A study was undertaken on phenotypic characterization of different isolates of Bipolaris sorokiniana isolated from the different varietal trials and nurseries of barley at the agricultural research farm, Institute of Agricultural sciences, Banaras Hindu University. The isolation was performed by transfer of single spore of the pathogen from diseased leaf in Potato Dextrose Agar media (PDA) under aseptic condition. The experiment revealed five groups of isolates on the basis of colony colour, morphology and number of spores. It was found that (42.2%) of the isolates were black in colour with profuse sporulation and suppressed type growth, (35.71%) of the isolates were greyish in colour and (21.42%) of the isolates possessed whitish colony with full plate growth and lower sporulation. The size of conidia ranged from 24 × 13µm to 36 × 14µm in size, while the number of spores per mm2 of colony varied from 20.36 to 162.77.

Jharkhand agricultural system is mainly dependent upon the weather conditions and the monsoon rainfall during the Kharif season. The state agricultural system is lagging behind because of low productivity, monocropping, erratic rainfall, and frequent dry spells. In addition to that, there is also a change in the weather pattern which will have a more significant negative impact on production and productivity of crops in the state, if the farming community continues with their indigenous practices. Ragi is a drought-tolerant and highly nutritional crop which has an economic value and productivity in the range of major cereals. The present study was conducted to find out the change in rainfall and temperature pattern of Ranchi as per the data available from 1950. Ragi variety, Birsa Madua-1, was tested for its productivity and economics in four villages of Ranchi under the weather conditions of Kharif season of 2018. It was concluded that there is a shift of rainfall in the district and rainfall period of Kharif crops is decreasing. There is also an increase in temperature and potential evapotranspiration. Ragi showed adaptability and stability even under the changing conditions with a B:C ratio of 2.28. Thus, it can be concluded that farmers should be made aware of the changing weather pattern and encourage them to cultivate ragi in order to combat the changing scenario.
