Study on yield maximization of wheat with equitable use of agri-inputs and weed management practices under restricted irrigation condition

The field experiment was entitled with “Study on yield maximization of wheat with equitable use of agri - inputs and weed management practices under restricted irrigation condition” was conducted during rabi 2021-22 and 2022-23, at student’s Instructional farm, C.S.A. University of Agriculture and Technology, Kanpur Nagar (U.P.). The soil of the experimental plot was sandy loam in texture. The experiment was laid out in Factorial Randomized Block Design (RBD) with three replications, assigning 26 treatments combination, four fertility levels F₁- Absolut control, F₂- RDF (150:60:40 NPK Kg/ha), F₃- RDF (75:60:40 NPK Kg/ha) + 2 spray of Nano Urea (4ml/ litter), F₄- RDF (150:60:40 NPK Kg/ha) + 2 spray of Nano Urea (4ml/ litter) and five weed management practices W₁- Weedy check, W₂- Metsulfuran methyl 10% + Carfentrazone ethyl 40% DF @50g ha^-1, W₃-Pyromaxsulfuron 85% wc @ 800 ml ha^-1, W₄- Flumioxazin 50% sc @ 250 ml ha^-1, W₅- Two hand weeding at 20 and 40 DAS. The results of the experiment concluded that the there was no any effect of plant population on growth. Highest growth was recorded in RDF (150:60:40 NPK Kg/ha) + 2 spray of Nano Urea (4ml/ litter) (F₄) treatment and two hand weeding at 20 and 40 DAS (W₅) treatment. This is revealed by Relative growth rate highest growth was recorded at sowing to 30 DAS.
