Cultivations of Ficus carica L. under Different Agricultural Regimes: Some Physiological Aspects

Abstract

The productivity of Ficus carica (fig) grown in Mediterranean conditions is one of the most important issues. Consequently, the aim was to evaluate the effect of different agricultural regimes on fig cultivations and how productivity gets affected. Nine orchards were selected then grouped into four ranks according to the applied agricultural regimes. The following parameters were measured: soil physical and chemical properties; some physiological properties (RUBISCO*LSu and SSu*, protein profile and total soluble sugars) in addition to the productivity of fig fruits. Results obtained revealed that the evaluated parameters differ significantly (p≤ 0.05) in relation to the ranks of agricultural regimes. Sand and clay percentages revealed a significant (p≤ 0.05) difference in rank IV with respect to other ranks. Ca recorded the highest significant mean differences with values of about 128.7 and 130.4 mg for ranks I and II, respectively. Nevertheless, fig agro-economic issue proceeded from the past; it is likely to be continued in the future with some adjustments of the agricultural regimes which cope with the best productivity.
