The Impact

Gaining high yield of potato is very crucial for farmer and quality also has a great impact on their production. Beside the quality and yield using the amount of irrigation also important to reduce water lose. The tuber yield and quality of potato (Solanum tuberosum L.) is impacted by irrigated water. This study was carried out in two respectively season (2017 and 2018) in Halabja province of Kurdistan regional of Iraq to evaluate the impact of irrigation interval on quality and tuber yield in potato cultivars. In this study there are  four irrigation intervals (3,5,7 and 9 days) used by furrow irrigation method which subjected in complete randomized design (CRD) with three replications. The potato tuber production in 3 day interval showed highest percentage also protein and starch content was recorded highest in both year of cultivation, but the abscisic acid was affected by more irrigation which in 3 day interval irrigation the rate was less than other. Also in 5 day interval irrigation the rate was acceptable because there is no significant difference in terms of tuber yield, protein and starch content if compare with 3 day interval irrigation in particular for those area faced restricted in using water irrigation.

Yield And Quality

A field experiment was conducted in Eastern Tigray, Ethiopia, during the summer season to determine the effects of flower removal and earthing up time on the tuber yield and quality of potato (Solanum tuberosum L.). The experiment comprised three flower removal stages and five earthing up time treatments, which were laid out in a randomized complete block design (RCBD) of a 5x3 factorial arrangement with three replications. Data collected on tuber yield and quality parameters were analyzed using SAS version 9.2. The interaction of flower removal stages and earthing up time treatments affected marketable and unmarketable tuber number and yield, total tuber number and yield, large-sized tuber weight, and number of large-sized tubers. The medium and small-sized tubers were also affected by main treatments but not by their interaction treatments. Similarly, dry matter content was significantly (p<0.05) affected by flower removal alone, but not by earthing up time and its interaction with flower removal. Generally, the highest marketable tuber yield (30.25 t ha-1), large-sized tuber weight (424.9 g), the number of large-sized tubers (5), and total tuber yield (30.96 t ha-1) were recorded in the treatment of potato flower removed at the bud stage and earthed up at 15 days after complete emergence. Therefore, the removal of potato flowers at the bud stage and earthing up at 15 days after complete emergence and common cultivation can be practiced for better tuber yield and quality of potato.

Abstract Studies on effect of organic, inorganic and bio-fertilizers on yield and quality attributes of potato (Solanum tuberosum L.) variety Kufri Jyoti, comprising of 10 different treatments using randomized complete block design with three replications were conducted at Post Graduate Centre, University of Horticultural Sciences, Campus, Gandhi Krishi Vignana Kendra, Bangalore during Rabi 2011. Application of 50% RDF + 50% FYM + Azotobacter + Phosphobacteria (T7) showed significantly maximum number of tubers per plant (7.87), tuber yield per plant (363.33 g plant− 1) and tuber yield per hectare (34.13 t ha− 1). This treatment also produced maximum tuber dry matter (21.67%), starch content (78.20%) non-reducing sugars (0.84%) and total sugars (1.74%) which were on par with T3, T4 and T6 during rabi 2011.

The yield and quality of potato in South Korea vary with different environmental conditions and all induced varieties do not perform well in every location. There are many suggested reasons for this problem; they include soil topography, temperature, rainfall pattern, etc. This study focused on finding certain potato genotypes based on high yield and quality (marketable rate, uniformity, less physiological disorders, resistance to diseases), and suitability for processing in three agro-ecological regions in South Korea. Thirty-two potato genotypes were cultivated in three regions i.e., Chuncheon (low altitude), Yang-gu (middle altitude), and Pyeong-chang (alpine), along with three major cultivars (Atlantic, Shepody, and Superior) as control. All the potato lines were evaluated for three consecutive years. The results showed that a higher tuber yield was obtained from the genotypes Gangwon Valley, Valley 11, Valley 13, and Valley 92 in Chuncheon; while Valley 13, Valley 43, and Valley 92 in Yang-gu; and Valley 43, Gui Valley and Valley 92 in Pyeong-chang region with a high marketable quality, and lower infection rates and physiological disorders. The results also showed that higher chip lightness was manifested by the genotypes Juice Valley, Gangwon Valley, Rose Valley, Valley 43, and Valley 91 among the high yielding genotypes. Besides, Pyeong-chang (alpine), a high-altitude region with longer maturation time was found more suitable for potato cultivation, especially for higher tuber yield and higher quality products for potato chip processing.

Selection For

Seven quantitative traits of the cultivated potato (Solanum tuberosum L.) were studied in a partial diallel cross experiment. Large specific combining ability effects were observed for total and marketable yields, total number of tubers, and number of marketable tubers. Large general combining ability effects were obtained for average weight per tuber, average weight per marketable tuber, and specific gravity. The SCA effect for specific gravity was also significant. It is suggested that the difference of combining ability performance noted above for the two yield components was due to a long history of directional selection for high yield and stabilizing selection for tubers within the marketable size range. There were low frequencies of both GCA and SCA effects showing significant difference from the population mean. This is interpreted as an affirmation of the narrow genetic base which exists in the present gene pool in Solanum tuberosum. Heritability estimates based on GCA effects indicated that parents can be efficiently selected for average tuber weight and specific gravity.
