Effects of nitrogen and phosphorus fertilizer on yield and yield attributes of lettuce (Lactuca sativa L.)
Abstract
An experiment was conducted to assess the effects of different nitrogen and phosphorus fertilizers applied alone or combined with on lettuce plant yield during the period 2011. The experiment considered two factors; viz. Factor A: four levels of nitrogen kg/ha (0, 110, 160 and 210); and Factor B: four levels phosphorus kg/ha (0, 110, 160 and 210). The experiment was laid out in randomized complete block design (RCBD) with three replications. Data on yield and yield attributes of lettuce were collected at different days after transplanting and green yield of lettuce were collected at harvesting time. At 55 DAT (at harvest) the longest plant height (27.76 cm), leaf yield per plant (393.28 g), yield per hectare (39.39 t/ha), was recorded from N3 (210 kg/ha) and the shortest plant height (23.14 cm), leaf yield per plant (314.67 g), yield per hectare (31.51 t/ha), was recorded from control whereas the maximum (31.30) number of leaves per plant was recorded from N2 (160 kg/ha). At harvest the longest (27.88 cm) plant height, number of leaves per plant (31.74), leaf yield per plant (385.35 g), yield per hectare (38.57 t/ha) was observed in P3 (210 kg/ha) and the shortest plant height (22.87 cm), the minimum number of leaves (24.61), yield per plant (320.86 g), yield per hectare (31.09 t/ha) observed from control. Among different treatment combinations N2P3 (160 kg N/ha +125 kg P/ha) performed the highest (38.09 t/ha) yield. So N2P3 was the suitable combination for lettuce production than those of others. The highest (2.24) benefit cost ratio was performed from the treatment combination of N2P3 (160 kg N/ha +125 kg P/ha) and the lowest benefit cost ratio (1.46) was obtained from control treatment. The study found that the higher yield and economic return of lettuce production could be obtained by cultivating the crop with 160 kg N/ha and 125 kg P/ha.The results indicated that application of urea-formaldehyde as a slow release nitrogen fertilizer solely or combined with phosphorus significantly improved yield and yield quality of lettuce plants grown in Bangladesh.

Effect of ethephon on post-harvest characteristics of kiwi (Actinidia deliciosa cv. Monty) in Dolakha, Nepal
Abstract
An experiment was conducted in laboratory of Rural Development Tuki Association, Dolakha in 2019 to study the effect of ethephon on post-harvest characteristics of kiwifruit and identify appropriate concentration required for timely ripening of kiwis. Monty variety of kiwi was used under study. The experiment was laid out in Completely Randomized Design (CRD) with five treatments having different concentration of ethephon i.e. T1 = Control, T2 = 100 ppm, T3 = 300 ppm, T4 =500 ppm and T5 = 700 ppm, each replicated four times. The study showed that maximum TSS (16.630brix) was observed in the fruits treated with 700 ppm at the end of ripening period which was statistically at par with 500 ppm whereas minimum TSS (12.00brix) was observed in control fruits during 30th day after treatment. At the peak period of ripening, fruits treated with 700 ppm led to lowest titratable acidity (0.66%), maximum TSS/TA (25.57), maximum physiological weight loss(17.28%) and highest Ph(4.08) whereas Control fruits showed maximum acid content (1.1%), minimum TSS/TA(12.1), lowest physiological weight loss ( 11.8%) and lowest Ph (3.5) during 3oth day of treatment. The storage life of fruits treated with 700 ppm was minimum (16.25 days) followed by 500 ppm (22.13 days) which was maximum (48.25 days) in case of control fruits. Eating quality declined significantly in highest dose (700ppm) of ethephon at the end of ripening period and in this stage, 500 ppm ethephon developed very good edible quality (2.75) followed by 300 ppm (2.25). In a nutshell, considering the post-harvest life and quality attributes, the concentration of ethephon ranging from (500-700) ppm was found appropriate for timely ripening of kiwi.

Allelopathic effects of Eucalyptus camaldulensis on germination and seedling growth of mungbean
Abstract
The term of allelopathy, whereby one plant chemically interferes with seed germination, growth and development of others has been documented for over 2000 years. Allelochemicals are secondary metabolites of plants, released into the nearby environment through volatilization, leaching, root exudation and decomposition of residues. This experiment was aimed to examine the allelopathic effect of aqueous extracts of Eucalyptus leaves on seed germination and early growth of mungbean. Two pot experiments were carried out at Agronomy laboratory and research field, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur during February 2017 to March 2017 to find out the response of mungbean variety on Eucalyptus camaldulensis leaf extract. For screening four mungbean varieties (BARI Mung-3, BARI Mung-4, BARI Mung- 5 and BARI Mung-6) were tested with five levels of Eucalyptus camaldulensis leaf extract as allelopathic chemical (0, 5, 10, 15 and 20% concentration) for 8 DAS in small plastic pot. The germination rate of mungbean varieties was delayed and germination percentage was reduced with increasing leaf extract concentration compared to control. Fresh and dry weight of seedling was also lessened significantly compared to control. The inhibitory effects of Eucalyptus leaves were augmented as the extract concentration increased. These findings revealed that eucalyptus leaf extract adversely affect the germination and seedling growth of mungbean.

A comparison between synthetic wheat derivatives and bread wheat (Triticum aestivum) at seedling stage under various levels of temperature and GA3 priming
Abstract
In upcoming years, global warming could produce alarming situation for wheat. Yield and maturity of wheat are critically determined by seedling vigor, with temperature as modifying factor. For the same reason, it is required to determine the adaptation of bread wheat (B) and synthetic wheat derivative (SD) at seedling stage under the influence of temperature fluctuation. The study was conducted to compare synthetic wheat derivative (SD) with bread wheat (B) at low temperature (10°C), moderate temperature (22°C) and high temperature (35°C) with and without gibberellic acid (GA3) priming at seedling stage. The plant material consisted of four wheat genotypes, two bread and two synthetic wheat derivatives. Following plant parameters were studied viz. germination percentage (G%), germination index (GI), root length (RL), coleoptile length (CL), shoot length (SL) and seed vigor index (SVI). Analysis of variance revealed significant effect of different levels of temperature on wheat genotypes. After making comparison between bread and synthetic wheat derivatives genotypes for all the parameters, results were significantly in favour of SD. Synthetic wheat derivatives obtained relatively higher values of G%, GI and CL at low temperature and G%, GI, SVI, CL, SL and RL at high temperature than bread wheat. High temperature combined with GA3 priming showed zero results in all genotypes due to GA3 inactivation at high temperature. These results indicate that synthetic wheat derivatives can perform better relatively than bread wheat at seedling stage, under the influence of temperature fluctuation.

Growth performance of some woody medicinal tree species in the western coastal belt of Bangladesh
Abstract
Two trials were conducted to assess the growth performance of thirteen woody medicinal tree species planted in the year 2015 and 2018 at two different sites respectively named Baherchar and Haridrakhali of Rangabali Upazila under Patuakhali district (western coastal belt). Data on survival, height, diameter at breast height (dbh), collar diameter, stem length and number of branches was recorded from 3.5 years and 1.5 years old two trial plantations. At Baherchar site highest survival was recorded for Arjun (90%) followed by Khoier (81%), Kadam (73%), Kalojam (70%), Bohera (60%) and Shimul (60%). The highest height was recorded for Kadam (10.09m) followed by Khoier (6.72m), Gora neem (5.54m), Shimul (4.15), Arjun (3.55m) and Horitaki (3.31m). The greater dbh was also recorded for Kadam (8.57cm). The highest stem length was found in Kadam (6.89m). The greater number of branches was found in Gora neem (5). At Horidrakhali site the result revealed that the highest survival was recorded for Arjun (100%), Katbadam (100%), Pitraj (100%) and Punial (100%). The highest height was recorded in Khoier (2.97m). The highest collar diameter was observed in Satiyan (3.81cm). Considering the survival, height and diameter growth, Khoier, Arjun, Gora neem, Satiyan, Shimul, Punial, Pitraj, Horitaki, Sonalu, Katbadam, Kadam and Kalojam were found promising and suitable for planting in the raised lands of the western coastal belt of Bangladesh.

Experimental investigation of solar bubble dryer for rough rice drying in Bangladesh
Abstract
Drying is important for long term storage, maintaining quality and reducing drying loss of rough rice. Solar bubble (SB) dryer was tested at the Department of Farm Power & Machinery, Bangladesh Agricultural University, Mymensingh during Boro and Aman 2015 harvesting seasons to understand the effectiveness and potentiality of the dryer at farmers’ level as an alternative to open sun drying. SB experiment shows that the temperature was distributed uniformly throughout the dryer which was very much dependent on solar radiation. The hourly moisture removal rate was 0.6 and 0.4 % during Boro and Aman season, respectively. The drying efficiency was found 25.2 and 12.3% during Boro and Aman season, respectively. The milling recovery was found 71.5±1.0% for SB dryer and 72.3±1.3% for sundried rough rice. Head rice yield of rough rice was lower (53.6%) in SB dried product compared to sun drying method (63.9%). The germination rate was more than 80% in both seasons for SB dryer and sundried method, respectively. The operating cost of drying was observed Tk. 1.48 per kg. The SB dryer can be applicable for drying rough rice at farm level in Bangladesh.

Effects of breed and sex on serum biochemical indices of local and improved Nigerian chickens raised in the south-south region of Nigeria
Abstract
This research was done to assess the effects of breed and sex on serum biochemical indices in local and improved Nigerian chickens. Total of forty chickens (20 males and 20 females) from four breeds of (Frizzle feathered, Naked neck, Normal feathered and Noiler) chickens were selected at random from a population of two hundred and thirty birds raised under intensive management. At 11th week, blood samples were collected from the birds and used for biochemical analyses. The parameters measured include; Albumin, Total protein, Aspartate amino transferase, Alanine amino transferase, Alkaline phosphatase. Data generated were analyzed for least squares means using SAS 9s.2 (Version 2008).The result of the biochemical indices revealed no significant difference (p>0.05) for cholesterol, albumin, total protein and aspartate amino transferase among breeds but a high significant difference(p<0.001) for alanine amino transferase and significant difference (p<0.05) for alkaline phosphatase. The Normal feathered chickens had higher least squares means in cholesterol (3.10±0.10g/dl), total protein (41.17±2.50g/dl) and alkaline phosphatase (486±29.08iu/l).The least squares means also indicated that there was significant difference(p>0.05) between sex for all the biochemical parameters but the female sex had higher least squares means in cholesterol (2.98±0.13g/dl), albumin (15.52±0.85g/dl), total protein (39.09±1.19g/dl) and alanine amino transferase (26.90±1.29iu/l) while the male sex had higher least squares means in aspartate amino transferase (43.15±0.81iu/l) and alkaline phosphatase (455.00±29.47iu/l).The study revealed significant effect of breed on serum metabolites among the Nigerian chickens studied and the data generated could serve as baseline data for future improvement of the Nigerian native chicken breeds.

Association between pituitary specific transcription factor 1 gene (pit 1) and some carcass traits in sasso and shika brown chickens
Abstract
This study was conducted to check the association between PIT 1 gene and some carcass traits in 30 Sasso and 30 Shika brown chickens. Growth data were collected for 12 weeks. DNA was extracted from the blood of the chickens using the Zymo spin column text kit by Zymo Research. Polymerase Chain Reaction (PCR) was done using PIT 1 primers and PCR products were digested with MSP1 restriction enzyme to generate the genotypes. Data generated were analyzed using SPSS Version 16, MEGA 6.0 and DNASP. The results showed allele frequency of A in Sasso was 0.4375 while in Sasso, it was 0.5714. Allele frequency of B was 0.5625 in Sasso 0.4286 in Shika brown. The heterozygous frequency was 0.3750 in Sasso and 0.2857 in Shika brown. The highest expected frequency was in AB genotype both in Sasso (3.9375) and in Shika brown (3.4286). Hardy-Weinberg equilibrium was not significant (p>0.05) in Sasso chickens. In week 1, the highest body weight occurred in the genotype (BB) 83.42g. However, the highest value for body length was observed in the genotype (AA) 9.00cm in week 5, the highest body weight occurred in the genotype (AB) in Sasso 545.00±121.74g. The results exposed variation in the expression in PIT1 gene in carcass traits which could be exploited in chicken breeding programmes.

Management of ecto-parasitic mite, Tropilaelaps mercedesae Anderson and Morgan in honeybee, Apis mellifera Lin. colonies in the mid-hill areas of Nepal
Abstract
The ecto-parasitic mite, Tropilaelaps mercedesae Anderson and Morgan is one of the major limiting factors for both subsistence and commercial Apis mellifera Lin. beekeeping in Nepal. Its management by the beekeepers with chemical application regularly causes resistance in mite and contamination in bee products. So, an investigation was undertaken to explore the acaricidal properties of commonly available organic acid, plant and animal products as alternative methods for honeybee mite management. The ten-frame Langstroth colonies [7-frame honeybees with 5-frame brood] were randomly selected and divided into five groups (treatments) with four colonies in each treatment. The treatments were: formic acid (FA) (65% @ 3 ml/frame), glucose powder (GP) (@ 4 g/frame), neem seed powder (NSP) (@ 3 g/frame), 100% cow urine solution (CUS) (@ 5 ml/frame), and control from third week of May to first week of July in the mid-hill areas of Lalitpur district for two consecutive years, 2017-018. The honeybee mite infestation was determined in randomly selected fifty sealed worker brood cells on 1st, 3rd, 6th, 10th and 15th day. The parameters as percent brood infestation by honeybee mite, percentage reduction of mite infestation, efficacy of different treatments, median lethal time in days (LT50) of the treatments and survivable of honeybee mites in different treatments were recorded. The population of mites before the treatment application was found non-significant, while after treatment application mite population varied significantly among the treatments. However, the interaction between year and treatments during entire observation dates were non-significant. In case of honey yield, it was highly significant among the treatments with the highest yield in FA treated colonies. The highest honeybee mite count on brood cells was observed on control colonies (37.37) and the lowest on FA treated colonies (3.62) followed by CUS (7.87), NSP (11.0) and GP (23.38), respectively, on the 15th day after the treatment. Similarly, the percent reduction of honeybee mite was noticed the highest in FA (91.01%) followed by CUS (81.02%), NSP (71.72%) and GP (40.85%) treatments, respectively. Among the acaracidal material evaluated against honeybee mite, the efficacy of FA was found better which increased from 43.08% on the 1st day to 90.52% on the 15th day of observation. All these evidences indicate superiority of FA over other materials investigated for the management of honeybee mite. This was further strengthened with the lowest LT50 value of FA (0.72 days) as compared to other treatments, NSP (0.80 days), CUS (1.34 days) and GP (2.56 days). All these evidences elucidate the use of FA for the sustainable management of honeybee mite, T. mercedesae in A. mellifera colonies, whereas application of CUS and NSP are also advisable in the mid-hill areas. FA does not contaminate honey as it is volatile, but precaution should be taken during its application.

Abstract
The ecto-parasitic mite, Tropilaelaps mercedesae Anderson and Morgan is one of the major limiting factors for both subsistence and commercial Apis mellifera Lin. beekeeping in Nepal. Its management by the beekeepers with chemical application regularly causes resistance in mite and contamination in bee products. So, an investigation was undertaken to explore the acaricidal properties of commonly available organic acid, plant and animal products as alternative methods for honeybee mite management. The ten-frame Langstroth colonies [7-frame honeybees with 5-frame brood] were randomly selected and divided into five groups (treatments) with four colonies in each treatment. The treatments were: formic acid (FA) (65% @ 3 ml/frame), glucose powder (GP) (@ 4 g/frame), neem seed powder (NSP) (@ 3 g/frame), 100% cow urine solution (CUS) (@ 5 ml/frame), and control from third week of May to first week of July in the mid-hill areas of Lalitpur district for two consecutive years, 2017-018. The honeybee mite infestation was determined in randomly selected fifty sealed worker brood cells on 1st, 3rd, 6th, 10th and 15th day. The parameters as percent brood infestation by honeybee mite, percentage reduction of mite infestation, efficacy of different treatments, median lethal time in days (LT50) of the treatments and survivable of honeybee mites in different treatments were recorded. The population of mites before the treatment application was found non-significant, while after treatment application mite population varied significantly among the treatments. However, the interaction between year and treatments during entire observation dates were non-significant. In case of honey yield, it was highly significant among the treatments with the highest yield in FA treated colonies. The highest honeybee mite count on brood cells was observed on control colonies (37.37) and the lowest on FA treated colonies (3.62) followed by CUS (7.87), NSP (11.0) and GP (23.38), respectively, on the 15th day after the treatment. Similarly, the percent reduction of honeybee mite was noticed the highest in FA (91.01%) followed by CUS (81.02%), NSP (71.72%) and GP (40.85%) treatments, respectively. Among the acaracidal material evaluated against honeybee mite, the efficacy of FA was found better which increased from 43.08% on the 1st day to 90.52% on the 15th day of observation. All these evidences indicate superiority of FA over other materials investigated for the management of honeybee mite. This was further strengthened with the lowest LT50 value of FA (0.72 days) as compared to other treatments, NSP (0.80 days), CUS (1.34 days) and GP (2.56 days). All these evidences elucidate the use of FA for the sustainable management of honeybee mite, T. mercedesae in A. mellifera colonies, whereas application of CUS and NSP are also advisable in the mid-hill areas.

Prevalence and severity of different citrus diseases in Sylhet region
Abstract
Citrus is the World's premiere fruit crop infected by a large number of diseases and caused huge economic losses. A study was conducted from November to December 2014 at several citrus orchards of Sylhet, Bangladesh to find out the prevalence and intensity of diseases affecting different citrus species. In this study, 560 plants from seventeen citrus species were critically observed to collect data on the infection of diseases. Different citrus diseases were found among the studied population where greening, die-back, scab and canker of citrus were mostly prevailing diseases in this region. A significant variation in the disease incidence and severity was found among different species. Rough lemon demonstrated the highest susceptibility (95%) to citrus greening. But, die-back in combination with scab of citrus exhibited the maximum greening incidence in BARI satkara-1 (55%), followed by Mandarin (46.66%). The incidence of die-back was the highest in BARI kamala-1 followed by lime (93.3%). The scab of citrus showed the maximum incidence in BARI satkara-1 (50%). Alachilemon was found highly infected by canker of citrus showing 65% and 36% of incidence and severity respectively. Among all the studied citrus species, the overall disease incidence was found to be the lowest in Chinalemon. The study is a valued addition to the literature of citrus research and contributed significantly to the management of citrus disease.
