Abstract
The field and pot culture experiments were conducted at Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai during 2016-2018 and laid out in a split-split plot and completely randomized block design replicated thrice. Predominant weed species observed in the field included grasses like Chloris barbata, Cynodon dactylon, Dactyloctenium aegyptium and Echinochola crusgalli; Cyperus rotundus and Cyperus iria under sedges and broad-leaved weeds like Acalypha indica, Amaranthus viridis, Boerhavia diffusa, Commelina benghalensis, Cleome viscosa, Convolvulus arvensis, Eclipta alba, Euphorbia hirta, Portulaca oleracea, Phyllanthus niruri and Trianthema portulacastrum. During both the years of experiments, the results revealed that minimum tillage with 30% daincha residue and PE application of atrazine followed by one hand weeding at 30 DAS along with 75% RDF (NPK) + vermicompost + azhophos recorded significantly lesser grasses, sedges and broad leaved weeds density, dry weight and higher weed control efficiency (WCE) in maize. In case of black gram, conventional tillage with PE application of Pendimethalin followed by one hand weeding at 20 DAS and 75% RDF (NPK) + vermicompost + rhizobium attained the lowest weed density, dry weight and higher WCE. Soil weed seed bank studies showed that, conservation tillage with 30% crop residue retention and PE application of herbicides influenced different weed flora occurrence in the maize based conservation agriculture system.
