A field experiment with the objectives to understand evaluation of mulching effects on weed control in blackgram production under irrigated condition involving two factors viz., (paddy straw mulching, sugarcane trash no mulching) and herbicidal treatments (pendimethalin pre-emergence (PE) @ 1.0 Kg/ha, pendimathalin + Imazethapyr (pre-mix) Valor 32% EC Hand weeding 15 30 days after sowing, weedy...

The field experiment was carried out during the summer season of 2021-2022 to study response different weed management practices on growth and yield black gram. Cyperus sp., Phyllanthus niruri, Trianthema portulacastrum, Amaranthus viridis were dominant weeds. It observed that besides free treatment lowest count, dry weight weeds (3.66 g m-2), index (2.73%) as well highest control efficiency (6...

Sweetpotatoes, Ipomoea batatas (L.) Lam. (Convolvulaceae), are typically grown on bare soil where weeds and erosion can be serious problems. Conservation tillage systems using cover crop residues as mulch can help reduce these problems, but little is known about how conservation tillage affects yield and quality of sweetpotato or how these systems impact populations of beneficial and pest insec...

a field experiment was conducted in khorramabad to evaluate the efficacy of 12 herbicides [ethalfloralin (3 l.ha-1), trifloralin (2 l.ha-1), pendimethalin (1.5-2.5 l.ha-1), imazethapyr (0.5-0.7 l.ha-1), isoxaflotole (80 g.ha-1), pyridate (2.5 l.ha-1), bentazon (2 l.ha-1), metribuzine (0.7 kg.ha -1), fomesafen (1 l.ha-1), simazine (80 g.ha-1), prometrine (830 g.ha-1), haloxyfop-r-methyl (1 l.ha-...

Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technolo...

Approaches that involve manipulating T cells outside the body and then replacing them have shown promise. However, researchers worry that such cells could provoke autoimmunity because they don’t pass through negative selection, the weeding-out of self-targeted T cells in the thymus. Other concerns are that the re-introduced T cells won’t survive very long and that they won’t generate the memory...

Weeds constitute a serious problem to wheat crops and cause great loss the yield. Manual weeding is labor-intensive time-consuming. Chemical weed control has negative impact on both environment humans. Today agricultural sector requires non-chemical that safeguards consumers demand for high quality food products pay special attention safety. The objectives of study was evaluate performance an-e...
