Effect of Organic Manure, Nutrient Solution Injection and Zn Foliar Application on Some Physical Characteristics of Date Palm Fruits cv. Zahdi

Abstract

A field study was carried out on private palm orchards located in Anbar province - Fallujah District, Al-Hassy region during season 2021 on date palm trees “Zahdi”. Cultivar trees were with age 30 years growing in clay soil to investigate effect of organic manure (cow manure) at levels (0, 10, 20 kg. palm−1), injecting nutrient solution under the trade name “Nutreeno” into the trunk at (0, 50 ml.Palm−1) and foliar application with Zn at (0, 500, 1000 mg. l−1). Results showed that all the studied traits recorded their superiority when soil application of organic manure at 20 kg.palm−1, whereas, nutrient solution injection at 50 ml.palm−1 gave the best results in the fruit weight, fruit diameter, fruit length and size, seed weight, bunch weight and yield. Spraying Zn especially with 1000 mg.l−1 achieved the highest values in all the studied characteristics compared to the control.
