| Abstract: |
Field experiments were conducted in 1998 and 1999 to determine the losses in grain yield due to finger blast caused by Pyricularia grisea in different growth stages of fingermillet CV GE 5001. The trials were planted during 2"d week of July and heading took place on 90 d after seeding in both years. Crop stage at which finiger infection took place on 10, 17, 24, 31 and 38 d after heading were considered as 5 treatments replicated 6 times in a randomized block design. Yield and yield components were significantlyinfluenced byfi nger blast 11-·hen infectiont ook place in different stages/days after heading (DAH). The treatments which involved finger infection at early flowering stage (1 0 DAH) had highest decrease in finger length, grain number, grain yield and test weight (14. 4, 56.2, 74.6 and 45.4%) respectively as compared to finger infection on 38 DAH Thetreatments in which disease· appeared on 17, 24 & 31 DAH had similar effects on. the yield attributes under investigation. When finger were infected at later stages of grainfilling i.e. 31 & 38 DAH, similar effects but decrease in the reduction of grain yield and yield components were observed. There existed a· strong linear relationship (R2=0. 99,0.93, 0.99 & 0.98) betweenfiniger·length, grain number, grain yield and test weight and finger age at infection. As the age of fingers increased · reduction in yield & yield attributes due to finger blast decreased. The results suggest that finger infection at later ·stages of grain development (31 & 38 DAH) will not have much effect on finger length, grain number, grain yield and test weight. |
