Nutrient content and uptake of basmati rice as influenced by organic and inorganic sources of nutrients

Abstract

Performance of organic sources i.e. vermi-compost (VC), poultry manure (PM), farm yard manure
(FYM) in combination with chemical fertilizers and sole chemical fertilizers with 100% recommended
dose of fertilizers (RDF) i.e. 120:60:60 NPK kg ha–1 and 125% RDF were evaluated in terms of nutrient
content and nutrient uptake of basmati rice at crop research centre of Sardar Vallabhbhai Patel
University of Agriculture and Technology, Meerut, India, during kharif - 2013 using randomized
block design (RBD). Results revealed that highest nitrogen, phosphorus and potassium content in
grain and straw and their uptake in basmati rice were recorded with application of 125% RDF
through inorganic source of nutrient over other treatments. The highest grain (4.56 t ha–1) and
straw yield (6.49 t ha–1) was also recorded with 125% RDF through inorganic source of nutrient but
it was statistically similar to the treatment containing 50% RDF through inorganic sources + 50%
through PM.
