Wastewater sources contain enormous amounts of nutrients for plant growth. This study aimed to define the metal accumulation in goosefoot (Chenopodium album L.) wastewater use agricultural irrigation and evaluate risks this human health. The present research was performed field conditions Khushab, Pakistan. Cd, Cu, Cr, Fe, Zn, Ni, Mn concentrations were determined with analysis using Atomic Abs...

Effective weed management depends on correct control timing, which seedling emergence dynamics. Since soil temperature and moisture are the two main factors that determine germination, hydrothermal time model can be used to predict their emergence. The aim of this study was estimate base (Tb) water potential (?b) for germination Chenopodium album, Amaranthus retroflexus, Setaria pumila, Panicum...

Weed behaviour in crop fields has been extensively studied; nevertheless, limited knowledge is available for particular cropping systems, such as no-till systems. Improving weed management under conditions requires an understanding of the interaction between residues and seedling emergence process. This study aimed to evaluate influence maize wheat residues, applied three different quantities (...
