Effect of acid whey, enzymatic whey, magnetized and unmagnetized whey on the qualitative and productive traits of date palm

Abstract EN

This study was conducted in one of the private orchards in the district of AbuAl-Khaseeb, Basrah province during the growing seasons 2017 - 2018 in order to examinethe effect of spraying acidic whey, enzymatic whey and magnetized and non-magnetizedwhey 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 thestudy showed the superiority of the yellow Shwithi and Al-Khdrawi regarding theQualitative and Productive characteristics.

There was a significant difference between thedate palm cultivars regarding the length, diameter, the weight of fruit, dry matter, total andreduced 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 wascharacterized by enzymatic whey in most of the study treatments of fruit length, fruitweight, total sugars and invertase enzyme.

It reached 34.55 mm, 9.883 g, 56.15% and2005.3 units/kg/CO2.

The results also showed the importance of bilateral interactionbetween the variety and spray treatment.
