The effect of weed management that targets the seed stage on subsequent life stages is largely unknown. Post-dispersal predation reduces number seeds from soil surface before contribute to seedbank. Density-dependent processes can mitigate in stages. In this study, we tested if (i) targeting affects seedling stage; (ii) density-dependent mortality partly compensates abundance; and (iii) magnitu...

Sixtyfour Indian barnyard millet genetic resources were studied to assess the extent of divergence for 18 quantitative traits using Mahalanobis D2 Statistic. evaluated during kharif, 2020 in a lattice square design, replicated twice at Regional Agricultural Research. Based on Tocher’s method, entire materials separated into eight distinct and non-overlapping clusters suggesting availability div...

Echinochloa crus-galli, a problem weed in rice fields, has the rare ability to germinate and to grow in a totally oxygen-free environment. After 7 days growth in the light or dark under N(2), E. crus-galli var. oryzicola produces a 2- to 3-centimeter nonpigmented shoot.Ethanol, malate, and lactate were measured in seeds germinated under N(2) and air, and compared with changes in the activities ...
