Pesticides have been used to treat agricultural lands since ancient times. The effects of an organophosphate (OP) and pyrethroid combination on the haemato-biochemical and histological functions of male albino rats were investigated. Male albino rats (total 18 rats, 12 are treated and 6 are control) were dermally treated with two organophosphate and pyrethroid combinations for 8 weeks (chlorpyrifos, chlorpyrifos-methyl, and lambda-cyhalothrin). We also looked at organ weights, haematological and histological changes, and clinical symptoms. Except for RBCs, total protein, and haemoglobin, all haematological measures rose in treated rats after 8 weeks. After 4 weeks, Runsave and Lambaphos treatments had RBC counts of 5.02 and 5.15 106/mm3, respectively, compared to 6.1 106/mm3 in the control group. Haemoglobin values for Runsave, Lambaphos, chlorpyrifos, chlorpyrifosmethyl, and lambda-cyhalothrin were 13.53, 14.27, 14.60, 15.03, and 15.27 g/100 ml after toxicant administration, compared to 16.53 in the control. Haematological parameters change correlated positively with exposure time. A histological examination on liver and kidney found that Runsavetreated rats had an uneven structure, severely congested blood arteries, necrotic areas, fatty liver, pyknotic nuclei, and cytoplasmic vacuolation in hepatic cells. Lambaphos-treated liver shows haemolysis, cytoplasmic vacuolation, pyknotic nuclei, and partial structural disruption. Bowman's capsule, glomeruli, and proximal tubule are normal in the control kidney. Runsave had abnormal renal anatomy. Lambaphos kidneys are asymmetrical. This study demonstrated that albino rats subjected to an insecticide mixture of organophosphate and pyrethroid had significant histological and haematobiochemical changes compared to the control group.

The experiment was carried out at Agricultural Research Field, Noakhali Science and Technology University, Noakhali, Bangladesh during the period of March to June 2021, to evaluate the growth and yield of cucumber (Cucumis sativus L. CV: MOHABIR) as influenced by different levels of NPK fertilizer. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatments were T0 (no NPK), T1 (N 69 kg ha-1, P2O5 48 kg ha-1 and K2O 75 kg ha-1), T2 (N 69 kg ha-1, P2O5 60 kg ha-1 and K2O 90 kg ha-1), T3 (N 92 kg ha-1, P2O5 72 kg ha-1 and K2O 105 kg ha-1), respectively. Data were recorded from different stages of plant growth on the number of leaves per plant, number of fruits per plant, fruit length, fruit diameter, individual fruit weight, yield per plant and yield per plot. All the recorded parameters were statistically significant (p<0.01). The maximum number of leaves per plant (37.83) was recorded from T3 (N 92 kg ha-1, P2O5 72 kg ha-1 and K2O 105 kg ha-1) whereas the minimum number of leaves per plant (27.92) was obtained from the control T0 (no NPK). Highest number of fruits per plant (11.92), fruit length (16.00 cm), fruit diameter ((4.10 cm), individual fruit weight (167.17 g), weight of fruits per plant (2.00 kg), and yield per hectare (68.35 t/ha) was found in treatment T3 (N 92 kg ha-1, P2O5 72 kg ha-1 and K2O 105 kg ha-1) whereas lowest data recorded from control T0 (no NPK). Observing the results, it can be stated that application of NPK fertilizer @ N 92 kg ha-1, P2O5 72 kg ha-1 and K2O 105 kg ha-1 for cucumber cultivation gave better growth and yield in the coastal region of Bangladesh.

Pre extension demonstration of food barley varieties was carried out during 2010/11 and 2011/12 E.C cropping season with the objective of evaluating the best performed and preferred food barley varieties under farmer’s management condition. The trial was carried out selecting one kebele from each Anfilo, Hawa Gelan and Boji Dirmaji districts and selecting two kebeles from Seyo district. Three improved varieties of food barley (dinsho, abdane and biftu) with a local check were evaluated with full participation of FRG members under their management condition. The best fit variety was selected with the participants. The total of five (5) FRGs which incorporated a total of 59 male and 23 female was established. Each experimental plot had gross area of 100 m2 and rows spacing of 25 cm were used. All recommended agronomic practices were equally applied to all plots. Yield of varieties were collected and analyzed using descriptive statistics. Accordingly the yield performances of varieties were 28.66 qt/ha, 26.02 qt/ha, 23.96 qt/ha and 21.15 qt/ha for Dinsho, Abdane, Biftu and local respectively. Accordingly, the yield advantage of dinsho over local is 35.5% while the yield advantage of abdane over local is 23.02% and yield advantage of biftu over local is 13.28%. Farmers were enhanced to evaluate the technology using their own criteria. Accordingly they selected dinsho variety as their first choice by its grain yield, disease resistance, finger size and abdane variety secondly by its merits of early maturity, lodging tolerance and biftu and local thirdly and fourthly respectively. Generally based on farmer’s preference and objectively measured trait variety dinsho should be scaled up/out in Sayo, Hawa Galan, Anfilo and Bodji Dirmaji districts and similar agro ecology of West and Kellam wollega zones.

An experiment was conducted at Bangabandhu Academy for Poverty Alleviation and Rural Development (BAPARD) Agricultural Farm, Kotalipara, Gopalganj during December, 2019 to May, 2020 to find out the vegetative growth and yield performance of three BARI tomato varieties viz. BARI Tomato-11, BARI Tomato-14 and BARI Tomato-15. The plant height of BARI Tomato- 11,BARI Tomato-14, BARI Tomato-15 were 8.21cm, 7.17cm, 8.82cm, 8.73cm, 7.75cm, 9.37cm, 15.40cm, 13.24cm, 14.40cm respectively at 0 DAT, 10 DAT, 20 DAT with significantly increase 20 DAT except 0 DAT and 10 DAT. First flowering of BARI Tomato-11, BARI Tomato-14 and BARI Tomato-15 was 39 DAT, 40 DAT and 41 DAT which was statistically identical. Number of fruits per plant and weight of individual fruit of BARI Tomato-11, BARI Tomato-14, BARI Tomato-15 were 142.96, 34.92, 30.95 and 10.85gm, 78.5gm, 59.9gm respectively. In case of number of fruits per plant, BARI Tomato-11 showed the maximum but weight of individual fruit was very low because of size and shape was very small. Fruit yield of BARI Tomato-11, BARI Tomato-14 and BARI Tomato-15 were51.67 t/ha, 91.33 t/ha and 61.67 t/ha, respectively. The present study concluded that BARI Tomato-14 is more suitable for this area. Res. Agric., Livest. Fish.9(1): 37-42, April 2022

Marine fishes are currently experiencing population decline which has severe repercussions on food security, especially in fishing households. However, without assessing the distribution and abundance of these marine fishes, ensuring sustainable management will become impossible. Therefore, the study aimed at applying multivariate techniques to determine the biodiversity of fishes along the coast of Ahanta West, Ghana. Fish samples were collected daily through experimental fishing from November-December, 2011. Data obtained from the study were analyzed for ecological indices, species diversity, and community structure using PAST and PRIMER v6 software. From the results, Pteroscion peli (19.2%), Galeoides decadactylus (11.7%), and Brachydeuterus auritus (9.0%) were the dominant fishes. Multivariate analysis identified three main assemblages of fishes, at 18%. For the ecological indices, the species dominance index (SDI) ranged from 0.89 to 0.93, which indicated that the fish species were highly dominated by a few species. The Shannon Weiner index (SWI) and Species Richness index (SRI) spanned between 2.64 – 2.92 and 4.43 – 648 respectively, showing high diversity of fish species. It is concluded that the marine environment along the Ahanta West, Ghana is rich in fish species diversity, and hence, there is the need to regulate existing fishing operations for sustainable utilization and conservation of these commercially important fish species.

Roselle (Hibiscus sabdariffa var. sabdariffa) is an annual subshrub, and its leaves, seeds, and especially calyces are valued for their nutritional and medicinal uses. The objectives of the study were to evaluate the best one among three morphotypes of Roselle. The morphotypes of Roselle were green plant with green calyx (WC); light red plant with light red calyx (LRC); and deep red plant with deep red calyx (DRC). The field experiment was laid out in Randomized Complete Block Design (RBCD) with three replications. Several morphological characteristics include plant height, stem base diameter, number of branches per plant, total fresh and dry biomass yield, number of capsules per plant, the weight of capsule per plant, weight of fresh calyx per plant, weight of dry calyx per plant, shelling ratio (%), etc. were evaluated. Significant differences were observed in morpho-agronomic characters in these three morphotypes. The DRC demonstrated the greatest performance across morphotypes for the number of capsules per plant (343.33), the weight of fresh capsules per plant (2227.77g), and shelling ratio (% calyx to capsule) (43.03 %). And LRC morphotype had the best performance in plant height (114.00 cm) and stem base diameter (4.30 cm). In general, the DRC morphotype outperformed the WC and LRC morphotypes. Res. Agric., Livest.

The goal of this study was to determine the frequency of surgical affections and their associated risk factors in new born calves from the Mollahat, Fakhirhat, and Bagerhat Sadar upazilas of Bagerhat district. From 2015 to 2019, 5238 retrospective data were collected in all three upazilas. The surgical affections were categorized on the basis of sex and breed. The highest number of surgical affections found in all three upazila was navel ill with myiasis (60.44% in Mollahat upazila, 71.43% in Fakhirhat upazila and 60.11% in Bagerhat Sadar upazila). Surgical affections in calves vary in frequency according to the animal's sex and breed. Among the affections, navel ill with myiasis was higher (66.67% and 71.43%) in male than female calves (33.33% and 28.57%) in Mollahat and Fakhirhat upazila, respectively. However, in Bagerhat Sadar upazila congenital cataract was higher (71.43%) in male calves compared to female (28.57%). According to the breed, navel ill with myiasis were higher (64.85%) followed by umbilical hernia (18.74%) in cross breed calves. While navel ill with myiasis were higher (56.01%) followed by abscess (15.93%) in indigenous breed calves. According to the study, environmental conditions or management techniques can trigger surgical affections. It will be feasible to identify the prevalence of various surgical illnesses in this sector based on sex and breed based on the outcomes of this study in order to combat these diseases. Res.

Photoperiod response to flowering is one of the most vital factors that affect in regional adaptation and yield in soybean. Soybean adaption at high latitude areas (long-day) requires early flowering and low photoperiod sensitive cultivars; adaptation to low latitudes (short-day) areas needs delayed flowering cultivars, which maximize vegetative growth and seed yield. This paper represents a genetic and molecular regulation of flowering time in soybean, which will help broad adaptability across latitudes. It is revealed that one to eleven main genes control the flowering time in soybean. The FT family of flowering integrators plays a central role in controlling the flowering time. The juvenile growth phase (JGP) determines the development rate for flowering; a long JGP results in the lengthening of the vegetative period and increases the soybean production in low latitude areas. This review outlines the JGP-related gene in soybean. We emphasize the interaction between major genes and QTLs for flowering in soybean. Several major genes and quantitative trait loci (QTLs) for flowering interact with one another including the environment to greatly influence flowering time. The molecular ground information of the flowering in Arabidopsis will help to understand the molecular dissection of flowering in soybean. This information could be used for breeding of high‐yielding soybean cultivars in different latitudinal areas. Res. Agric., Livest. Fish.9(1): 1-10, April 2022

Pre extension demonstration of improved field pea varieties was conducted in Goba, Sinana and Agarfa districts of Bale zone. The main objective of the study was to demonstrate and evaluate recently released (Weyib) variety along with standard check. The demonstration was under taken on single plot of 10mx10m area for each variety with the spacing of 30cm between rows and recommended seed rate of 75kg/ha and fertilizer rate of 100kg/ha NPS. Mini-field day involving different stakeholders was organized at each respective site. Yield data per plot was recorded and analysed using descriptive statistics, while farmers’ preference to the demonstrated varieties was identified using focused group discussion and summarized using pair wise ranking methods. The demonstration result revealed that Weyib variety performed better than the standard check (Tulu shanan variety) with an average yield of 34.47qt/ha, while that of the standard check was27.26qt/ha. Weyib variety had 17.27% yield advantage over the standard check. Thus, Weyib variety was recommended for further scaling up. Res. Agric., Livest. Fish.8(3): 267-271, December 2021

Two types of fodder crops were evaluated in this study, maize (Zia maize) and black gram (BG) (Vigna mungo) and in maize, non-descriptive local maize (LM) and hybrid maize (HM) verity were used. LM was considered as control and changes of the nutritional composition according to the type of fodder (leguminous and non-leguminous) and the day was evaluated. For comparative nutritional analysis, dry matter (DM), crude protein (CP), ether extract (EE), crude fibre (CF), acid detergent fibre (ADF), neutral detergent fibre (NDF), and total ash were analyzed and the biomass yield was measured using weight balance and root and shoot length of experimental fodders. Results revealed that among three types of forages total DM was significantly (P<0.01) higher in HM and significantly (P<0.01) lower in BG. Considering total CP and NDF, it was significantly (P<0.01) higher in BG and HM than LM. The highest biomass yield and shoot length were observed in BG and the lowest biomass yield was observed in HM. Moreover, with the increment of days, all fodder sprouts DM% was constantly decreasing, however, CP% maintained the same level from day 1 to 5. Although from day 6 to 9, CP% increased moderately for HM and BG, CP% decreased slightly for LM. Therefore, farmer can use BG and HM for maximum utilization of nutrients and considering DM and CP% for LM day 6 was the best time for harvesting; however, for HM and BG, day 9 or more than 9 was the best time for harvesting.
