| ABSTRACT: Phytotoxic effects of allelopathic crop residues are important to trickle for their use as a source of organic amendments to improve soil fertility. In present study, through pots and two year field studies, we examined the integrated effect of allelopathic residues and NPK fertilizer treatments including T0 (control), T1 (200-150-100 kg NPK ha 1), T2 (100-75-50 kg NPK ha-1 + mung bean straw 4 t ha-1), T3 (100-75-50 kg NPK ha-1 + rice straw 4 t ha-1), T4 (mung bean straw 8 t ha-1) and T5 (rice straw 8 t ha-1) under different water regimes on soil fertility and wheat crop. Solo application of mung bean residue and rice straw caused significant inhibition of various germination and growth traits of wheat while minimal inhibition occurred when... |

| ABSTRACT The application of sewage sludge (SS) in agriculture is a practice used worldwide, and it is commonly applied in sugarcane to supply nutrients, with beneficial effects on crop productivity and soil; but SS can increase sorption and decrease desorption of herbicides. However, in tropical soils such as in Brazil, there are no studies regarding the behavior of pre-emergent herbicides, mainly aminocyclopyrachlor and mesotrione, in SS-amended soil. The aim of the present study was to determine the effect of municipal SS applied in agriculture on the sorption–desorption of aminocyclopyrachlor and mesotrione in clay soil. Aminocyclopyrachlor (pyrimidine-2-14C-aminocyclopyrachlor) and mesotrione (cyclohexane-2-14C-mesotrione) sorption–desorption was... |
