  The experiment was carried out with an aim to assess the quality of Dahi prepared from cow, goat and buffalo milk. With that understanding, milk samples were collected from Bangladesh Agricultural University Dairy farm; Senbari, Mymensingh; Gobiddocher, Mymensingh and Dahi samples were analyzed in the Dairy Technology and Animal Nutrition Laboratory of the Bangladesh Agricultural University, Mymensingh. The parameters used to monitor the quality of Dahi samples were physical (smell and taste, body and consistency, color and texture), chemical (protein, fat, total solids, ash, acidity and pH) and microbiological (gram positive rods and cocci, total viable count, coliform and mould count). From the result of all parameters it can be concluded that Dahi prepared from cows milk in the Dairy Technology Laboratory, Department of Dairy Science was superior to Dahi samples in same place from buffalo and goat milk. Most of the nutritional parameters it can be found that Dahi sample prepared from buffalo milk scored the highest. From the nutritional point of view it can be showed that Dahi prepared from buffalo and goat milk was not so bad. So, the people of our country are suggested to prepare Dahi from cow, buffalo and goat milk and also follow to strict hygienic conditions in order to get good quality Dahi.

  A field experiment was carried out to study the effect of different tillage practices on some soil physical and chemical properties. The soil was calcareous grey belonging to Sonatala series of Old Brahmaputra flood plain soil. The treatments comprised of To, T1(CP2), T2(CP3), T3(CP4), T4(PT2), T5(PT3) and T6(PT4). The bulk density (1.20 g cm -3) was h igher in To(no tillage) treatment than that of any other treatment. The lowest bulk density (0.86 g cm -3) was found at T6 (PT4) treatment. Bulk density significantly varied within the depths. The highest bulk density was recorded in 20-30 cm soil depths and the lowest was 0-10 cm soil depth. Air filled porosity and soil moisture content increased remarkably by T6(PT4) treatment compared to control. The highest organic matter was 1.60% and the lowest was 0.78% under To(control) and T6(PT4) treatment respectively. The NH4-N, available S, exchangeable K significantly influenced due to tillage operation whereas NO3-N, available P and exchangeable Ca did not respond significantly. Available N, P, S, exchangeable K and Ca decreased with the increasing of depth.

  A field experiment was carried out to study the effect of different tillage practices on root growth and yield of rice in silt loam soil. The soil was calcareous gray belonging to Sonatala series of Old Brahmaputra flood plain soil. The treatments comprised of no tillage-(To), T1 (CP2), T2 (CP3), T3 (CP4), T4 (PT2), T5 (PT3) and T6 (PT4). The highest root mass density of 2.66 mg cm -3 and the lowest root mass density 0.90 mg cm -3 were found under T6 (PT4) and To (control) respectively. The maximum root mass density (4.22 mg cm -3) was recorded at 0-10 cm depth of soil. The root density drastically reduced at the deeper depth. Tillers number/hill, plant height, panicle length, number of grains/panicle, grain and straw yield at different tillage practices significantly increased over control. The T3 (CP4) gave the highest plant height (95.93 cm) among all treatments. The highest grain yield (5969.25 Kg ha -1) was found under T6 (PT4) whereas the lowest yield (1451.03) was obtained in control treatment. The grain yield shows a highly positive significant relationship (r=0.993) with root mass density.
