This book was released on 2002 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the context of improving water productivity, there is a growing interest in deficit irrigation, an irrigation practice whereby water supply is reduced below maximum levels and mild stress is allowed with minimal effects on yield. Under conditions of scarce water supply and drought, deficit irrigation can lead to greater economic gains than maximizing yields per unit of water for a given crop; farmers are more inclined to use water more efficiently, and more water-efficient cash crop selection helps optimize returns. However, this approach requires precise knowledge of crop response to water as drought tolerance varies considerably by species, cultivar and stage of growth. The studies present the latest research concepts and involve various practices for deficit irrigation. Both annual and perennial crops were exposed to different levels of water stress, either during a particular growth phase, throughout the whole growing season or in a combination of growth stages. The overall finding, based on the synthesis of the different contributions, is that deficit or regulated-deficit irrigation can be beneficial where appropriately applied. Substantial savings of water can be achieved with little impact on the quality and quantity of the harvested yield. However, to be successful, an intimate knowledge of crop behavior is required, as crop response to water stress varies considerably.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Southern Manitoba, potato producers are experiencing wetter and drier conditions within the soil profile during the growing season leading to poor quality and inconsistent yields. Russet Burbank Potato cultivar was grown in Southern Manitoba on fine sandy loam soil in a two year (2013-2014) study using two water management treatments: (i) overhead irrigation and (ii) no-irrigation. The main objectives of the study were (i) to assess the impact of overhead irrigation on water table depth and potato yield (ii) to estimate the shallow groundwater contribution to potato water requirement through upward flux (iii) to track the nitrogen dynamics within the potato root-zone under overhead irrigation and no-irrigation scenarios (iv) to examine the effects of no-irrigation and overhead irrigation system at critical growth stages on marketable yield and quality of potatoes. In 2013, water was applied using a linear move irrigation system and in 2014 a rain gun irrigation system was used for the irrigated treatment. Volumetric soil water content, precipitation, irrigation depth, water table depth, nitrate concentration and electrical conductivity in potato root-zone, groundwater electrical conductivity, weather variables, total potato yield, marketable yield, and quality parameters were measured. The total yield was not significantly different between the two treatments in both years. The marketable yield of the irrigated treatment (36.89 MT/ha) was 20% higher (p = 0.017) compared to the non-irrigated treatment (30.74 MT/ha) in 2013. However, no significant difference was found between the irrigated (39.0 MT/ha) and non-irrigated (43.7 MT/ha) treatments in 2014. Potato yields from both treatments were significantly correlated with the average groundwater depth. Water balance analysis within the root-zone during rainy and rain-free periods showed that nitrate rich groundwater may have contributed to some of the crop water demand. The lack of rainfall and high temperature during tuber initiation and tuber bulking stages resulted in the accumulation of high concentration of nitrates within the root-zone by the late release of nitrates from the polymer-coated urea and the upward migration of groundwater containing 55 ppm and 70 ppm of nitrates in the 2013 and 2014 growing seasons, respectively. Overhead irrigation was found to be economically advantageous to produce better quality potatoes with higher marketable yields.

This book was released on 1972 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of irrigation frequencies and rates and time of nitrogen fertilizer application on the yields, grades and N status of Russet Burbank potatoes were determined on a sandy soil near Hermiston, Oregon. Increasing the frequency of irrigation from 72 to 48 to 12-hours did not result in increases of yields or improved grades of tubers during the growing season. Optimum yields and grades were obtained when 196 lbs. N/A was applied in a single fertilizer application with 88 lbs. N/A in the soil as nitrate-N. This N treatment corresponded to 0.58, 0.42, 0.46, 0.32 and 0.17 percent petiole nitrate-N on July 6, July 21, August 4, August 24 and September 9 sampling dates, respectively. Split N fertilizer applications resulted in higher petiole nitrate-N levels during the growing season, similar total yields and lower yields of U.S. No. 1 tubers than treatments in which all of the fertilizer was applied at planting. The higher petiole nitrate-N levels delayed tuber maturity and subsequently the split N applications were influenced by the high soil and air temperatures in July and August and formed increased yields of off-shape tubers. This emphasizes the importance of adequate N early in the growing season in order to prevent delayed vine and tuber growth and the importance of even assimilation of nutrients by the tubers in later stages of development.
