Influence of Different Herbicide Levels on Nutrient Removal by Weeds and Uptake by Potato (Solanum tuberosum L.)
Journal Title: International Journal of Plant & Soil Science - Year 2017, Vol 20, Issue 2
Abstract
A field experiment was conducted during kharif 2016 at College of Agriculture, Hassan, University of Agricultural Sciences, Bengaluru to evaluate different pre and post emergent herbicides on nutrient removal by weeds and uptake by Potato (Solanum tuberosum L.) the soil of experimental site is red sandy loam in texture, neutral in reaction and medium in available nitrogen and potassium, high in available phosphorus. The experiment was laid out in a RCBD with seven treatments replicated thrice. The investigation revealed that, among different herbicides, lower removal of N, P2O5 and K2O by weeds were recorded by application of Fenoxaprop–p-ethyl 54 g a.i. ha-1 as early post emergent (12.26, 4.12 and 11.47 kg ha-1) which was on par with the application of Quizalofop–p-ethyl 30 g a.i. ha-1 as early post emergent (13.58, 4.61 and 12.53 kg ha-1). Significantly higher total nutrient uptake by potato were recorded by (91.15, 30.75 and 94.70 kg N, P2O5 and K2O ha-1 at harvest, respectively) by Fenoxaprop–p-ethyl 54 g a.i. ha-1 as early post emergent, closely followed by Quizalofop–p-ethyl 30 g a.i. ha-1 as early post emergent (89.47, 29.50 and 93.12 kg N, P2O5 and K2O ha-1 at harvest, respectively).
