A reduced herbicide rate with hand-weeding (HW) can act as a safer and sustainable approach for weed control. field study was conducted at CSIR-IHBT, Palampur, India during 2018 2019 to analyze the efficacy of herbicides in combination manual weeding on control yield wild marigold (Tagetes minuta L). The experiment laid 12 treatments, consisting two dosages prescribed rates (R) pendimethalin, i...
An experiment was conducted during 2020–21 at the Rani Lakshmi Bai Central Agricultural University, Jhansi, Uttar Pradesh to study effect of tillage, rice (Oryza sativa L.) residue, weed control and N fertilizer levels on weeds, growth yield wheat (Triticum aestivum L.). Weed infestation in zero-tillage (ZT) significantly lower (16.7–27.6%), more so when rice-residue retained soil surface compa...
Navua sedge (Cyperus aromaticus) is threatening crops, pasture species and natural ecosystems in Pacific Island countries northern Queensland, Australia. To aid future management efforts of this exotic invasive weed, research was conducted to understand the soil seed bank dynamics pastures invaded by sedge. Six grazing properties were chosen across two landscapes, coastal inland/upland, with ar...
Chemical-dependent weed control has led to the evolution of herbicide-resistant weeds and pollution arable land water systems, posing a great threat food security environmental safety. For first time, we developed simple management regime ecologically deplete seed bank under wheat-rice cropping system, which in turn allowed reduction frequency conventional herbicide applications while sustainab...
A field experiment was conducted in the years 2008– 2010 at the Research Station of the Faculty of Agricultural Sciences, University of Life Sciences in Lublin, on brown soil with slightly acidic pH and average abundance of copper, zinc, manganese, and iron. The experiment was set up in a randomized split-plot design with four replications, with two methods for controlling weed infestation: I. ...
this study was undertaken to investigate the effect of long-term reduced tillage on grain yield, grain quality, and weed infestation of spring wheat. the experimental variables were three tillage systems: (a) conventional tillage (ct): shallow ploughing (10-12 cm) and harrowing after harvest of the previous crop, ploughing (25-30 cm) in the autumn; (b) reduced tillage (rt): only a cultivator (1...
