RGT Planet Feed Barley
- Reliable yielding spring barley
- Dual-purpose feed and malting barley
- Consistent yield performance across all growing regions, especially the lower North Island
- Good straw strength compared to other cultivars
Description
RGT PLANET is a consistent and reliable yielding feed and malting barley variety, bred in France by RAGT and developed in New Zealand in conjunction with RAGT New Zealand as head licensee and PGG Wrightson Grain (PGW Grain).
YIELD
RGT PLANET has yielded consistently over the past ten years in CPT spring trials. While not the top performer at all sites, RGT PLANET is a reliable cultivar across multiple autumn and spring locations.

RGT PLANET produces a rare combination of yield and excellent grain quality.
TIME OF DRILLING
RGT PLANET is an established autumn drilled barley, although drilling is not recommended until early May owing to the risk of frost damage during flowering. It can be drilled through the winter into the spring, although sowing through the coldest weeks of June and July is not recommended, especially in heavy soils prone to waterlogging. Spring sowing is typically from early August to late September, except in the lower North Island, where drilling can be as late as November.

SEED RATE AND TILLERING CHARACTERISTICS
RGT PLANET is a medium to high tillering variety, and target plant populations should be within the standard PGW Grain barley seed rate guidelines.
SOIL TYPE, ROTATION AND GEOGRAPHY
RGT PLANET can be planted on all soil types where barley is already grown and can be grown as a first or second-year cereal. As a second-year cereal, barley is generally more take-all tolerant than wheat, however, yield will be lower than a first-year barley crop.
DISEASE RESISTANCE
RGT PLANET is mostly resistant to powdery mildew, and moderately resistant to scald. However, it is moderately susceptible to net blotch and leaf rust. Considering this disease profile, RGT PLANET will need a moderate to robust fungicide programme where there is pressure for leaf rust and net blotch. In the 2022/23 PGW Grain fungicide trial, RGT PLANET produced a moderate untreated yield and fungicide responses of 2.0-3.8 t/ha from an autumn sowing. Please contact your local PGW Representative for site specific recommendations.

STRAW STRENGTH AND HEIGHT
RGT PLANET is a medium to tall, stiff-strawed cultivar. In Europe, it rates high for brackling resistance, and the New Zealand experience is similar. Autumn sowings will typically require plant growth regulator (PGR) investment, especially under irrigation. Some spring crops may not need a PGR programme. The actual programme is determined by a combination of local conditions, management and yield potential. As with any cultivar, do not apply if the crop is under any form of stress. Please contact your local PGW Representative for site specific recommendations.
