02 December 2023, New Delhi: Besides Nitrogen-Phosphorus-Potash (NPK) (100:50:50 Kg/ha) the use of Sulphur @ 30-50 Kg/ha and Zinc sulphate @ 20 Kg./ha are recommended for enhancement in yield and quality. The use of specialty fertilizers (water soluble fertilizers) as NPK -19:19:19 @ 1 % at 30, 45, and 60 days after planting is recommended. This should be followed by NPK -13:0:45 @ 1 % at 75, 90, and 105 days after planting increases the yield and enhances the storability substantially. The fertigation in 10 splits is recommended for higher bulb yield.
How to use chemical and organic fertilizer ratio in garlic at 50% and 70%
For garlic integrated nutrient management is recommended. It can be a combination of 50% chemical fertilizer and 50% organic fertilizer or 70% chemical fertilizer and 30% organic fertilizer. For 50% chemical fertilizer, use (NPK @ 50:25:25 Kg/ha + Sulphur @ 25 Kg./ha + Zinc @ 10 Kg/ha + Azospirillum or Azotabactor @ 10 Kg./ha + Phosphate solubilizing bacteria @ 10 Kg/ha). For 70% chemical fertilizers, use (NPK @ 30:15:15 Kg/ha + Suphur @ 15 Kg./ha + Zinc @ 6 Kg/ha + foliar spray of Polyfeed @ 1 % at 15, 30, and 45 days after planting followed by Multi-K @ 1 % at 60, 75 and 90 days after planting). These doses of 50% and 70% chemical fertilizer will not reduce yield but will improve soil health in comparison to the standard 100% chemical dose (NPK @ 100:50:50 Kg/ha + S @ 50 Kg/ha +Zn @ 20 Kg/ha).
The farm application of GA3 @ 25 ppm at 45 & 60 days after planting has been recommended to enhance the yield of garlic and improve the quality under the Nashik conditions of Maharashtra and Karnal conditions of Haryana.
Use of Pendimethalin @ 3.5 l/ha + one hand weeding or Oxyfluorfen @ 0.25 Kg a.i/ha + one hand weeding is recommended for effective control of weeds in garlic.
Irrigation at 1.5 CPE (Cumulative Pan Evaporation) is recommended for a higher yield of quality garlic bulbs. Drip irrigation is recommended in garlic grown on a raised bed to get a higher bulb yield.
