(DEPARTMENT OF AGROFORESTRY AND ENVIRONMENTAL SCIENCE, SHER-E-BANGLA AGRICULTURAL UNIVERSITY, DHAKA-1207, 2021-12) ISLAM, MD. SHARIFUL
The experiment was carried out at Agroforestry Field Laboratory, Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from January 2021 to April 2021 to find out “Effect of Moringa leaf extract on growth and yield of Tomato (Solanum lycopersicum L.)”. The pot experiment consisted of six treatments viz., T0, T1, T2, T3, T4, and T5 (control, 10 ml, 20ml, 30 ml, 40 ml, and 50 ml concentrations of Moringa leaf extract respectively). This experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. In the case of growth parameters, the highest plant height (62.00 cm) and the number of leaf plant-1 (52) were observed in T5 whereas the lowest result was observed from T0 treatment with plant height (38.50 cm) and the number of leaf plant-1 (27). In terms of yield contributing parameters with Moringa leaf extract, T5 showed the lowest days (39 days) to 1st flowering whereas the highest days to 1st flowering were achieved from T0 treatment at 50 days. The highest fruit number plant-1 (24), individual fruit weight (65 g), and fruit yield ha-1 (70.2 t) was found in the treatment T5 while the lowest number of fruits per plant (8), individual fruit weight (44.78 g), fruit yield ha-1 (31.5 t) was obtained from T0 treatment. Different concentrations of Moringa leaf extract with Tomato plant had a strong positive relation with around all parameters. To base on observed data points, predicted that 50 ml concentrations of Moringa leaf extract will supply the optimum Tomato yield ha-1(70.2 t). This study indicates that the Moringa leaf extract used significantly increased the growth and yield of tomato plants in all the trials with fresh leaves, regular branching, healthy fruits, and regular flowering.

An experiment was conducted at the Central Laboratory in Sher-e-Bangla Agricultural University, Dhaka; during September 2014 to March 2015 to identify the effect of salt industries byproduct on growth and yield of lettuce in soilless culture. Three nutrient solutions were considered as treatments, viz. T – ½ Rahman and Inden (2012) + 0 ml of salt industries byproduct (SIB), T 2 1 – ½ Rahman and Inden (2012) + 0.5 ml of SIB, T – ½ Rahman and Inden (2012) + 0.75 ml of SIB. The experiment was conducted in a completely randomized design (CRD). Salt industries byproduct showed significant variation in most of the parameters. The highest plant height (19.53 cm) was recorded from T 1 3 while the lowest plant height (15.61 cm) was found in T 3 . Number of leaves per plant was maximum (10.61) from T whereas minimum (8.80) was recorded T 3 . Higher leaf breadth (11.36 cm) was recorded from T 1 which was statistically similar to T 2 and lower (9.56 cm) was from T , higher leaf length (17.61 cm) was found in T 1 and lower (13.90 cm) was in T 3. 3 Maximum fresh weight of lettuce (48.81g/plant) was recorded from T 1 which was statistically similar to T and minimum (27.94 g/plant) was in T 1 2 . In case of ascorbic acid content, the maximum amount of ascorbic acid content (157.61 mg/100g fresh weight) was recorded from T and the minimum (127.41 mg/100g fresh weight of lettuce) was in T 1 3 . In case of β-carotene content, the maximum amount of β-carotene content (3207 µg/100g fresh weight of lettuce) was recorded from T and the minimum (3100 µg/100g fresh weight) was in T 1. 3 Similar trend was also found in other growth analytical parameters (viz. leaf area, leaf area ratio, leaf mass ratio, root weight ratio, net assimilation ratio and relative growth rate), which was the best from T but LA, RGR and NAR were statistically similar to that of T 2 1 . Meanwhile all the physiological parameters were lowest in T (½ Rahman and Inden (2012) + 0.5 ml of SIB) can be used to get higher amount of ascorbic acid and β-carotene content with moderate yield

(HAJEE MOHAMMOD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR, 2017-06) ISLAM, MD. SHARIFUL; Dr. Md. Shajedur Rahman
The present study was carried out to detect the prevalence of anaplasmosis in cattle at Rayganj and Ullahpara upazila in Sirajganj district of Bangladesh and to evaluate the therapeutic efficacy of traditional drugs like Oxetetracycline (Renamycine® ), Imidocarb diproprionate (Babenil® ) and Diminazine aceturate (Berenil® ) against anaplasmosis in cattle. The study was conducted from July 2016 to December 2016. During six months of study period a total of 150 blood samples were collected from clinically ill and suspected cattle, among which 28 samples were positive for anaplasmosis by Geimsa stained blood smear method. It was observed that the overall prevalence of anaplasmosis in cattle was 18.67%, where 16.25% was Geimsa stained blood smear at Rayganj and 21.43% at Ullapara upazila respectively and the variation was not statistically significant (p>0.05). In respect of age the prevalence of anaplasmosis was significantly (p< 0.05) higher (31.7%) in 2-3 years of age group cattle than above 3 years (16.67%) and 6 months to 2 years age (10.20%) group. On the basis of sex, it was observed that the variation in prevalence in male (15.94%) and female (20.99%) was not statistically significant (p>0.05). Breed-wise prevalence was higher in crossbred cattle (19.5%) than local cattle (17.8%), was not statistically significant (p>0.05). It was observed that among three drugs used in this study, the best effectiveness of drugs was seen by Oxytetracycline (Renamycine LA® ) @ 10 mg/kg body weight followed by Imidocarb dipropionate (Babenil® ) @ 3.5 mg/kg body weight moderately and less by Diminazine aceturate (Berenil® ) @ 3.5 mg/kg body weight. From the study it was evident that cattle were infected with the organisms and caused a heavy economic loss which recommended to take necessary preventive measurements.

A field experiment was conducted at Sher-e-Bangla Agricultural University. Dhaka during April to August, 2009 with a view to find out the influence of plant spacing and weed management methods on the yield of white jute (var.CVL- 1). The experiment consisted of four weed control methods viz, two times hand weeding with one raking, herbicide Whip Super 9 EC (FenoxapropP-ethyl: C 13H16C1N05 ) application at 15 DAS, two times hand weeding at 20+40 DAS and three times hand weeding at 15+30+45 DAS and Ibur plant spacing viz., 20 cm x 10 cm, 25 cm x 10 cm. 30 cm x 10 cm (20, 25 and 30 cm row to row with plants spaced at 10 cm intervals in the row) and broadcasting. The dominant grass weeds were Cynodon dactylon (43%), Echinochloa colonam (29%) and Eleusine india (22%). Results showed that plant spacing differed significantly and 25 cm x 10 cm spacing gave the highest (3.12 t ha") fibre yield which was statistically similar with 20 cm x 10 cm. Two times weeding and one raking gave the highest (3.12 t hi') fibre yield which was statistically similar with herbicide application (2.97 t ha"). Interaction effect showed highest fiber yield (4.02 t ha") was obtained from 20 cm x 10 cm spacing with herbicide application. Whip Super 9 EC @ 615 ml ha" effectively controlled the grass weeds providing higher fibre yield and net 7.13 taka return per taka invested whereas 6.51, 5.18 and 5.34 taka from two times hand weeding with one raking, two times hand weeding and three times hand weeding, respectively.

(DEPARTMENT OF PLANT PATHOLOGY, 2018) ISLAM, MD. SHARIFUL
A field experiment was conducted at the central farm of Sher-e- Bangla Agricultural University, Dhaka-1207, during March to July, 2017. The aim of the study was to investigate the varietal performance of two popular okra varieties namely BARI Dherosh-1 and Green finger against Okra yellow mosaic virus (OYMV) by controlling the insect vectors with Imidacloprid and light reflecting silver color mulch. Two experiments were carried out in two blocks layouted with RCBD and four treatments viz. T 0 (control/no spray), T 1 (only mulching), T 2 (1 spray+ mulching) and T (3 times spray) with three replications. The mulch was used at 15 DAS and insecticide was sprayed at 30 DAS and continued with 15 days interval. At 95 DAS, the lowest disease incidence (%) was estimated in T (one spray+ mulching) that were 34.72 % and 19.65 % in BARI Dherosh-1 and Green finger respectively. The highest disease incidence (%) was estimated in T 0 2 (untreated/control) that was 73.71 % in BARI Dherosh-1 and 51.11 % in Green finger. In case of morphological parameters; the highest number of leaves, flowers and fruits per plant was recorded in T (one spray+ mulching) and that was 46.33, 9.33, 7.00 in BARI Dherosh-1 and 48.00, 12.33, 10.67 in Green finger respectively up to last harvesting. Yield and yield contributing characters were significantly varied among the treatments. The highest yield per plant and plot was obtained in T (one spray+ mulching) treatment in case of both varieties (0.15 kg/plant, 2.86 kg/plot in BARI Dherosh-1 and 0.24 kg/plant, 4.37 kg/plot in Green finger). The highest plant height was also found in T 2 (one spray+ mulching) in both varieties (128.62 cm and 130.33 cm respectively). It was also observed that when percent disease incidence increased, the yield of okra was also decreased. However, considering the economic conditions/cost-benefit ratio T 2 2 (one spray+ mulching) gave the best results in terms of controlling the insect vector whitefly.

The purpose of the study was to ascertain the problems faced by the farmers in bean production and to explore the relationships between the problems faced by the bean farmers and their selected characteristics. The study was conducted in four villages of two unions under Atghoria upazilla of Pabna district. Data for this study were collected from 106 bean farmers by using an interview schedule during 15 dec, 2017 to 15 jan, 2018. The interview survey revealed that highest proportion (71.70 percent) of the farmers had medium problem faced in bean production, while 16.04 percent had high and 12.26 percent had low problem faced. Among various problems faced by the farmers non-availability of quality pesticides was the highest followed by nonavailability of quality fertilizers. Lack of irrigation was the least important problem. Correlation analysis indicated that education, training exposure, organizational participation, extension media contact and farmers’ knowledge had significant negative relationship with their problem faced. Age had significant positive relationship with their problem faced. The characteristics, namely family members, farm size, annual family income, bean cultivation area, and credit received by the farmers had no significant relationship with their problem faced.
