Dissipation of fenpropathrin residues in squash fruits intercropped with garden rocket

The dissipation and residue of fenpropathrin in squash fruits intercropped with garden rocket under field conditions were studied. Samples were collected periodically on the sampling days after applications. The residue data revealed the half-life values of fenpropathrin in Squash fruit and garden rocket were found to be 1.78 and 1.85 days, respectively. The residues of fenpropathrin were more greatly concentrated in...

Quantitative and qualitative analyses of weed seed banks of different agroecosystems

One of the main survival mechanisms of weeds in constantly disturbed environments, specially the annual weeds, is their high production of seeds. In this study it was intended to evaluate the influence of different agroecosystems (vegetable garden, pasture, native field, soybean, dry bean and corn) on the strength of the seed bank, making quantitative and qualitative analyses. On each site, soil samples were collected,...

Effect of transpiration suppressants and nutrients under rainfed conditions: An integral view on crop productivity and biological indices in millet/pulses intercropping system

Under rainfed condition (650 mm/annum) of India drought of unpredictable intensity and duration is a prevailing feature. Appropriate intercropping combinations and management practices for sustaining crop productivity in such situations needs to be worked out, where monoculture is prevailing. Objectives were to examine the effect of transpiration suppressants and nutrients on sustaining productivity, profitability of...

M-mode echocardiographic study in dogs

Echocardiography is a unique non-invasive application of ultrasound for imaging of living heart. It is based on detection of echoes produced by a beam of ultrasound pulses transmitted into the heart. Conventional echocardiographic modalities include two-dimensional (2D), M-mode and Doppler modes. M-mode is the first ultrasound modality used in which the ultrasound beams are aimed manually at selected cardiac structures...

Biomass yields and crude protein content of two African indigenous leafy vegetables in response to kraal manure application and leaf cutting management

African indigenous leafy vegetables have the important role of providing essential minerals, vitamins and amino acids in diets of poor smallholder farmer households in sub-Saharan Africa. A study was conducted to quantify the influence of applying cattle and goat manure on the biomass yields and crude protein content of two commonly used African leafy vegetables (Cleome gynandra and Amaranthus hybridus) when subjected...

Relative performance of oat (Avena sativa L.) varieties for their growth and seed yield

Deficit of the feed and fodder availability of the desired quality has been considered as the major bottleneck in harnessing the potential of the livestock sector in India. With the objective to find out the suitable variety of oat for getting maximum seed yield, a field experiment was conducted during rabi season of 2007 to 2008 at JNKVV, Jabalpur (MP). The treatments consisted of six varieties of oat (Kent, UPO...
