Potassium Dynamics under Sub Surface Drip Fertigation System on Banana cv. Rasthali | Chapter 06 | New Perspectives in Agriculture and Crop Science Vol. 1
Banana demands very high quantity of
potassium for its growth and development. It occupies an important place not
only with regard to its content in plant tissues but also for its role in
physiological and biochemical functions as many of the experimental results
shown that adequate supply of potassium fertilizers not only increased the
growth and yield of banana but also improved the quality of fruits, physiology
of the plant and induce resistance against biotic and abiotic stresses. 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.
