Abstract
To evaluate the effects of nutrition spraying under low irrigation condition on qualitative characteristics of safflower, an experiment was conducted at the Agricultural Research Station, Sistan Farm, hn 2012-2013, using a split plot arrangement in a randomized complete block design with three replication. Different irrigation schedules, such as full irrigation, cut of time in heading-bud and flowering stage were considered as the main factors and different levels of nutrition spraying include; control (no consumption of nutrition spraying) iron Sulphate, zinc Sulphate, calcium Sulphate and combination of them were considered as subsidiary factors. The results showed that, the low irrigation had a significant effect on plant height, number of branch, auxiliary branches, harvest index, diameter stem, and number of heads, number of grain heads, 1000 grain weight, biological yield, seed yield and chlorophyll. The highest content characteristic, 1000 grain weight, and seed yield were found under full irrigation condition; the highest content, 1000 grain weigh, and seed yield were found under the cut off time flowering condition. The effect of different levels of spraying nutrition on the branch number, auxiliary branches leaf area, diameter stem index, number of heads, number of grain heads, 1000 grain weight, biological yield, seed yield, chlorophyll and oil were significant. So that the highest content of these characteristics was that of the combination of spraying iron Sulphate, zinc Sulphate, and calcium Sulphate. Therefore the interaction of low irrigation and spraying nutrition on plants' leaf number, protein and harvest index was significant. The highest content of plants' leaf number and harvest index was related to the full irrigation and the combination of spraying nutrition iron Sulphate, zinc Sulphate, and calcium Sulphate. The highest protein s' content was related to the cut off irrigation condition in flowering stage and the combination of spraying iron Sulphate, zinc Sulphate, and calcium Sulphate. Based on the findings of this study it could be said that the application of spraying nutrition expression in low irrigation condition has effective role in increasing qualitative factors, quantitative safflower, and cause increase yield.
