Abstract

The soil sampling was done at emitting point (laterals placed at 25 cm depth of soil from surface) and 15 cm horizontally away from the emitting point of the same lateral. Similarly, the soil samples were also collected from 0-25, 25-50 and 50 – 75 cm depth of profile (vertical) between the drippers in 24 hours after fertigation at flowering stage of the crop. The soil was air dried, powdered and passed through a 2 mm sieve and stored in clean polythene bags.  The available potassium both in horizontal and vertical dimensions were mapped by using Surfer 7 software. The main aim of this study is to known potassium distribution at different depth in sub surface drip fertigation system in banana.
