COMPARATIVE ECONOMIC STUDY ON DAIRY FARMING IN SOME SELECTED AREAS OF BANGLADESH Alam, S. B.; Nasrin, M. A.; Alam, M. J. Dairy development through Field Fertility Clinic (FFC) is relatively a recent effort in Bangladesh. Farmers in the FFC areas are increasingly becoming interested in raising dairy cows. This paper is an attempt to examine the relative profitability of raising dairy cows by FFC members and non-members control farmers. The study revealed that annual average milk production per farm was 10075.32 litres and 8662.56 litres for FFC member and non-member control fanner respectively. In the case of FFC member farmer net return per farm was US S 852.44 while in the case of non-member control farmer. The member was US S 747.13. Return from per FFC member farm was higher by US $ 105.31 than the non-member control farm. The net change of dairy income from a farm was observed to be US S 407.22 and US $ 205.90 due to introduction of FFC veterinary services and recommended feeding practice respectively. It has been found that using the FFC veterinary services the net change of farm income was higher (US $ 407.22) than the FFC recommended feeding practice. CobbDouglas production function analysis was done to determine the effects of variables mainly for concentrate cost (X ,), rice straw cost (X,), green grass cost (X,), labour cost (X.), veterinary services cost (X,) and FFC intervention (D) on milk return. The finding suggested all of the selected variables had significant impact on milk return. It was further observed that all the resources except rice straw were used efficiently.

STUDY ON THE RELATIVE ABUNDANCE OF INSECT PESTS AND THEIR NATURAL ENEMIES ASSOCIATED IN RICE Rahman, M. M. The field experiment was conducted at Bangladesh Agricultural University (BAU) farm in Mynmensingh during Boro season. Thirteen different rice pests viz. Short-homed grasshopper, yellow stem borer, dark- headed striped borer, pink borer, white-backed plant hopper, green leafhopper, brown Plant hopper, zigzag leafhopper, whorl maggot, long homed grasshopper, rice leaf roller, green semi looper and rice bug were recorded during the present study. Among the stem borers, yellow stem borer (Scripophaga incertulasy was most dominant throughout the crop season followed by the dark-headed striped.borer (Chilo polychrysa and pink borer (Sesamia inferens). Green leafhopper lNephotettix virescens) was the dominant species among the plant-sucking insects. The population of leaf feeding insects was quite high and their densities varied in relation to plant age and season. Local improved Pajam had lower infestation than high yielding variety BR2. Twelve natural enemies (predator/parasitiod) were recorded from the crop field. They were carabid beetle (Ophionea nigrofaciatai, damselfly (Agriocnemis famina famina), ladybird beetle (Micraspis discolor, M. crucea, Menochilous sexmaculatus), spider (Tetragnathus sp. Oxyopes sp. and Lycosa pseudoanmulata), mirid bug (Cyrtorhinus lividipennisi, Tetrastichus schoenobii and Telenomus rowani. The ladybird beetle Micraspis discolor was abundant from early to late stage of rice crops.

STUDY ON THE EFFECT OF FEEDS AT DIFFERENT LEVELS OF PROBIOTIC (PROTXIN) SUPPLEMENTATION ON PRODUCTION PERFORMANCE OF LAYING HEN Wadud, M. A.; Alam, M. J.; Beg, M. A. H.; Hossain, M. M. The study was conducted to determine the effects of dietary supplementation of a commercial probiotic (Protexin) on daily feed consumption, egg yield, egg weight, feed conversion, external and internal qualities of egg and livability in layer hens. To achieve the objectives a total of96, 42 weekold layers arranged in four dietary treatment groups including control, containing 8 birds! replication supplemented with 0, 0.5, 1.0 and 1.5% probiotic for a period of 16 weeks. The study reveals that the hen day egg production, feed conversion, egg weight and mass, egg shell weight, egg thickness and egg breaking strength increased linearly with the use of dietary protexin. However, livability and internal egg quality were not altered with the use of dietary protexin. Present study concluded that dietary supplementation of probiotic promote the laying performance and most of the external quality characteristics of eggs. In conclusion, it is recommended that dietary supplementation of probiotic at the rate of 1.5 gm per kg feed in the layer ration may be economically potential.

PRACTICES OF INTEGRATED PEST MANAGEMENT USE BY THE FARMERS Islam, M. A,; Hossain, M. A.; Amin, M. R.; Bashar, M. A. The purpose of the study was to determine practices of !PM use by the farmers and to explore the relationship between the 'selected characteristics of the farmers and their use of rPM practices. The selected characteristics were: Age, Education, Family size, farm size, training received, annual family income, extension media contact and agricultural knowledge. The study was conducted in Birampur Upazila under Dinajpur district. Data were collected from randomly selected 108 farmers using an interview schedule. Pearson's product Moment Correlation was used for the statistical analysis. The findings revealed that majority (97.3 %) of the respondents had medium to high use of !PM practices. Only 2.7 percent of the respondents had low use oflPM practices. However, use of practice ofIPM in crop production by the farmers had positive significant relationship with their education and contact with extension media exposure, while age of the respondents had significant negative relationships with their practices. Among the five selected iPM practices, the farmers were found having good extent of use of IPM practices. Among the 5 identified IPM practices "chemical control" ranked first and 2nd, 3'", 4th and 5th position in the rank order were "control by cultivation", "cultivation of pest resistant variety", "mechanical control" and "biological control" respectively.
