  Twenty four indigenous autosomal dwarf hens were selected and divided equally into 3 groups. Rhode Island Red, White Leghorn and Fayoumi Cocks, 2 for each were placed to each group respectively for breeding. Sixty eggs were selected from each group and hatched in a forced draft incubator. Among those, 36 healthy day-old chicks from each group were selected and reared up to 20 weeks of age. The chicks were identified as normal and dwarf genetic groups at 8 weeks of age. The aim of this study was to observe the reproductive parameters of crosses and parameters related to the meat yield of normal and dwarf genetic group of crossbred chicken under farm condition. Fertility, hatchability on total eggs and hatchability on fertile eggs of cross B (95.57; 68.71; 72.41) were higher (p<0.01) than cross A (93.44;63.44;67.62) and cross C (90.92;60.89;67.19). Dead-in-germ and dead-in-shell were statistically higher (p<0.01) in cross C than cross A&B. Reduced adult body size, improved feed conversion and higher livability were found in all genetic groups of dwarf crossbred. Among those, White Leghorn was found as the best one also considering its different dressing yields. Advantages of adw gene in terms of a good scavenger could better be exploited by introgressing in exotic smaller breeds like White Leghorn from indigenous dwarf chicken.

  A total of 63 day-old straight run Layer chicks up to 45 weeks of age on 3 isonitrogenous and isoenergetic diets D1 (6% PC+ 0% SWP), D2 (0% PC+ 6% SWP), and D3 (0% PC+ 8% SWP) were fed to observe the effect of dietary SWP on growth and egg production performance. This study revealed that profitability, growth and egg production performance of RIR pure line were significantly (P< 0.01) higher in D2 dietary treatment groups as compared to D1 and D3 treatment. No significant difference (P< 0.05) in livability was found which could be attributed to the dietary SWP levels. Feed cost/kg was gradually declined on increasing dietary levels of SWP. The efficiency by the birds receiving SWP were better as compared to the control. The result of this study demonstrated that cheaper SWP could be an excellent substitute of costly protein concentrate in formulating diets for layers leading to increase profitability.

  Ten rice cultivars (Oryza sativa L.) were tested for their salt tolerance at three levels of salinity, 4.5, 8.5 and 12.5 dS m-1 electrical conductivity (EC) and tap water as control. A 4x10 factorial experiment in split-plot design was used with three replications. Data taken 6 weeks after salt application were reported. Severe effects of salt on rice plant growth were seen even at 4.5 dSm-1. Growth was arrested immediately after application of 12.5 dS m-1 salt but not in other lower salt treatments (8.5 and 4.5 dS m-1). However, with time, salt injury symptoms were clearly visible in all plants growing in all levels of salt and showing different symptoms. The degree of injury was greater in the highest salt concentration (12.5 dS m-1). The symptoms appeared mostly in older leaves and the upper portion of the leaves rolled in and withered away. The emerging leaf blades were tightly rolled; the tips were severely withered and necrotic. However, the younger leaves of the affected plant remained succulent and looked darker green. The affected plants looked stunted and most of the young tillers gradually died. Salt injury symptoms varied with concentration of salt and between cultivars. The relative salt sensitivity of cultivars was not consistent across salt levels indicating cultivar differences in threshold levels of salt tolerance. All plant parameters decreased significantly in all cultivars with increasing salinity. However, leaf area, shoot and root fresh weight were relatively more affected and the magnitude of reduction varied between cultivars. Limited differences between cultivars for salt tolerance were seen during vegetative growth. An index combining all plant parameters measured, suggested that V2, V3, V5 and BR23 were relatively tolerant of salinity than others. Neither reduced photosynthetic capacity nor reduced turgor appeared to be the major reason for the reduced growth. Rather, reduced growth may be the result of disturbed mineral nutrition. There was no correlation between sensitivity at germination and later growth stages. The results suggested that screening of rice cultivars for salt tolerance should be at salt sensitive stages.

  The study was carried out to identify resistant rootstocks of Solanum species for grafting of cultivated eggplant varieties against root-knot nematode and to evaluate the grafting compatibility of eggplant varieties with wild Solanum root-stocks. Three experiments were conducted in this respect. Six wild Solanum root-stocks were screened against root-knot nematode (Meloidogyne incognita). The root-stocks Solanum torvum and Solanum sisymbriifolium showed resistant reaction against root knot nematode. Fourteen varieties/genotypes were screened against root-knot nematode among which six varieties/genotypes showed resistant reaction. Three cultivated eggplant varieties viz., Sufala, Singnath and Kazla were grafted on Solanum torvum and Solanum sisymbriifolium. The highest grafting success was 95% in case of Solanum torvum with Sufala and the lowest (85%) in Solanum sisymbriifolium with Singnath. The success of grafting was not affected significantly due to the effect of scion and or of root stocks. The grafted plants showed resistant reaction against the disease while the scion plants showed susceptibility in the sick beds. The grafted plants also showed resistant reaction against the disease in the field conditions. The grafted plants also outyielded compared to the scion plants. The grafting combination Solanum torvum with Sufala gave the highest yield compared to other grafting combinations and non-grafted plants.

  A socio-agronomical survey and a laboratory experiment on weed seed mixture with rice seed were carried out at the three different villages of Mymensingh district and in the laboratory of Bangladesh Agricultural University, Mymensingh respectively during the period from January to June 2002 to know the farmer’s knowledge and idea about the impact of weed seed mixture on the quality of rice seeds, and to know the status of seed purity in rice collected from different locations of Bangladesh. In the socio-agronomical survey, 100 farmers from six villages e.g. Kazirshimla, Dewanibari, Seedstore, Bharadoba, Churkhai and Rampur under three Upazilas namely Trishal, Bhaluka and Sadar were randomly selected for interview. Pre-prepared questionnaire were used to ask questions on different aspects of weed contamination with rice seeds. Results revealed that 90% farmers of the area cultivated IR50 and only 3% farmers grew BR2 rice variety. They got higher average yields from IR50 (1.96 t ha-1) than other varieties e.g. BR2 (1.65 t ha-1) and BR3 (1.75 t ha-1). Farmers found five noxious weed seeds e.g. Echinochloa crusglli, E. colonum, Cyperus iria, Scirpus spp. and C. difformis in the rice seeds. E. crusgalli was appeared as the notorious weed to rice farmers. Forty percent of the interviewed farmers were educated up to class five and literate farmers used higher seed rate, which led to less weed infestation in the field. Eighty nine percent farmers used their own seed, which were produced and processed with care, and there was less possibility of weed seed contamination. Eight percent farmers used seeds from market, which contained more weed seeds in rice seeds. Laboratory analysis of seed samples collected from different locations of the country revealed that location has an impact on the weed seed mixture in rice seeds. Samples collected from the village more away from Bangladesh Agricultural University, Mymensingh contained more weed seeds. The purity percentage of farmers saved seed was about 95% and it contained 0.08% weed seed. The weed seeds found in the farmers saved seed samples were E. crusgalli, E.colonum, Scirpus spp. and Cyperus difformis.
