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.

This book was released on 2012-07 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato production is an important agricultural activity in the southern Ethiopia. However, the yield of the crop is very low due to a number of constraints among which low soil fertility and poor agronomic practices are few. Therefore, the experiment was conducted to evaluate the effect of nitrogen fertilizer and plant spacing on growth, yield and yield components of potato (Solanum tuberosum L.) at Umbullo Watcho watershed, Southern Region in 2010 cropping season. The experimental treatments; five nitrogen levels (0, 55, 110, 165 and 220 kg N ha-1) as sub plot and three intra- row plant spacing (25, 30 and 35cm) as main plot were laid out in split plot design with three replications. Therefore, the research was carried out with the following objectives: Evaluate the effect of nitrogen fertilizer and /or plant spacing on growth and tuber yield of potato, assess nitrogen fertilizer use efficiency and nutrient recovery by the potato crop and assess the economic benefit of nitrogen fertilizer use.

This book was released on 2013 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted at eastern zone of Tigray, Ethiopia during 2012 rainy season to evaluate the effect of phosphorous and potassium fertilizer rates on the yield and yield components of potato (Solanum tuberosum L.). In this experiment a combination of four levels of phosphorous and four levels of potassium were used. The design used was a factorial experiment arranged in Randomized Complete Block with three replications in two locations. The recommended N 110 Kg/ha rate for potato was applied as urea to all treatments equally. The study revealed that effect of location and PK fertilizer rates had helped to significantly increase the growth parameters, yield components, marketable yield, total tuber yield and nutrient use efficiency of potato. Moreover, days to flowering and physiological maturity, number of stems per hill, unmarketable yield and fertilizer use efficiency were significantly affected by the interaction of PK fertilizer and location. The optimum total tuber yield was obtained due the effect of PK fertilizer. The highest total and marketable tuber yield increase by 36.9 and 45 %, respectively compared to the control was obtained due to PK application.

Book excerpt: The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.
