Abstract:
The study was conducted under the 1st agro-ecological zone conditions at Kassab Research Station in Lattakia, General Commission for Scientific Agricultural Research for the three seasons 2018-2019-2020. It aims to study the effect of conservation agriculture and supplemental irrigation on calcium (Ca) content apple fruits and their Firmness (Sd). Random block design with three replicates was used. Two major treatments (N, T): traditional agriculture and conservation agriculture, and two secondary treatments (R, S): rainfed agriculture and supplemental irrigation were used, respectively.The results showed that the treatment (NS): conservation agriculture and supplemental irrigation) was more significant at level 5% than other treatments in terms of (Ca) and (Sd), and their highest values were 0.081% and 10.8 (kg/cm2), respectively. This is due to the role of conservation agriculture in improving humic acids, reducing calcium leaching, maintaining soil moisture and raising water use efficiency, as well as the role of supplemental irrigation water in reducing water stress during critical stages, thus increasing uptake of nutrients and calcium as a result of the availability of an appropriate moisture content.
Keywords: conservation agriculture, supplement irrigation, apples, consistency.
