Abstract:
The Indian mustard variety viz. varuna were grown in field under randomized block design with three replications and 6 treatments. The plots were maintained under rain-fed condition. The spray of brassinolide and salicylic acid was taken during flower initiation and after 50 per cent flowering stage. Different morpho-physiological parameters were recorded at flower initiation and 50 per cent flowering stage. The results showed that different morpho-physiological parameters like plant height, number of primary branches, secondary branches, leaf area per plant, dry matter accumulation, relative water content, membrane stability index and showed maximum at hormonal spray of brassinolide at 20 ppm, which is followed by hormonal spray of salicylic acid at 200 ppm. The results of the study finally concluded that all the growth and morphological parameters increased with respect to brassinolide foliar spray even under rainfed conditions and suggested that the variety varuna is suitable for cultivation under rainfed conditions with the foliar spray of both plant growth regulators.
