Book The Effects of Nitrogen  Potassium and Chloride on Nutrient Composition in Russet Burbank Potatoes  Solanum Tuberosum

Download or read book The Effects of Nitrogen Potassium and Chloride on Nutrient Composition in Russet Burbank Potatoes Solanum Tuberosum written by Ishwar Prasad Murarka and published by . This book was released on 1971 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three greenhouse experiments were designed to measure the effects of N, K and Cl on the nutrient uptake by Russet Burbank potatoes (Solanum tuberosum). A Deschutes sandy loam soil from Powell Butte area in Central Oregon, low in potassium, was used to study these effects. Nitrogen applications produced significant increases in dry matter yield when applied in combination with at least 100 ppm of K. It was noted that the most significant changes in nutrient composition in the plant tissues occurred when 100 ppm N was added together with at least 100 ppm of K. Yield depressions were encountered when 600 or 800 ppm N was applied. Chloride application changed the nutrient composition without causing any significant effect on total plant growth. Nitrogen application significantly increased all nitrogen components and uptake of Ca and Mg. Greatest increases occurred with the 100 ppm N rate. Nitrogen application caused significant reduction in Cl content and uptake. Potassium content was reduced by applied N, but K uptake was reduced only when excessive N applications reduced yields. Potassium application significantly increased K content and uptake at all levels of N. Significant decreases in Mg content and uptake were obtained whenever X was applied. Small decreases in Ca content were also noted when K was applied. Potassium application reduced the contents of certain nitrogen fractions in the plants; but the total uptake of N was generally increased when K was added. Nitrogen and K applications changed the milliequivalent sums of cations (C = Ca+Mg+K+Na), anions (A = NO3+P+S+CI), and total anions (TA = N+P+S+CI). Nitrogen addition increased all three sums, whereas K application decreased the three sums. There was no significant change in cation minus anion, (C-A), content as a result of K fertilization, indicating that a constant organic acid production was maintained independent of K level. However, N application reduced the (C-A) content, indicating a compensatory reduction in the organic acid contents when the anion uptake was not matched by an equal amount of cation uptake. It was generally found that there was a higher accumulation of inorganic ions in the stems than in the leaves. Specifically, more NO3-N was found in the stems whereas more protein-N was found in the leaves. The total anions, (TA), however, were comparable for both plant parts. A very important finding was that the application of Cl reduced the level of NO3-N and total N found in the plants but did not change the amount of N found in the protein fraction. Almost all of the decreases in content and total uptake of N were presumably due to the antagonism in the accumulation of NO3 and CI ions in the plants. It appears that the uptake data provided a better index for evaluating the responses and effects of the applied nutrients than did the content data.

Book Potato Yield and Grade as Influenced by Nitrogen Fertilizer and Irrigation Frequency

Download or read book Potato Yield and Grade as Influenced by Nitrogen Fertilizer and Irrigation Frequency written by Clinton Cecil Jacks and published by . 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.
