Other claims from this paper (19)
- Intervention effect In field experiments in Northumberland, UK, early sowings reached a leaf area index of 3.5 earlier than late sowings.
- Intervention effect Early sowings significantly outyielded late ones.
- Association There was a close relationship between total dry weight, bud dry weight and the amount of intercepted solar radiation.
- Observation The efficiency of energy conversion of radiation for total dry weight was 1.28, 2.05 and 2.11 g/MJ in 1983, 1984 and 1985.
- Observation The efficiency of energy conversion of radiation for bud dry weight was 0.97, 0.83 and 0.67 g/MJ in 1983, 1984 and 1985.
- Observation Harvest index ranged from about 25% in 1985 to 40% in 1984.
- Intervention effect Increasing plant density from 2.22 to 6.66 plants/m2 advanced and increased maximum LAI and total and bud dry weight per m2.
- Intervention effect Increased plant density had an adverse effect on the distribution of dry matter.
- Intervention effect The onset of rapid bud growth was advanced by early sowing.
- Intervention effect Early-sown crops produced more buds than late-sown ones because of a longer growing season.
- Intervention effect Plant density had a large effect on the number of buds per m2, which was almost directly proportional, while buds per plant were not severely affected.
- Observation Total bud fresh yields averaged over all sowing dates reached 17 t/ha in 1983 and 31 t/ha in 1984.
- Observation Yields of buds in the freezing grade (20-30 mm) increased rapidly between late September and early to mid-November, reaching 7.5 and 8.8 t/ha in 1983 and 1984.
- Observation The difference in freezing-grade yields between the two years (1.3 t/ha) was much less than the difference in total yields (14 t/ha).
- Observation The average dry matter content of buds declined by 2-5 % from October to January.
- Observation Low planting densities gave high yields of small buds at early harvests, but denser planting gave higher yields at later harvests.
- Intervention effect Late sowing in 1983 restricted bud growth, resulting in a higher proportion of buds in the freezing grade.
- Mechanism Individual bud size was restricted as a result of competition for assimilates.
- Recommendation The experiments confirmed that manipulating sowing date and planting density is an effective way of spreading harvest date through the season for fresh market and processing.
