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 afterwards.
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.
