Yield and economics of safflower as influenced by inm under irrigation and rainfed planting

A field experiment on “Yield and economics of safflower as influenced by INM under irrigation and rainfed planting” was conducted during rabi, 2013 at College Farm, Rajendranagar, Hyderabad. The experiment was laid out in a split plot design with two main treatments viz., M1: irrigation at rosette, branching and flowering, M2 : rainfed planting; and seven sub treatments viz., S1 : Control (no fertilizers), S2: RDF, S3: soil test based fertilizers, S4: RDF + FYM @ 5 tons/ha, S5 : soil test based fertilizers + FYM @ 5 tons/ha, S6: RDF + vermicompost @ 2 tons/ha and S7: Soil test based fertilizers + vermicompost @ 2 tons/ha and replicated thrice. With respect to irrigations at critical stages gives higher seed yield, stalk yield, gross returns, net returns and BC ratio were recorded with irrigation treatment and it was significantly higher than rainfed planting. With respect to organics and soil test based inorganic fertilizers gives higher seed yield, stalk yield, gross returns and net returns were recorded with S7 (soil test based fertilizers + vermicompost @ 2 tons/ha) and it was significantly superior to S6 (RDF + vermicompost @ 2 tons ha-1) followed by S5 (soil test based fertilizers + FYM @ 5 tons/ha), S4 (RDF + FYM @ 5 tons/ha), S3 (soil test based fertilizers) and S2 (RDF). BC ratio recorded higher with S1 (control) treatment. Interaction effect of seed and stalk yield and economics of safflower crop as influenced by main and sub treatments were found to be non-significant.
