An experiment was conducted to study the effect of harvesting dates and variety on the yield and processing quality of potato tuber. Three processing potato varieties (BARI Alu-25, Asterix; BARI Alu-28, Lady Rosetta and BARI Alu-29, Courage) were used as test crops and they were harvested at different days after planting [80, 90, and 100 days after planting (DAP)]. The three processing potato varieties showed higher tuber yield of Grade A (9.12 t ha-1) and B (13.64 t ha-1). The highest tuber yield (Grade A+B) [29.62 t ha-1] and total tuber yield (35.97 t ha-1) was found in Courage at 90 and 100 DAP harvest, respectively. The variety Lady Rosetta attained the highest percent of processable tuber yield (86.8% of the total tuber yield), the maximum dry matter content (26.37%), specific gravity (1.102) at 90 DAP harvest and this variety also contained the highest mean starch content (111.75 mg g-1 FW) followed by Courage (111.17 mg g-1 FW) and Asterix (103.95 mg g-1 FW). Optimum dry matter content (24.07%), specific gravity (1.091), starch content (110.15 mg g-1 FW), processable tuber yield (26.62 t ha-1) and total tuber yield (32.76 t ha-1) was found at 90 DAP harvest and therefore, it could be mentioned as suitable harvesting date for processing purposes. Among the varieties, Lady Rosetta and Courage were found preferable potato varieties that could be used for processing of potato products. Bangladesh J. Agril. Res. 44(1): 179-193, March 2019

A total of 37 different poplar varieties were grown in a randomized mini-rotation short rotation coppice (SRC) (harvest every three years) on a light sandy soil under continental climatic conditions in the south of the Federal State of Brandenburg, Germany. Along with well-known poplar varieties, newly bred ones that have not yet been approved for commercial use were selected for this study. Survival rates were determined after the first growing season in 2013 as well as at the first and second harvests in 2015 and 2018. Furthermore, the number of shoots, plant height, diameter at breast height, dry matter content and biomass yield of the varieties were recorded. After the second rotation period, only seven poplar varieties yielded more than 11 tadm ha−1 y−1 and can be recommended for commercial use. However, many varieties only reached about 8 tadm ha−1 y−1, and six varieties even had less than 4 tadm ha−1 y−1, among them newly bred varieties. Given the changing climate conditions, the cultivation of these varieties in SRC is not recommended. Our data also show that the biomass yield of several varieties decreased from the first to the second harvests. Since the survival rates were high and no damage by pest species was observed, the site-specific yield capacities of the individual clones are assumed to be the cause for this.

French fries and potato crisps are the most consumed industrially processed potato products in Kenya, especially in the major urban centers. Processors have, however, complained of the inadequate supply and low quality of potatoes currently available in the market. This study was instituted to evaluate the suitability of three newly released Kenyan potato varieties for processing . The three new potato varieties (Purple Gold, Kenya Mpya and Sherekea) and two established varieties (Tigoni and Dutch Robjin) used in this study were grown under standard conditions at the National Potato Research Centre, Kenya . They were harvested at maturity, cured and analyzed for physico -chemical characteristics and processed into crisps and French fries for suitability evaluation. All the cultivars had tuber sizes within recommended range for crisps (40 -60 mm) and French fries ( ≤ 45 mm). Dry matter contents differed significantly (P ≤ 0.05) among the varieties ranging from 20.81 % in Golden Purple to 25.77 % in Kenya Mpya . Crisps oil content varied significantly (P ≤ 0.05) from 31.28 % in Kenya Mpya to 36.8 % in Golden Purple while it ranged from 7.51 % to 8.81 % in French fries of the same varieties. Dry matter content was negatively correlated to oil contents of crisps and French fries. Significant (P ≤ 0.05) varietal differences in color and textural properties of crisps and French fries were noted. Kenya Mpya, Tigoni, Sherekea and Golden Purple in that order of preference could be used to produce crisps that are comparable to Dutch Robjin, an established crisping variety in the local market. With the exception of Kenya Mpya, varieties Sherekea, Dutch Robj in and Golden Purple produced good quality French fries comparable to the established chipping variety , Tigoni. Potatoes from the new varieties are expected to form an additional pool of raw material for processing in Kenya and should be promoted alongside the established ones to support the growing industry.

In Hungary, the growing area of potato area reduced dramatically in the last few decades, additionally we are lagging behind the Western European countries as regards yields and the competitiveness of production is further decreased by the great alternation in yields from year to year, the unpredictable market conditions, bad consumption habits and many times unfortunately the lack of quality products.The ecological and climatic conditions of Hungary are not everywhere suitable for potato, in the area of Debrecen the amount of rainfall was lower, and the monthly average temperature was higher than the requirement of potato in its growing season in 2002 and 2003.The experiment was carried out at the experimental site of the University of Debrecen, Farm and Regional Research Institute, at Látókép. In our experiment we examined the yield and some quality parameters of 8 and 9 medium-early varieties in large parcels in 2002 and 2003 respectively. Out of the examined varieties 3 are of Dutch, and 6 are of Hungarian breeding.The experiment was set up on 49.5 m2 parcels on calcareous chernozem soil after winter wheat as a forecrop in both years. The 9 varieties were examined in 4 repetitions in randomized blocks, out of which two repetitions were irrigated, and two were non-irrigated.We examined the yields of the varieties, the distribution of tubers according to size and their percentages, and the changes in specific parameters of quality and inner content due to irrigation. We studied the dry matter content, the starch content, the under-water mass, the amount of reducing sugars, the colour index of frying and the element contents of tubers.Summing up, it can be stated that among the agrotechnical year effect, variety and irrigation factors have considerable impact on potato yield quality and quantity. On the basis of our results, it can be stated that in potato production variety should be chosen in accordance with the aim of production and technology should be adapted to that specific variety.

The results of the study of promising potato varieties in Novosibirsk region (2016-2018) are presented. The objects of the study were 14 samples of potatoes, 10 of them were modern domestic varieties not zoned in the West Siberian region. An assessment of the quality indicators of potato varieties was carried out in comparison with the following zoned varieties: Red Scarlett, Nevsky and Tuleevsky. To obtain an early harvest (75 days after planting), the varieties Lomonosovsky (36 t/ha) and Reggi (39 t/ha) were recommended for the early ripening group. In the group of mid-early varieties, the variety Samba (35 t/ha) was noted; in the mid-season group, the varieties Fritella and Vympel were distinguished (early yield 32 t/ha). High productivity during harvesting in the early ripening group was noted in the varieties Lomonosovsky (42 t/ha) and Reggi (44 t/ha). The Samba variety (44 t/ha) stood out in the mid-early ripeness group. In the mid-season ripening group, the recommended variety is Gusar (46 t/ha), which exceeded the Tuleevsky standard by 4 t/ ha. Among the varieties of the early group of ripeness, high starch content was noted in the varieties Lomonosovsky (16.3%) and Reggae (17.4%). In the mid-early and mid-season groups, one variety was distinguished in each, Samba (14.4%) and Fritella (17.0%). In the early ripening group, the dry matter content of all varieties was higher than that of the Red Scarlett standard, in the mid-early group the highest indicator was observed in the Samba variety (22.9%). In the group of mid-season varieties, the samples Vympel (25.4%) and Fritella (25.8%) exceeded the standard. High field resistance to late blight (9 points) in the epiphytotic year (2017) was revealed in the varieties Gala, Nevsky, Gusar and Fritella.

Potatoes is the most important food crop, one of the main crops grown throughout the world. A way to improve the profitability of the potato industry is processing. The processing production requires special varieties of potatoes. Tests were carried out by the department of vegetable breeding «Agrarian scientific center of republic of Dagestan» in 2017-2018 with the purpose of study the effect of soil-climatic conditions of Dagestan highlands on dry matter and starch content in potato tubers for production of processed potato products. Processing of potatoes is one of the methods to increase profitability of industry. One of the quality indexes of the use of potato varieties for their processing is high level of dry matter and starch. As a result of the research, the following varieties were identified: high-yielding are Impala, Irbit, Zhukovsky Ranniy, Manifesto, Matushka, Nevsky, Primabella, Rosara, Silvana, Spiridon and Udacha; high dry matter content are Alena, Vektor, Dzhokonda, Desiree, Matushka, Nart, Primabella and Rossi; high in starch: Desiree - 23%, Vector and Primabella - 22.2% each. The results of the present investigation revealed that climate of the mountainous areas of Dagestan republic promotes the increase of dry matter and starch content in potato tubers by 3-4%.

AbstractA field experiment was conducted in the central highlands of Ethiopia to evaluate the performance of potato varieties for tuber yield and to identify a superior variety in tuber yield and yield components. The experiment was laid out in a randomized complete block design with three replications at two locations in the central highlands of Ethiopia during the 2017 main cropping season. The results of analysis of variance (ANOVA) showed the presence of highly significant (P<0.01) differences among varieties over all traits studied. The mean squares for location were also significant in indicating the influence of environments on the traits of the studied varieties. However, the interaction between variety and environment had no significant effect on the performances of the potato varieties to attain 50% flowering, specific gravity and dry matter content indicating a similar performance of these traits across all locations. The variety Belete produced the maximum total tuber yield of 32.8 t ha -1 and marketable tuber yield of 29.1 t ha-1. Conversely, farmers` variety Nech Abeba produced the minimum total tuber yield of 13.8 t ha-1 and marketable tuber yield of 8.4 t ha-1. For most tuber quality traits, viz., tuber specific gravity, dry matter content, starch percentage and total starch yield, varieties Belete and Menagesha were the maximum and minimum producers, respectively. Thus, it could be concluded that varietal and environmental variations as well as their interaction had considerable influence on tuber yield and the potato’s attributes.
