Performance of short duration groundnut (Arachis hypogaea L.) variety (TG 51) as influenced by nutrient management strategy under new alluvial zone of West Bengal

To study the effect of nutrient management strategy on production potentiality of short duration high yielding summer irrigated groundnut variety TG 51, field experiments were conducted during summer seasons of 2011 and 2012 at Bidhan Chandra Krishi Viswavidyalaya, West Bengal. Results revealed that, application of 100% RDF + 7.5 t/ha FYM as basal increased growth and yield attributes that led to significantly higher productivity (pod yield 3320 kg/ha) besides enrichment of soil available nutrients after harvest of the crop. Pod yield decreased with further increase in NPK fertilizer above 100% RDF. However, maximum haulm yield (3979kg/ha) was recorded with 150% RDF + 7.5t/ha FYM as basal. Maximum net return: cost ratio (3.43) was found with 100% RDF which was closely followed by that of 100% RDF + 7.5 t/ha FYM.
