Post-harvest studies for efficient produce management in sugarbeet.

Sugarbeet roots desiccate and lose weight when allowed to remain in the field, scattered in small heaps. Losses in root weight were monitored at 24, 48 and 72 h for a sugarbeet crop harvested on 6 dates (2 Mar., 23 Mar., 2 Apr., 14 Apr., 23 Apr. and 14 May, in 1983-84 and 1984-85) and then allowed to lie in small heaps. Sucrose content in the roots was determined every 24 h. Losses increased with delayed harvesting: crops harvested in late-Apr./May lost 24-25% of their sugar, compared with 6-12% in Mar./early Apr. crops. Weight loss increased with the duration of field-lie from 24 to 72 h, with sharp increases (of approx equal to 25%) for the '14 May' crops. Losses in recoverable gross sugar yield were 0.9-1.3 t/ha in the latter part of the season and 0.32-0.15 t/ha for Mar. harvests in 1984-85 and 1983-84, respectively. Advancing the harvest period was most effective for reducing postharvest losses in sugarbeet in North-West Indian regions.
