FOLIAR FEEDING Another Successful Way of Feeding Plants
نویسنده
چکیده
Plant nutritionist have traditionally considered the obvious way to feed plants is through the soil, where plant roots are meant to uptake water and nutrients, but in recent years foliar feeding has been developed to supply plants with their nutritional needs. The development of pressurised irrigation equipment such as drip irrigation has promoted the need for water-soluble fertilisers, as clean and purified as possible in order to diminish the possibility of emitters clogging. It is not really clear when foliar feeding started, but after the development of water-soluble and liquid fertilisers farmers have begun to use these fertilisers with sprayers, the same as it is used with applications of pesticides. At the beginning, this technique of spraying nutrients was used for correcting deficiencies of minor elements. However, fast curing has shown that plants can absorb some elements through their tissue. As a result, foliar feeding has gone through further development. These days foliar feeding is considered among the major techniques used for plant nutrition, supplementing the ground application. In this article I will review the whole concept of foliar application when it should be considered, how nutrients actually penetrate plant tissue, and some technical limitations of this method of plant feeding.

Field and laboratory studies were conducted to examine the relationship between foliar feeding damage caused by striped cucumber beetle, Acalymma vittatum (F.) (Coleoptera: Chrysomelidae), and yield of pumpkin, Cucurbita pepo L. (var. Spookie). In field trials in 1996 and 1997, plants were artificially infested with varying numbers of beetles at the cotyledon-, first-, second-, or third-leaf st...

1. As herbivory often elicits systemic changes in plant traits, indirect interactions via induced plant responses may be a pervasive feature structuring herbivore communities. Although the importance of this phenomenon has been emphasised for herbivorous insects, it is unknown if and how induced responses contribute to the organisation of other major phytoparasitic taxa. 2. Survey and experimen...

Prior host feeding experience influences ovipositional but not feeding preference in a polyphagous insect herbivore
Black vine weevils, Otiorhynchus sulcatus (Fabricius) (Coleoptera: Curculionidae), are globally-distributed polyphagous pests of many horticultural crops. We investigated how adult weevils were affected by host switching and, in particular, how host plant species nutritional and defensive chemistry affected subsequent host plant species selection and oviposition. Adults were fed one of three ho...
