was executed at Agricultural Research Field, Noakahali Science and Technology University, Noakhali, Bangladesh to access the effects of variety and integrated application of vermicompost, biochar and urea on efficiency of boro rice yield. The experiment was accomplished during the period from November 2018 to May 2019. It was completed in a randomized complete block design (RCBD) with three replications. The treatments assigned in a factorial arrangement of 2 × 4, with 2 varieties of rice (V1-BINA dhan 8, V2- BINA dhan 10) and 4 integration of vermicompost, biochar, and urea (T1: Vermicompost-2.5 t ha-1, T2: Vermicompost-2 t ha-1+ Biochar 0.5 t ha-1, T3: Vermicompost-1.5 t ha-1+ Biochar 1 t ha-1 and T4: Vermicompost-1.5 t ha-1 + Urea-150kg ha-1/0.15 t ha-1). Data were collected to analyze growth and yield contributing characters of boro rice. All the parameters were not statistically significant to differ. According to variety highest grain (3.73 t ha-1) and straw (2.8 t ha-1) yield was found from BINA dhan 10 in comparison with BINA dhan 8. In case of integrated application of vermicompost, biochar and urea, superior grain and straw yield were obtained from T4: Vermicompost-1.5 t ha-1 + Urea-0.15 t ha-1 whereas lowest grain yield (3.01 t ha-1 recorded from integrated application vermicompost and biochar. In combine maximum grain (4.92 t ha-1) and straw (4.40 t ha-1) yield was noted from BINA dhan 10 alone with integrated application of vermicompost and urea whereas the lowest data (grain: 2.50 t ha-1; straw: 1.64 t ha-1) was found from BINA dhan 8 along with vermicompost and biochar.

An experiment was conducted to find out the effect of variety, date of transplanting and its interaction on the growth and yield performance of high yielding Boro rice. The experiment comprised five varieties viz., BRRI dhan28, BRRI dhan58, BRRI dhan67, BRRI dhan69, BRRI dhan74 and five dates of transplanting viz., 15 December, 30 December, 15 January, 30 January and 15 February. The experiment was laid out in a randomized complete block design with three replications. Results revealed that growth parameters, crop characters, yield components and yield were significantly influenced by variety, date of transplanting and their interactions. The leaf area index (LAI) and dry matter production hill-1 were highest in BRRI dhan69 when transplanted on 15 January whereas the lowest value was found in BRRI dhan28 when transplanted on 15 February. The number of effective tillers hill-1 (11.80), number of grains panicle-1 (130.90), 1000-grain weight (22.07 g), grain yield (4.96 t ha-1) and straw yield (6.64 t ha-1) were highest in BRRI dhan69 whereas corresponding lowest values were recorded in BRRI dhan28. The crop transplanted on 15 January produced the highest number of effective tillers hill-1 (12.81), highest number of grains panicle-1 (131.20), heaviest 1000-grain weight (21.93 g), highest grain yield (5.36 t ha-1) and highest straw yield (7.71 t ha-1). In case of interaction, the highest grain (5.90 t ha-1) and straw yields (7.87 t ha-1) were recorded in BRRI dhan69 transplanted on 15 January whereas the lowest grain and straw yields were recorded in BRRI dhan28 transplanted on 15 February. Therefore, it can be concluded that BRRI dhan69 along with 15 January transplanting appears as the promising combination in terms of grain and straw yields.

An experiment was conducted during 20 November 2015 through March 20I6 to assess the effect of planting dates on growth and yield performance of three potential varieties of potato at Plant Physiology research field, Bangladesh Agricultural Research Institute, Gazipur. Three planting dates (November 20, December 5 and December 29) and three varieties (var. BARI Alu-35, BARI Alu-40 and BARI Alu-41) were the treatment variables. The experiment was laid out in a randomized complete block design with three replications. Maximum plant height (42.3 cm) was observed in 5 December sowing in var. BARI Alu-40. Highest number of tuber/plant (13) was recorded from December 5 sowing in var. BARI Alu-41. The highest leaf area was found in December 5 sowing of BARI Alu-40 while the lowest leaf area in November 20 sowing in var. BARI Alu-35. The highest tuber weight/plant (97.25 g) was observed in var. BARI Alu-5 at December 5 sowing and the lowest tuber weight/plant (25.58 g) in var. BARI Alu-35 at November 20 sowing. The maximum potato yield (42.12 t/ha) was obtained at December 5 sowing of BARI Alu-35 followed by same date of var. BARIAlu- 41. From the experiment it was revealed that the first decade of December is the optimum date for planting of potato due to the physiological maturity and tuber yield.Bangladesh Agron.

Correction: In the last line of the abstract, the word 'increase' was replaced with the word 'reduced' on 25th November 2015. The correct sentence now reads "The application of PRH, Calsol and Magic Growth significantly reduced rice yield than that obtained with recommended fertilizer dose."AbstractInherent soil fertility and application of exogenous fertilizer generally affect rice yield. Fertilization would be soil fertilization or foliar feeding through leaf area. Plant growth promoting substances also improve plant performance through modulation of its growth and yield. The study was conducted at BRAC Agricultural Research and Development Center (BARDC), Gazipur. The aim of the study was to find out the growth and yield of Boro rice as influenced by plant revitalization hormone (PRH) and liquid fertilizer Calsol and Magic Growth during dry season 2012-13 using randomized complete block design with three replications. Treatment consists of; T1=Recommend fertilizer dose of NPKS and Zn (Control), T2=T1+ recommended PRH, T3=T2 + half of the PRH, T4=Half of doses of T1 + PRH, T5=PRH, T6=Recommended fertilizer dose of NPK with three N top dressed along with Calsol, T7=Recommended fertilizer dose of NPK with 1st and 3rd split of N application and along with three split of Calsol application, T8=Recommended dose of liquid fertilizer Magic Growth. The effect of different treatment combinations of PRH and liquid fertilizer Calsol and Magic Growth showed significant difference (p<0.05) in panicle m-2, unfilled grain panicle-1, total grain panicle-1, and grain yield. However, none of the treatments out yielded the existing fertilizer application method. The application of PRH, Calsol and Magic Growth significantly reduced (corrected on 25th Nov. 2015) rice yield than that obtained with recommended fertilizer dose.Bangladesh Rice j. 2015, 19(1): 33-39

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.

The purpose of this study was to assess the variation on agro-morphological traits and grain yield. A set of 14 early maize genotypes were studied at research field of Regional Agricultural Research Station (RARS), Doti, Nepal in summer seasons of 2015 and 2016. The experiment was carried out in Randomized Complete Block Design (RCBD) with three replications in each year. The variation among genotypes was observed for grain yield and flowering. The genotype SO3TEY-PO-BM produced the highest grain yield (4.33 t/ha) in 2015 whereas Rajahar Local Variety produced the highest grain yield (2.52 t/ha) in 2016. The combined analysis over years showed that Farmer’s variety was found earlier in tasseling (36 days) and silking (39 days), followed by S97TEYGHAYB(3) in tasseling (45 days) and by S97TEYGHAYB(3) and Arun-4 in silking (48 days). EEYC1 produced the highest grain yield (3.17 t/ha), followed by COMPOL-NIBP (3.09 t/ha), SO3TEY-PO-BM (2.90 t/ha), S97TEYGHAYB(3) (2.78 t/ha) and Rajahar Local variety (2.77 t/ha), respectively. The information on variation for the agro-morphological traits among studied early maize genotypes will be helpful to plant breeders in constructing their breeding materials and implementing selection strategies.

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during April to November, 2012 to study the combined effects of Sesbania green manure incorporation with different levels of nitrogen fertilizer on the growth and yield of BINA dhan7. There were five treatments for using Sesbania as pre-rice green manure (GM): Fallow (No GM), GM for incorporation at 40, 50, 60, and 70 days after sowing (DAS). T. Aman was planted after chopping the GM. For T. aman there were 9 treatments: Fallow plot received full dose (180 kg urea ha-1) of N fertilizer while plots with GM received 50 and 75% of recommended N fertilizer. The experiment was laid out in a Randomized Complete Block Design with three replications. The highest grain yield of 5752 kg ha-1 and straw yield of 6654 kg ha-1 were observed in the plot treated with 75%recommended dose of nitrogen (RDN) and green manure incorporated at 50 DAS. The lowest grain yield (4783 kg ha-1) and straw yield (5154 kg ha-1) were recorded with GM incorporated at 40 DAS + 50% RDN. The N content and uptake by the grain and straw were differed significantly due to different treatments and maximum uptake was recorded with the application of 75% recommended dose of nitrogen (RDN) and green manure incorporated at 50 DAS. The overall results indicate that application of Sesbania green manure incorporated at 50 DAS in combination with 75% recommended dose of nitrogen could be considered more effective for BINA dhan7 production DOI: http://dx.doi.org/10.3329/sja.v12i2.21925 SAARC J.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during November 2008 to April 2009 to evaluate the effect of row and hill spacings on the yield of rice (cv. BRRI dhan45) under aerobic system of cultivation in boro season. Aerobic system is a new water efficient rice production system where the crop is grown by direct seeding on well prepared dry beds and also by maintaining the soil moisture at field capacity during the growing period. The experiment consisted of two row to row spacings viz. 20 and    25 cm, and five hill to hill spacings viz., 2.5, 5, 10, 15 and 20 cm. The trial was laid out in a randomized complete block design with 3 replications. Results revealed that the crop sown at 25 cm ×15 cm produced the highest grain yield of 5.69 t ha-1 whereas the lowest grain yield of 2.11 t ha-1 was found with 20 cm × 2.5 cm spacing. The present study concludes that the highest grain yield of BRRI dhan45 during boro season under aerobic system of cultivation could be achieved by sowing at 25 cm ×15 cm spacing.   DOI: http://dx.doi.org/10.3329/jbau.v10i1.12037   J.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh during December 2015 to May 2016 to study the effect of age of seedlings at staggered transplanting and weed management on the growth and yield of aromatic Boro rice (cv. BRRI dhan50). The experiment comprised four seedling ages at staggered transplanting viz. 30, 45, 60 and 75-day old seedlings with five different weed management treatments viz. unweeded controls, two hand weeding at 20 and 35 DAT (days after transplanting), pre-emergence herbicide  (Pendimethaiin, Panida 33EC) applied at 3 DAT  + one hand weeding at 35 DAT, post-emergence herbicide (Penoxsulam, Granite 240 SC) applied at 12 DAT  + one hand weeding at 35 DAT, pre-emergence herbicide (Panida 33 EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT. It was observed that the experiment was laid out in a randomized complete block design with three replications. The highest plant height and total dry matter hill–1 were recorded in 30-day old seedlings with pre-emergence herbicide (Panida 33EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT. Younger seedlings (30-days old) produced the highest number of total tillers hill–1 (11.08), effective tillers hill–1 (8.47), grains panicle–1 (80.76) and grain yield (3.94 t ha–1) compared to aged seedlings at staggered transplanting. In case of weed management, pre-emergence herbicide (Panida 33EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT produced the highest number of effective tillers hill-1 (8.89), grains panicle–1 (81.66), 1000-grain weight (18.44 g), grain yield (4.47 t ha–1) and straw yield (5.13 t ha–1). Grain yield was reduced by 59.82% in unweeded control compared to pre-emergence herbicide (Panida 33EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT. In interaction, 30-day old seedlings combined with pre-emergence herbicide (Panida 33 EC) applied at 3 DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT produced the highest effective tillers hill–1 (9.58), grains panicle-1 (89.47), 1000-grain weight (18.93g), grain yield (5.31 t ha–1) and straw yield (5.75 t ha–1). Therefore, 60-day old seedlings at staggered transplanting with pre-emergence herbicide (Panida 33EC) applied at 3DAT + post-emergence herbicide (Granite 240 SC) applied at 12 DAT appears as the promising technique for aromatic Boro rice cultivation.J.

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
