Drip Fertigation

A field experiment was conducted during two successive growing seasons, 2014/2015 and 2015/2016 to evaluate the effect of different fertilizer application methods on date palm (Phoenix dactylifera L.) yield and fruit quality grown in sandy soil. Strip block statistical design with three replicates was used on four selected date palm cultivars (Madjool, Sacchari, Kheyarah and Sggaa) as main treatments and three fertilizer application methods (Hydraulic injector, Surface Broadcast and By-pass tank) as sub main treatments. The results revealed significant increases in yield and fruit quality when using continuous fertigation by Hydraulic injector comparing with broadcast and By-pass tank traditional methods. The average of two seasons results indicated also that using Hydraulic injector method maximized Sacchari date yield by producing 69 kg per tree and resulted in the best water productivity (1.06 kg m-3). The use of fertigation method has significantly increased the date palm productivity by 81, 51.2, 66.7 and 72.8% in comparison to the traditional Surface Broadcast method for Madjool, Sacchari, Kheyarah and Sggaa, respectively. The mean fruit weights were significantly increased by 56.5, 72.1, 90.2 and 68.8% when using the hydraulic injector compared to the traditional broadcast application method for pervious date palm cultivars, respectively.

This study was carried out during three successive seasons 2011, 2012 and 2013 at a private orchard located in Al- Hello in Ajman Emirate (UAE). The experiment was designed to study the effect of organic manure and NPKS as soil application on yield, fruit quality, and fruit mineral nutrient content of Khenazi date palm cultivar grown in sandy soil. Fertilization treatments consisted of N1, 600g or N2, 1000g (urea 46%N), P 800g (triple superphosphate, 48% P2O5), K 1200g (potassium sulphate, 50% K2SO4) and S 700g sulphur (90% granular S), in addition to organic manure. Al experimental trees received 100g mixture of micronutrients, with the exception of the control. The results showed that combination treatments and organic manure significantly affected fruit weight, flesh weight, fruit volume, moisture content and fruit TSS. Application of different fertilization treatments significantly affected yield components of fruit, number of fruits/strand, fruit number/bunch, fruit set percent and total fruit yield / palm. The study revealed that combination of fertilizers improved fruit nutrient content of N, P, K, Ca, Mg, Fe, Zn, Mn and Cu. Moisture and TSS% content, number of fruits/strand, number of fruits/bunch, fruit nutrients content of Fe, Mn and Zn were significantly different due to the application of N1+K+S.

Significant Difference

This study was conducted during the two growing seasons (2018 and 2019) in Date Palm Trees Station-Al-Hussinya District-Horticulture and, Department of Forestry, Ministry of Agriculture, Karbala Governorate. Two cultivars of date palm trees Zahdi and Khistawi were studied. The 27 palm trees for each cultivars were randomly selected, homogeneous in vegetative growth and similar in size and shape. The results showed that the Zahdi cultivar recorded a significant increase in the content of chlorophyll and proline which reached 0.939 mg.g-1 and 12.854. g-1, respectively. The Khistawi cultivar recorded a significant difference in the carbohydrate content of leaf which reached 9.564 µg.g-1 compared to Zahdi cultivar. The results were also showed that superiority of the concentration was 1 g. L-1. palm -1 in all studied characteristics. The study showed that in the concentration of 2 g. L-1. Palm-1 of disper osmotic had significant difference in the most of studied characteristics. Bilateral and triple inequalities have a significant moral effect in all studied characteristics.

This study was conducted in one of the private orchards in the district of Abu Al-Khaseeb, Basrah province during the growing seasons 2017 - 2018 in order to examine the effect of spraying acidic whey, enzymatic whey and  magnetized and non-magnetized whey on date palm cultivars Phoenix dactylifera L. agricultural (yellow Shwithi and Al-Khdrawi). A Concentration of 100% of the whey was applied to the fruits. The results of the study showed the superiority of the yellow Shwithi and Al-Khdrawi regarding the Qualitative and Productive characteristics. There was a significant difference between the date palm cultivars regarding the length, diameter, the weight of fruit, dry matter, total and reduced sugars and fruit content of invertase enzyme were recorded 33.45 mm, 20.89 mm, 9.302 g, 37.685%, 50.28%, 36.09% and 2347 units/kg/ CO2. The spray treatment was characterized by enzymatic whey in most of the study treatments of fruit length, fruit weight, total sugars and invertase enzyme. It reached 34.55 mm, 9.883 g, 56.15% and 2005.3 units/kg/CO2. The results also showed the importance of bilateral interaction between the variety and spray treatment.

A New Technique

Algeria’s date palm (Phoenix dactylifera L) fruit is one of the most important exported products from non hydrocarbon sources. As other fresh or dry fruits, the dates (cv. Deglet Nour) are exposed to damage during storage. In our study, we will apply a postharvest treatment using a radiofrequency radiation as a new technique used on dates while evaluating its effect on date palm fruit quality. The results obtained reveal that the treatment was effective on the capacity of dates to maintain their pH, moisture content and ash percentage during the storage compared with the dates untreated. Likewise, it achieved complete disinfection of dates. As results, the radiofrequency presents a practical alternative to the actually techniques used on postharvest treatment.
