Abstract
Foliar N and P content of olive trees have shown a gradual increase from the month of October till May.
Gradual decrease in leaf K content occurred between the months of October to February, where after a gradual but continuous increase in its content was noted till the month of May.
However, foliar Ca and Mg contents also registered an increase between the months of October to January, but thereafter, a continuous decrease in their content was evident till the month of May.
Relatively higher N, P and K contents were estimated during non- cropped year as compared to the cropped year.
But converse was true for Ca and Mg content.
Among different cultivars maximum values of foliar N, P, K, Ca and Mg were found in Frantoio, followed by Leccino.
Maximum values of leaf N, P, K, Ca, Mg ensured regular bearing behaviour of the cultivar whereas deficiencies of these nutrients tended to induce erratic bearing behaviour of the cultivar.
