Abstract
Chillies (Capsicum annuum) are a spice crop with great medicinal value of its biochemical ingredients. Its high antioxidant value along with good nutritional properties. Foliar application of Salicylic Acid may stimulate various plant physiological parameter i.e., stomatal activity, ions uptake, seed germination, leave membrane response to electrolytes and growth rate. Salicylic Acid (SA) is known as a molecule that is participated in physiological processes in chillies, plant tolerance and resistance to abiotic and biotic stresses. Ascorbic acid possesses antioxidant properties, has positive impact on flowering and expounds effective plant defense system against pesticide toxicity. Moreover, ascorbic acid is effective chemical to mitigate the destructive impacts of salt stress. All the treatments improved the yield, fruit length and fruit width as compared to control treatment. Although, various treatments, salicylic acid and ascorbic acid combination showed the maximum plant height (80.3 cm), shoot weight (161 g), root weight (47.1 g) and pericarp thickness (1.99 mm) in treatment T9 variety of V4. Results declared that foliar spray of plants growth regulators increased the carbohydrates, protein, fiber and ash content. Results declared that foliar spray of plants growth regulators increased the carbohydrates, protein, fiber and ash contents. Furthermore, Biochemical attributes and Enzymes like proline (19.1%), SOD (1.40ug-1Fw), POD (17.9 ug-1Fw g) and CAT (6.15ug-1Fw) were significantly improved in plants sprayed with salicylic acid (SA) and ascorbic acid (AA) at T9 treatment. The objective of this study was to evaluate the effect of foliar application of ascorbic acid and salicylic acid on the yield and biochemical traits of hybrid chillies. Generally, the highest values were obtained from T9 treatment application of SA and AA combination. Based on these findings, the SA and AA treatments may help alleviate the positive effect on the growth of Chillies.
