A Thesis titled “Eco- friendly management of Fusarium wilt of Chickpea (Cicer arietinum L.)” was submitted in partial fulfillment of the requirement for the award of the degree of Doctor of Philosophy in Agriculture Plant Pathology by Madhumita Pandey.
Chickpea is the most important pulse crop among the major Rabi pulse of India. Fusariums wilt which is caused by Fusarium oxysporum f.sp. ciceri is considered to be the most devastating disease of this crop. Survey for the assessment of chickpea wilt disease was conducted during 2012-14 in chickpea growing areas of Allahabad District. In this survey maximum Fusarium wilt disease incidence (66%-57.7%)) was recorded in Jarar and lowest was in Naini and Jorwat (11.75%) in the cropping season 2012-14. The general inadequacy of chemical fungicides to tackle Fusarium wilt in chickpea, has lead to the search for ecofriendly management to these disease. Twenty isolates of Pseudomonas fluorescens were isolated from chickpea field and evaluated against Fusarium oxysporum f.sp. ciceri in vivo and in vitro. Out of twenty isolates five isolates PF4- (89.45%), PF-13(86.76%), PF- 18(90.04%), PF-19(84.49%) and PF- 20(83.89%) were showing highest percentage inhibition of radial growth Fusarium oxysporum f.sp. ciceri in dual culture. Among organic manure highest reduction in mycelial growth was found in Neem cake (68.06%). In vivo the highest germination percentage were found in (98.40 %-97.43%) in PF -19. Pseudomonas fluorescens isolates (PF- 18) were showing significant reduction in wilt incidence (82.56%- 79.97%) at 30 DAS, (70.88%-70.51%) at 60 and (73.40%-72.35%) at 90DAS respectively during (2012-14). Maximum shoot length (cm) (15.73, 25.46 and 44.10),(15.93,35.93 and 45.36) and root lengths (7.46, 9.82 and 13.36), (6.52, 10.63, and 13.56) at 30, 60 and 90 DAS were recorded in PF-20. The dry shoot and root weight significantly increase in isolate PF18 and isolate PF-20. The highest number of pods per plant (70.30 and 73.03) and yield (912.6 and 996.0 kg) were observed in isolate PF-18. Among organic manure and improved cultural practices, highest germination percentage (96.26% and 97.16%), reduction in wilt incidence (78.91, 74.91 and 78.91) ,(78.91,69.70 and 72.23) in 2012-14 at 30,60 and 90 DAS were recorded in Soil solarization. In growth parameter maximum shoot-root length and dry shoot –root weight were significantly increased in Neem cake and in Soil solarization. Highest numbers of pods/plant (63.60 and 64.13), (61.10 and 62.16) and maximum yield (982.0kg and 987.3kg) (870.3 kg and 881.3 kg) were recorded in treatment soil solarization and Neem cake respectively in 2012-14. |
