Tillage and Weed Management Effect on Weeds, Non Target Toxicity in Soil and Yield of Soybean
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 9
Abstract
In a field experiment conducted during rainy season 2010 and 2011, at Indian, Agricultural Research Institute, New Delhi, the effect of tillage and weed control measures was investigated on weeds, soil non-target toxicity and soybean growth and yield. The experiment was laid out in split plot design with three replications. The treatments comprised of conventional tillage (CT) and no-tillage (NT) as main plots, and 8 levels of weed control measures as sub-plots. Yearly as well as pooled density of grass, broadleaved and sedge weed density, and dry weight of broad-leaved and sedge was mostly significantly lower in no-tillage compared to conventional tillage, but reverse was true for grass dry weight. Soybean yield was not affected by tillage treatments, but all weed control treatments gave significantly higher soybean seed yield compared to weedy check. Pendimethalin 0.5 kg/ha + imazethapyr 0.075 kg/ha were comparable and weed-free check was superior to all other weed control treatments in this regard. Populations of fungi, bacteria and actinomycetes, and soil dehydrogenase activity (DH) and microbial biomass carbon (MBC) were significantly higher in no-tillage treatment in both years. Weedy check and weed-free check were comparable to each other, followed by pendimethalin 0.5 kg/ha + imazethapyr 0.075 kg/ha and pendimethalin 0.75kg/ha alone showed the highest value of these parameters.
