Selectivity of chemical weed control systems in conventional cotton

Effect of living mulches and conventional methods of weed control on weed occurrence and nutrient uptake in potato

The aim of the study was to determine the biomass, abundance and species composition ofweeds, as well as macroelement uptake in potato weeded using mechanical, mechanical–chemical and mechanical control combined with the sowing of living mulches of white mustard,common vetch, Persian clover and tansy phacelia. Abundance and biomass of the weeds was themost effectively limited by the mechanical ...

Weed Control and Yield Comparisons of Twin- and Single-Row Glyphosate-Resistant Cotton Production Systems

A 2-yr field study was conducted during 2007 and 2008 at Stoneville, MS, to determine the effect of twin-row (two rows 38 cm apart on 102-cm beds) and single-row (on 102-cm beds) patterns and glyphosate POST applications with and without fluometuron + S-metolachlor PRE on cotton canopy closure, weed control, and lint yield in two cultivars (‘DP117B2RF’, early maturity, hairy leaf; ‘DP164B2RF’, ...

Effects of ridge and conventional tillage systems on soil properties and cotton growth

Cotton (Gossypium hirsutum L.) seeds are susceptible to low temperature and excess moisture in soil during seed emergence in years with high rainfall and low temperature in spring. Therefore, a two-year field experiment was carried out to evaluate effects of ridge tillage formed in autumn (RT-I), ridge tillage formed about a month before planting (RT-II) and flat conventional tillage (CT) culti...
