Abstract:
Groundnut (A. hypogaea L.), the king of oilseeds is an auxiliary food crop with greater economic and nutritive value. India is the largest producer of groundnut and in India, Gujarat ranked first in terms of area and production of groundnut. In Gujarat, the Saurashtra region covers a wide area under production and is known as the heart of Gujarat as well as of India for groundnut production. In the present study, the pathogen associated with stem and pod rot of groundnut was isolated from different groundnut growing areas of Saurashtra and confirmed by morphological observation as Sclerotium rolfsii. In vitro efficacy of seven water soluble soil amendments was tested against the pathogen. Among all the soil amendments tested, four of them viz., farmyard manure, vermicompost, cotton seed cake and castor cake showed complete inhibition of mycelial growth at all tested concentrations. Additionally, goat manure and karanj cake showed 77.69 and 57.44 percent mean inhibition of mycelial growth, respectively. However, goat manure and karanj cake gave complete inhibition of radial growth at concentrations of 5, 7.5 and 10 percent. The lowest inhibition was recorded by neem cake with 49.20 percent mean mycelial growth inhibition.
