To overcome the micronutrient deficiencies and meet the physiological and metabolic requirements of the spice
crops, the Institute developed crop specific designer micronutrient foliar formulations for the major spices
(Black Pepper, Ginger, Turmeric, Cardamom). It also successfully field-tested and commercialized the crop-specific
micronutrient formulations for the major spices. The Institute’s Ginger and Turmeric Formulations have already
received the Patents.
The micronutrient mixture for Black Pepper has been designed to fulfill the Black Pepper Crop’s requirement by
maintaining the optimal leaf nutrient ratio of secondary and micronutrients (especially, Mg, Zn and B) in the
leaf. The crop-specific Micronutrient Formulation is recommended for Black Pepper as a foliar spray (2 to 3
foliar sprays @ 5g per liter water) during spike initiation with the onset of monsoon and at monthly intervals
The Black Pepper Micronutrient Mixture’s application enhances the quality of the produce, while contributing to
the health of the vines through balanced nutrition. Over the years, the technology has reached the farmers in
about 8% to 10% of the cropped area. It increases the yield by 10% to 25% and improves the health and vigor of
vines. It is water soluble and compatible with common straight or complex fertilizers and increases bulk density
of the produce.
