Abstract

Plant growth regulators and nutrients are common in yield, production and quality attributes. In this experiments applying some novel plant growth regulators like, Jasmonic acid (JA) and brassino steroides (BR) are hormones involved in the regulation of many processes in plants and act (when applied as a pre-harvest treatment) to increase fruit bioactive compounds with yield potential. However, there is less literature available regarding the effect of pre-harvest treatment on citrus fruit yield attributes and production, which was the aim of the present study. The detailed knowledge of this novel plant growth regulator (brassino steroids/jasmonic acid) has become extremely important for various researchers, stakeholders and commercial growers. A field study was carried out on the effects of foliar application of growth regulators and nutrients on fruit retention and yield of acid lime (Citrus aurantifolia Swingle) on seven years old acid lime trees cv. Phule Sharbati with thirteen tre

Conclusion

Foliar application of T10- 2,4-D @ 15 ppm + KNO3 1% notably reduced fruit drop and enhanced fruit retention which significantly contributed to final fruit retention and fruit yield. The foliar spray of T3-Jasmonicacid @ 3 ppm in February, March and April in acid lime enhanced yield attributing fruit characters such as fruit set%, number of fruits plant-1, fruit breadth, fruit volume and titratable acidity, which ultimately increased yield plant-1. The application of GA3 @ 15 ppm + urea 1% increased the fruit length, number of seeds/fruit, TSS, ascorbic acid, total sugars, reducing sugars whereas T6-Brassinosteroid @ 15 ppm recorded maximum fruit weight.
