Effect of potassium nutrition on yield, quality and economics in groundnut (Arachis hpogaea L.) in a Vertisol

Author(s): Ummesalma Sanadi, KK Math, Bidari BI and Basavaraj S Yenagi
Abstract: A field experiment was conducted during kharif, 2016 at the Main Agricultural Research Station, Farm, University of Agricultural Sciences, Dharwad. The experiment was laid with twelve treatments replicated thrice in Randomized Block Design. The soil reaction was near neutral and electrical conductivity was under safer limit with clay texture. Pod yield in groundnut was not significantly influenced by different potassium nutrition treatments. However, split application of 150 per cent recommended dose of potassium (RDK) through muriate of potash in combination with 2 per cent foliar spray of potassium sulphate on 60 DAS recorded higher pod yield (3617 kg ha-1) closely followed by basal application of 150 per cent RDK along with 2 per cent foliar spray of potassium sulphate. The control with recommended package of practices recorded the lowest pod yield (3009 kg ha-1). Split application of 150 per cent RDK along with foliar spray of SOP at 2.0 per cent significantly enhanced oil (47.84 %) and protein (37.98 %) contents in kernel closely followed by the application of basal dose of 150 per cent RDK plus 2 per cent foliar spray. RPP recorded the lower values (oil- 45.10%, protein- 35.53%). The treatment with 150 per cent RDK through muriate of potash in split (half as basal + half at 30 DAS) plus 1 per cent foliar spray through potassium sulphate at 60 DAS (T8 ) recorded higher B:C ratio (2.65) whereas control recorded the lowest B:C ratio (2.28).
