“…The number of stolons per stem even decreased at a lower planting density (Table 3), thus resulting in a negative contribution to the increase of the number of tubers per plant. This seems to be in contrast with what was reported by Haverkort et al (1990), who found that plants from seed tubers with more stems per plant also tend to produce more stolons per plant. In in vitro derived plants at the low planting density, some of the earlier-produced stolons likely turned upwards to become stems, thus forming extra stems and reducing the number of stolons.…”

“…In crops from seed tubers, the number of tubers produced per plant is determined by the number of tubers per stolon, the number of stolons per stem and the number of stems per plant (Haverkort et al 1990). In in vitro derived plants, the higher number of tubers per plant at lower planting density was a direct effect of the increased number of tubers per stolon (Table 4) and the increased number of stems per plant (Table 3).…”

Commercial potato minituber production systems aim at high tuber numbers per plant. This study investigated by which mechanisms planting density (25.0, 62.5 and 145.8 plants/m 2 ) of in vitro derived plantlets affected minituber yield and minituber number per plantlet. Lowering planting density resulted in a slower increase in soil cover by the leaves and reduced the accumulated intercepted radiation (AIR). It initially also reduced light use efficiency (LUE) and harvest index, and thus tuber weights per m 2 . At the commercial harvest 10 weeks after planting (WAP), LUE tended to be higher at lower densities. This compensated for the lower AIR and led to only slightly lower tuber yields. Lowering planting density increased tuber numbers per (planted) plantlet in all grades. It improved plantlet survival and increased stem numbers per plant. However, fewer stolons were produced per stem, whereas stolon numbers per plant were not affected. At lower densities, more tubers were initiated per stolon and the balance between initiation and later resorption of tubers was more favourable. Early interplant competition was thought to reduce the number of tubers initiated at higher densities, whereas lateroccurring interplant competition resulted in a large fraction of the initiated tubers being resorbed at intermediate planting densities. At low planting densities, the high number of tubers initiated was also retained. Shortening of the production period could be considered at higher planting densities, because tuber number in the commercial grade > 9 mm did not increase any more after 6 WAP.

“…The maximum number of tubers per square meter of treated water by 50% (35.86) and the minimum number of tubers per square meter of treated water by 75% (34.06) was obtained. Havrkvrt and colleagues showed a high correlation between the number of tubers is ostolon (Haverkort et al, 1990). The numbers in each column treatments with a common letter are not significantly different according to Duncan test at 5% level are likely.…”

Potato is a major crop of Kermanshah province but shortage of water is important its production. To investigate yield and water use efficiency (WUE) of potato with trickle (T-Tape) and furrow irrigations, an experiment was performed in Kermanshah agriculture university research farm in 2007. The experiment was in complete randomized blocks design with 3 levels of irrigation-water amount (50%, 75% and 100% of cumulative evaporation from Class A pan) and irrigation methods (tape and furrow irrigations) with 3 replications. The results indicated that regardless to irrigation method, the maximum yield of potato (34.455 ton/ha) was achieved in irrigation water treatment of 100% and the minimum yield of potato (19.168 ton/ha) was achieved in irrigation water treatment of 50%. The effect of irrigation method on WUE was significant (P<0.01). The highest WUE (3.93 kg/m3) was belonged to 50% tape irrigation and the lowest WUE (1.2 kg/m3) was belonged to furrow irrigation. Tape irrigation caused an increase of 66% in WUE as compared to furrow irrigation. The difference in WUE between 50%, 75% and 100% irrigation treatment was not significant. The least percent of tubers smaller than 35 mm (26.42%) was obtained in tape irrigation method with 50% irrigation-water amount and the highest percent of tubers smaller than 35 mm (37.99%) was obtained in furrow irrigation method. The highest amount of tuber production (37.17%) in marketable size (tubers larger than 55 mm) was obtained in tape irrigation method with 100% irrigation-water amount. As the irrigation water increased, percentage of tubers larger than 55 mm increased. The effect of irrigation method on dry matter was not significant, but with reduction of irrigation water, the specific gravity of tubers of potato was decreased. It is suggested to use tape irrigation method, with irrigation water amount of 100% for producing potato.
