| dc.description.abstract | A field experiment was conducted to study the “Influence of pre-emergence herbicide mixtures on growth and yield of potato (Solanum tuberosum L.)” at ICAR Krishi Vigyana Kendra, Hadonahalli, Doddaballapura Taluk, Bengaluru Rural District during kharif 2020. The results revealed that lower total number of weeds (7.67 m-2) and weed dry weight (11.75g m-2) was observed with metribuzin 11.25% + pendimethalin 29.75% ZC @ 2500 ml ha-1 which was at par with twice hand weeded plot (5.56 m-2 and 9.71g m-2 weeds and weeds dry weight respectively). Higher weed control efficiency (93.55%), taller plants (70.15 cm), plant spread (NS: 55.08 cm and E-W: 60.46 cm), maximum number of leaves (37.61), leaf area (22.28 cm2), number of haulms per plant (2.73), number of tubers per plant (6.78), weight of tubers per plant (593.9), higher TSS (5.6 °Brix), minimum number of days for 50 per cent flowering (29.33 days), tuber yield (34.21 t/ha), marketable yield (29.57 t/ha), maximum N, P and K uptake by potato plant (223.73, 16.91 and 271.79 kg/ha N, P and K respectively) and minimum uptake by weeds (8.27, 1.73 and 7.20 kg/ha N, P and K respectively) noticed with metribuzin 11.25% +pendimethalin 29.75% ZC at 2500 ml ha-1 which was on par with hand weeding @ 20 and 40 DAP. The higher B:C ratio (2.61) was noticed with metribuzin 11.25% + pendimethalin 29.75% ZC at 2500 ml ha-1 as compared to other treatments. | en_US |
