In such cases seed tubers were dug up and transferred to a cooler place (see next section). Farmers were prepared to accept some late blight in tubers if other characteristics were favourable. Variation in soil temperatures accounted for 96 and 99 % of the variation in tuber yield at varied population densities and sowing dates, respectively. It can be concluded that a population of tubers sorted by minimum diameter will also be sorted by mass according to these relationships and variances. At natural maturity, tubers from the whole trial were harvested immediately and weighed to determine tuber yield (kg). Fresh tubers can be peeled, chipped, dried and milled into -our. Absent from private sector research, not surprisingly, are many crops cultivated by the world's poor, including small-grain cereals, tubers and legumes. Although post-harvest losses were slightly reduced after four months of storage by both treatments, this had no effect on tuber yield. There was a tendency for borderline tubers to pass along the rollers slightly too far and fall into the size above the correct category. In these three cultivars, therefore, tuber initiation started 19+28 d after emergence of the sprout. An infested tuber was defined as one with visible tunnelling damage, regardless of the presence or absence of larvae. A digital imaging technique was developed to quantify accurately the incidence of internal browning in potato tubers. The absence of a direct correlation between trapped adults and tuber infestation in sandy soil may be due to lack of statistical power. These examples are from corpora and from sources on the web.
