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. Application of Fenoxaprop–p-ethyl 54 gm a.i. ha-1 as early post emergent at 20 DAP recorded significantly higher growth parameters viz; plant height (64.4 cm), number of shoots plant-1 (8.03), number of leaves plant-1 (21.0), leaf area (724 cm2), leaf area index (0.60), total dry matter plant-1 (7.30 g) over weedy check (48.67 cm, 4.33, 10.33, 400 cm2, 0.33 and 4.84 g, respectively). Application of Fenoxaprop–p-ethyl 54 gm a.i. ha-1 as early post emergent at 20 DAP recorded significantly higher number of tubers plant-1 (4.30), tuber weight plant-1 (250.50 g) and tuber yield (19.77 t ha-1) which was on par with Quizalofop–p-ethyl (4.07, 247.37 g and 18.93 t ha-1, respectively) except weed free check.
Key words: Potato, Weed, Fenoxaprop–p-ethyl, Quizalofop–p-ethyl, growth, yield, grading.
