Effect of Planting Density and Size of Potato Seed-Minitubers on the Size of the Produced Potato Seed Tubers.

Influence of Plant Density and Genotype on Potato Minituber Production from Microshoots and Microtubers

“…In accordance with these results, Karafyllidis et al (1997) obtained higher number and yields of minitubers from the culture of microtuber at high density, while plants at low density had larger minitubers. Similar results were also reported by Georgakis et al (1997), Love and Thompson-Johns 2006). In recent report, (Sharma et al, 2014) found that planting at density of 150 microtubers/m 2 gave more number of minitubers than at 66 microtubers/m 2 , and minituber size was higher at lower planting density.…”

“…However, with the increase in planting density, more small size minitubers were produced as reported by Karafyllidis et al (1997). Similar results were also obtained by Georgakis et al (1997) Love and Thompson-Johns (2006). However, in a hydroponic growing system, Farran and Mingo-Castel (2006) showed that low planting density (60 plants/m 2 ) produced tubers, four times the yield at high density (100 plants/m 2 ).…”

Effect of Fertilizers on Growth and Productivity of Potato-A Review

“…There was also decrease in the dry matter beyond 200 kg N/ha, which might be due to difference in relative maturity of tubers [27]. The results of the experiment conducted by Georgakis et al during the year 1997 showed that increase in nitrogen rates up to favorite point led to increase in tuber yield per unit area beyond which the rate decrease [28]. This might be due to the fact that vegetative growth of the aerial parts can increase with application of more Nitrogen and hence, inhibit transferring photo synthetically matters into the storage parts (tubers).…”

Optimum In-row Distances for Potato Minituber Production

“…These minitubers are mostly between 5 and 15 mm in diameter and have the potential to produce complete potato plants. Karafyllidis et al (1997) and Georgakis et al (1997) found that the minituber size generally has no effect on their yielding capacity, although small minitubers (10 mm or less in diameter) may have limitations for open-field multiplication.…”
