The effect of tuber seed cutting, tuber seed storage temperature and nitrogen fertilization in potato production

In the present work, two treatments of die seed tuber, seed cutting and seed storage temperature were studied, with four levels of nitrogen applied once, at planting time. The cut seed gave a better yield in the medium size tubers, 37.8 T/ha and the non-refrigerated seed give a slight increased yield iii this class. The response to nitrogen was better, with 150 kg/ha giving the higher total yield and the higher yields of the two largest tuber classes considered. The effect of cutting the seed tuber must be studied again, as in the present experiment, the total and the commercial yield was higher with cut than with whole seed. With cut seed it is possible to have a large reduction on the production com of the potato crop, as we reduce the cost of the seed tuber by nearly a half, it is only necessary to take into account the cost of cutting the tuber.
