Abstract

Chickpea is a popular legume crop in Asia and Africa's semi-arid regions with modest production gains, because of several biotic and abiotic factors. Among the different diseases, collar rot of chickpea is a major limiting factor in central India. In the present investigation, three sowing dates were evaluated with four different seed treatments in three chickpea varieties for management of collar rot of chickpea. Significant effect of date of sowing along with impact of seed treatment were recorded in inhibiting the collar rot incidence. Among the different varieties minimum incidence of collar rot was recorded in JG 14 followed by JG 36 and JGK 1 in all the seed treatments and date of sowing. Further, among the different seed treatment practices, minimum collar rot incidence of 12.94%, 9.97% and 6.73% was recorded in seed treatment with Rhizobium + PSB @ 10 ml/kg seed during sowing in first, second fortnight of November and first fortnight of December respectively in chickpea variety JG 14. The same treatment showed the maximum effect in inhibiting the incidence of collar rot in other two studied varieties namely JG 36 and JGK 1. Among the different dates of sowing, the incidence of collar rot was recorded highest during early sowing and it kept on decreasing by delaying the sowing. The maximum mean incidence of collar rot of 18.76% was recorded with sowing during the first fortnight of November followed by sowing during second fortnight of November (14.38%) and minimum of 8.77% in sowing during first fortnight of December.

Conclusion

Overall scenario across three varieties, three date of sowing and four seed treatments revealed that late sowing during first fort night of December in combination with seed treatment with Rhizobium + PSB @ 10 ml/kg seed prior to sowing was recorded as best treatment for control of collar rot of chickpea irrespective of variety used.
