The Effect of ASN-320 Super Nano-absorbent on the Growth of Rapeseed at Different Irrigation Levels

One of the most important problems in agricultural production is water shortage. Application of absorbent materials can help usage of sporadic rain fall and cause more maintenance of water storage. This research was conducted as factorial based on a randomized complete design with three replication and four levelssuper nano-absorbent consisted of 0 (control), 0.2% super nano-absorbent (2 gram super nano-absorbent per kg of soil), 0.4% super nano-absorbent (4 g super nano-absorbent per kg of soil), 0.6% super nano-absorbent (6 gram super nano-absorbent per kg of soil) and three levels of irrigation; I1: FC- 0.85FC, I2: 0.85FC- 0.65FC, I3: 0.65FC- 0. 5 FC, was evaluated on the some physiological and morphological traits of rapeseed. These traits were affected significantly by super nano-absorbent. The highest stem diameter, plant height, chlorophyll index, number of pods and panicles, fresh and dry weight of the aerial part and 1000-seed weight were obtained with the use of more super nano-absorbent. (6 g super nano-adsorbent per kg of soil). Depending on the results, super nano-absorbent reduced damages caused by drought stress. The highest fresh and dry weights of the aerial parts of the plant using super nano-absorbent showed its role in drought stress conditions. In this study, it was found that although the growth indices decreased by reducing the amount of water, but by adding super nano-absorbent, the reduction was less than the non-use of super-adsorbent.
