Abstract:
A field experiment was conducted at Agricultural Research Station (ARS) Bheemarayanagudi, UAS, Raichur, Karnataka during RABI 2018, to study the influence of foliar spray of nutrients and PGRs on growth and yield of safflower (Carthamus tinctorius L.) variety A-2. The experiment was laid out in RCBD and was replicated thrice. There were twenty treatments consisting of primary (NPK@(2%), secondary (Ca, Mg,S @0.5%), micronutrients (Fe Zn B and Mn @ 0.1%), salicylic acid (200 ppm) and cycocel (4000 ppm) alone or in combinations. Foliar spray treatments viz., CCC and SA were imposed at 40 and 50 DAS, respectively. The foliar sprays of essential nutrients were imposed twice at 60 and 80 DAS. Foliar spray treatment T19 representing combination of primary, secondary and micronutrients and SA and CCC spray, recorded significantly higher seed yield of and oil yield over control. The significant increase in the seed yield with treatment T19 may be due to the improvement in the yield traits namely number of capsules per plant-1, number of seeds capsule-1 and test weight which were largely influenced by the growth parameters like plant height, leaf area, branching, plant total dry matter accumulation and its partition into leaf, stem and capsule. Thus improvement in the yield was seems to be due to timely supply of essential nutrients and PGRs.
