    Characterization of Properties of soils of Jumar Nala Watershed
    (Birsa Agricultural University, 1987) Kumar, Ramesh; Singh, K.D.
    The area selected for the study is a part of Jumarnalavaterahed (Nagri village). The objective of this investigation is to study the physical and hydraulic properties of soils with a view to characterize upland, medium land and lowland and to the relationship between available moisture, and texture, waterstable aggregates, organic matter etc.. The result indicated that clay content, GMD and pH value increased with depth and only organic matter con tent decreased in all the three land situations i.e. land situation-I, land situation-II and land situation-III. The infiltration rate was highest (3.0 cm hr-¹) in land situation-I followed by land situation-II (2.4 cm hr¹) and land situation-III (2.0 cm hr ¹). The correlation studies showed a high positive significant relationship between 0.33 bar moisture per cent and silt, clay and silt+clay content (r = 0.75, 0.61** and 0.82* respectively). Similarly, high significant correlation coefficient was obtained between 15 bar moisture per cent and silt, clay and silt+clay content (r= 0.70, 0.76 and 0.88** respectively). The available water capacity (ANC) was (8-10) cn/60 cm depth for land situation-I where as it was (10-12) cm/60 cm depth for land situation-II and land situation-III. Available water capacity showed high positive significant correlation with silt, clay and silt+clay contents (r = 0.74**, 0.54 and 0.73, respectively). A sharp release of moisture between 0.33 and 1 bar ranged from 30.98 to 34.68 per cent of total available water per cent and about 10 per cent moisture was left after 10 bar suction.

    Development and Validation of Elisa Kit for Pregnancy Diagnosis in Cattle through Milk
    (Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2011) Kumar, Ramesh; Prasad, R.L.
    1. The Dot ELISA developed for first time is suitable for early pregnancy diagnosis which may be used with 77.27% accuracy. 2. Dot ELISA will give 100% accurate result for non pregnant cattle. 3. The reagents used during this technique is very less as compared to plate ELISA which might reduce the cost. 4. Before patenting of the kit further studies on simplicity of progesterone extraction from milk is suggested.
