Development of a low-cost ice crusher for raw fish storage
Abstract
Building a vertical farm in unused residential and commercial spaces is a challenge. It is particularly hard to decide upon a space where varying degrees of lighting conditions may prevail at different times of a day. This experiment was focused on how innovative micro-irrigation technology could be coupled with vertical farms. In this regard, three storied racks were designed to accommodate multiple one-feet-square tubs large enough to hold five Indian spinach (BARI Puishak- 2) plants at a time. Sandy loam soil was used for farming along with recommended doses of fertilizers. Different lighting conditions (2- 145 W/m2 average solar irradiance) were employed on the fifth floor of an urban building. Drip emitters were coupled in the system for irrigation. The management allowed deficit was kept to a maximum of 50% of the readily available moisture below the field capacity. The results suggested that drip irrigation systems provide higher water productivity (up to 31.82 kg/m3) compared to the in-field conditions when BARI Puishak-2 is grown in vertical farming. Water productivity of spinach was improved by optimized set-up of a drip irrigation system. The study also concluded that vertical farming is only suitable for indoor places where plenty of direct sunlight or diffused sunlight (not below 70 W/m2) is available. The economic analysis suggests that vertical farms under direct sunlight can be made profitable (BCR>1) in the long run.
Key Words: Micro-irrigation, BARI Puishak-2, Lighting conditions, Drip emitters, Vertical farming, Water productivity, Benefit Cost Ratio (BCR).

Physiological attributes of mungbean (Vigna radiata L.) influenced by different sources of nutrients (NPK) in Madhupur tract region of Bangladesh
Abstract
An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

Mechanization of fibre extraction: an eco-friendly alternative method of jute retting
Abstract
Jute retting has become a major obstacle for cultivation of jute due to water scarcity. Not only that, the water retting generates waste water and causes environmental pollution. This experiment was conducted to extract fibre through a mechanical process instead of extracting traditional water retting to overcome the problem. Machine extraction and water retting methods were applied on non-retted ribbons. Physico- chemical properties were then determined of the extracted fibre samples. The promising result obtained that the fibre extraction from ribbon is possible by the developed fibre extractor machine. Machine extracted fibre of the bottom portion shows similar strength and luster property like water retted fibre of the bottom. Middle portion of the machine extracted fibre showed a significantly higher luster property compared to water retted middle portion. Machine extracted fibres were coarse compared to water retted fibre. Water retting process produced finer quality fibre. Machine extracted fibres contain lower cellulose, higher hemicellulose and higher lignin compared to water retted fibre. These results show the possibility of developing alternative bast fibre extraction processes employing machine not undergoing water retting method.

Impact of different treatments on mat type seedling
Abstract
Since seedlings are raised throughout the chilly months of November and December, a cold mitigation technique at the seedling stage is a must during Boro season. This study was conducted at Agricultural and Bio-systems Engineering Lab under Farm Power and Machinery department at Sylhet Agricultural University during the 2018-19 academic year. The study aimed to evaluate the effect of biotic or abiotic factors that influenced seedling germination and growth during Boro season. With three replications, the experiment was done in a two-factor design. As abiotic stress control variables, a total of six treatments were taken under two different thicknesses (0.04 mm and 0.08 mm) of white polythene shed covering day time alone (12 hours) and day and night time (24 hours). To reduce biotic stress on early seedlings grown in plastic trays, two fungicides (Atavo and Autostin) and MoP fertilizer were employed in germination and rolling quality of seedling mat, seedling elevated plastic trays showed significantly superior results compared to the traditional method. In the uncovered tray, where no treatment was given, the fungal infection was severe. Seedlings that covered both thicknesses of polythene (0.04 mm and 0.08 mm) and prepared seed with both fungicides (Atavo and Autostin) exhibited significant resistance to fungal attack. Consequently, 0.08 mm thick white polythene as a covering mechanism and MoP as a treatment method was advised for seedlings growing in Sylhet's cold weather. Pre-treated seedlings with Autostin and the biotic stress management component fungicide Atavo recommended to avoid fungal infestation.
Key Words: Biotic stress, Fungicide, MoP, Germination, Rolling quality and Seed treatment.

Effect of seeding date on the tray raised seedling quality for rice transplanter in Boro season
Abstract
Mechanical rice transplanter needs a special type of seedling raised in-tray. Low temperature affected the quality of rice seedlings in Boro season. The purpose of this study was to find out the effect of seeding date on the properties of tray-type seedlings of three rice varieties namely BRRI dhan86, BRRI dhan89 and BRRI dhan92. This study was conducted in three locations namely Tangail, Rangpur and Gazipur in the Boro season of 2019-20. Four sowing date and three locations were considered and two factorial randomized completely block design (RCBD) with three replications was followed in the study. Characteristics of tray-raised rice seedlings suitable for mechanical transplanting in Boro season were revealed by this study. Seedling height and leaf number satisfied the requirement of transplanting. Seedling emergence was completed within 10 days after sowing (DAS). Seedling mortality of the tested three varieties started after 25 DAS in all locations. The seedling survival rate of BRRI dhan92, BRRI dhan89 and BRRI dhan86 exhibited the highest differently in a different location. The highest stem thickness of seedling was observed in all the tested varieties if seeds were sown on the 2nd and 3rd week of December in Gazipur and Rangpur location and 3rd and 4th week of December in Rangpur location. All the tested varieties showed a stem thickness of more than 1.5 mm. The highest stem strength was obtained if seeds were sown in the tray on the 3rd week of December. Variety showed inconsistent results on stem strength. The 2nd and 3rd week of December is an appropriate seeding time for optimum seedling height, stem strength and stem thickness in three locations. Seeding time affected the seedling emergence, mortality and height in the Boro season due to temperature variations and cold waves.
Key Words: Rice variety, seeding time, seedling emergence, stem thickness and stem strength.

The seedling survival rate of BRRI dhan92, BRRI dhan89 and BRRI dhan86 exhibited the highest differently in a different location. The highest stem thickness of seedling was observed in all the tested varieties if seeds were sown on the 2nd and 3rd week of December in Gazipur and Rangpur location and 3rd and 4th week of December in Rangpur location. All the tested varieties showed a stem thickness of more than 1.5 mm. The highest stem strength was obtained if seeds were sown in the tray on the 3rd week of December. Variety showed inconsistent results on stem strength. The 2nd and 3rd week of December is an appropriate seeding time for optimum seedling height, stem strength and stem thickness in three locations. Seeding time affected the seedling emergence, mortality and height in the Boro season due to temperature variations and cold waves.
Key Words: Rice variety, seeding time, seedling emergence, stem thickness and stem strength.
