You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your zden. Three organic mulches Italian Stone Pine, Lentisk, a combination of Italian Stone Pine and Lentiskan inorganic mulch gravel and no mulch and two tree shelter types non-vented, vented and control were tested.

Reforestation efforts, in terms of production of lumber and industrial wood, both in quality and quantity, remain dependent on the application of appropriate silvicultural methods pruning, thinning. A linear model including the livestock sector state or privatefarm-herd-year of birth-lambing season, maternal age, and sex-mode of birth was used to identify the main sources of variation in the cheje of Barbarine.

Ina second inventory was carried out, where we noticed an increase ezen number of trees and consequently in volume which could be explained by a strong regeneration by sowing in the maquis, the enclaves and after the passage of fires and a lack of application of specific silviculture to these stands, something that we propose in this study that takes into account the social problem and able to ensure the sustainability, the preservation of the forest ecosystem and the production of wood.

Least squares solutions were used to estimate the performance adjustment coefficients for age of dam and sex-birth mode. Lancement d’une nouvelle application pour les smartphones dans le secteur agricole en Tunisie: A total of milk test days of 67 cows in herds during was used in this study.

The density at that time was plants per hectare and plants throughout the serial. The objectives of this study were 1 to identify the different shapes of lactation curves of Holstein cows under North Africa Tunisia prevailing production environments and 2 to estimate parameters of the most dominant lactation curves found by season. The REML method was used for estimating heritability. The incomplete gamma function was used to adjust milk lactation curves per calving season.
