dc.description.abstractExperiment on “Integrated nutrient management for irrigated and rainfed safflower (Carthamus tinctorius L.)’’ was conducted during rabi, 2013 at College Farm, Rajendranagar, Hyderabad. The soil of the experimental site was sandy loam, neutral in reaction, low in available nitrogen, medium in available phosphorus and high in available potassium. 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-1, S5: soil test based fertilizers + FYM @ 5 tons ha-1, S6: RDF + vermicompost @ 2 tons ha-1 and S7: Soil test based fertilizers + vermicompost @ 2 tons ha- 1 and replicated thrice. With respect to irrigations at critical stages, more plant height, number of branches, leaf area index (LAI), dry matter production per plant, yield attributes, seed, stalk yield and harvest index were recorded with irrigation treatment and it was significantly superior than rainfed planting. The number of days taken to attain rosette and 50% flowering was less under irrigation treatment. Significantly higher nutrient uptake, oil, protein content and oil yield were observed with irrigation treatment than rainfed planting and also highest net returns of 24145 and B: C ratio of 2.45 were obtained with irrigations at rosette and branching and flowering. With respect to organics and soil test based inorganic fertilizers, more plant height, number of branches, leaf area index (LAI), dry matter production per plant, yield attributes, grain and stalk yield were recorded with S7 (soil test based fertilizers + vermicompost @ 2 tons ha-1) and it was significantly superior to S6 (RDF + vermicompost @ 2 tons ha-1) followed by S5 (soil test based fertilizers + FYM @ 5 tons ha-1), S4 (RDF + FYM @ 5 tons ha-1), S3 (soil test based fertilizers) and S2 (RDF).

Degree : MASTER OF SCIENCE IN AGRICULTURE Faculty : AGRICULTURE Department : AGRONOMY Chairperson : Dr. K. P. VA NI University ACHARYA N. G. RANGA AGRICULTURAL UNIVERSITY Year of submission : 2014 Significantly higher nutrient uptake and protein content in seed was observed with S7 (soil test based fertilizers + vermicompost @ 2 tons ha-1) than rest of the treatments and also highest net returns of 28358 was obtained with in S7 but highest B: C ratio of 2.25 was obtained in S1 i.e., control. Interaction effect of plant height, number of branches, leaf area index, dry matter production, yield attributes, yield, quality parameters and net returns of safflower crop as influenced by main and sub treatments were found to be non-significant.en_US
