Abstract:
The present investigation entitled “Effect of weed management practices on yield, nutrients uptake and available nutrients in potato under partially reclaimed soil” was carried out at Main Experiment Station, Vegetable Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi season 2019-2020. The experiment was laid out in Randomized Block Design with three replications. There were eight treatments viz., T1 control (Recommended dose of N: P2O5 K2O @ 150:100:120 kg ha-1), T2 (T1+Eucalyptus leaf @ 5t/ha), T3 (T1+Mahua leaf @ 5t/ha), T4 (T1+Rice straw @ 5t/ha), T5 (T1+Water hyacinth @ 5 t/ha), T6 (T1 + Neem leaf @ 5t/ha), T7 (T1+Metribuzin @ 0.35 kg/ha PE), T8 (T1+ Two hand weeding at 20 and 40 DAS). The soil of the experimental field was silt loam in texture, having Ph 8.2, organic carbon 3.1 g/kg, available N 142 kg/ha, available P 14.9 kg/ha, available K 241.0 kg/ha and available Zn 0.41 ppm. The potato variety Kufri Neelkanth was sown on 16/11/2019 at spacing 60 cm x 20 cm. Leaf mulches (Eucalyptus, Mahua, Rice straw, water hyacinth and neem @ 5t/ha and Metribuzin @ 0.35 kg/ha PE (pre emergence) were applied as per treatment. Among the various mulches, water hyacinth @ 5t/ha was found better on yield nutrients uptake and available nutrients in Soil.
