Abstract: The present investigation entitled “Effect of foliar application of boron on fruit development, yield and quality of Aonla (Emblica officinalis) in prayagyaj agro-climatic condition” was conducted at Central Research field, Department of horticulture, Naini agriculture college, SHUATS, Prayagraj (U.P.) during the academic year 2022-24. Micronutrient (Borax, Boron, Nano Boron) include T₀ (Control or Water), T₁ (Borax 0.2%), T₂ (Borax 0.4%), T₃ (Borax 0.6%), T₄ (Borax 0.8%), T₅ (BoricAcid 0.2%), T₆ (BoricAcid 0.4%), T₇ (BoricAcid 0.6%), T₈ (Boric Acid 0.8%) T₉ (Nano Boron 0.2%), T₁₀ (Nano Boron 0.4%), T₁₁ (Nano Boron 0.6%), T₁₂ (Nano Boron 0.8%). The Growth,quality and Yield Parameters of the fruits of each treatment was done up to 90 days and allthe observations were recorded at every 30 days interval. The number of primary and secondary branches were recorded highest in the fruits treated borax 0.6% in T₃ during research work which were (10.66) and (13.72) respectively. Total soluble solids and total sugar contents had increasing trend during research periodand found highest (11.03) and (6.18) in T₃ treatment respectively at 90 days while ascorbic acid and titrable acidity had decreasing trend and mean value was found highest (504.88) and (1.58) in T₃ treatment respectively. On the basis of the above, findings the present investigation, it is concluded that plants treated with (T₃ Borax @ 0.6%) significantly improved yield and quality parameters of the fruit, titratable acidity (1.58%) were also recorded in fruits produced from the plants treated with (T₃ Borax @ 0.6%). However, maximum TSS (11.03 °Brix) and total sugars (6.18%) contents were obtained from borax @ 0.6% having maximum ascorbic acid (504.88 mg/ 100 g) contents. Followed by the treatment (T₂ Borax @0.4%) and B: C Ratio (6.44).
