Abstract: Jessore district is rapidly growing and a densely populated town of south western zone of Bangladesh. Due to rapid urbanization and population growth, supply water demand is increasing day by day in Jessore pourashava areas. Thus, this study was carried out to understand the existing water supply and its demand. The study was conducted among 80 families, where total family members were 770. Reconnaissance survey and sampling unit methedology was used based on questionnaire for data collection followed by data interpretation and data analysis. Primary information was collected through questionnaire survey conducted with person to person from September to November, 2012. From each 20 identical sampling points, 4 samples were collected randomly. This study revealed that Jessore pourashava has per capita water demand is nearly 250 L/day, but pourashava supply about 72 L/capita/day, which is not enough for them. Thus, they meet their demand from their own sources. There are some other associated problems with water supply such as time of water supply, impurities in supplied water, low water pressure etc. About only 50 percent consumers are satisfied to pourashava water supply. Pourashava may be able to minimize this supply and demand gaps; and increase consumer satisfaction by installing more pumps which will withdraw more water for supply in pourashava areas. Monitoring and reduction of wastage of supply need to be addressed by increasing manpowerof pourashava. Key words: Water supply, Jessore pourashava, consumer satisfaction, demand gap

Abstract: Mrigal (Cirrhinus cirrhosus) is a first growing commercial cultured species in Bangladesh. The initial energy gain of this fast growing specis depends on the protein and energy ratio in the diet. Insufficient amount of essential protein in feed hampers growth and new body tissue building. Therefore, an aquarium trial of 60 days was undertaken to evaluate the growth performance of Mrigal, with considering energy ratio in laboratory condition. The experiment was conducted with Cirrhinus cirrhosus fingerlings to measure protein energy ratio of five formulated feed with locally available ingredient which containing 33% dietary protein level. The experiment was comprised of five treatments having with two replicates containing 15 fingerlings of mean total initial weight of 13 0.02g. Five diets were formulated with five group energy levels (4.22, 4.06, 4.07, 4.35, 4.25 Kcal/g). From this study it has been found that F5 (mixed plant based protein) and F1 (fishmeal) showed highest and lowest food conversion ratio (FCR), respectively. While the lowest and the highest value of specific growth rate (SGR) and FCR was determine the vice versa between F1 and F5 treatments. The result showed that diet containing with 4.35 Kcal/g gross energy level and 75.86 mg protein energy ratio produced significantly (P<0.01) best growth. Key words: Cirrhinus cirrhosus, feed, aquarium and protein quality

Abstract: A study was conducted to identify the cause of virus disease-like symptoms developed naturally in marigold (Tagetes erecta L.) plants in Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur.The natural symptoms in marigold consisted of yellowing, mosaic, shoestring, mottling and curling of leaves resulting sever stunting of the infected plants. The ailments were found to be sap transmissible to marigold inducing identical symptoms as observed in naturally infected plants. Double Antibody Sandwich Enzyme-Linked Immuno-Sorbent Assay (DAS-ELISA) and Indirect Enzyme-Linked Immuno-Sorbent Assay (I-ELISA) detected the mixed infections of Cucumber mosaic virus (CMV) and Papaya ringspot virus (PRSV) from the naturally infected marigold plants. Chenopodium amaranticolor and Gomphrena globosa were found to be good local lesion host producing chlorotic and necrotic local lesions in the inoculated leaves respectively. The pure isolates obtained from the local lesion by using Chenopodium amaranticolor when used for host range test. It was observed that the virus had wide host range which included the plants of Amaranthaceae, Chenopodiaceae, Compositae, Cucurbitaceae, Leguminosae, Malvaceae and Solanaceae. The dilution end point, thermal inactivation point and longevity in vitro were determined as 10-6, 65C and 9 days, respectively. Moreover, the pure isolate obtained from the local lesion did not produce some symptoms like shoestring in marigold which observed in naturally infected marigold plants. The host range test, dilution end point, thermal inactivation point and longevity in vitro revealed that the purified isolate was the CMV. The results suggested that the virus was CMV, but not PRSV from the naturally infected marigold samples. The results of the study revealed that the virus disease-like symptoms manifested in marigold plants had mixed infection of CMV and PRSV. Key words: Investigation, Virus, Disease, Marigold, Tagetes erecta L.

Abstract: A total of 21 farms and 10542 broiler birds from 12 villages of 3 upazila under Barguna district in Bangladesh during June 2014 to July 2014 were studied. Among selected farms, 47.62% were small (200-450 birds) and 52.38% were medium (500-1000 birds) and most of the farmers (71.40%) were with secondary level education while majority (61.90%) had no training in broiler farming. However, 42.86% farmers reared Hubbard Classic and 38.09% reared Cobb-500 while the rest farmers reared Arber Aceres, Ross and Lohmanh commercial hybrid broiler. Several poultry hatcheries and feed companies were involved to supply day old chicks and feeds through their respective dealers to the broiler farmers in the study area. All broiler houses were open sided and most of them (85.71%) were with gable type roof of corrugated iron sheet. Most of the farmers (95.20%) were using sawdust as litter materials and all farmers were using the disposed litter as fertilizer. All farmers were using electric brooder and brooding their birds for 7 days while 85.70% farmers were using hurricane lantern for standby power supply for brooding period. All farmers were using Newcastle and Infectious Bursal Disease vaccine and 81% farmers were de-worming their birds. About 85.7% farmers reported that Marek’s disease vaccine were administered in day old chicks at hatchery level while 81% farmers sale their live broiler at local market and about 52.40% farmers use their disposed feed bags of their own farm and household purpose. Mean live broiler weight at marketing age, feed conversion ratio and bird mortality rate were 1502.38±35.27gm, 1.93±0.04 and 3.51±0.65 %, respectively. Maximum broiler farmers had secondary level education and had no training. Broiler farming in Barguna district has generated employment opportunity in this sector. Bank loan with easy access and lower rate of interest might be helpful for the broiler farmers to run their enterprise without dependency on dealers. Field survey primary data and farmers opinion regarding day old chicks price and live broiler marketing suggested that selling live broiler at high price and buying day old chick at low price make the farm operation profitable and vice versa. Again farmer’s opinion suggested that higher feed price is reducing the profitability of broiler farms. Hence, it might be concluded that higher feed price and day old chicks and live broiler market instability are the major challenges in broiler farming in Barguna district of Bangladesh. Key words: Prospect, challenges, broiler farming, feed, chicks and market instability

Abstract: The study was undertaken to find out the interaction among Moringa oleifera, a perennial medicinal tree and Wheat (Triticum aestivum). Five different concentrations (0% i.e. fresh water, 25%, 50%, 75% and 100%) for each of Moringa leaf, bark and root extracts were used to examine the effects on germination and growth of Triticum. Germination percent and plumule length was reduced compared to control. Bark extract concentration of 25% produced longest hypocotyls (58mm) and flag leaf (17.28cm); and 50% produced longest (60.75cm) plant. Highest SPAD value (60) was recorded in 50% concentration of leaf extract applied plant. Triticum tiller number was positively affected by 50%, 100% leaf and 50% bark extracts. Soil moisture percent was increased with extract application. Longest (11.08cm) and shortest (9.5 cm) spike was recorded on 75% bark and 25% root extract application. All concentrations of leaf and root extract shown negative result for root and shoot weight. Maximum and minimum Triticum grain weight was recorded at 50% Moringa bark and 50% Moringa leaf extract, respectively.
