ABSTRACT Applying climate-smart agriculture practices, such as foliar spraying with growth stimulants and improving drought tolerance, seems to be a rational solution in drought-prone areas. The present study aimed evaluate irrigation regimes (I1: full-watered; I2: rainfed condition; I3: interruption of at the flowering stage; I4: seed setting stage) (S1: spray distilled water; S2: 250 Mm thiamin; S3: 1 ascorbic acid; S4: 100 ppm silicon dioxide nanoparticles; S5: 500 zinc oxide nanoparticles) on morpho-physiological traits rapeseed (Brassica napus L.). accelerated maturity lowest yield were recorded under I2 (1,389 kg ha-1), which was 38 % lower than obtained I1. greatest decrease evaluated traits, chlorophyll (48 %), leaf relative water content (25 number pods per plant (56 height (29 %) canopy spread (24 I2. performance related I3, respectively. treatments did not mitigate disruptive effects I3 growth; however, I1, use nanoparticles, nanoparticles thiamine increased some components.
