Abstract

Chickpea (Cicer arientinum L.) is an important annual legume crop of the family Fabaceae. Different abiotic and biotic agents affect adversely chickpea productivity around the world. Wilt disease is a major constraint to chickpea production due to the occurrence of wilt of chickpea causal organism of wilt Fusarium oxysporum f. sp. ciceri (Padwick) synd. and Hans. It produces microconidia, macroconidia, and chlamydospores. Among all surveyed districts, disease incidence ranged from 9.17 to 23.40 per cent with an overall mean of 17.05 per cent in Rajasthan. The highest mean disease incidence was observed in Ajmer district (23.40%) followed by Pali (21.10%), Jaipur (20.16%), Bhilwara (17.86%), Tonk (17.73%), Sikar (15.81%), Bikaner (11.19%), and lowest was in Churu district (9.17%). Not a single location of surveyed districts was completely free from the disease incidence

Conclusion

The wilt of chickpeas is one of the important limiting factors in the successful cultivation of chickpea in different parts of Rajasthan. In the present study, an attempt was made to investigate various important aspects of the disease. A survey was conducted in eight districts of Rajasthan to know the incidence of disease on the crop. The highest disease incidence was assessed in Ajmer (23.40%) while the least in Churu (9.17%) location. Under natural conditions, the disease symptoms first appeared on roots showing reddish to brownish discoloration. Further, the disease progressed upwards showing yellowing of the lower leaves progressing upwards
