摘要

The field experiment was conducted during winter seasons (Rabi) of 2018-19 and 2019-20 at Agricultural Research Station, Navgaon (Alwar), S.K.N Agriculture University, Jobner, Jaipur (Rajasthan) India, to identify effective and economic weed management practices in standing Chandrashoor (Lepidium sativum Linn.) crop. The soil of experimental field was sandy loam in texture, low in organic carbon, low in available nitrogen, medium in phosphorus and potassium with alkali in pH. The experiment was laidout in a randomized block design with seven treatments and replicated thrice. The crop was sown as per the package of practices recommended for zone IIIB of Rajasthan. The treatments tested incudes: post-emergence application (PoE) of quizalofop-p-ethyl50 g/ha, fenoxaprop-p-butyl 100 g/ha, imazethapyr 75 g/ha, imazethapyr (35%) + imazamox (35%) (ready-mix) 100 g/ha, imazethapyr (2%) + pendimethalin (30%) (ready-mix) 2.5 kg/ha; weedy check and weed free. The fenoxaprop-p-butyl 100g/ha PoE recorded significantly higher seed yield of 678 kg/ha in 2018-19 and 693 kg/ha in 2019-20 due to greater weed suppression and lowest weed index. It was at par with quizalofop-p-ethyl 50 g/ha PoE at 30 DAS. However, weed free, by hand weeding twice, recorded higher seed yield and was significantly superior economically over the rest of the weed management treatments.
