The effect of irrigation periods and spraying of humic acids on the growth and production of okra under protected agriculture conditions.

NASIR ALZAMILI

The study was conducted in the green houses of faculty of Agriculture\ University of wassit under protected agriculture conditions during the winter season 2013-2014, due to the environmental conditions of Wassit to know the possibility of cultivating and producing okra, studying perfect irrigation periods using drip irrigation technology. The period between an irrigation and another was 3-5-7 days, and studying the effect of spraying humic acids with three different concentricities ;( 0, 2.5, 5) ml\l, and the overlap in growth and the produced okra which is locally known as batra. The research was conducted as a practical result using design of complete random sector D. B. C. R with three replicates. The results showed the possibility of cultivating okra with a commercial production and economic income ranging between 5-9.67 tons\h for different factors with an average of 7 tons\h. The results showed the significance of spraying humic acids in all vegetative qualities which positively affected the product. The results also showed the importance of irrigation each 7 days which gave the highest increase in the product. The results also showed the overlap between watering and spraying humic acids F2I2 which gave the highest increase in all qualities.
