Abstract:
A field experiment was conducted at IHITC, Jaipur during two consecutive years i.e. 2018-19 and 2019-20. Higher yield and good quality is the priority of guava producer to fetch high income. The effect of foliar application of micronutrients (Zn, B and Fe; each at 0.2 and 0.4%) and plant growth regulators (NAA at 50 & 100 ppm and CCC at 500 & 1000 ppm) on quality (TSS, Titratable acidity, ascorbic acid, total sugar, reducing sugar, non-reducing sugar, sugar acid ratio and specific gravity) of guava cv. Allahabad Safeda was investigated. The increasing level of micronutrients and plant growth regulators significantly increased the guava fruit quality. Combined foliar application of 0.4%H₃BO₃ with 100 ppm NAA gave best results as compared to other combinations.
