IMPACT OF SEED INFECTION LEVEL AND PLANT DENSITY ON THE QUALITY YIELD OF WHEAT CV. SHATABDI (Pages : 19 - 33)

An experiment was conducted during November 2010 - April 2011 to find out the influence of infected (Bipolaris sorokiniana) seed and plant population density on the spread of leaf blight and yield of wheat. The seed infection level and the population density influenced the pathogenic activities through creating microclimate variability that modify the leaf blight/spot development by Bipolaris sorokiniana of wheat, six different seed infection levels viz. T1 = 0%, T2 = 5.1-15%, T3 = 15.1-25%, T4 = 25.1-35%, T5 = 35.1-45%, T6 = 45.1-60% were tested. Population density and seed infection levels had significant influence on plant growth parameters and yield and yield contributing character of wheat cv. Shatabdi. Population density 300 seeds/ m2 showed best performance in case of grain and straw yield. The highest grain yield (2.64 t/ha) and straw yield (6.87 t/ha) was obtained from 300 seeds/m2 population density. The Highest grain yield (3.14 t/ha) was also produced from 0% seed infection treatment, whereas, 45.1-60% seed infection treatment produced the lowest grain yield (1.04 t/ha). The highest straw yield was observed with 300 seeds/m2 and the lowest from 200 seeds/m2. The influence of the development of leaf blight disease of wheat by Bipolaris sorokiniana with increased plant density attributed to favorable microclimate produced in the field condition.Download
