Abstract:

A field experiment was laid out in factorial randomized block design with 16 treatment combination comprising of four levels of boron and four levels of potassium viz., (B0K0), (B0K15), (B0K30), (B0K60), (B0.5K0), (B0.5K15), (B0.5K30), (B0.5K60), (B1K0), (B1K15), (B1K30), (B1K60), (B1.5K0), (B1.5K15), (B1.5K30), (B1.5K60) to investigate the influence of application of different levels of boron and potassium with recommended dose of N and P fertilizers on sunflower (Helianthus annuus L.) hybrid,GK-2002 to find out the nutrient (Nitrogen, phosphorus, potassium and boron) uptake and optimum dosage of boron and potassium to increase the sunflower seed yield. In the present investigation, sunflower shoot uptake of major nutrients like N and P were significantly influenced by the application of B and K at 60 and 90 DAS. Nutrient uptake by sunflower seed increased with increasing levels of boron and potassium application. Seed nutrient uptake of N, P, K and B were 43.83, 11.85, 13.65 kg ha-1 and 33.24 kg ha-1, respectively with B1.5 K60, which is at par with B1K30 treatment. Maximum seed yield was obtained with B1.5K60 treatment fallowed by B1.5K30, B1K30 and B1K60. Boron and potassium levels and B x K interaction were found significant in both shoot and seed. Even though highest seed yield with B1.5 K60 treatment was recorded, B1K30 treatment showed was economically beneficial.
