Abstract

The right combination of water and nutrients is the key for increasing the yield and quality
of produce. The availability of N, P and K nutrient was found to be higher in root zone area of
drip fertigated plot. Nitrogen and potassium moved laterally from point source up to 15 cm
and vertically up to 15-25 cm and P moved 5 cm both laterally and vertically and thereafter
dwindled. Fertigation frequency enables to reduce the concentration of immobile elements
such as P, K and trace elements in irrigation water. Fertigation of nutrients significantly increased
saving of fertilizer nutrients up to 40 per cent without affecting the yield of crops compared to
the conventional method of nutrient application.
