Abstract
A field experiment on “Integrated weed management in irrigated wheat (Triticum aestivum L.)” was conducted at Chandigarh University, Gharuan (Mohali) during rabi 2020-21 to investigate the effects of different levels of Farmyard manure on yield of wheat varieties. The soil of experimental field was clayey loam and neutral in reaction. The soil was low in organic carbon and available nitrogen and medium in available potassium and phosphorous. The experiment was laid out in randomized block design with eleven treatments, (T1) control, (T2) one interculture at 30 DAS, (T3) isoproturon @ 0.75 kg a.i. ha-1 at 30 DAS+ one interculture at 50 DAS. (T4) isoproturon @ 0.75 kg a.i ha-1 + 2, 4-D @ 500 ml ha-1 at 30 DAS. (T5) Sencor @ 250 g ha-1 at 30 DAS. (T6) isoproturon @ 0.75 kg a.i. ha-1+ 2,4-D @ 500 ml ha-1 at 30 DAS + one interculture operation at 50 DAS with medium cultivar. (T7) Sencor @ 250 g ha-1 at 30 DAS + one interculture at 50 DAS. (T8) Pumasuper @ 800 ml ha-1. (T9) Pumasuper @ 800 ml ha-1at 30 DAS + one interculture at 50 DAS. (T10) FIRBS with 3 rows. (T11) FIRBS with 3 rows + one interculture operation with medium cultivar. A significant improvement in growth and yield attributing characters were recorded with the application of Sencor @ 250 g ha-1 at 30 DAS + one interculture at 50 DAS over the rest of the treatments. Isoproturon @ 0.75 kg a.i. ha-1+ 2,4-D @ 500 ml ha-1 at 30 DAS + one interculture operation at 50 DAS with medium cultivar was next in superiority and produced higher grain yield than rest of the treatments. FIRBS with 3 rows + one interculture at 30 DAS and FIRBS with 3 rows alone did not prove effective in controlling weeds as compared to chemical weed management method alone or in integration with interculture at 50 DAS.
