Bovine mastitis caused by Staphylococcus aureus is a worldwide disease of high economic significance. These organisms possess many virulence factors allowing them to evade host immune system. In the present study, 28 S. aureus isolates from milk obtained from Holstein-Friesian (H-F) crossbred and Rathi (a native breed) cattle with clinical mastitis were characterized for their two virulence-associated genes: coa and spa. All the isolates were confirmed genotypically by 23S rRNA ribotyping in which a species specific amplicon of 1,250 bp was obtained. Polymorphism was recorded in coa and spa genes. The coa gene produced one amplicon in each isolate either of 510, 600, 710 or 850 bp size with more variability observed in the Rathi isolates. The AluI restriction endonuclease generated three and five RFLP patterns with isolates from H-F crossbred and Rathi cattle, respectively. The RFLP patterns obtained from similar amplicons in isolates from two breeds did not differ. PCR amplification of the X-region for spa gene yielded amplicons of seven different sizes: 206, 243, 262, 277, 292, 306 and 339 bp with calculated number of 7, 8, 9, 10, 10, 11 and 12 bp repeats, respectively indicating presence of highly pathogenic strains. Among all the spa types, four were common to both animal groups, one was unique to H-F crossbred cattle and two were unique to Rathi cattle. © 2012 Springer-Verlag London.

Chickpea stunt disease caused by Chickpea chlorotic dwarf virus (CpCDV) (genus Mastrevirus, family Geminiviridae) is the most important biotic stress affecting chickpea crops worldwide. A survey conducted on the incidence of stunt disease clearly revealed high incidence of the disease with severe symptom expression in both indigenous and imported genotypes. To manage the disease in a sustainable way, resistant genotypes need to be bred by adopting objective and precise assessment of the disease response of chickpea genotypes. At present, evaluation of CpCDV resistance is conducted on the basis of natural infection in the field, which is bound to be erroneous due to vagaries in vector population. To circumvent the above problems, we devised an agroinoculation technique that involves the delivery of viral genomic DNA through Agrobacterium tumefaciens. An objective scoring system assigning quantitative value to different symptoms has been evolved to assess the response of chickpea genotypes to CpCDV inoculation. Using the inoculation and scoring techniques, we screened 70 genotypes, which helped in differentiating field resistance that is more due to resistance to vector feeding than resistance to the virus. © 2013 Springer-Verlag Berlin Heidelberg.

Field experiment was conducted to workout the effect of different residual sodium carbonate (RSC) waters and organic manures on physicochemical properties, soil microbial biomass and yield of mustard in loamy sand soil during rabi seasons of 2006-07 and 2007-08. The treatments were: Four levels of RSC waters (2, 6, 9 and 12 mmol L-1) and five levels of organic manures (control, recommended dose of N fertilizer, 12 t FYM ha-1, 5 t poultry manure ha-1 and 4 t vermicompost ha-1). Result revealed that under application of 12 mmol L-1 RSC of irrigation water whereas the bulk density, pH, CEC and ESP increased significantly, saturated hydraulic conductivity, EC and organic carbon of soil at harvest exhibited a significant decreased. The soil biological activity like build-up and losses of microbial biomass C, N and P were reduced significantly, while, turnover rate of microbial biomass increased with all the levels of RSC of irrigation water; difference was not significant among water up to 6 mmol L-1 of RSC. The seed and stover yield of mustard also decreased significantly with increasing levels of RSC. Application of organic manures significantly reduced the saturated hydraulic conductivity; moisture retention at 33 kPa, and 1500 kPa; and available water and organic carbon content of soil. The bulk density, pH, ESP, turnover rate of biomass C, N and P decreased significantly, while CEC of soil at harvest increased significantly with application of 5 t poultry manure ha-1. Significant increase was noted in seed and stover yield of mustard under all the organic manures over control and recommended dose of N fertilizer.

Precision agriculture is an integrated agricultural management strategy where farmers can adjust input use and cultivation methods - including seed, fertilizer, pesticide, and water application, varietals selection, planting, tillage, harvesting - according to varying soil, crop and other field conditions. Advances in telecommunications technologies continue to help make farm life easier and to improve production efficiencies. The convergence of sensing, computing and communication technologies for agricultural applications has led to the creation of a new technology - Agricultural Infotronics Systems (AIS), which is a framework of wirelessly networked on-farm production data management systems to collect, process, and transmit the "ready-to- use" site-specific production data to the user on the machinery while performing the field operation. Thus, telecommunication technology is the backbone of precision agriculture. Precision farming involves integrated technologies such as GPS, GIS, remote sensing, and Variable Rate Technology (VRT), crop models, yield monitors and precision irrigation. In brief, precision agriculture refers to tailoring crop and soil management practices according to variation in crop and soil conditions within each field. This paper describes shortly about precision farming and its management.

Studies were made using organic fertilizers, inorganic fertilizers, biofertilizers, nutritional supplement and a bioregulator on the growth and yield attributes of mustard crop and on the appearance of diseases. The use of biofertilizers (Azotobacter and PSB) and Trichoderma along with the recommended doses of fertilizers enhanced the plant growth, improved yield and revealed lesser incidences of Alternaria blight and white rust diseases. In another trial, organic manure resulted better growth, enhanced yield and reduced disease incidences in mustard crop. Plant growth and yield of mustard also promoted by basal use of elemental sulphur as a nutritional supplement, spray of thiourea (0.1 %) at 50% flowering stage of the crop, along with the adoption of recommended doses of fertilizers (ie NPK, 80:40:40 kg/ha).
