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. | Nội dung Text Seed yield and nutrient uptake of sunflower Helianthus annuus L. as influenced by different levels of boron and potassium in sandy loam soil
