“…The faster the crop canopy develops and soil is covered, the more radiation is absorbed by the crop and the higher the yield. On the other hand, oversupply of nitrogen during early growth stages causes excessive growth of the foliage, resulting in too large a canopy for optimal yield development (Krauss 1978, Kuisma 1995. Nitrogen itself has little effect on the amount of dry matter produced per unit of intercepted solar radiation (Millard and Marshall 1986).…”

The effects of nitrogen fertilization on the yield and quality of early potato (Solanum tuberosum L.) were studied at MTT Agrifood Research Finland during 1996-1997. Cultivars were harvested at three times. The experimental layout was a split-split-plot with harvest times as main plots and nitrogen fertilization and potato cultivars as the subplots. The fertilizer treatments were 60 and 120 kg N ha -1 and the cultivars tested were Timo, Gloria and Van Gogh. The harvest times were 57-62, 70-75 and 85-90 days after planting. Application of 120 kg N ha -1 intensifi ed canopy development and increased leaf area of the stands. At early harvest the tuber yield of all cultivars receiving the higher nitrogen application increased by 0.5-2.5 t ha -1 . The highest yielding cultivar was Timo. At last harvest, the higher nitrogen treatment increased yield by 3.0-6.2 t ha -1 . The highest yielding cultivars were Timo and Van Gogh. The dry matter content of tubers was very low, 13.8-17.2%, at the fi rst harvest and the higher nitrogen application reduced dry matter content by 0.3-1.0%. The highest fertilizer application rate resulted in the largest tuber size. Nitrogen application, however, affected the quality of potatoes by decreasing the dry matter content. The nitrate content in tubers increased signifi cantly with the increasing level of nitrogen. The range of nitrate content in tubers fl uctuated between 13 and 189 mg kg -1 fresh weight showing good controlling of nitrate values. Harvest time affected sucrose content and the reducing sugar content in tubers, but nitrogen fertilizer did not change the sugar content of tubers. As tuber yield and quality during a short growing season are affected mainly by intercepted radiation, methods to increase tuber yield should focus on reducing the time to emergence, improving haulm growth after emergence and increasing the harvest index.

“…Short days stimulate the process, while long days prevent or retard it. The response to photoperiod interacts with many other factors, such as genotype (Ewing, 1981(Ewing, , 1985, nitrogen level (Krauss ,1978) and the age of mother tubers (Montaldi and Claver, 1963). As to the genotype, late-maturing cultivars have a shorter critical photoperiod for tuberization than the earlymaturing cultivars (Ewing, 1981).…”

“…12 ) This function could lead jasmonic acid (2) being a trigger compound for the tuberization of Jerusalem artichoke and potato, because at the first stage of tuber formation, the radial expansion of pith c:ells at the stolon tip occurs and is followed by cell division. 13 ) Although the biosynthesis of tuberonic acid (6) is presently unknown, it is presumed that tuberonic acid (6) arises from the oxidation of jasmonic acid (2). Since methyl 5'-O-p-o-glucopyranosyl tuberonate (3) was also isolated from Jerusalem artichoke as a tuber-forming substance, it seems reasonable to assume that tuberonic acid (6) plays an important role in the tuberization of relevant plants.…”
