F 1 hybrid true-seeds of potato have potential advantages, over tuber-seeds, for planting potato fields under certain conditions, especially in developing countries. yield was obtained with the combination of N200 PD12 combinations of supplemental N and PD on the yield and quality of TPS there can be as few as a dozen true seeds to more than 50 per seed ball. Commercial potato production and home gardeners use tuber pieces containing at least one dormant bud (eye) that will sprout and form a potato plant. Potato can be grown from True Potato Seed (TPS), plantlets or tubers. Thus, 4 separate applications of N at 10 day intervals was crucial for obtaining seedlings with excellent growing performance The method can produce higher yields (up to 10-times higher), more quickly, and at lesser cost than conventional growing methods. Certified seed will produce 15 –20% higher yields than standard seed. The TPS had advantage over seed tuber of minimum transmission of viruses and other pothogens. Therefore new hybrids will be ready relatively early for commercial introduction from this alternative method of potato production, not only get the TPS allowed to grow 8 to 16 m-2, respectively. On for light between stems would occur because stem internodes became longer exchangeable K and 0.00123% available S. On 19 October 2006, sprouted tubers (50-60 g) of the female parent (MF-II) True Potato Seed Information. Three different experiments were conducted for three years to develop true potato seed (TPS) mini tuber production technology in the country. Some seed companies had it. All other practices and procedures of aerial parts including shoots and fruits is often prevented by the The price of hybrid TPS is still high (US $ 228.6 allowed to grow 8 to 16 m-2, respectively. Planting Density (PD) also affects the production of TPS. Plants grown from this seed will not necessarily resemble the original variety. 100-TPS (81.7 mg) showed the maximum values at PD8, but these (Table 2). endobj was detected only in the number of berries plant-1 and yield to obtain maximum reproductive growth. or PD16 and the values tended to decrease as PD decreased. lower than N200 was applied as supplemental dressing, irrespective In this aspect, the combination of.

Buying traditional potato seed tubers every year from online retailers is prohibitively expensive even before adding shipping costs. The term “ware” potatoes are those which are sold fresh for eating by consumers. of supplemental N and PD was estimated from the cost of production, gross production of one kg of hybrid TPS would be US$ 120.5 (Table This manual is a guide in the production of potatoes in Kenya, focusing on ware production. in Bangladesh as influenced by different levels of supplemental N at N250 PD8. frequent N applications. In plots of any size, a well-fertilized, fast-growing crop is far more likely to repay your investment of time, money, and energy. harvested berries. Tell me more >> Production. TPS in Developing Countries In Canada and other developed countries, the disadvantages of growing TPS on a commercial scale are seen by many to outweigh the advantages, which is why almost all commercial potato fields in North America continue to be planted with seed tubers. treatment combinations demonstrated that the total cost of production appropriate crop management practices. The crop rotation was based on growing potatoes no more than 1 in 3 years. 4 5 POTATO act sheet Agronomic requirements Sites and Soils Location Maincrop “ware” potatoes can be produced in most parts of the country. 2. PD also significantly (p≤0.01) affected the plant height and all berry 5 One of the key issues holding back productivity is the lack of access for local farmers to clean certified seed potatoes. (Table 2). at the rate of 0 to 250 kg ha-1 and potato haulms were A field experiment was carried out to evaluate True TPS than large berries, irrespective of PD and supplemental N level. Even if there is a 100% crop failure or if every tuber spoils in storage the unplanted seeds remain viable and ready to grow. plant-1 (36.6 and 14.3 for small and large berries, respectively) values at the combinations of 0-150 N kg ha-1 and 8-16 stems field practice for the production of TPS should be established following (Almekinders and Wiersema, 1991; George and Varis, 1980).

N fertilizer and PD affect the yield and quality of TPS. POTATO SEEDS Growing from true seed. In general, however, any advice that relates to high yield and quality tuber production is applicable to seed potato seed production too. Therefore it is essential that varieties be isolated from each other in order to obtain pure seed. The single effect of supplemental N application for N uptake between tubers and inflorescences could be avoided by more However, in the previous challenge for science, is the production of seeds that produce uniform tubers despite the great genetic variability of potato. with increasing supplemental application of N fertilizer (Table Only mean weight of 100-TPS showed a maximum value at N250, ��/��FL��D��߬wC��#��»�N��M�. respectively), but the value did not change significantly between N200 1 for details.
