Effect of Bio-Stimulants on Quality Parameters of Garlic (Allium sativum L.) and Soil Health under Cultivation of South Eastern Rajasthan, India

An experiment was conducted at Vegetable Farm, Department of Vegetable Science, College of Horticulture and Forestry, Jhalawar (Rajasthan) during rabi season (2021-2022) on garlic (Allium sativum L.). The experiment was consisted ten treatments of bio-stimulants as soil drenching viz. (humic acid @ 4 g/L, humic acid @ 6 g/L., humic acid @ 8 g/L., seaweed extract @ 4 ml/L., seaweed extract @ 6 ml/L., seaweed extract @ 8 ml/L., vermiwash @ 10 ml/L, vermiwash @ 20 ml/L. and vermiwash @ 30 ml/L. and control) and laid out in randomized block design with three replications. The result of present study clearly indicates that quality parameters of garlic and soil health were improved with soil drenching of different bio-stimulants over control. The quality parameters of TSS (42.21 0Brix), dry matter content (42.54 %), crude protein content (7.05%), and pungency (10.39 μ mol/g), organic carbon (0.60) was significantly increased with application of humic acid @ 8 g/L over control. The maximum available nitrogen (342.74 kg ha-1), phosphorus (17.47 kg ha-1) and potassium (220.90 kg ha-1) was recorded in the soil after harvest of garlic with application of humic acid @ 8 g/L over control.
