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 growth and yield of potato (Solanum tuberosum L.) the soil of experimental site is red sandy loam in texture, neutral in reaction and medium in available nitrogen, phosphorus and potassium. The experiment was laid out in a RCBD with seven treatments replicated thrice. The investigation revealed that, among different herbicides, lower sedge density and dry weight was recorded by Metribuzin 500 g a.i. ha-1 as pre-emergent (20.5 m-2 and 9.0 g m-2, respectively). Whereas application of Fenoxaprop–p-ethyl 54 gm a.i. ha-1 as early post emergent at 20 DAP recorded significantly lower grasses, broad leaved and total weed density (15.3, 24.7 and 62.0 m-2, respectively), weed dry weight (7.9, 10.3 and 28.1 g m-2, respectively), lower weed index (5.9 %), higher weed control efficiency (73.3 %). This treatment registered significantly higher tuber yield (19.77 t ha-1) which was on par with Quizalofop–p-ethyl (18.93 t ha-1) and significantly lower tuber yield was recorded in weedy check (14.00 t ha-1).
