Isabgol (Plantago ovata Forsk) seed germination and emergence as affected by environmental factors and planting depth
Isabgol (Plantago ovata Forsk) seed germination and emergence in response todrought (Polyethylene glycol 8000) and salinity stress (NaCl), temperature, pH andplanting depth were studied in laboratory and greenhouse experiments. Base,optimum and ceiling germination temperature were estimated as 3.35, 21.24 and35.04 oC, respectively. Isabgol seed is rather tolerant to low water potential and high...
متن کاملImpact of soil type, moisture, and depth on swede midge (Diptera: Cecidomyiidae) pupation and emergence.
Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), a common insect pest in Europe and a new invasive pest in North America, causes severe damage to cruciferous crops. Currently, many counties in Canada and the United States in which C. nasturtii has not been previously reported are at risk of being infested by C. nasturtii. Effectiveness of chemical control is limited, especially under hi...
متن کاملEstimation of Soil Erosion Time Paths : The Value of Soil Moisture and Topsoil Depth Information
Rates of soil erosion in the dryland cropping region of Saskatchewan are investigated under alternative cropping strategies. Chemical fallow is examined as an alternative to tillage fallow for moisture and soil conservation. Conclusions include: (a) flexible cropping increases net discounted returns and substantially reduces soil erosion compared to the predominant crop rotation; (b) chemical f...
متن کاملStudy of Changes in Soil Moisture and Salinity Under PlasticMulch and Drip Irrigation in Pistachio Trees
In this study, changes in soil moisture and salinity contents in drip irrigation combined with white and black plastic mulches compared to no mulch (control) was evaluated. The experiment was carried out in two commercial pistachio orchards (Ohadi cultivar) with irrigation frequencies of 8 to 12 days with a total water consumption 4100 and 6170 m3ha−1. The study was conducted in a complete rand...
