Soil conditions and root diseases

VII. Response of cotton plants to micro-element amendments and its relation to disease development

  • Published:
Proceedings / Indian Academy of Sciences

Summary

In the experiment conducted to study the response of cotton plants to micro-element soil amendments zinc and manganese were found to be beneficial for the growth of cotton plants. Boron, lithium and molybdenum were toxic.

Cent per cent. germination of cotton seeds was recorded in the control and all the treated soils except in the case of boron treatments. When the seeds were soaked in micro-element solutions prior to sowing in soil, only the nickel-treated seeds showed scanty germination.

Studies on the pathogenic potentialities ofFusarium vasinfectum on a susceptible variety of cotton showed that zinc was effective in reducing the wilt incidence, whereas manganese aggravated the incidence of wilt.
