Marketable tuber yield stability in potato
Cereal research communications, 2008In the paper was analyzed marketable tuber yield stability of eight foreign potato cultivars (Arosa, Rosara, Velox, Flavia, Satina, Hopehely, Goliath and Rioja) grown in Croatian production environments for three growing seasons (2003-2005), on four locations (Brinje, Varaždin, Velika Kopanica and Osijek).

Effects of breaking seed tubers on yield components of the tuber crop Plectranthus edulis
The Journal of Agricultural Science, 2012SUMMARYPlectranthus edulis is an ancient tuber crop, cultivated in Ethiopia, which produces stem tubers on stolons below the ground; however, agronomic and physiological information on this crop is scarce. Three field experiments were carried out at each of two locations (Awassa and Wondogenet, Ethiopia).

Decreasing NPK dose less than the recommended dose decreased significantly tuber yield [measured as tubers yield (g) per plant, tubers numbers per plant, tubers dry weight per plant and total yield (ton/fed.) as well as its components from protein, ascorbic acid ,starch, N, P ,K, total soluble solids and specific gravity in both studied seasons.

Effect on Tuber Yield of the Exposure of Yam Tubers to Light1
Agronomy Journal, 1976AbstractThis study was designed to determine the effect of exposure of yam (Dioscorea alata L.) tubers to light on tuber yield, since the emergence of yam tubers from the ground as a result of a compacted or restricting soil layer was found by the authors in previous unpublished studies to be associated with reduced tuber yield. Yam tubers were allowed

Potato Growing, 2020
The research results of the effect of top dressing on the potatoes plants yield in the first tuber generation in the protected ground are presented in the article. It was found that for the early and middle ripeness groups, two-fold treatment with the preparation Nanoplant Co, Mn, Cu, Fe during the vegetation period gave a significant increase in the ...

THE EFFECT OF FLOWER REMOVAL ON POTATO TUBER YIELD
Canadian Journal of Plant Science, 1990Relationships between fruit and vegetative growth may influence tuber yield. In 1987, flower removal significantly increased yield at irrigated and dryland sites for the potato clone ND860-2. In 1988, flower removal did not significantly increase yield in Norchip, ND2008-2 or ND860-2 planted under dryland conditions. Response to flower removal appears

The physiology of growth and tuber yield
1978In the past decade there have been several books and reviews which have considered the physiology of potatoes (Ivins and Milthorpe, 1963; Burton, 1966; Milthorpe and Moorby, 1967; Moorby and Milthorpe, 1975). The first two of these were concerned, in part, with trying to put the study of the potato crop on a firm fundamental basis.

The Journal of Agricultural Science, 1979
SUMMARYSix experiments are reported which examined the effects of various seed cutting treatments on numbers of tubers and tuber yields of several maincrop potato varieties. Using conventional potato ridges, the cutting of seed tubers into 12 mm cubes or the use of potato peel reduced early growth and yields compared with whole tubers in some ...

EVALUATION OF AN OPTICAL SENSOR FOR TUBER YIELD MONITORING
Transactions of the ASAE, 2004A sensor for monitoring the yield of tubers was tested in the laboratory and in the field. The laboratory test was designed to investigate whether the sensor varied in its measurements of tuber size, whether the recorded size differed within the width of the sensor, and whether tilting of the sensor affected the result. The test objects were spheres,
