Effect of Irrigation Regimes and Silica Nanoparticles on Yield and Yield Components in Vivian Lettuce

Nano in agriculture improves plants in absorption of food, fuel and other items. The aim of this study was to investigate the performance and efficiency of water consumption under low irrigation regimes and silica nanoparticles. The present study was conducted in 1398 in the greenhouse of the Faculty of Agriculture, Shahid Chamran University of Ahvaz. In order to achieve the above objectives, the present study on lettuce plant (Vivian baby lettuce cultivar) in three water levels (75, 85 and 100 water requirements of the plant) and three application levels of nanoparticles including 0, 50 and 100 ml per 100 g Liter is done as root feeding in three repetitions. This design was completed in the form of shredded strip cards with a basic block design. Based on the results, dehydration stress on the total yield, harvest index, leaf area and leaf area has a significant effect on the level is likely to exist if it is valid for one year and shows only on weight. In this study, the effect of using nanoparticles on any of the studied indicators was not found to be significant. The combined effect of dehydration stress and the use of nanoparticles on total yield was significant at five times the probability level, but this effect was not found to be significant on root weight, leaf area index, harvest, root length and leaf area. Records more than the lowest total performance parameter for the I100F100 team equal to 87.88 grams and the lowest amount in the I85F50 team with 47 grams. The lowest leaf area and leaf area index are observed in I100F50 team, the minimum leaf area in I75F0 treatment and the minimum leaf area level in I75F100 treatment. The highest and lowest harvest indices in this research are 74.68 and 52.61 of the budget results, respectively. Maximum and minimum root weight occurred at full irrigation. Root weight in I100F100 treatment is 27 grams and in I100F0 treatment is 18.42 grams.
