EFFECT OF SPRAYING MORINCA LEAF EXTRACT AND POTASSIUM ON GROWTH AND YIELD OF DATE PALM FRUITS BREAM CLASS

Abstract

The experiment was conducted in one of the private orchards in the Shatt Al-Arab city Al-Jeazera Al-Rabah District - Basra Governorate during 2022 growing season. To study effect of spraying with Morinca leaf extract , potassium solution and the interaction between them in some physical, chemical and production characteristics of date palm fruits of the Bream class , The extract of the Morinka solution was used at a concentration of (0, 15, 30)% and potassium at a concentration of (0, 1, 2)%, in two sprays, the first two weeks after inoculation and the second three weeks after the first spray. The results showed that the spraying treatment with Morinca extract at a concentration of 30% and potassium at a concentration of 2% was significantly superior in the physical characteristics under study (fruit weight, length, diameter, and stromal layer weight). The above treatment also excelled in chemical properties (soluble solids, reducing sugars, total sugars, vitamin C, and protein) compared to the comparison treatment. While the same treatment significantly reduced the percentage of sucrose in the fruits, The same treatment gave a significant increase in the percentage of nitrogen, phosphorus and potassium. The interaction between the two study factors had a significant effect on most of the studied traits.
