| 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: Continuous and excessive use of herbicides to control various weed biotypes is posing severe threats to soil and human health. Nevertheless, the strategy of using allelopathic crop residues and water extracts for weed control seems to be a sustainable and friendly option to reduce dependence on synthetic herbicides. In addition to controlling weeds, residues of allelopathic crops positively affected soil health. A two-year field study was carried out to examine the impact of sunflower residues on soil properties, weed dynamics and productivity of mung bean. The study was comprised of five treatments viz., control, sunflower water extracts at 10 and 20 L ha-1, and sunflower residues incorporation at 4 and 6 ton ha-1. Results indicated that... |

| ABSTRACT: A field trial was conducted with the aim of assessing weed seed bank status of soil under maize cultivation. It was worked out by sampling from soil corer at different depths ranging from 0-5, 5-10, 10-15, 15-20 and 20-25 cm. Weed seed bank was monitored with a cultivator, a rotavator, a mouldboard plough (MB) and a chisel plough in tilled plots under Atrazine 330 EC at 1.00 kg a.i. ha-1 at 20 DAS, hand weeding at 20 and 40 DAS and no weeding. Sixteen weed species were identified in soil samples, four species contributing about 72% of the total weed seed bank. Tillage system was more important determinant of weed seed density than the weed management practices. Movement pattern of weed seeds by all tillage treatments differ significantly over... |
