| الوصف: | Foliar application of two plant growth regulators (PGR)-brassinolide at 0.5 ppm, gibberellic acid at 10 ppm and one complex fertilizer NPK 19:19:19 at 1% concentration were tested alone as well as in combination with control (double dose of fenoxaprop-ethyl) and absolute control (normal dose of fenoxaprop-ethyl) against herbicide stress to rice during Kharif 2015 and 2016. The treatments were given 5 days after application of fenoxaprop-ethyl as foliar spray Among the PGRs and nutrients, tank mix application of brassinolide at 0.5 ppm + NPK 19:19:19 at 1% recorded the lowest incidence of phytotoxicity (1.2) at 30 days after application and gave the highest grain yield (6.12 t/ha), net returns (‘ 49,431/ha) and benefit: cost ratio (1.32). Grain yield was more (5.92 to 6.12 t/ha) in brassinolide treated plot than that of gibberellic acid (5.81 to 5.83 t/ha) indicating more effectiveness of brassinolide than gibberellic acid in mitigating herbicide stress. Use of plant growth regulator and nutrient prevented 25.9% yield loss due to herbicide stress in rice. |
