Effect of macro and micro-nutrients on the development of leaf blight of groundnut caused by Drechslera spicifera

摘要

Groundnut (Arachis hypogaea L.) is an important oilseed crop in India. Leaf blight of groundnut (Drechslera spicifera (Bain) Van Arx) is widely occurs on crop grown in sandy soils at Rajasthan, and causes considerable losses in crop production when climatic conditions are dry and temperature remains high. The availability of nutrients to the host plants greatly influences the development and severity of disease. Hence, an attempt has been made to study the effect of macro and micro-nutrients on disease severity and pod yield of groundnut.
