ABSTRACT
A field experiment was conducted at Agricultural Research Station, Ummedganj, Kota during kharif season of 2008 and 2009, to find out the optimum date of planting and INM practices for indigenous aromatic rice. The treatments consist of 3 dates of planting (10th July, 20th July and 30th July) and 5 INM practices (Control, 50% of RDF, 100% of RDF, 50% RDF + 50% N through farm yard manure (FYM) and 100% N through FYM) replicated thrice in split plot design. Aromatic rice planted on 10th July recorded highest grain yield (2.76 t ha-1) which was at par with the planting on 20th July (2.59 t ha-1) which declined by 23.18% due to 20 days delay in planting after 10th July. Among the nutrient management practices application of 100%RDF gave the highest grain yield 3.07 t ha-1) but it was at par with the 50% RDF + 50% N through FYM (2.93 t ha-1) However, higher net return (40792/- ` ha-1) and B: C ratio (1.98) was obtained with the application of 100% RDF through inorganic fertilizers.
Key words :
Aromatic rice, Dates of planting, Growth & yield parameters, INM practices.
