Abstract
"Performance of bioinoculants and bioformulations on growth, yield, and quality of
Turmeric (Curcuma longa L.)" was conducted at Vegetable Farm, College of Horticulture
and Forestry, Jhalrapatan City, Jhalawar, Rajasthan during Kharif season 2023-24 in Factorial
Randomized Block Design.
The experiment consisted of four levels of bioinoculants (Control, Azosprillum, VAM, PSB
@5 g each) and four levels of bioformulations (Control, Panchagavya, Amrutpani. Jeevamruth
@8 % each) with a total of 16 treatments. The experiment was laid out in a Factorial
Randomized Block Design (FRBD) with three replications each. Data were collected on
different growth, yield and quality contributing characters of turmeric. The bioinoculants and
bioformulation (VAM & Panchagavya) had significant effect on growth, yield and quality
individually and in combinations over control.
Bioinoculants significantly enhanced the growth of turmeric compared to the control.
Treatment with I2 VAM resulted in the maximum values for various growth, yield, quality and
soil attributes: plant height 78.23 cm and 107.45 cm at 90 and 180 DAS respectively, number
of leaves per plant 8.45 and 13.23, leaf width 13.67 cm and 17.20 cm, leaf length 35.87 cm
and 47.17 cm and pseudostem diameter 3.30 cm and 4.42 cm, length of mother rhizome 6.38
cm, diameter of mother rhizome 3.28 cm, weight of mother rhizome 64.57 g, number of
primary rhizomes per plant 8.33, length of primary rhizome 8.60 cm, diameter of primary
rhizome 2.61 cm, weight of primary rhizome 184.61 g, number of secondary rhizomes 12.21,
length of secondary rhizome 5.18 cm, diameter of secondary rhizome 1.75 cm, weight of
secondary rhizome 107.53 g, yield per plant 385.85 g, yield per plot 15.43 kg/plot and
estimated yield 642.81q/ha, dry weight of rhizome per plant 95.39 g, ascorbic acid content
0.1095 mg/100 g, curcumin content 2.09%, and antioxidant content 0.2222 μ mol
Trolox/100g, Treatment I1, which included Azospirillum, exhibited the highest values for
nitrogen content 312.81 kg/ha and I3 which is having PSB exhibited maximum values for
phosphorus content 23.00 kg/ha and for electrical conductivity 0.46 dS/m, and soil pH value
7.33 maximum values recorded in I0 (Control)
