Effect of nano fertilizer on quantity and quality yield of okra (Abelmoschus esculentus L.) in condition of drought stress
The present study was carried out in the form of split plots in a RCBD with three replications. Experimental treatments include drought stress at three levels of irrigation at moisture of field capacity, irrigation at 80% of field capacity and irrigation at 60% of field capacity as the main factor; And application of iron nano-chelate fertilizer at four levels of 0, 3.5, 7 and 10 kg.ha-1 as a sub-factor. The results showed that irrigation at field capacity and consumption of 10 kg.ha-1 resulted in the highest amounts of plant height, number of fruits per plant, fresh and dry fruit yield, biological yield, and mucilage and okra oil yield., no statistically significant difference was observed between the 10 and 7 kg.ha-1 fertilizer for the above traits., in stress conditions (moisture 80 and 60% of field capacity), the use of nano-fertilizers in comparison with the non-use of fertilizers led to the moderation of the effects of stress on the mentioned traits. So that only for the yield of fresh fruit, in treatment of moisture 80% of soil field capacity consuming 10 kg per hectare of fertilizer caused a 20.05% increase in yield compared to not using fertilizer. And this amount was 19.29% for moisture in 60% of soil field capacity. Also in the present study it was observed that the highest percentage of fruit mucilage was obtained from moisture treatment in 60% of field capacity and the highest percentage of fruit oil was obtained from irrigation treatment in soil field capacity moisture
