tailieunhanh - Seed yield and nutrient uptake of sunflower (Helianthus annuus L.) as influenced by different levels of boron and potassium in sandy loam soil

Nutrient uptake by sunflower seed increased with increasing levels of boron and potassium application. Seed nutrient uptake of N, P, K and B were , , kg ha-1 and kg ha-1 , respectively with K60, which is at par with B1K30 treatment. Maximum seed yield was obtained with treatment fallowed by , 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 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
