  Experiment was conducted to increase cropping intensity through soil water management and conservation practices. Transplanted rainfed aman rice is grown in Cropping patterns studied during 2000-01 were rice-legume-legume and rice-fallow-fallow, using early maturing drought tolerant crop varieties and local rice. Tillage treatments were imposed during land preparation. Mulch treatments were also imposed in legume rotations. Newly introduced varieties, BRRIdhan 33 and BINAdhan 4, were earlier by 25 and 15 days, respectively, compared with the local rice Sarna. The early harvest of rice varieties left enough residual moisture due to tillage amendments and mulch applications. The available profile soil moisture left was able to meet up about two-third of the water requirement of chickpea (cv. BINAsola2 and Hyprosola). Pre-sowing irrigation, tillage, mulch practices and little rain contributed to successful production of mungbean cv. BINAmoog 2 after chickpea. A reasonable yield of all the crops was obtained compared with the national average yield. The introduction of chickpea and mungbean in the cropping pattern resulted the cropping intensity from 100 to 300%. The altered cropping pattern (rice-legume-legume) evaluated with the existing one (rice-fallow-fallow) resulted the net return of t 37144.00 to t 55406.00 with BCR value of 1.94-2.40. The achievement of a new cropping pattern was only possible due to introduction of early drought tolerant crop varieties, soil water management and conservation practices.

  A total of 29 Staphylococcus aureus strains isolated from human, animals and their environment were subjected to genotypic analysis on the basis of coagulase gene polymorphism. The coagulase gene was amplified using a pair of oligonucleotide nested primers. Presumptive phenotypic identification of the strains showed production of free and bound coagulases, production of acetion, anaerobic utilization of mannitol with acid production. PCR-amplified coagulase genes of S. aureus revealed different pattern in base pair lengths and number of amplified bands. There were no obvious specific PCR pattern for all types of isolates thus, genotypic clustering correlated to human, animal and environmental isolates was not passable. Given the specificity of the coagulase gene, the isolates were thus confirmed to be belong to the coagulase positive S. aurueus. Out of 29 PCR-amplification isolates, 21 produced a single band while 8 isolates produced two bands. The length of the amplicon ranged from 430 to 1000 bp. Amplicons of the 21 isolates were thus categorized as 670, 930, 950 and 1000 bp. In conclusion, Amplification of coagulase gene is useful in confirmation of coagulase gene positive S. aurueus.
