Influence of Integrated Weed Management Practices on Weed Dynamics, Productivity and Nutrient Uptake of Rabi Maize (Zea mays L.)

Integrated Weed Management in Maize

Weed Composition in Maize (zea Mays L.) Fields under Smallholder Conservation Farming

Smallholder farmers in southern Africa have reported on increased labour requirements for hoe weeding due to high weed infestations in conservation farming (CF) fields. However, CF proponents claim that weed pressure and labour requirements for weeding decrease within the first three years under the recommended CF practices. An observational study was carried out during the 2008/09 cropping sea...

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 ...

Maize (Zea mays L.).

Agrobacterium tumefaciens-mediated transformation is an effective method for introducing genes into maize. In this chapter, we describe a detailed protocol for genetic transformation of the maize genotype Hi II. Our starting plant material is immature embryos cocultivated with an Agrobacterium strain carrying a standard binary vector. In addition to step-by-step laboratory transformation proced...

Effects of manure, municipal waste compost and nitrogen on weed communities in corn (Zea mays L.)

A two year field experiment was carried out to evaluate the effects of municipal waste compost (C), composted cattle manure (M), and nitrogen (N) on growth and composition of weeds in a corn field in Shiraz using a split-split plot design with 3 replicates. Visual inspection of the plots showed that the manure treatments neither introduced new weed species nor increased weed density more than t...
