Biennial bearing of apple trees is a problem with certain cultivars in many countries. For example, 'Summerred' is prone to produce high yields in one year followed by low yields in the next when grown in Norway.
Growers are facing increasing environmental, consumer and legislative pressures to avoid using peat. The UK has already used up 94 per cent of its available supplies and Defra recently set out plans to reduce peat use in English horticulture to zero by 2030 as part of the natural environment white paper.
It is increasingly common practice to take tomato cultivars with desirable fruit characteristics and graft them onto other cultivars that possess particularly desirable root characteristics. This requires the rootstock's hypocotyl - the portion of shoot below the cotyledons - to be cut through so that...
Calcium levels in apple are known to be associated with fruit storage potential and bitter pit. The potassium to calcium ratio is important for storage - the greater the ratio of potassium to calcium, the less the storability.
The shelf-life of some foliage pot plants is often limited by premature leaf fall, which suggests that they may be sensitive to ethylene in the atmosphere.
Aphids and related pests cause immense damage to a wide variety of crops.
The review presented here discusses dormancy, the mechanism that allows temperate-zone fruit trees to survive harsh winters.
Large quantities of phosphate fertiliser are added to watercress to produce high-quality commercially acceptable crops.
A recurring theme in recent research has been the need to use water efficiently in crop production (HW, 20 May and 15 July). The research reported here used time domain transmissometry (TDT) sensors, which can measure the amount of water in soil.
Damping-off was identified as a major problem on UK baby-leaf spinach in late summer 2008. Crops were affected mainly at the cotyledon stage and at canopy closure. In some cases losses were severe, with one grower losing a whole planting of a particular variety. Problems were less severe in 2009, following...
