Description A field experiment was conducted during kharif, 2010 in University of
Agricultural Sciences, Dharwad “H” block of Main Agricultural Research Station to
evaluate the influence of integrated nutrient management practices on growth, nutrient
uptake, yield and quality of potato. Totally 11 different treatments consisting of
different organic and inorganic fertilizers, both alone and in combination have been
tried. Among the different integrated nutrient management practices, application of
100% RDF + 25 tonnes of FYM ha-1 and 75% N through RDF + 25% N through
sheep manure +25 tonnes of FYM ha-1 were significantly superior over the other
treatments for all growth, yield, quality and nutrient uptake parameters and economics
of production. Application of 100% RDF + 25 tonnes of FYM ha-1 has resulted in
higher plant height (46.33 cm), number of leaves and number of shoots (40.47 and
5.20, respectively), leaf area (113.19 cm2), leaf area index (3.79) and leaf area
duration (69.48 days), higher uptake of major nutrients viz., nitrogen,
phosphorus and potassium (165.28, 125.60 and 152.02 kg/ha, respectively) in potato
plant. Yield attributing characters viz., yield per plant (223.33 g), mean tuber weight
(65.23 g), tuber girth (14.32 cm), marketable yield (11.91 t/ha), total tuber yield
(12.60 t/ha) and highest crude protein content in tuber (8.98%) was found with the
application of 100% RDF + 25 tonnes of FYM ha-1 and was on par with the
application of 75% N through RDF + 25% N through sheep manure + 25 tonnes of
FYM ha-1. Apart from this the highest net income (Rs. 70164) and benefit cost ratio
(2.46:1) was also realized with the application of 100% RDF + 25 tonnes of FYM ha-
