Abstract:
The present investigation entitled “Influence of foliar spray of biostimulants and growth substances on vegetative growth of Kagzi lime (Citrus aurantifolia Swingle.) seedlings” was carried out at Regional Horticultural Research Station, ACHF, NAU, Navsari during 2019-20. The experiment was laid out in Completely Randomized Design with three repetitions and nine treatments viz. T₁ (19:19:19 @ 1%), T₂ (KNO₃ @ 1%)_, T₃ (Urea @ 1%), T₄ (BA @ 50 ppm), T₅ (GA₃ @ 100 ppm), T₆ (Novel⁺ @ 1%), T₇ (Panchgavya @ 3%), T₈ (Cow urine @ 3%), T₉ (Control). The foliar application of GA₃ @ 100 ppm (T₅) significantly influenced seedling growth as compared to other treatments which registered the maximum increment in number of leaves, increment in seedling height and increment in number of shoot at 10, 40 and 70 days after 2^nd foliar spray. However, this treatment was statistically at par with panchgavya @ 3% with respect to the increment in number of leaves at 10 and 70 days after 2^nd foliar spray and increment in seedling height at 40 and 70 days after 2^nd foliar spray. The highest leaf area (4.37 cm²) fresh weight (18.16 g) and dry weight (11.40 g) of shoot and survival percentage (92.20%) was also recorded in same treatment at 70 days after 2^nd foliar spray. The fresh weight of shoot (16.74 g) and survival (86.67%) were found at par with treatment panchgavya @ 3% (T₇) at 70 days after 2^nd foliar spray. So, on the basis of the results obtained under the study it can be concluded that the foliar application of GA₃ @ 100 ppm found better for enhancing seedling growth of Kagzi lime seedlings which was applied as a foliar spray at 25 and 50 days after transplanting.
