Potatoes irrigation

The first step toward attaining these goals was to collect aldicarb residue concentrations and other water quality parameters for water samples withdrawn from various depths in the aquifer in and around several fields in which irrigated potatoes had been... [Pg.222]

There are a number of cultural and environmental conditions which prevail during the growing season and strongly affect the processing quality of potatoes climate, rainfall, irrigation and soil moisture, soil type, time of planting and harvesting, kind and amount of fertilizers used, and control of insects and diseases. [Pg.169]

Many factors affect the mineral composition of potatoes, for example location, stage of development, soil type, soil pH, soil organic matter, fertilization, irrigation, and weather. Genotypic... [Pg.408]

Potassium, phosphoms, calcium, and magnesium concentrations changed with irrigation and fertilization in physiologically mature tubers (Ilin et al., 2002). The total concentration of iron, calcium, and zinc increased with application of fertilizers whereas the content of phosphoms and molybdenum was reduced (Bibak et al., 1999 Frossard et al., 2000). The wide range of mineral content reported in potatoes may not only be due to genotype and environmental factors, but also sampling issues. [Pg.409]

The parasites which cause plant diseases may be spread by wind, rain, insects, birds, snails, slugs, and earthworms, transplant soil, nursery grafts, vegetative propagation (especially in strawberries, potatoes, and many flowers and ornamentals), contaminated equipment and tools, infected seed stock, pollen, dust storms, irrigation water, and people. Figure 3.8 illustrates the effects of microbial infection of various fruit trees. [Pg.86]

Site Selection. Nine 160-acre (65-ha) irrigated fields in two of the main potato-growing counties of Wisconsin (Portage and Waushara, 6.4 and 2.2 million cwt. or 3.2 and 1.1 million quintals in 1981) were selected for study. Soils in each field were well drained sands or loamy sands, mainly of the Plainfield series... [Pg.222]

Monitoring wells were also placed in four test plots sown to potatoes at the University of Wisconsin-Madison Experimental Farm, near Hancock, Wisconsin. These plots were treated with aldicarb at a rate of 2 lb. a.i./A (2.24 kg/ha) at planting and at plant emergence. One set of plots was irrigated at a rate corresponding to the measured evapotranspiration rate for the region, the second set at 1.6 times the evapotranspiration rate (21). [Pg.224]

As a result, 3-5 times as much aldicarb leached below two meters with irrigation. Applications at potato emergence decreased the amount to leach by about one-half as compared to earlier applications at planting. The reasons for this are two-fold avoidance of some spring rain for later applications, and a more rapid rate of decay for later applications. [Pg.364]

There are other preconditioning techniques in addition to heat that could lead to chilling tolerance. Irrigation with saline water (0.25% NaCl w/v) improves carotenoid content and antioxidant activity of tomato (De Pascale et al. 2001) and may lead to enhanced chilling tolerance. In sweet potato cultivars, enhanced coloration as a result of soil condition and water availability also led to high antioxidant potential (Philpott et al. 2003). [Pg.75]

Highlight. The transfer factors of uranium from the soil to the plant show a strong dependence on the type of soil, uranium content in the soil, the type of plant and irrigation (for a comprehensive list, see Environment 2007). In addition, as mentioned earlier, the distribution of uranium within the plant parts has a tendency to concentrate in the roots, and in the peels of tubers but not inside the peeled potatoes. [Pg.147]

Irrigation ean often encourage disease development by altering the crop environment so that it is more conducive for disease spread and survival one exception is in potatoes where irrigation applied as the tubers are initiated can be very effective at controlhng common scab. [Pg.128]
