People of Bangladesh are vulnerable to disasters and have suffered repeatedly due to floods and storm surges, On 15 November 2007,a cyclone sidr struck coastal and central areas of Bangladesh and caused severe suffering to the affected people. The study was conducted with sidr affected farmers of Mollarhat Upazila of Bagerhat district to determine the extent of the problems they faced regarding lack of dwelling house, unhygienic drinking water, outbreak of diarrhoea, cholera, insufficient relief and increased salinity intension etc by the farmers to mitigate the hazardous effects of sidr on their farming systems. One hundred farmers were selected randomly for data collection through pretested interview schedule during March to April 2009. Extent of livelihood assets of the sidr affected farmers was the dependent variable of the study and their selected eight characteristics constituted the independent variables. Most of the farmers (60%) had medium livelihood assets while 20 and 14% of them had weak and strong capacity, respectively. They had the highest livelihood assets regarding natural capital and lowest capacity regarding financial capital. Effective support and long term planning from the GO and NGOs are desirable to overcome the vulnerable situation of the sidr affected farmers.

The research work was conducted from October to December 2016 on the rooftop of Agriculture Faculty Building of Sylhet Agricultural University, Sylhet to assess the effects of industrial effluents on seed germination, seedling mortality and growth of radish (Raphanus sativus L.). Effluents were collected from common dumping-off areas of Narsingdi, Tongi, Hazaribagh, Alampur, Khadimnagar, Majortilla, Bhatiary, Bayazid bostami and Sagorika under Dhaka, Sylhet and Chittagong division of Bangladesh. Maximum concentration of Pb (2.038 mgl-1), Cd (0.082 mgL-1), Ni (0.237 mgl-1) and Cr (0.172 mgl-1) were obtained in Hazaribagh industrial effluents; Fe (7.171 mgl-1) and Zn (1.938 mgl-1) were highest in Khadimnagar. Both experiments were laid out in a CRD with three replications. Radish seedlings were significantly affected by the application of different industrial effluents. Maximum seedling mortality (22.78%) at 15 DAS was observed in Khadimnagar industrial effluents, whereas zero seedling mortality was observed in control. Shoot and root length of radish also affected by effluents. Due to toxicity of heavy metals shoot length (36.97%) and root length (61.38%) were reduced compared to control along with decrease in other growth parameters of radish. Maximum number of leaf plant-1, leaf length, leaf width, fresh weight and dry weight were recorded in control whereas minimum values was recorded when Khadimnagar industrial effluents used as irrigation water followed by Hazaribagh. The overall results indicated that Khadimnagar and Hazaribagh industrial effluents were significantly contaminated with heavy metals namely Pb, Cd, Ni, Cr, Fe and Zn which have toxic effects on radish growth.

A field experiment was conducted in the Dekar haor area under Sunamganj district during the period from November 2017 to February 2018 to evaluate the influence of fertilizer doses on the growth and yield of cabbage (Brassica oleracea). Four fertilizers doses viz. Recommended dose of N-P-K-S-Zn-B @ 240-88-100-32-4.5-1.5 kg ha-1 (F1), F1 + 25% of F1 (F2), F1 – 25% of F1 (F3), and Cowdung @ 10 t ha-1 (F4) were used in the experiment following randomized complete block design (RCBD) with three replications. Data on growth, yield and yield contributing parameters were recorded. Application of fertilizer doses resulted in variations of growth characteristics of cabbage. The tallest plants were observed due to application of 25% higher fertilizer over recommended dose (F2). The longest leaves 14.33 cm and 28.54 cm were recorded in 25% higher fertilizer over recommended rate at 15 and 45 DAT. Peak spreading area 69.47 cm was in 25% less than recommended fertilizer rate (F3) at 60 DAT. The largest head diameter 69.13 cm was observed due to application of recommended fertilizer dose and the lowest 53.07 cm was in cowdung application @ 10 t ha-1. The maximum gross yield (113.13 t ha-1) and the head yield (79.43 t ha-1) were obtained with the application of recommended dose of fertilizers (F1). The highest BCR 4.5 was observed in recommended fertilizer dose. The results revealed that national recommendation and 25% more than national recommended dose both produced promising cabbage yield in haor area.

A field experiment was conducted at South Surma upazila of Sylhet district to evaluate the effect of vermicompost, cowdung and inorganic fertilizers on the growth and yield of cauliflower (Brassica oleracea var. botrytis L.) in acid soil. The experiment comprised of four treatments viz. T1 = 135-60-135-21-3-1.5 kg ha-1 of N-P-K-S-Zn-B, T2 = T1 + Cowdung (5 t ha-1), T3 = T1 + Vermicompost (5 t ha-1) and T4 = Vermicompost (10 t ha-1). The experiment was laid out in a randomized complete block design with three replications. The results on growth parameters recorded at 15, 30 and 45 DAT showed significant variation in different growth and yield contributing characters. The tallest plant (24.47 cm) was recorded at 45 DAT in T3 treatment. The same treatment at 30 DAT produced the highest number of leaves plant-1 (8.33) while T4 had the lowest number of leaves plant-1 (5.93). The longest length and breadth of the largest leaf and spreading of plants were recorded 19.60, 10.03 and 16.53 cm at 45 DAT in T3, respectively. The highest curd yield (29.72 t ha-1) was recorded in T3 treatment. Post-harvest soil analysis showed higher amount of organic matter, total N, available P, exchangeable K and available S contents than in initial soil. This might be due to residual effect of vermicompost. The results revealed that vermicompost addition with recommended dose of chemical fertilizers T3 performed better compared to only inorganic fertilizers.

Sweetpotato is a fast growing starchy root crop. It can be grown on a wide variety of soils. Soils of Sylhet region are classified into various soil series or soil groups. Several indigenous sweetpotato genotypes are distributed in Sylhet region. So far they are not being explored. From this point of view, the present study was conducted to evaluate the growth and yield performance of nine sweetpotato genotypes namely Local-1, Local-2, local-5, Local-8, Exotic-1, Exotic-2, Exotic-3, Exotic-4 and BARI SP-4. The evaluation was carried out on Ramgarh soil of North-Eastern Piedmont plains during November 2015 to March 2016 in a Randomized Complete Block Design with three replications. Morphology of leaves, vines, fibrous roots and storage roots as well as yield determinants were studied. Correlation study between morphological and yield attributes were also carried out. Correlation study revealed that primary vine number, total fresh weight, total dry matter, harvest index, storage root number plant-1, diameter of storage roots, fresh weight of storage roots were positively correlated with yield. The highest harvest index (HI) was observed in Local-1 (69.46%). The maximum number of storage roots plant-1 was in Exotic-2 (7.20). The longest storage roots were in Local-5 (14.13 cm) and thickest storage roots were in Local-8 (5.22 cm). The highest storage roots fresh weight plant-1 was obtained from Local-1 (826.10 g). The highest storage roots yield was in Local-1 (48.96 t ha-1) followed by Local-8 (42.60 t ha-1). It can be concluded that Local-1 and Local-8 would be suitable for higher yield whereas potentials of Local-2 and Exotic-3 suggested for further investigation.

Three types of tomato seedlings viz., polybag raised seedlings (polybag seedling), seedbed raised seedlings (normal seedling) and grafted seedlings (tomato grafted on wild brinjal) of BARI hybrid tomato-4 were evaluated under with and without hormone application system during the summer season of 2014 at the experimental field of Sylhet Agricultural University with view to assessing the influence of grafting and hormone application on tomato yield during summer. Seedling types had significant influence on fruit yield and plant mortality. Only 3.5% plants were infected with bacterial wilt when grown from grafted seedling while it was 18% and 20% when the plants raised from normal and polybag grown seedling, respectively. Thus the higher survivability of plants in the grafted plot ensured much higher fruit yield acre-1 (18 ton) than those of normal seedling (13.15 ton) and polybag grown seedling (12.80 ton). Application of paracholorophenoxy acetic acid had significant influence on higher tomato production. The plants applied with hormone produced 979.50 g of fruits plant-1 while it was only 724.48 g in untreated plant. However, the highest fruit yield plant-1 was recorded from the grafted tomato plants (1.06 kg) and normal seedling grown plant (1.08 kg) when treated with hormone while it was the lowest for normal types of seedling at without hormone application (0.59 kg plant-1). Results revealed that the high scope of improving tomato yield during summer using grafted seedling along with hormone application in Sylhet region.

Experiments on Aus rice were conducted at the Agronomy Research Field of Sylhet Agricultural University, Sylhet and in the farmer’s field of Jaintapur and Gowainghat Upazila, Sylhet to find out the competitiveness of Aus rice varieties against weed infestation. The experiments were carried out within the period of April to August 2014. Five commercial rice varieties viz. BR3, BRRI dhan48, hybrid variety Aloron, BRRI dhan43, Iratom-24 along with three (3) local cultivars Aina Miah, Doom and Kanihati were included in the research field trial. On the other hand, survey of thirty farmer’s field along with researcher’s managed trial were conducted to know the weed situation. In farmer’s field, 5 (five) variety namely BR3, hybrid variety Aloron, BRRI dhan55, BRRI dhan48 and cultivar Aina Miah were included. Here each variety or cultivar considered as treatment. The experiment was laid out in randomized complete block (RCBD) design with three replications. Weed Competitive Index (CI) was calculated on the basis of average yield of all varieties and weed biomass. Result indicated that eight weed species were recorded in the research field trial, whereas 28 weed species were recorded in the farmer’s field trial. The most prominent weeds in the experiment were Monochoria vaginalis, Digitaria sangunalis, Leersia hexandra, Cynodon dactylon etc. The highest weed competitive index was recorded in Aloron (2.27) and the lowest was recorded in Doom (0.42) in the research field. On the other hand, in farmer’s field trial the highest weed competitive index (2.05) was recorded in BRRI dhan48 which was followed by variety Aloron (1.71). The highest grain yield (4.04 t ha-1) was produced by the hybrid variety Aloron which was statistically identical with the variety BRRI dhan48 (3.19 t ha-1) and Iratom-24 (3.06 t ha-1). The hybrid variety Aloron produced the maximum panicle length (24.53 cm) and highest (103.53) grains panicle-1 and lowest (41.87) panicle length was in variety BRRI dhan43. The lowest yield (1.07 t ha-1) was recorded in local cultivar Doom which was at par with BRRI dhan43 (1.32 t ha-1) and local cultivar Kanihati (1.53 t ha-1).

Beef cattle fattening is a potential income generating enterprise for the small scale farmers’ in haor areas. Thus, the experiment was conducted with the aim to observe the effect of urea molasses straw for fattening bull and contribution to the income generation for small scale farmers in haor areas. The experiment was conducted at the Noagaon village under South Sunamganj Upazila of Sunamganj district from January to April 2017. Ten farmers were selected for rearing and each farmer reared one bull (2-3 years old) for fattening. Two groups of animals, treatment group treated with Urea Molasses Straw (UMS) in diet and control group without UMS supplementation, were laid out with five replications in each group. Data on body weight gain and profitability data were collected and analyzed as Completely Randomized Design (CRD). Feeding of urea molasses straw with the dietary feed had shown a positive effect on weight gain. After the end of the experimental period, mean body weight gain (g day-1animal-1) for the treatment and control group were measured as 496.41 and 236.62 g, respectively. The body weight gains of these both feeding groups were insignificant during the first fifteenth days of the experimental period, however, the difference was significant (p<0.05) for the rest of the experimental period. Moreover, higher gross margin was found in the treatment group (Tk. 14,310) than the control group (Tk. 3,810). Therefore, a significant growth performance with a profitable income for the small scale farmers’ of haor areas might be promising from beef cattle fattening by dietary urea molasses straw treatment.
