Abstract:
The effect of artificial lighting in order to enhance day length for off-season dragon fruit production was examined for the first time in Bangladesh. A two factorial experiment was conducted at dragon fruit orchard of Agricultural Research Station, Pahartali, Khulshi, Chattogram to find out the best lighting duration and bulb for off-season dragon fruit production. Two factors were bulb and lighting duration for this experiment. The performance 6 hours lighting duration was significantly superior than other treatments in case of bud/pillar (43.80), fruit/pillar (43.80), fruit length (9.31 cm), fruit breadth (8.5 cm), individual fruit weight (344.62 g), yield (16.58 t/ha). 100 W IB having light intensity 225.96 lux showed superior performance over other treatments in case of bud/ pillar (49.44), fruit/pillar (34.56), fruit length (9.54), fruit weight (336.99 g), TSS (9.28%), yield (18.13 t/ha). The treatment combination (100 W IB for 6 hrs lighting) produced the highest number of fruit/ pillar (36.33), bud/pillar (54.00), fruit length (9.66 cm), fruit breadth (8.99 cm), yield/ pillar (12.41 kg) and yield (19.85 t/ha).In control dragon fruit was unable to produce flowering due to short day length. So artificial lighting of 6 hrs with 100 W IB from 18 pm to 24 am was superior method for off-season dragon fruit production.

Abstract:
Transplanted (T.) aman rice is the major crop in the southwestern coastal region of Bangladesh where most of the fields remain fallow the rest of the year due to the cultivation of late-maturing and long-duration aman rice varieties with low yield potential. Timely transplanting of short-duration HYV varieties increased grain yield and allowed the field to be cleared earlier for the next crop. The experiment was conducted in the experimental field of Agrotechnology Discipline, Khulna University, Khulna during the monsoon (June to December) for investigating the influence of transplanting dates on growth, yield attributes, and yield of Binadhan-7. The experiment was laid out in a randomized complete block design and replicated thrice. The experimental treatment comprised of ten transplanting dates (viz.,9 July, 16 July, 23 July, 30 July, 6 August, 13 August, 20 August, 27 August, 3 September, and 10 September) at 7 days intervals. Data recorded on different growth, yield, and yield contributing parameters were influenced substantially by the dates of transplanting. Results of this study showed that transplanting on 30 July produced the tallest plant (105.40 cm), highest tiller hill-1 (20.40), effective tillers hill-1 (17.30), panicle length (22.22 cm), number of grain panicle-1 (10.34), 1000 grain weight (22.83 g), grain yield (4.72 tha-1), straw yield (5.15 tha-1) and harvest index (47.85%) which were on parity with 6 August of transplanting. From the findings of this study, it can be concluded that from 30 July to 6 of August is optimum and recommended transplanting window for the short duration aman rice variety (Binadhan-7) in the coastal zone of southwestern Bangladesh. Furthermore, this transplanting window resulted in an early harvest and timely vacant the field for winter crop planting.

Abstract:
In Bangladesh, sesame (Sesamum indicum L.) production is attributed to low yield of the local cultivars with an indeterminate growth habit, uneven ripening of capsules, seed shattering, susceptibility to waterlogging and lack of adequate research findings. A field experiment was conducted in the Dr. Purnendu Gain Field Laboratory, Agrotechnology Discipline, Khulna University, Khulna to study the yield performance of some improved sesame varieties under rainfed conditions of Bangladesh. Six varieties of sesame viz. T6, Batiaghata local Til, Bina Til-1, BARI Til-2, BARI Til-3 and BARI Til-4 were evaluated in Randomized Complete Block Design (RCBD) with three replications. Data were collected on various yield parameters during harvest. Almost all the yield attributes were found higher in BARI Til-4 and Batiaghata Local Til except capsule length (BINA Til-1 possessed the longest capsules). These two varieties were recorded extra branches per plant (7.07 and 6.93), more number of capsules per plant (89.15 and 84.60), higher number of seeds per capsule (84.79 and 80.20) and higher harvest index (25.46 and 24.49%). The values mentioned in the parentheses did not differ significantly. As expected from the results, BARI Til-4 and Batiaghata Local Til produced statistically similar seed yields on unit area basis (1.29 and 1.13 t ha-1). Seed yield (g plant-1 as well as t ha-1) was well correlated with dry matter (g plant-1), biological yield (t ha-1) and harvest index (%) as revealed by simple regression analyses. Based on the findings of the study, the variety BARI Til-4 and Batiaghata Local Til may be recommended for cultivation in Khulna region under rainfed condition as it showed better performance in terms of yield parameters.

Abstract:
This literature review reports on risk factors for postpartum anoestrus in zebus and their potential treatments. Prolonged postpartum anestrus is one of the major factors limiting reproductive efficiency in cattle, particularly in Bos indicus cows in tropical regions, as it prevents a calving interval of 365 days from being achieved. During anestrus, ovulation does not occur despite ovarian follicular development, as the growing follicles do not reach maturity. This period is very variable and depends on various factors whose importance is relative or, on the contrary, essential. Some are specific to the animal (breastfeeding or food); others relate more to its social environment, season sanitary conditions. Several hormonal treatments have been used to induce ovulation and cyclicity in postpartum cows. Generally speaking, given the inconsistency of the effects or even their lack of practicability, treatments using a single or repeated injection of a gonadotropin-releasing hormone (GnRH) have been gradually abandoned in favour of progestagens. These are administered for 8 to 12 days on a continuous basis in the form of a subcutaneous implant (Crestar®), a vaginal coil (PRID®) or a CIDR. A prostaglandin injection is given two days before the implant is removed. The addition of an ECG treatment at the time of device removal, which increased plasma progesterone concentrations and pregnancy rates in anestrous postpartum suckled Bos indicus cows, may be useful to improve reproductive performance. This improvement requires a better understanding of the effect of different risk factors on the recovery of postpartum cyclicity.

Abstract:
We review edible mushrooms in South Korea, primarily focused on oyster mushroom (OM) (Pleurotus ostreatus), which shows the highest production among the mushrooms grown for industrial purposes, and it takes up almost 32% of the total production. We aimed to describe their historical uses, common cultivars, and specific characteristics that make them one of the most viable food sources or functional materials. About 15,000 mushroom varieties are known, and 2,000 varieties are possible as human food. Generally, OM has long been studied the most widely as an edible mushroom compared to the other mushrooms in South Korea. Recently, there has been a growing interest in food mushrooms as the production of O.M. is characterized by low greenhouse gas emissions compared to animal breeding in South Korea. Also, OM is often highlighted as nutritious side dishes to serve with rice. Thus, facilitating O.M. production and consumption could contribute to human health and environmental conservation in the near future. Over the years 2015–2020, Pleurotus sajor (PS) export increased by 189.9% (US$ 130,000) compared to 2010-2015. The O.M. cultivation tends to increase rapidly in developing countries for human food and compost or insect foods after cultivation, for example, internal use of culture media or sawdust dump of willow growing environmental conditions. In South Korea, mushroom research has started in the 1960s by the horticultural research center of Rural Development of Administration. In the early 1970s, OM cultivation methods using paddy straw were first developed globally. In 1974, NONGGI-2-1-ho cultivar was developed. In 1976, various practices for water management, disinfection, and fermentation were developed, resulting in substantial yield increases. From 1986, labor-saving paddy straw binders, cutting machines, disinfection boilers, wager suppliers were produced and started being supplied to the farmers. In the 1980s, cotton waste was used as a substrate for cultivation of OM, where water content was identified as the dominant controlling factor for yields. Cotton waste is the best substrate material for summer OM. After using cotton waste, it is commonly replaced with paddy straw. Recently, growers use poplar sawdust, oak sawdust, and rice bran mixed at a ratio of 40:40:20 (v/v/v) instead of cotton waste. When adjusting the nutrients of a medium, the nitrogen content is the crucial factor in determining the yield of OM. There is an additional attempt to add functionality by using alternative plant materials, such as Hovenia dulcis known for liver protection and anti-cancer effects, as well as Acer tegmeutosum and Rhus verniciflura. Further research is in progress to search for and new medium materials effective for OM cultivation.

Abstract:
The experiment was conducted at the Horticulture farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka-1207 during the period of November 2019 – May 2020 to find out Influence of bio-fertilizer application method with organic and in-organic fertilizer on growth and yield of bitter-gourd in winter season .The experiment was consisted of two factors : as- Factor A: Fertilizer (4 levels) T0: control, no fertilizer ,T1: Organic (kitchen compost @1000 kg/ha),T2: in-organic (N46 P40 K 45 ) Kg/ha and T3: Organic (kitchen compost @1000 kg/ha) + in-organic (N23 P20 K23) kg/ha Factors B: Bio-fertilizer application method (3 levels) F1: Seed treatment with bio-fertilizer @ 100ml/250g seed,F2: Seedling treatment with bio-fertilizer @400 ml/500 seedling. And F3: Soil treatment with bio-fertilizer @.046 g/m2. The two factorial experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Maximum plant height (299.69 cm),fruit number per plant (19.96), fruit length(27.11 cm), yield/plant (1.05 kg), yield per plot(6.30kg) and total yield (19.44 t/ha) were found from T3F3 treatment. whereas minimum plant height (90.67 cm), fruit number per plant (1.27), fruit length (4.49 cm), yield/plant (.046 kg), yield per plot(.28 kg) and total yield (.86 t/ha) were found from T0F2(control) treatment .All growth related parameter was collected up to 75 DAS due to COVID-19.This study suggests that T3F3 (Organic (kitchen compost @1000 kg/ha) + in-organic (N23 P20 K23) kg/ha)+ bio-fertilizer (soil treatment) treatment acts as a potential source of plant nutrients for suitable bitter gourd production. The combination of organic, In-organic and soil application of bio-fertilizer (T3F3) gave the highest gross return (Tk. 1458000). The lowest gross return (Tk.85600) was obtained in the control condition where no bio-fertilizer as well as no fertilizer was applied. The combination of organic, inorganic and soil application of bio-fertilizer (T3F3) gave highest benefit cost ratio (3.16) and the lowest benefit cost ratio (0.60) was obtained in combination of control condition (T0F2). So, the economic analysis revealed that the treatment T3F3 combination appeared to be the best for achieving the higher growth, yield and economic benefit of bitter gourd.

Abstract:
Two consecutive field experiments were conducted at the Suapur Union of Dhamrai Upazila, Dhaka, is located at 23088´N latitude and 90014´E longitude and AEZ-12, Bangladesh. The purpose of the experiment was to study the combine effect of nitrogen application methods and weed management for maximizing yield and yield components of boro rice (cv.BRRI dhan29).The experiment consisted of four nitrogen management methods and four weed managements. The experiment comprised two factors; Factor A: Nitrogen management (4 levels), N0: No urea (control), N1: Urea super granules-USG (77 kg N ha-1), N2: Prilled urea at recommended dose (150 kg N ha-1) and N3: ½ of the recommended dose (75 kg N ha-1); Factor B: Weed management (4 levels), W0: No weeding (control), W1: Two hand weeding (20 and 40 DAT), W2: Pre emergence herbicide (Butachor) and W3: Post emergence herbicide (Prityloclor). The experiment was laid out in a randomized complete block design with three replications. Data on different yield components and yield of BRRI dhan29 were recorded. Statistically significant variation was observed for their combined effect. The highest grain yield (6.80 t ha-1) was obtained from the interaction between urea super granules-USG (77 kg N ha-1) and pre emergence herbicide (Butachor), whereas whereas the lowest (3.85 t ha-1) from the interaction between no urea (control) and no weeding (control). From the results of the study it can be concluded that the application of urea super granules-USG (77 kg N ha-1) and pre emergence herbicide (Butachor) condition might be used for obtaining the best performance of BRRI dhan29.

Abstract:
This study was conducted at the tissue culture laboratory in Pakistan. Suckers obtained from the banana cv. Grand Nain to explore the effects of different concentrations of BAP and IAA. After inoculation with Murashige and Skoog (MS) medium supplemented with different concentrations of 6-Benzylaminopurine (BAP) and the Indole-3- acetic acid (IAA) the suckers first turn into the brown after 5-10 days then turned into a green mass-like structure after 30 days. From this mass-like structure shoots and roots were developed. Among the different concentrations, BAP 7.5 mg/l and IAA 0.5 mg/l showed the highest number of shoots 0.75, 2.75 and 6.25 per explant and shows the highest shoot lengths which 1.03 cm, 2.45 cm and 3.40 cm respectively. IAA is essential for only roots proliferation. The roots of different lengths were produced when the concentration of IAA 0.5 mg/l was used and 2.93 cm, 4.63 cm and 5.88 cm roots length produced at 15, 30 and 45 days after occultation respectively. Then these plants were transferred to the greenhouse for hardening acclimatization with the environment, the hardening process took place, and the established plantlets are ready for planting.
