Influence of foliar nutrients on growth and yield of potato (Solanum tuberosum L.)

Abstract

To promote optimum growth and yield, the potato plant
requires a steady stream of the nitrogen along with an
adequate supply of phosphorus, potassium and micro
nutrients. Hence, the present investigation was undertaken
to evaluatetheeffect of foliar nutrients on growth, andyield
of potato at Vegetable Research Centre of GBPUA&T,
Pantnagar (Uttarakhand) during rabi season of 2017-2018.
The experiment was laid out in Randomized Block Design
consisting ofeleven treatments with four replications. During
the study, various observations in growth attributing
character viz. plant height, number of leaves per hill, number
of haulms per hill and stem diameter was recorded at dehaulming
stage whereas, fresh and dry weight of haulms
per hill were recorded at de-haulming stage. The yield and
yield attributing character such as grade wise number of
tubers, total number of tubers and total weight of tubers per
plot and per hectare was recorded at harvesting stage. The
findings of present investigation revealed that performance
of potato crop was significantly influenced by different foliar
application treatments. Among all treatments, 75% N of RDF
as basal + 2% foliar spray of 20:20:20 water soluble fertilizer
at 30 & 45 DAP (T11) was found best with respect to overall
plant growth and yield attributing characters.
