Abstract
Influence of Sulphur and Phosphorus Levels on Growth and Development: A Field Experiment yield of Safflower (Carthamus tinctorius L)â. var. âISF-764â was conducted at Crop Research Farm during Rabi season 2021-23. Department of Agriculture Sciences and technology United University, Prayagraj (U.P.). The soil of the experimental plot had a sandy loam texture, was almost pH-neutral (7.5), had a low organic carbon content (0.50%), and was readily available. N (228.59 kg/ha), available P (29.80 kg/ha) and available K (125.21 kg/ha). The experiment was laid out in randomized block design with nine treatments consists three level of S 20, 30, 40 kg/ha and three level of P 30, 40, 50 kg/ha with control (Farmer practice) were replicated thrice. Results obtained that higher plant height (173.33 cm), Number of branches (19.27), dry weight (117.89 g/day), yield attributes and yield viz., seed yield (2.20 t/ha), stover yield (2.98 t/ha) and Hi (42.44 %) were recorded with the application of 40 kg/ha S + 50 kg/ha P, economics viz. however, higher gross return (113804.07 INR/ha), net return (77799.97 INR/ha) and B:C ratio (2.16) was observed when 40 kg/ha S and 50 kg/ha P were applied. Application of 40 kg/ha S with 50 kg/ha P was therefore more productive and financially viable.
