Introduction- Plant growth regulators have also been used as an important component in agricultural production. Prior to the discovery of plant hormones. Plant growth regulators are now being used for more than one Million hectares of crop production worldwide per year (Lee, 2003).Plant growth regulator is a modern concept as a management practice for vegetable production. Numerous studies have been conducted to evaluate the influence of growth regulators on vegetables Crops. Crops. At present, different plant growth regulators such as GA3, NAA, 2, 4-D, IAA, IBA, 4-CPA, etc. at different concentrations are used in vegetables such as tomato, cabbage , cauliflower and okra for improving yield and quality.
Impact of application of the GA3 and NAA on tomato yield and quality :
Prasad et al . ( 2013) find out a tomato research with GA3 levels (20, 40, 60, 80 ppm) and NAA levels (25, 50, 75, 100 ppm).GA3 and NAA significantly apply the percentage of fruit collection, the number of fruits per plant and the fruit yield increased compared with the stock. Maximum fruit yield (48.36 t / ha) was obtained with closely followed application GA3 @80 ppm By NAA@100 ppm (47.42 t / ha) .
Influence of growth regulators at various concentrations on yields and improved quality for okra :
Okra (Abelmoschus Esculentus (L.) is an annual vegetable crop grown in the tropical and subtropical regions. Tropical corners of the world. Various activities like the use of growth will help to achieve this goal It appears that regulators like GA3, NAA, Miraculous etc. are the most efficient. GA3 was identified as Beneficial in okra, since it leads to the regulation of crop growth and development.
Impact of growth regulators at different concentration on yield and improvement of quality On the cabbage :
Cabbage (Brassica Oleracea var. capitata L.), a member of the Cruciferae family. The development of cabbage can be improved by the use of GA3. Cabbage was found to show rapid growth when treated with plant growth regulators (Islam et al., 1993).
