Poor seedling establishment and seedling mortality is the major barrier to optimum stand establishment in dry direct seeded boro rice. Experiments were carried out at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh, Bangladesh during January to June 2013 to study the effect of Trichoderma and fungicide application on seedling establishment and yield performance of dry direct seeded Boro rice. The experiment comprised ten treatment combinations of Trichoderma and fungicides viz. seed treatment with Trichoderma (M1), seed treatment with Trichoderma+spraying of Thiovit (M2), seed treatment with Trichoderma + spraying of Propiconazole (M3), seed treatment with Trichoderma + spraying of Thiovit and Propiconazole (M4), spraying of Thiovit (M5), spraying of Propiconazole (M6), seed treatment with Thiovit + spraying of Propiconazole (M7), seed treatment with Propiconazole + spraying of Thiovit (M8), spraying of mixture of Thiovit and Propiconazole (M9), and control (no fungicide or Trichoderma ) (M10).The experiments used Randomized Complete Block Design (RCBD) with three replications. Experiment revealed that seed treatment with Trichoderma harzianum followed by spraying of Thiovit gave the highest yield of rice. The study concludes that Trichoderma and then application of sulphur fungicide at 20 days after sowing could be practiced for ensuring high seedling establishment and yield of rice under dry direct seeded system in boro season.J.

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 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.

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 conducted at Khitrokashipur, Durgapur, Rajshahi during March to June 2018 to study the effect of organic amendment on soil quality and yield performance of dry direct seeded boro rice var. BRRI dhan28. The treatments were Trichocompost (TC), Vermicompost (VC), mustard oil cake (MOC), Trichocompost + mustard oil cake (TC+MOC), Vermicompost + mustard oil cake (VC + MOC), and no amendment control. The experiment was laid out in a randomized complete block design with three replications. Trichocompost and Vermicompost were applied @ 3 t ha-1, while mustard oil cake was used @ 0.5 t ha-1. The results revealed that Trichocompost and vermicompost fertilization exerted significant influence on yield performance of BRRI dhan28 in boro season. The treatment trichocompost (T1) @ 5 t ha-1 produced the highest grain yield (5.95 t ha-1), while the mustard oil cake (T3) @ 0.5 t ha-1 the highest effective tillers hill-1 (15.33), though  the highest straw yield (5.46 t ha-1) was produced in the treatment VC + MOC (T5). In case of soil properties, Trichocompost (T1) @ 3 t ha-1 and mustard oil cake (T3) @ 0.5 t ha-1 improved soil organic matter content, while Trichocompost (T1) @ 3 t ha-1 and Vermicompost (T2) @ 0.5 t ha-1 improved phosphorus and potassium content. Field capacity was greatly influenced by Trichocompost (T1) @ 3 t ha-1 and Vermicompost + mustard oil cake (T5). Soils with Trichocompost (T1) @ 3 tha-1 showed the highest bulk density. It was concluded that organic amendment greatly improved the yield performance of BRRI dhan28 and also soil physical and chemical properties under dry direct seeded boro rice cultivation system.

This study evaluates the growth performance of lettuce (Lactuca sativa L.) utilizing various fermented products as organic fertilizers. Growth performance is determined through the plant’s weight and leaves and significant differences in growth among various treatments: (a) fish trash, (b) scrap seaweeds, (c) kangkong, and control groups urea (positive) and water (negative) was also determined. Kangkong leaves are fermented for 10 days, fish trash for 14 days and 1 month for seaweeds. Lettuce seeds are sown before transplanting (15 days after germination) into pots and placed in raised beds. Randomized complete block design is utilized in the experiment. Growth performance is measured through the number of leaves 10, 20, and 30 days after transplant and mass of plant upon harvest. After 30 days, the lettuce was harvested. Based on the findings, the soil and fermented products are acidic and the needed organic matter for optimum growth of lettuce are not sufficient as well as some nutrients of the fermented products. Among the organic fertilizers, kangkong at 30 ml performs best in terms of the growth performance of lettuce. Urea performs best in terms of the mass upon harvest. Significant differences exist in the mean number of leaves of lettuce treated with various amounts of organic fertilizers with the plants that receive urea. Lettuce produce more number of leaves and with the highest mass upon harvest when treated with urea compared with organic fertilizers applied after 30 days from transplant.

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.

Untreated Check

Curly top in sugar beet caused by Beet curly top virus (BCTV) is an important yield-limiting disease that can be reduced via neonicotinoid and pyrethroid insecticides. The length of efficacy of these insecticides is poorly understood; therefore, field experiments were conducted with the seed treatment Poncho Beta (clothianidin at 60 g a.i. + beta-cyfluthrin at 8 g a.i. per 100,000 seed) and foliar treatment Asana (esfenvalerate at 55.48 g a.i./ha). A series of four experiments at different locations in the same field were conducted in 2014 and repeated in a neighboring field in 2015, with four treatments (untreated check, Poncho Beta, Asana, and Poncho Beta + Asana) which were arranged in a randomized complete block design with eight replications. To evaluate efficacy, viruliferous (contain BCTV strains) beet leafhoppers were released 8, 9, 10, or 11weeks after planting for each experiment, which corresponded to 1, 2, 3, and 4 weeks after Asana application. Over both years, in 30 of 32 observation dates for treatments with Poncho Beta and 14 of 16 observation dates for Asana, visual curly top ratings decreased an average of 41 and 24%, respectively, with insecticide treatments compared with the untreated check. Over both years, in eight of eight experiments for treatments with Poncho Beta and six of eight experiments for Asana, root yields increased an average of 39 and 32%, respectively, with treatment compared with the untreated check. Over both years, the Poncho Beta treatments increased estimated recoverable sucrose (ERS) yield by 75% compared with the untreated check for weeks 8 and 9. By week 10, only the Poncho Beta + Asana treatment led to increases in ERS in both years, while the influence of increasing host resistance may have made other treatments more difficult to separate. When considering curly top symptoms, root yield, and ERS among all weeks and years, there was a tendency for the insecticides in the Poncho Beta + Asana treatment to complement each other to improve efficacy.

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

Abstract Common weaning practices in today’s beef industry involve discontinuation of the cow-calf social and nutritional bond. When this bond is discontinued, atypical behaviors of walking and vocalizing are immediately observed in the calf that negatively affect calf welfare. Global positioning systems (GPS) provide an opportunity to quantify the effects of animal activity on welfare. Utilizing GPS technology, we are able to determine total distance walked, speed, total time walking, or total time not walking and the interactions with calf production. Thus, the objective of the present study was to evaluate the effects of a familiar trainer animal on calf production during weaning and more specifically, common weaning behaviors such as walking utilizing a Garmin® product. A total of 80 Angus x Simmental heifer calves were used in this study. In all four replications, heifer calves were allotted to each treatment group (n = 10), trainer animal or control (TR, CON) on the day of weaning. Calves in the TR group were placed on pasture at weaning with the familiar trainer animal, and control calves were placed in a similar size pasture without a trainer animal. Each calf was also fitted with their own GPS collar that recorded on days 0, 7, and 14 relative to initiation of the study for a full 24 hours before removal. Data were analyzed as a randomized complete block design with repeated measurements (SAS 9.4). Placing calves with a familiar trainer animal decreased the distance calves walked (P = 0.001) as well as the amount of time calves were walking (P = 0.001). Placing a familiar trainer animal with calves at weaning, therefore, has an effect on walking distance and amount of time calves devote to walking.

Abstract One of the factors limiting crop growth is weeds. The weeds lead to a reduced performance of the crops. Chemical control methods are considered appropriate for controlling weeds. Therefore, in the fight to control weeds in triticale, the performance of the dual-purpose herbicide sulfosulfuron(Apirus®), mesosulfuron + idosulfuron(Atlantis®), metsulfuron methyl+sulfosulfuron(Total®) with surfactant and isoproton + diflufenican(Panther®) from the sulfonylurea group, and narrow leaf herbicides clodinafobpropargyl( Topik®), pinoxaden(New Axial®), diclofop-methyl(Iloxan®), pinoxaden + clodinafob-propagyl (Traxos ®), fenoxaprop-pethyl + mefen-pyper-d-ethyl(PumaSuper®), tralkoksidim(Grasb®) with 1 liter oil, flam-prop-m-isopropyl(Suffix BW®), and control treatment without herbicides were evaluated. The test was carried out in a randomized complete block design with four replications. Spraying was carried out using a back sprayer. For evaluation of ocular damage, the European Weed Research Council (EWRC) standard method was used. According to the performed studies, the narrow leaves of wild oat and barnyard grass were the dominant weeds. Results showed that all herbicide, except the herbicide tralkoksidim, were effective in weed control. The triticale yield was maintained with the use of these herbicides and none of herbicide had an adverse effect on the crop. In the first weeks of herbicide use, the triticale leaves appeared pale but this problem resolved over time. It seems that the herbicides discussed in this paper can be used on the triticale plant.
