“…Transplanting techniques have been widely researched in sugar beet, an economically important crop and a close relative of fodder beet, both being of the species Beta vulgaris. Research trials have particularly focused on increasing sugar yield potential, as this crop is strongly responsive to length of growing season (Dillon et al 1972;Theurer & Doney 1980;Hussain & Field 1991;Karbalaei et al 2012), and have also focussed on weed management (Kouwenhoven et al 1991). Although increased yield was a common factor in these trials, the value of the increase in yield compared with the increased cost of these early transplant production systems has not justified conventional sugar beet production to change to establishment via transplants.…”

Fodder beet has become a popular winter feed for all stock classes in New Zealand. However, poor crop establishment frequently leads to either significant loss in yield, through below-target plant populations, weed competition, or crop failure. This study demonstrates that establishing the crop from transplants, common in the vegetable industry, is one way to achieve a uniform plant population and reduce weed competition through early establishment of canopy cover. The most significant effect of transplant establishment is that the target plant population is readily achieved.

Punch planting, flame weeding and stale seedbed for weed control in row crops

Punch planting is introduced as a new method to reduce weeds within rows in organically grown crops. In this method a hole is punched in the soil, and a seed is dropped into it, without seedbed preparation and soil disturbance outside the hole. In 2 years, punch planting with flame weeding, normal planting with flame weeding and normal planting without flame weeding were compared in fodder beet for five planting dates. Each planting date represented a lag-period since establishment of the stale seedbed. Over all planting times and years, punch planting with flame weeding reduced intrarow weed densities by 30% at the two to four leaf stage of fodder beet compared with normal drilling with flame weeding. Punch planting with flame weeding also reduced intra-row weed densities by 50% compared with normal drilling without flame weeding. In general, there was no improved performance of punch planting with flame weeding over years by later planting, but delayed planting reduced intra-row weed densities significantly. Over 2 years, 240 day degrees Celsius (4 weeks) planting delay reduced intra-row weed densities in the range of 68-86% depending on plant establishment procedure. Punch planting with flame weeding offers a promising method of weed control in organic farming.
