Item SIMULATION OF A MODEL FOR DIAGNOSIS AND PRESCRIPTION FOR CUCUMBER MOSAIC DISEASE(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Islam, M. S.; Islam, M. R.; Meah, M. B.The Experiments were carried out during the period of 2009 to 2013 on the epidemiological status an :--,__ -=,",./ .., prescriptions used for the management of cucumber mosaic disease with a view to simulate a diagnosis and prescription model. The survey area covered five upazillas viz. Mymensingh sadar, Kushtia sadar, Kumarkhali, Chandina and Sher-e-Bangla Nagar under four districts viz, Mymensingh, Kushtia, Comilla and Dhaka where altogether 250 farmers field were considered for observation. The highest disease incidence of mosaic of cucumber (37, I%) was recorded at Kumarkhali, while the lowest were (33.9%) in Boira Keyotkhali, Gemini virus was detected as causal pathogen for cucumber mosaic disease. The model prescriptions issued by Plant Disease Diagnostic Clinic (PDDC) found effective in the farmer's field against the Cucumber Mosaic disease in selected locations were subjected to re-evaluation under different experimentations at Plant Pathological field laboratory at BAU farm. Economically affordable management practices were re-tested in five locations of Bangladesh. Based on the re-investigation results, the model prescriptions were finally selected for the vegetable growers of the country. Model diagnosis and prescription have been proposed. These were Surni-Alpha @ I mlfl sprayed 4 times at 15 days intervals starting from first sign of the disease at 60 days after sowing for cucumber mosaic disease. The management practices were reduced of disease incidence (73.5%), disease severity (73.8%), yield increased (74.4%) over control and benefit cost ratio (BCR) was 3.40, respectively.Item BIO-EFFICACY OF CARBOFURAN 5G AGAINST BRINJAL SHOOT AND FRUIT BORER APPLIED AT DIFFERENT ROW COMBINATIONS(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Moniruzzaman, M.; Rahman, G. K. M. M.; K. H. KabirAn experiment was undertaken to determine the suitable pattern of carbofuran application for brinjal cultivation and minimize the application of carbofuran for maximum protection against brinjal shoot and fruit borer (BSFB). The experiment was conducted at the research field of Soil Science Department, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during the period from September 2008 to March 2009. The experiment was laid out in RCBD with 4 treatments and 3 replications. Considering 6m x Sm plot size for each treatment and 60 cm x 7S cm plant spacing with 40 days old brinjal seedlings. The lowest percent of shoot infestation (1.24%) was recorded where carbofuran 30 kg/ha (furataf SG used @ 90g/ 30 m'; T,) was applied in every plant of every row. It was followed by carbofuran IS kg/ha (furatafSG used @4Sg/30m'; T,) was applied in every plant of every alternate row. But there was no significant difference of percent shoot infestation between where carbofuran was applied in every plant of every row and in every plant of every alternate row. However, the highest shoot infestation (3.02%) was recorded where carbofuran 7.50 kg/ha (furataf SG used @ 22.50g1 30 nr'; T4) was applied in every plant of three alternative rows and followed by earbofuran 11.25 kg/ha (furataf SG used @ 37.7Sg/30 m'; T3) was applied in every plant of two alternative rows. Fruit infestation both in terms of number and weight followed the same trend as in shoot infestation and having no significant difference between these two treatments. The highest percent fruit infestation (36.S3%) by number was recorded in where carbofuran was applied in every plant of three alternative rows followed by carbofuran was applied in every plant of two alternative rows. The highest yield (37.67 t/ha) was obtained from where carbofuran was applied in every plant of every row and the second highest yield (37.58 t/ha) was recorded where carbofuran was applied in every plant of every alternate row, although there was no significant difference between these treatments in respect to yield. Significantly, the lowest yield (33.S6 t/ha) was recorded where carbofuran was applied in every plant of three alternative rows in which the maximum distance was maintained in carbofuran application pattern. The highest net return (4,08,SOO Tk/ha) and cost benefit ratio (1.19) was found where earbofuran was applied in every plant of every alternate row. In view of different row combinations, the higher net return and cost benefit ratio may come from where carbofuran application in ring furrow to every plant of one alternate row would be the best option to be utilized in BSFB management programs.Item THE IMPACT OF BEEF-POPULATION IMPORT-MANAGEMENT STRA TEGIES ON BEEF SELF -SUFFICIENCY IN MALAYSIA(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Yasmin, F.; Mohamed, Z, A.; Samsudin, M. N.; Jamak, M. E. A.The study has been aimed to evaluate beef self-sufficiency performance under different conditions in Malaysia. Simulation model under five scenarios of different managements was developed to analyze the impact on beef production in Peninsular Malaysia. Scenario 3 was found to be the best management to attain self-sufficiency level at reasonable time frame. Under scenario 3 (76-80% calving rate, 5-7% slaughter rate, 1-2% mortality rate of female breeding stock with 10000,5000,500 heads/year importation of female breeding stock for beef cattle, dairy cattle and buffalo respectively), 150% self-sufficiency can be achieved in 2015. The management of female breeding stock is an important component for beef production system in order to achieve the level of self-sufficiency in beef. The results indicated that lower slaughter rate of imported Female Breeding Stock (FSS) could be more suitable management strategy for higher beef self-sufficiency.Item IMPROVING LIVELIHOOD PATTERN OF HAND WEAVERS PARTICULARL Y WOMEN IN KISHOREGANJ DISTRICT OF BANGLADESH(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Sammy, H. M.; Islam, S.; Riad, M. M.; Rayhan, S. J.Bangladesh is a small South Asian country and has the highest population density in the world. It has an agro-based economy, where about half of the total population is female and a majority of them, about 80%, live in rural areas. Most of the rural women have little opportunity to participate in intra-household, socio-economic and political decision-making processes as well as very limited interaction with people outside of the home. The works of women in Bangladesh are mostly confined to the homestead due to cultural, religious and social restrictions. Most of the rural people are poor and family depends on income of male person; but ensuring the income of women is an essential precondition for the elimination of poverty. At present women are involved in some income generating activities, Hand Weaving is one of them, not only women are taking benefit from this new sector but also men are getting more advantages from this. Socio-economic analysis, cost & return was estimated to show their income level as well as livelihood. The main objectives of the study are to improve livelihood of rural people, to analyze the proportion of income from various sources, to compare the income of weaver between present and past and to identify the determinants of income of weaver at household level through Multiple Classification Analysis (MCA).Item INCOME INEQUALITIES AMONG THE FARMERS IN SOME SELECTED AREAS OF BANGLADESH(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Rahman, M. S.; Mila, F. A.; Hasan, M. R.; Rayhan, S. J.The study was conducted in Jessore and Rangpur district of Bangladesh to determine the income inequality among the farmers. Gini-coefficient and multiple regression analysis were used 10 achieve the objectives of the study. The findings of the study indicated more than 50% of the total income was come from non agriculture sources. More income inequality was found among the farmers of Jessore district than that of Rangpur district. Overall Gini-coefficient was found to be 0.25 in the study areas. Income from non agriculture sources contributes 52% of the overall income inequality. Income, education, family size, access to credit etc. had positive and significant effect on the welfare of the farmers. Credit with low interest rate, low cost production technologies played a vital role to increase the income as well as the welfare of the farmers in the study areas.Item FEMALE LABOUR WAGE AND THEIR WAGE GAP WITH MALE COUNTERPART IN SOME SELECTED AREAS OF BANGLADESH(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Sannyashi, P. R.; Haque, S.; Yasmin, F.; Alam, M. S.This study addressed the nature and extent of female wage labour and the wage gap with their male counterpart in the selected areas of Sirajgonj and Dhaka Districts of Bangladesh. There were four categories of labour. Farm survey method was used to collect primary data from the field labour and the rice mill worker and labour of construction work at few villages under Royganj, Tarash, and Salanga Upazilas of Sirajgonj and Dhaka district for the study. ANOYA and ANCOYA Models were used for analyzing the data set. It is noted that, the female labour's working hours/day, working days/week are much less than male labour that is why wage of female labours is much lower than the male labours in selected areas of Bangladesh. It is also noted that the wage rate is much lower in the case of female workers. The major findings of the study indicated the way of increasing income of female labour depends on the reduction of the wage gap (I 239Tklmonth).Therefore, the study firmly concluded with the recommendation that the wage (tklhr) of female worker should increase rationally for ensuring the equal treatment of both male and female.Item EVALUATION OF SOME WHEAT VARIETIES AGAINST LEAF BLIGHT (Bipolaris sorokinianai(Sher-e-Bangla Agricultural University Research System (SAURES), Dhaka, Bangladesh, 2013-07) Laila, L.; Aminuzzaman, F. M.; Islam, M. R.; Rayhan, S. J.; Tania, S. N.A net house experiment was carried out in the field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh to evaluate ten wheat varieties against leaf blight (Bipolaris sorokiniana). The wheat seeds of varieties Sonalika, Kanchan, Barkat, Shatabdi, Aghrani, Pavon-76, Akbar, Gourab, Sourav and Protiva were collected from Banngladesh Agricultural Research Institute (BARl), Gazipur. At ear initiation stage, flowering stage, milking stage and hard dough stage minimum disease severity was recorded in the variety Shatabdi and maximum in the variety Sonalika. The highest number of grains/ear (36.95) and number of healthy grains/ear (36.43) were recorded in the variety Shatabdi The highest 1000-seed weight (43.1Og) were recorded in the variety Gourab and lowest in the variety Protiva. The highest grain yield/pot (5.97g) was recorded in the variety Gourab and lowest yield/pot (4.40g) in the variety Pavon-76. The highest straw yield /pot (14.13g) was recorded in the variety Barkat and lowest (9.IOg) in the variety Shatabdi.
