Groundnut belongs to family Leguminosae (Fabaceae) sub-family Papilionoideae. Five states namely Andhra Pradesh, Gujarat, Karnataka, Rajasthan and Tamil Nadu account for about 80% of the total groundnut area and production of the country. Gujarat alone contributes about 35% of the total production of groundnut. Groundnut is a typical crop which requires a long warm growing season while water logging, drought and cold weathers are extremely detrimental to its growth.Soils that are well drained, light coloured, loose, fertile, sandy loam, rich in calcium and moderate organic matter with pH ranging from 5.0 to 8.5 is ideal for groundnut cultivation
Problems faced by farmers
Major Concern for Groundnut farmers are leaf spots (early leafspot and late leaf spot)commonly called as “Tikka” disease cause nearly complete defoliation and yield loss up to 50 per cent or more depending upon disease severity.
