 ABSTRACT

A field experiment was conducted during Rabi, 2014 at college farm, college of agriculture, Rajendranagar, Hyderabad to realize the optimal dose of nitrogen and sulphur in safflower and to evaluate the effect of levels of nitrogen and sulphur on growth, yield and economics of safflower. The experiment was carried out with three nitrogen levels 0, 40 and 60 kg N ha-1 and three sulphur levels 0, 25 and 45 kg S ha-1 were laid out in randomized block design with factorial concept and replicated thrice. With respect to nitrogen levels, Viz. plant height (103.0 cm), leaf area index (2.36), dry matter accumulation (8751.8 kg ha-1), seed yield  (1458 kg ha-1), stalk yield (4133 kg ha-1) were recorded highest with 60 kg N ha-1 and it was significantly superior than 40 kg N ha-1 and 0 kg N ha-1. Among sulphur levels, significantly higher plant height (101.8 cm), leaf area index (2.31), dry matter accumulation(7851.4 kg ha-1), seed yield  (1444 kg ha-1), stalk yield (4114 kg ha-1) were recorded with 45 kg S ha-1 over  25kg S ha-1 and 0 kg S ha-1. higher gross returns () and net returns() realized with 60 kg N ha-1 and 45 kg S ha-1 and the B:C ratio () is also highest in case of treatments received nitrogen and sulphur with  60 kg and 45 kg respectively.

Key words: Plant height, Leaf area index, Dry matter accumulation, Seed yield, Stalk yield, Nitrogen levels, Sulphur levels.
